This study aims to investigate the clinical characteristics of infections following induction chemotherapy for acute myeloid leukemia (AML) in children and identify risk factors associated with severe infections. Newly diagnosed children with AML treated at the Hematology Oncology Center of Beijing Children's Hospital affiliated to Capital Medical University (referred to as the "Beijing ward") and Baoding Hospital of Beijing Children's Hospital (referred to as the "Baoding ward") between November 2019 and August 2022 were enrolled. The diagnosis and treatment of the patients were carried out in accordance with the CCLG-AML 2019 protocol. Their essential information and infection-related indicators were collected. The various indicators between the two centers were compared. The incidence of infection in children with AML was 100%, with a severe infection rate of 15.3% and an infection-related mortality rate of 2.4%. Respiratory infections accounted for 39.7% of all infections events, and unspecified site infection for 32.2%. Bacterial infections were predominant at 51.2%. The bed unit area (BUA) varied significantly with 4.1 m 2 in the Beijing ward and 10 m 2 in the Baoding ward. Significant differences were observed in gastrointestinal infections (P < 0.001) and severe infections (P = 0.014) between the two wards. Several factors were identified as risk factors for severe infections, including BUA difference (OR = 4.353, 95% CI: 1.078-17.578), time of entering neutropenia phase after chemotherapy (OR = 6.369, 95% CI: 1.713-23.675) and bloodstream infection (OR = 7.466, 95% CI: 1.889-29.507). Respiratory tract infections and infections of unspecified site are most common during induction phase for pediatric AML. Bacteria, especially G - bacteria, are the leading pathogens. Risk factors for severe infections include a small BUA, entering neutropenia phase ≤ 5.5 days after chemotherapy, and bloodstream infection. Recognizing these risk factors can aid in the early identification and intervention of severe infections., (© 2024.

Purpose: With advances in chemotherapy, conversion surgery is often performed for initially unresectable colorectal cancer liver metastasis (CLM). However, unexpected posthepatectomy liver failure (PHLF) is sometimes associated with chemotherapy-associated liver injuries following long-term chemotherapy. We aimed to identify predictive factors for PHLF after conversion surgery for initially unresectable CLM., Methods: We retrospectively identified 774 consecutive patients who underwent initial liver resections for histologically confirmed CLMs between 2010 and 2019 at our institute. We enrolled 107 patients with initially unresectable CLMs. Clinicopathological characteristics were evaluated to determine their association with PHLF. Logistic regression analysis was performed to analyze the predictors of PHLF., Results: Among the 107 patients, PHLF occurred in 15 cases (14%). Multivariate analysis revealed that splenomegaly during preoperative chemotherapy (> 135%) was an independent risk factor for PHLF (P = 0.002; odds ratio 14.30; 95% confidence interval 2.69-76.08). In the analysis limited to the splenomegaly group, lower platelet counts, increased blood loss and operative times, and large liver resection areas (> 100 cm 2 ) were significant risk factors for PHLF (P = 0.018, 0.043, 0.020, and 0.024, respectively). Among them, a liver resection area > 100 cm 2 can be calculated preoperatively and correlate with a complex hepatectomy., Conclusion: These findings could help predict PHLF after conversion surgery and induction chemotherapy for initially unresectable CLMs. Careful decisions, including detailed procedures and timing of hepatectomy, should be made before conversion hepatectomy in patients who develop splenomegaly after induction chemotherapy and require complex hepatectomies with a large liver resection area., (© 2024.

Objective: To evaluate the association between deficiency of vitamin A or D at diagnosis of pediatric acute lymphoblastic leukemia (ALL) and subsequent infectious complications during induction therapy., Study Design: We conducted an institutional review board-approved, retrospective cohort study of children with newly diagnosed ALL from 2007 to 2017 at St. Jude Children's Research Hospital. We measured vitamin D, vitamin D binding protein, retinol binding protein as a surrogate for vitamin A, and immunoglobulin isotypes in serum obtained at ALL diagnosis, and we assessed the association between vitamin deficiencies or levels and infection-related complications during the 6-week induction phase using Cox regression models., Results: Among 378 evaluable participants, vitamin A and D deficiencies were common (43% and 17%, respectively). Vitamin D deficiency was associated with higher risks of febrile neutropenia (adjusted hazard ratio [aHR], 1.7; P = .0072), clinically documented infection (aHR, 1.73; P = .025), and likely bacterial infection (aHR, 1.86; P = .008). Conversely, vitamin A deficiency was associated solely with a lower risk of sepsis (aHR, 0.19; P = .027)., Conclusions: In this retrospective study, vitamin D deficiency was associated with an increased risk of common infection-related complications during induction therapy for ALL. Additional studies are warranted to evaluate whether vitamin D supplementation could mitigate this effect., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Importance: The clinical effects of risankizumab (a monoclonal antibody that selectively targets the p19 subunit of IL-23) for the treatment of ulcerative colitis are unknown., Objective: To evaluate the efficacy and safety of risankizumab when administered as an induction and a maintenance therapy for patients with ulcerative colitis., Design, Setting, and Participants: Two phase 3 randomized clinical trials were conducted. The induction trial was conducted at 261 clinical centers (in 41 countries) and enrolled 977 patients from November 5, 2020, to August 4, 2022 (final follow-up on May 16, 2023). The maintenance trial was conducted at 238 clinical centers (in 37 countries) and enrolled 754 patients from August 28, 2018, to March 30, 2022 (final follow-up on April 11, 2023). Eligible patients had moderately to severely active ulcerative colitis; a history of intolerance or inadequate response to 1 or more conventional therapies, advanced therapies, or both types of therapies; and no prior exposure to risankizumab., Interventions: For the induction trial, patients were randomized 2:1 to receive 1200 mg of risankizumab or placebo administered intravenously at weeks 0, 4, and 8. For the maintenance trial, patients with a clinical response (determined using the adapted Mayo score) after intravenous treatment with risankizumab were randomized 1:1:1 to receive subcutaneous treatment with 180 mg or 360 mg of risankizumab or placebo (no longer receiving risankizumab) every 8 weeks for 52 weeks., Main Outcomes and Measures: The primary outcome was clinical remission (stool frequency score ≤1 and not greater than baseline, rectal bleeding score of 0, and endoscopic subscore ≤1 without friability) at week 12 for the induction trial and at week 52 for the maintenance trial., Results: Among the 975 patients analyzed in the induction trial (aged 42.1 [SD, 13.8] years; 586/973 [60.1%] were male; and 677 [69.6%] were White), the clinical remission rates at week 12 were 132/650 (20.3%) for 1200 mg of risankizumab and 20/325 (6.2%) for placebo (adjusted between-group difference, 14.0% [95% CI, 10.0%-18.0%], P < .001). Among the 548 patients analyzed in the maintenance trial (aged 40.9 [SD, 14.0] years; 313 [57.1%] were male; and 407 [74.3%] were White), the clinical remission rates at week 52 were 72/179 (40.2%) for 180 mg of risankizumab, 70/186 (37.6%) for 360 mg of risankizumab, and 46/183 (25.1%) for placebo (adjusted between-group difference for 180 mg of risankizumab vs placebo, 16.3% [97.5% CI, 6.1%-26.6%], P < .001; adjusted between-group difference for 360 mg of risankizumab vs placebo, 14.2% [97.5% CI, 4.0%-24.5%], P = .002). No new safety risks were detected in the treatment groups., Conclusion and Relevance: Compared with placebo, risankizumab improved clinical remission rates in an induction trial and in a maintenance trial for patients with moderately to severely active ulcerative colitis. Further study is needed to identify benefits beyond the 52-week follow-up., Trial Registration: ClinicalTrials.gov Identifiers: NCT03398148 and NCT03398135.

Background: Previous studies have reported that rituximab (RTX) therapy might be beneficial in reducing relapse rates in patients with IgG4-related disease (IgG4-RD). Therefore, we aimed to systematically assess the efficacy and safety of RTX induction treatment and the effect of RTX maintenance in patients with IgG4-RD., Methods: The protocol was registered in the PROSPERO (CRD42023427352). PubMed, Embase, the Cochrane database, Scopus, and the Web of Science were interrogated to identify studies that evaluated the impact of RTX on prognosis in IgG4-RD. We explored the impact of various subgroups of factors on relapse outcomes and focused on the possible role of maintenance therapy in reducing relapse rates. The pooled incidence of adverse events of RTX therapy and the influencing factors have also been evaluated., Results: Eighteen studies comprising 374 patients (mean age 56.0 ± 8.7 years; male 73.7 %) with a mean follow-up duration of 23.4 ± 16.3 months were included. The pooled estimate of the response rate, complete remission rate, overall relapse rate, adverse event rate, and serious adverse event rate of RTX induction therapy were 97.3 % (95 % CI, 94.7 %-99.1 %), 55.8 % (95 % CI, 39.6 %-71.3 %), 16.9 % (95 % CI, 8.7 %-27.1 %), 31.6 % (95 % CI, 16.7 %-48.9 %) and 3.9 % (95 % CI, 0.8 %-8.9 %), respectively. In subgroup analysis, the pooled relapse rate was significantly lower in studies with maintenance than without maintenance (2.8% vs 21.5 %, p < 0.01). Pooled Kaplan-Meier relapse curves also demonstrated that RTX maintenance therapy provided a better prognosis., Conclusions: RTX induction therapy appears to have satisfactory efficacy in the induction of remission in IgG4-RD. In addition, prophylactic RTX maintenance therapy after induction may be beneficial in preventing relapse of IgG4-RD., Competing Interests: Declaration of competing interest All authors declare no competing interests., (Copyright © 2024.

Atypical hemolytic uremic syndrome (aHUS) is a complement-mediated thrombotic microangiopathy sometimes associated with germline variants in genes of the complement system. Clinical findings of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury arise due to aberrant complement protein activation in the circulation. A 13-month-old boy with metastatic neuroblastoma (NB) developed aHUS during his first cycle of induction chemotherapy with germline testing revealing a complement factor H (CFH) gene mutation, currently classified as a variant of uncertain significance (VUS). Now he is in disease remission after successful complement blockade therapy, thus highlighting a unique presentation of aHUS in a patient with newly diagnosed NB., (© 2024 Wiley Periodicals LLC.)

Posttransplant lymphoproliferative disorder (PTLD) poses a significant concern in Epstein-Barr virus (EBV)-negative patients transplanted from EBV-positive donors (EBV R-/D+). Previous studies investigating the association between different induction agents and PTLD in these patients have yielded conflicting results. Using the Organ Procurement and Transplant Network database, we identified EBV R-/D+ patients >18 years of age who underwent kidney-alone transplants between 2016 and 2022 and compared the risk of PTLD with rabbit antithymocyte globulin (ATG), basiliximab, and alemtuzumab inductions. Among the 6620 patients included, 64.0% received ATG, 23.4% received basiliximab, and 12.6% received alemtuzumab. The overall incidence of PTLD was 2.5% over a median follow-up period of 2.9 years. Multivariable analysis demonstrated that the risk of PTLD was significantly higher with ATG and alemtuzumab compared with basiliximab (adjusted subdistribution hazard ratio [aSHR] = 1.98, 95% confidence interval [CI] 1.29-3.04, P = .002 for ATG and aSHR = 1.80, 95% CI 1.04-3.11, P = .04 for alemtuzumab). However, PTLD risk was comparable between ATG and alemtuzumab inductions (aSHR = 1.13, 95% CI 0.72-1.77, P = .61). Therefore, the risk of PTLD must be taken into consideration when selecting the most appropriate induction therapy for this patient population., (Copyright © 2024 American Society of Transplantation & American Society of Transplant Surgeons.

Background: Few studies regarding infectious causes of febrile neutropenia (FN) in Mexico are available., Aims: We aimed to describe clinical and microbiological characteristics of FN episodes during induction chemotherapy in adults with acute leukemia., Methods and Results: This retrospective cohort from a Mexican tertiary care center included adults with newly diagnosed acute leukemia between January 2014, and December 2018. Clinical and microbiological characteristics were summarized using descriptive statistics. Univariate analyses for associations between clinical characteristics and FN and/or death were made; logistic regression analysis was performed to assess relationships with FN. Kaplan-Meier survival estimates were modeled for antimicrobial prophylaxis and FN. Ninety-five patients were included. Median age was 28 (IQR 20-43), 49 (52%) were males, and 74 (78%) developed FN (74/95). Among these, 98% had an identified source of infection (73/74) and 65% had >1. Common infections were urinary tract infection (24%), bacterial sinusitis (20%), and bacterial pneumonia (19%). Gram-negatives were the most frequently isolated microorganisms (69%), followed by Gram-positives (21%), and fungi (9%). Antimicrobial prophylaxis was inversely associated with FN (aOR = 0.07, CI 0.008-0.060, p = 0.02). Invasive fungal diseases were associated with 30-day mortality (aOR = 9.46, 95% CI 1.66-54.05)., Conclusion: Infections caused 98% of the FN episodes. Gram-negative bacteria are the most common pathogens., (© 2024 The Author(s). Cancer Reports published by Wiley Periodicals LLC.)

Background: Thalidomide-containing regimens cause adverse events (AEs) that may require a reduction in treatment intensity or even treatment discontinuation in patients with multiple myeloma. As thalidomide toxicity is dose-dependent, identifying the most appropriate dose for each patient is essential., Aims: This study aimed to investigate the effects of a thalidomide dose step-up strategy on treatment response and progression-free survival (PFS)., Methods and Results: This prospective observational study included 93 patients with newly diagnosed multiple myeloma (NDMM) who received bortezomib, thalidomide, and dexamethasone (VTD). The present study assessed the incidence of thalidomide dose reduction and discontinuation, the overall dose intensity, and their effects on therapeutic efficacy. Furthermore, this study used Cox proportional hazard models to analyze the factors contributing to thalidomide intolerability. The results showed the overall response rates in all patients and the evaluable patients were 78.5% and 98.7%, respectively. The median PFS in the study cohort was not reached. The most common thalidomide-related AEs were constipation (32.3%) and skin rash (23.7%), resulting in dose reduction and discontinuation rates of 22.6% and 21.5%, respectively. The responders had a significantly higher average thalidomide dose intensity than the nonresponders (88.6% vs. 42.9%, p < .001)., Conclusion: The thalidomide dose step-up approach is a viable option for patients with NDMM receiving VTD induction therapy with satisfactory efficacy and tolerability. However, thalidomide intolerance may lead to dose reduction or discontinuation due to unpredictable AEs, leading to lower dose intensity and potentially inferior treatment outcomes. In addition to a dose step-up strategy, optimal supportive care is critical for patients with multiple myeloma receiving VTD induction therapy., (© 2024 The Author(s).

The antiangiogenic agent apatinib has been shown to clinically improve responses to immune checkpoint inhibitors in several cancer types. Patients with N3 nasopharyngeal carcinoma have a high risk of distant metastasis, however, if the addition of immunotherapy to standard treatment could improve efficacy is unclear. In this phase II clinical trial (ChiCTR2000032317), 49 patients with stage T any N3M0 nasopharyngeal carcinoma were enrolled and received the combination of three cycles of induction chemotherapy, camrelizumab and apatinib followed by chemoradiotherapy. Here we report on the primary outcome of distant metastasis-free survival and secondary end points of objective response rate, failure-free survival, locoregional recurrence-free survival, overall survival and toxicity profile. After induction therapy, all patients had objective response, including 13 patients (26.5%) with complete response. After a median follow-up of 28.7 months, the primary endpoint of 1-year distant metastasis-free survival was met for the cohort (1-year DMFS rate: 98%). Grade≥3 toxicity appeared in 32 (65.3%) patients, with the most common being mucositis (14[28.6%]) and nausea/vomiting (9[18.4%]). In this work, camrelizumab and apatinib in combination with induction chemotherapy show promising distant metastasis control with acceptable safety profile in patients with stage T any N3M0 nasopharyngeal carcinoma., (© 2024.

Thromboembolism (TE) is associated with reduced survival in pediatric acute lymphoblastic leukemia (ALL). It has been hypothesized that TE might signal leukemic aggressiveness. The objective was to determine risk factors for TE during ALL induction (TE ind ) therapy and whether TE ind is associated with treatment refractoriness. This retrospective cohort study using the population-based Cancer in Young People Canada (CYP-C) registry included children <15 years of age diagnosed with ALL (2000-2019) and treated at one of 12 Canadian pediatric centers outside of Ontario. Univariate and multivariable logistic regression models were used to determine risk factors for TE ind and whether TE ind predicted induction failure and ALL treatment intensification. The impact of TE ind on overall and event-free survival was estimated using Cox proportional hazard regression models. The study included 2589 children, of which 45 (1.7%) developed a TE ind . Age (<1 year and ≥10 years vs. 1-<10 years), T-cell phenotype, high-risk ALL, and central nervous system involvement were all associated with TE ind in univariate analysis. Age and T-cell phenotype remained independent predictors of TE ind in multivariable analysis. Induction failure occurred in 53 patients (2.1%). TE ind was not associated with induction failure (OR: not estimable) or treatment intensification (adjusted OR [95% CI]: 0.66 [0.26-1.69]). TE ind was independently associated with overall survival (adjusted HR [95% CI]: 2.54 [1.20-5.03]) but not event-free survival (adjusted HR [95% CI] 1.86 [0.98-3.51]). In this population-based study of children treated with contemporary chemotherapy protocols, TE ind was associated with age and T-cell phenotype and mortality but did not predict induction failure., (© 2024 The Authors.

Background and Purpose: Nab-paclitaxel is a promising albumin-bound paclitaxel with a therapeutic index superior to that of docetaxel, but the optimal dose of nab-paclitaxel combined with cisplatin and capecitabine as induction chemotherapy followed by concurrent chemoradiotherapy for patients with locally advanced nasopharyngeal carcinoma remains unknown., Materials and Methods: This was an open-label, single-arm study investigating the safety and efficacy of nab-paclitaxel + cisplatin + capecitabin as IC for three cycles, followed by cisplatin CCRT, conducted by using the standard "3 + 3" design in LA-NPC. If more than one-third of the patients in a cohort experienced dose-limiting toxicity (DLT), the dose used in the previous cohort was designated the maximum tolerated dose (MTD). The recommended phase 2 dose (RP2D) was defined as one level below the MTD., Results: From 29 May 2021 to 17 March 2022, 19 patients with LA-NPC were enrolled, one patient withdrew informed consent. Two DLTs occurred in cohort 4 (grade 4 febrile neutropenia and grade 3 peripheral neuropathy), and an MTD was established as 225 mg/m 2 . The most frequent grade 3 or 4 adverse events were neutropenia (16.7 %), hypertriglyceridemia (16.7 %), leukopenia (5.6 %) and peripheral neuropathy (5.6 %) during IC., Conclusion: The RP2D is nab-paclitaxel 200 mg/m 2 on day 1, combined with cisplatin 75 mg/mg 2 on day 1 and capecitabin1000 mg/m 2 on days 1-14, twice a day, every 3 weeks, for three cycles as an IC regimen prior to CCRT., Trial Registration: ClinicalTrials.gov Identifier: NCT04850235., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Patients with high-risk neuroblastoma (HR-NB) exhibit suboptimal 5-year survival rates, leading to a widespread international preference for high-intensity chemotherapeutic regimens in these children. We analyzed the incidence and risk factors for complications during induction chemotherapy in children with HR-NB and tried to assist clinicians in predicting such complications and optimizing therapeutic strategy. The clinical data of children with HR-NB admitted to our hospital from January 2007 to December 2019 were retrospectively analyzed. The incidence, characteristics, and risk factors of complications (infection, hemorrhage, and chemotherapy-related adverse reactions (CRAR)) requiring hospitalization during induction chemotherapy in these children were explored. (1) A total of 108 patients with HR-NB were included in the final analysis. The overall infection rate was 92.6% (100/108), with the highest incidence of 71.3% observed during the first cycle. FN, bacterial infection, as well as fungal infection were common infectious complications in children with HR-NB during induction chemotherapy. (2) The overall hemorrhage rate was 24.1% (26/108), with the highest incidence of 14.8% also observed in the first cycle. Among the children with hemorrhage, there were 72% with bone marrow involved, while 65.0% of them had a high vanillylmandelic acid (VMA) value. And children with hemorrhage also exhibited neuron-specific enolase (NSE) ≥ 200 µg/L in 88.5% of cases and lactic dehydrogenase (LDH) ≥ 1000U/L in 73.1% of cases. (3) The incidence of CRAR rate was 100%, and 99.1% (107/108) patients experienced myelosuppression. The incidence of myelosuppression peaked in the third cycle, reaching up to 85.2%. Most children suffered severe myelosuppression existed with bone marrow metastases (76.3%), abnormal VMA (67.5%), and LDH ≥ 1000 U/L (60%). (4) Non-myelosuppressive adverse effects were observed in 75.9% children (82/108), with the highest incidence occurring in the third cycle at 42.6%. (5) Patients who experienced three types of complications had a lower median survival time (MST) of 54.4 months, a 3-year event-free survival (EFS) rate of (44.2 ± 10.7)%, and a 3-year overall survival (OS) rate of (75.8 ± 8.6)%, in comparison to those with only one or two complications, who had a higher MST of 59.5 months, a 3-year EFS rate of (73.5 ± 5.2)% (X 2  = 10.457, P = 0.001), and a 3-year OS rate of (84.8 ± 4.1)% (X 2  = 10.511, P = 0.001)., Conclusion: The presence of bone marrow involved and increased VMA were high-risk factors for infection, while NSE ≥ 200 µg/L and LDH ≥ 1000 U/L were high-risk factors for hemorrhage. For those children who had experienced severe myelosuppression, the presence of bone marrow metastases, increased VMA, and LDH ≥ 1000 U/L were their risk factors. The presence of bone involvement was a high-risk factor for children to have non-myelosuppressive adverse effects. Complications that arise during induction chemotherapy could negatively impact the children's prognosis and overall quality of life., What Is Known: • The high-risk neuroblastoma (HR-NB) had a worse prognosis; there was a general international preference for high-intensity chemotherapeutic regimens in the induction phase to these children., What Is New: • We analyzed the incidence and risk factors of complications during induction chemotherapy in children with HR-NB and tried to help clinicians predict such complications and adopt optimized therapeutic strategy., (© 2023.

Background: To investigate the prevalence and predictive factors of xerostomia during induction chemotherapy (IC) in patients with nasopharyngeal carcinoma (NPC)., Methods: We prospectively enrolled NPC patients who received IC between October 2020 and October 2021. The Visual Analogue Scale (VAS) and Xerostomia Inventory (XI) were used to evaluate the condition of xerostomia. The volume of the submandibular gland (SMG) was also calculated before and after IC., Results: Fifty-two patients were enrolled in this study. Of these patients, 32.7% (n = 17) experienced xerostomia before IC. There were 32 (61.5%) patients suffered from xerostomia after IC, including 21 (40.4%) patients with newly diagnosed xerostomia after IC and 11 (21.1%) patients complained their xerostomia aggravated in those with xerostomia before IC. The median XI scores increased from 11 (standard deviation [SD], 2.930) to 18 (SD 3.995), 16 (SD 3.605), and 17 (SD 4.331) after the first, second, and third cycles of IC, respectively. The median score of VAS also increased from 0 to 4 during the following three cycles of IC. In those with IC-related xerostomia, the SMG volume after IC was significantly decreased compared with those without IC-related xerostomia (P = 0.001). The reduction of the SMG volume after IC was the independent risk factor for xerostomia (P = 0.002)., Conclusion: Approximately two-thirds of NPC patients suffered from IC-related xerostomia and patients with a reduction of SMG volume after IC had a higher risk of xerostomia., (© 2023 Wiley Periodicals LLC.)

Although initial central nervous system (CNS) involvement is rarely detected in childhood acute lymphoblastic leukemia (ALL), risk-adapted CNS-directed therapy is essential for all patients. Treatment intensity depends on the initial CNS status. In the AIEOP-BFM ALL 2009 trial, patients with cytomorphologic detection of leukemic blasts in initial cerebrospinal fluid were classified as CNS2 or CNS3 and received five intrathecal doses of methotrexate (MTX) in induction therapy compared to patients with CNS1 status (no blasts detected) who received three doses. The impact of additional intrathecal (IT) MTX on systemic toxicity in induction therapy is unknown. Between June 1st 2010 and February 28th 2017, a total of 6,136 ALL patients aged 1-17 years were enrolled onto the AIEOP-BFM ALL 2009 trial. The effect of three versus five doses of IT MTX during induction therapy on the incidence of severe infectious complications was analyzed. Among 4,706 patients treated with three IT MTX doses, 77 (1.6%) had a life-threatening infection during induction as compared to 59 of 1,350 (4.4%) patients treated with five doses (P<0.001; Odds Ratio 2.86 [95% Confidence Interval 1.99-4.13]). In a multivariate regression model, treatment with additional IT MTX proved to be the strongest risk factor for life-threatening infections (Odds Ratio 2.85 [1.96-4.14]). Fatal infections occurred in 16 (0.3%) and 38 (1.6%) patients treated with three or five IT MTX doses, respectively (P<0.001). As the relevance of additional intrathecal MTX in induction for relapse prevention in CNS2 patients is unclear, doses of intrathecal therapy have been reduced for these patients. (Clinicaltrials.gov identifiers: NCT01117441 and NCT00613457).

Purpose: The objective of this study was to estimate the long-term survival, late toxicity profile, and quality of life of patients with locoregionally advanced nasopharyngeal carcinoma (NPC) treated with combined induction chemotherapy (IC) and concurrent chemoradiotherapy from a clinical trial focused on reducing the target volume of intensity modulated radiation therapy (IMRT)., Methods and Materials: This prospective, randomized clinical trial was conducted across 6 Chinese hospitals and included 212 patients with stage III-IVB NPC who were randomly allocated to a pre-IC or post-IC group. Eligible patients were treated with 2 cycles of IC + CCRT. All patients underwent radical IMRT. Gross tumor volumes of the nasopharynx were delineated according to pre-IC and post-IC tumor extent in the pre-IC and post-IC groups, respectively., Results: After a median follow-up of 98.4 months, 32 of 97 (32.9%) and 33 of 115 (28.7%) patients experienced treatment failure or died in the pre-IC and post-IC groups, respectively. None of the patients developed grade 4 late toxicity. Late radiation-induced toxicity predominantly manifested as grade 1 to 2 subcutaneous fibrosis, hearing loss, tinnitus, and xerostomia, whereas grade 3 late toxicity included xerostomia and hearing loss. The 5-year estimated overall, progression-free, locoregional recurrence-free, and distant metastasis-free survival rates in the pre-IC and post-IC groups were 78.2% versus 83.3%, 72.0% versus 78.1%, 90.2% versus 93.5%, and 78.1% versus 82.1%, respectively. The pre-IC group had a significantly higher incidence of xerostomia and hearing damage than the post-IC group. In terms of quality of life, compared with the pre-IC group, the post-IC group showed significant improvement in cognitive function (P = .045) and symptoms including dry mouth (P = .004), sticky saliva (P = .047), and feeling ill (P = .041)., Conclusions: After long-term follow-up, we confirmed that reducing the target volumes of IMRT after IC in locoregionally advanced NPC showed no inferiority in terms of the risk of locoregional relapse and potentially improved quality of life and alleviated late toxicity., (Copyright © 2023 Elsevier Inc.

Acute leukemias are complex diseases to treat and have a high mortality rate. The immunosuppression caused by chemotherapy also causes the patient to become susceptible to a variety of infections, including invasive fungal infections. Protocols established in many countries attempt to prevent these infections through the use of pharmacological antifungal prophylaxis. This systematic review and meta-analysis investigates the existing evidence for the use of antifungal prophylaxis in patients undergoing induction chemotherapy for acute leukemia, and how prophylaxis can affect treatment response and mortality. Through the use of a population-variable-outcome strategy, keywords were utilized to search online databases. The included studies were selected and the data was collected to develop descriptive results for all studies, and, for studies that met the criteria, a meta-analysis of the Relative Risk (RR) was analyzed for infection rates, in-hospital mortality, and complete remission. A total of 33 studies were included in this systematic review, with most studies presenting positive results (n = 28/33) from the use of antifungal prophylaxis. Using a random effects model, the pooled results of the meta-analysis presented lower invasive fungal infections in AML (RR: 0.527 (95% CI: 0.391; 0.709). p < 0.001). p < 0.001) and ALL (RR: 0.753 (95% CI: 0.574; 0.988). p = 0.041). when antifungal prophylaxis was used. No discernible difference was encountered in the rate of complete remission when using prophylaxis. Antifungal prophylaxis provides a lower risk of invasive fungal infections and in-hospital mortality in acute leukemia patients undergoing induction chemotherapy., (© 2023.

As a mainstay of treatment for acute lymphoblastic leukemia (ALL), vincristine's side effect profile is well known. Parallel administration of the antifungal fluconazole has been shown to interfere with the metabolism of vincristine, potentially resulting in increased side effects. We conducted a retrospective chart review to determine whether concomitant administration of vincristine and fluconazole during pediatric ALL induction therapy impacted the frequency of vincristine side effects, namely, hyponatremia and peripheral neuropathy. We also evaluated whether the incidence of opportunistic fungal infections was impacted by fluconazole prophylaxis. Medical charts of all pediatric ALL patients treated with induction chemotherapy at Children's Hospital and Medical Center in Omaha, NE, from 2013 to 2021 were retrospectively reviewed. Fluconazole prophylaxis did not significantly impact the rate of fungal infections. We found no correlation between fluconazole use and increased incidence of hyponatremia or peripheral neuropathy, which supports the safety of fungal prophylaxis with fluconazole during pediatric ALL induction therapy., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objectives: More than 50% patients develop emesis during induction therapy for acute myeloid leukaemia (AML). The addition of aprepitant for emesis control in children receiving induction for AML have not been explored., Methods: A single-institutional randomised, open-label trial (NCT02979548) was conducted where children between 5 and 18 years with the diagnosis of AML being planned for 3+7 induction regimen were included. All study participants received ondansetron (0.15 mg/kg) every 8 hours for 8 days starting 30 min prior to chemotherapy. Children belonging to aprepitant group additionally received aprepitant capsules (15-40 kg=days 1-3, 80 mg; >40 kg=day 1, 125 mg and days 2-3, 80 mg) starting from 1 hour prior to chemotherapy. The proportion of patients with complete response (CR) in chemotherapy induced vomiting (CIV) in acute phase (day 1-8), delayed phase (day 9-13), overall and initial 96 hours were recorded along with severity of vomiting and adverse effects., Results: Total 78 children were randomised (Aprepitant group: 37 and control group: 41). The proportion of patients with CR in CIV was significantly higher in Aprepitant group in acute phase (p=0.007), overall phase (p=0.007) and in initial 96 hours (p<0.001) but it was not different in delayed phase (p=0.07). The first episode of vomiting was also significantly delayed in aprepitant group (p=0.02). Adverse effect profile was similar in two groups., Conclusion: Aprepitant significantly improves emesis control in children receiving induction therapy for AML, especially in acute phase and should be routinely incorporated as part of antiemetic prophylaxis., Trial Registration Number: The study was registered at ClinicalTrials.gov (NCT02979548)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: The choice of induction therapy in kidney transplantation is often non-standardized and centre-specific. Clinicians can choose between depleting and non-depleting antibodies, which differ in their immunosuppressive capacity and the concomitant risk of infection. We herein present a standardized risk-stratified algorithm for induction therapy that might help to balance the risk of rejection and/or serious infection., Methods: Prior to kidney transplantation, patients were stratified into low-risk, intermediate-risk or high-risk according to our protocol based on immunologic risk factors. Depending on their individual immunologic risk, patients received basiliximab (low risk), antithymocyte globulin (intermediate risk) or low-dose alemtuzumab (high risk) for induction therapy. We analysed the results after 3 years of implementation of our risk-stratified induction therapy protocol at our kidney transplant centre., Results: Between 01/2017 and 05/2020, 126 patients were stratified in accordance with our protocol (low risk/intermediate risk/high risk: 69 vs. 42 vs. 15 patients). The median follow-up time was 1.9 [1.0-2.5] years. No significant difference was observed in rejection rate and allograft survival (low risk/intermediate risk/high risk: 90.07% vs. 80.81% vs. 100% after 3 years (p > 0.05)) among the groups. The median eGFR at follow-up was (low risk/intermediate risk/high risk) 47 [33-58] vs 58 [46-76] vs 44 [22-55] ml/min/1.73 m 2 . Although the rate of viral and bacterial infections did not differ significantly, we observed a higher rate of opportunistic fungal infections with alemtuzumab induction., Conclusions: Our strategy offers facilitated and individualized choice of induction therapy in kidney transplantation. We propose further evaluation of our algorithm in prospective trials., (© 2023. The Author(s).)

Hypothyroidism as a long-term complication in cancer survivors has been an issue, but few studies have focused on changes in thyroid hormone levels during chemotherapy for leukaemia. This retrospective study was conducted to assess the characteristics of children with acute lymphoblastic leukaemia (ALL) and hypothyroidism during induction chemotherapy and to investigate the prognostic value of hypothyroidism in ALL. Patients with a detailed thyroid hormone profile at ALL diagnosis were enrolled. Hypothyroidism was defined as low serum levels of free tetraiodothyronine (FT4) and/or free triiodothyronine (FT3). The Kaplan-Meier method was used to create survival curves, and multivariate Cox regression analysis was used to screen prognostic factors associated with progression-free survival (PFS) and overall survival (OS). There were 276 children eligible for the study, and 184 patients (66.67%) were diagnosed with hypothyroidism, including 90 cases (48.91%) with functional central hypothyroidism and 82 cases (44.57%) with low T3 syndrome. Hypothyroidism was correlated with the dosages of L-Asparaginase (L-Asp) (P = .004) and glucocorticoids (P = .010), central nervous system (CNS) status (P = .012), number of severe infections (grade 3, 4 or 5) (P = .026) and serum albumin level (P = .032). Hypothyroidism was an independent prognostic factor for PFS in ALL children (P = .024, 95% CI: 1.1-4.1). We conclude that hypothyroidism is commonly present in ALL children during induction remission, which is related to chemotherapy drugs and severe infections. Hypothyroidism was a predictor of poor prognosis in childhood ALL., (© 2023 UICC.)

Purpose: To compare the acute toxicity of two different induction chemotherapy (IndCT) regimen followed by the same IMRT in patients with advanced nasopharyngeal carcinoma (NPC)., Materials and Methods: From July 2015 to December 2016, 110 NPC patients with stage III-IV diseases were prospectively randomized to receive either a conventional triweekly cisplatin + 5-fluorouracil (PF) for 3 cycles or weekly P-F for 10 doses, followed by the same IMRT to both arms. The primary endpoints of this study were grade 3/4 and any grade acute toxicities during IndCT period. The secondary endpoints included tumor response and various survivals., Results: Baseline patient characteristics were comparable in both groups. Patients who received weekly P-F experienced significant reduction of grade 3/4 acute toxicities, including neutropenia (12.7% vs. 40.0%, P = 0.0012), anorexia (0% vs. 14.6%, P = 0.0059), mucositis (0% vs. 14.6%, P = 0.0059), and hyponatremia (0% vs. 16.4%, P = 0.0027), compared with the triweekly PF group, resulting in fewer IndCT interruptions (1.8% vs. 16.4%, P = 0.0203), emergency room visits (0% vs. 12.7%, P = 0.0128), and additional hospitalizations (0% vs. 9.1%, P = 0.0568). The acute toxicities during IMRT period were similar. Weekly P-F arm had higher complete response rates (83.6% vs. 61.8%, P = 0.0152) and lower relapse rates (16.4% vs. 33.3%, P = 0.0402) after a median follow-up of 67 months. Kaplan-Meier survival analyses revealed a better trend of locoregional failure-free (P = 0.0892), distant metastasis failure-free (P = 0.0775), and progression-free (P = 0.0709) survivals, favoring the weekly P-F arm., Conclusion: IndCT of weekly schedule does reduce acute toxicities without compromised tumor response and survivals., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Purpose: Sinonasal tumours are rare diseases with poor prognosis. Multimodal approach including surgery is widely used, although no standard therapy has been established in prospective trials. This study assessed activity and safety of an innovative integration of multimodality treatment-induction chemotherapy (ICT), surgery and radiotherapy (RT)-modulated by histology and response to ICT., Methods: Patients with untreated, operable sinonasal tumours with selected histotypes (squamous cell carcinoma, intestinal-type adenocarcinoma, sinonasal undifferentiated and neuroendocrine carcinoma, olfactory neuroblastoma) were enrolled in a single-arm, phase II, multicenter clinical trial. Patients were treated with up to 5 ICT cycles, whose regimen was selected according to histotype, followed either by curative chemo-RT for pts with ≥80% reduction of initial tumour diameter or surgery and adjuvant (chemo)RT. Photon and/or proton/carbon ion-based RT was employed according to the disease site and stage. Primary end-point was 5-year progression-free survival (PFS), secondary end-points were overall survival (OS), ICT objective response rate (ORR) per RECIST 1.1 and safety., Results: Thirty-five patients were evaluable for primary end-point. Fourteen patients (40%) were treated with definitive (CT)RT and 20 (57%) underwent surgery. Five-year PFS was 38% (95% confidence interval [CI], 21-69), with a median PFS of 26 months. Five-year OS was 46% (95% CI, 28-75), with a median OS of 36 months. Three-year PFS-OS for pts achieving PR/CR versus stable disease (SD)/PD to ICT were 49.8-57% versus 43.2-53%, respectively. Three-year PFS for patients achieving major volumetric partial response (≥80% reduction of initial tumour volume, major partial volumetric response [mPRv]) versus non-mPRv were 82% versus 28% and 3-year OS were 92% versus 36% (p value 0.010 and 0.029, respectively). The ORR to ICT was 54% and 60% across all histotypes and in the sinonasal undifferentiated carcinoma (SNUC) subpopulation, respectively, with 6/15 SNUCs (40%) achieving mPRv., Conclusion: Treatment of advanced sinonasal cancer with histology-driven ICT followed by (CT)RT in responsive patients was feasible. Overall, these findings suggest a possible role of ICT as the primary approach in newly diagnosed, resectable sinonasal tumours-especially SNUC-to select patients with favourable prognosis.

Background: Mirikizumab, a p19-directed antibody against interleukin-23, showed efficacy in the treatment of ulcerative colitis in a phase 2 trial., Methods: We conducted two phase 3, randomized, double-blind, placebo-controlled trials of mirikizumab in adults with moderately to severely active ulcerative colitis. In the induction trial, patients were randomly assigned in a 3:1 ratio to receive mirikizumab (300 mg) or placebo, administered intravenously, every 4 weeks for 12 weeks. In the maintenance trial, patients with a response to mirikizumab induction therapy were randomly assigned in a 2:1 ratio to receive mirikizumab (200 mg) or placebo, administered subcutaneously, every 4 weeks for 40 weeks. The primary end points were clinical remission at week 12 in the induction trial and at week 40 (at 52 weeks overall) in the maintenance trial. Major secondary end points included clinical response, endoscopic remission, and improvement in bowel-movement urgency. Patients who did not have a response in the induction trial were allowed to receive open-label mirikizumab during the first 12 weeks of the maintenance trial as extended induction. Safety was also assessed., Results: A total of 1281 patients underwent randomization in the induction trial, and 544 patients with a response to mirikizumab underwent randomization again in the maintenance trial. Significantly higher percentages of patients in the mirikizumab group than in the placebo group had clinical remission at week 12 of the induction trial (24.2% vs. 13.3%, P<0.001) and at week 40 of the maintenance trial (49.9% vs. 25.1%, P<0.001). The criteria for all the major secondary end points were met in both trials. Adverse events of nasopharyngitis and arthralgia were reported more frequently with mirikizumab than with placebo. Among the 1217 patients treated with mirikizumab during the controlled and uncontrolled periods (including the open-label extension and maintenance periods) in the two trials, 15 had an opportunistic infection (including 6 with herpes zoster infection) and 8 had cancer (including 3 with colorectal cancer). Among the patients who received placebo in the induction trial, 1 had herpes zoster infection and none had cancer., Conclusions: Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. Opportunistic infection or cancer occurred in a small number of patients treated with mirikizumab.

Background: Upadacitinib, an oral selective Janus kinase (JAK) inhibitor, is under investigation for the treatment of Crohn's disease., Methods: In two phase 3 induction trials (U-EXCEL and U-EXCEED), we randomly assigned patients with moderate-to-severe Crohn's disease to receive 45 mg of upadacitinib or placebo (2:1 ratio) once daily for 12 weeks. Patients who had a clinical response to upadacitinib induction therapy were randomly assigned in the U-ENDURE maintenance trial to receive 15 mg of upadacitinib, 30 mg of upadacitinib, or placebo (1:1:1 ratio) once daily for 52 weeks. The primary end points for induction (week 12) and maintenance (week 52) were clinical remission (defined as a Crohn's Disease Activity Index score of <150 [range, 0 to 600, with higher scores indicating more severe disease activity]) and endoscopic response (defined as a decrease in the Simple Endoscopic Score for Crohn's Disease [SES-CD; range, 0 to 56, with higher scores indicating more severe disease] of >50% from baseline of the induction trial [or for patients with an SES-CD of 4 at baseline, a decrease of ≥2 points from baseline])., Results: A total of 526 patients underwent randomization in U-EXCEL, 495 in U-EXCEED, and 502 in U-ENDURE. A significantly higher percentage of patients who received 45-mg upadacitinib than those who received placebo had clinical remission (in U-EXCEL, 49.5% vs. 29.1%; in U-EXCEED, 38.9% vs. 21.1%) and an endoscopic response (in U-EXCEL, 45.5% vs. 13.1%; in U-EXCEED, 34.6% vs. 3.5%) (P<0.001 for all comparisons). At week 52 in U-ENDURE, a higher percentage of patients had clinical remission with 15-mg upadacitinib (37.3%) or 30-mg upadacitinib (47.6%) than with placebo (15.1%), and a higher percentage had an endoscopic response with 15-mg upadacitinib (27.6%) or 30-mg upadacitinib (40.1%) than with placebo (7.3%) (P<0.001 for all comparisons). Herpes zoster infections occurred more frequently in the 45-mg and 30-mg upadacitinib groups than in the respective placebo groups, and hepatic disorders and neutropenia were more frequent in the 30-mg upadacitinib group than in the other maintenance groups. Gastrointestinal perforations developed in 4 patients who received 45-mg upadacitinib and in 1 patient each who received 30-mg or 15-mg upadacitinib., Conclusions: Upadacitinib induction and maintenance treatment was superior to placebo in patients with moderate-to-severe Crohn's disease.

Objective: This study aims to evaluate the risk stratification among elderly Nasopharyngeal carcinoma (NPC) patients (≥60 years old) and select the beneficiaries from concurrent chemotherapy (CCRT) combined with induction chemotherapy (IC)., Materials and Methods: A total of 909 elderly non-metastatic NPC patients treated with cisplatin-based CCRT or IC + CCRT between January 2007 and December 2016 were included. Prognostic nomograms were generated according to clinical characteristics and serum biomarkers. The survival outcomes of patients treated with CCRT versus IC + CCRT were compared in three well-matched risk groups (high, medium, and low risk) after PSM analysis. Benefit of IC in people older or younger than 70 years and effect of different IC regimens and cycles on prognosis were analyzed., Results: Nomograms of overall survival (OS) (C-index: 0.64, 95% CI, 0.61-0.89) and disease special survival (DSS) (C-index: 0.65, 95% CI, 0.62-0.71) showed good prognostic accuracy. The nomogram for DSS included variables of age, gender, ACE, EBV DNA, N stage, and T stage. OS included variables of age, smoking history, ACE, ALB, EBV DNA, N stage, and T stage. The corresponding 5-year OS rates of high, medium and low risk groups were 87.4%, 82.2%, and 60.9%, respectively (p < 0.001), while the 5-year DSS rates were 92.2%, 84.3%, and 69.0%, respectively (p < 0.001). In the high risk group, IC + CCRT led to significantly higher 5-year OS and DSS rate compared with CCRT (5-year OS rate, 73.5% versus 51.8%, p = 0.006; 5-year DSS rate, 81.4% versus 61.3%, p = 0.002). While in the medium and low risk groups, OS and DSS were not significantly different (OS: p = 0.259, 0.186; DSS: p = 0.29, 0.094). Subgroup analysis showed in the high risk group, only people younger than 70 years old could benefit from IC. TPF and IC cycles of three could lead to the best survival results., Conclusion: Compared with CCRT, OS, and DSS among high risk elderly patients were significantly improved by the addition of IC in patients younger than 70 years old. TPF and three IC cycles were recommended., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

Objective: The purpose of this study was to compare the clinical outcomes and toxicities between induction chemotherapy (IC) + chemo-radiotherapy (CRT) and CRT alone in patients with locally advanced esophageal squamous cell carcinoma (ESCC), to explore the appropriate thoracic radiotherapy (TRT) timing after IC and to identify prognostic factors., Methods: 450 ESCC patients were included from September 2011 to December 2020, 238 of whom received IC/CRT. Propensity score matching was performed to balance potential confounders between the two groups. Multivariate Cox regression analysis was used to identify the independent prognostic factors., Results: Patients who received IC/CRT experienced improved overall survival (OS) (38.5 vs. 28.8 months) and progression-free survival (PFS) (41.0 vs. 22.0 months) before matching, with similar results after matching. In the IC/CRT group, early TRT had more favorable survival than late TRT both matching before and after. In subgroup analysis, early TRT combination concurrent chemotherapy had better OS and PFS than late TRT combination concurrent chemotherapy. In addition, early TRT had better survival benefits regardless of the N stage. Notably, the IC/CRT group and early TRT group had manageable toxicities reaction compared with CRT alone group and the late TRT group. The nomogram was developed to predict the OS and PFS based on multivariate analysis results. The C-index was 0.743 and 0.722, respectively., Conclusion: IC/CRT and early TRT could yield satisfactory clinical outcomes and controllable toxicities in locally advanced ESCC. The IC plus early concurrent CRT might be a promising treatment strategy for improving further survival in ESCC., (© 2023.

Background: Infectious complications reflect a major challenge in the treatment of patients with acute myeloid leukemia (AML). Both induction chemotherapy and epigenetic treatment with hypomethylating agents (HMA) are associated with severe infections, while neutropenia represents a common risk factor. Here, 220 consecutive and newly diagnosed AML patients were analyzed with respect to infectious complications dependent on treatment intensity and antifungal prophylaxis applied to these patients., Patients and Methods: We retrospectively analyzed 220 patients with newly diagnosed AML at a tertiary care hospital between August 2016 and December 2020. The median age of AML patients undergoing induction chemotherapy (n = 102) was 61 years (25-76 years). Patients receiving palliative AML treatment (n = 118) had a median age of 75 years (53-91 years). We assessed the occurrence of infectious complication including the classification of pulmonary invasive fungal disease (IFD) according to the EORTC/MSG criteria at diagnosis and until day 100 after initiation of AML treatment. Furthermore, admission to intensive care unit (ICU) and subsequent outcome was analyzed for both groups of AML patients, respectively., Results: AML patients subsequently allocated to palliative AML treatment have a significantly higher risk of pneumonia at diagnosis compared to patients undergoing induction chemotherapy (37.3% vs. 13.7%, P < 0.001) including a higher probability of atypical pneumonia (22.0% vs. 10.8%, P = 0.026). Furthermore, urinary tract infections are more frequent in the palliative subgroup at the time of AML diagnosis (5.1% vs. 0%, P = 0.021). Surprisingly, the incidence of pulmonary IFD is significantly lower after initiation of palliative AML treatment compared to the occurrence after induction chemotherapy (8.4% vs. 33.3%, P < 0.001) despite only few patients of the palliative treatment group received Aspergillus spp.-directed antifungal prophylaxis. The overall risk for infectious complications at AML diagnosis is significantly higher for palliative AML patients at diagnosis while patients undergoing induction chemotherapy have a significantly higher risk of infections after initiation of AML treatment. In addition, there is a strong correlation between the occurrence of pneumonia including atypical pneumonia and pulmonary IFD and the ECOG performance status at diagnosis in the palliative AML patient group. Analysis of intensive care unit (ICU) treatment (e.g. in case of sepsis or pneumonia) for both subgroups reveals a positive outcome in 10 of 15 patients (66.7%) with palliative AML treatment and in 15 of 18 patients (83.3%) receiving induction chemotherapy. Importantly, the presence of infections and the ECOG performance status at diagnosis significantly correlate with the overall survival (OS) of palliative AML patients (315 days w/o infection vs. 69 days with infection, P 0.0049 and 353 days for ECOG < 1 vs. 50 days for ECOG > 2, P < 0.001, respectively) in this intent-to-treat analysis., Conclusion: The risk and the pattern of infectious complications at diagnosis and after initiation of AML therapy depends on age, ECOG performance status and subsequent treatment intensity. A comprehensive diagnostic work-up for identification of pulmonary IFD is indispensable for effective treatment of pneumonia in AML patients. The presence of infectious complications at diagnosis contributes to an inferior outcome in elderly AML patients., (© 2022. The Author(s).)

Objectives: Anti-melanoma differentiation-associated protein-5 (MDA5) autoantibodies (Abs) are associated with rapidly progressive interstitial lung disease (RP-ILD) in dermatomyositis (DM). Because the addition of plasma exchange (PE) and rituximab (RTX) to triple therapy is inadequate in severe cases, we treat such cases with intensive induction therapy (IIT) combining all these options with tofacitinib (TOF). In this study, we investigated the poor prognostic factors and the efficacy and safety of IIT., Methods: Thirty-three patients diagnosed with anti-MDA5 Ab-positive DM in our institution between 2014 and 2021 were included. The clinical characteristics of poor prognosis were retrospectively analysed using principal component analysis (PCA), and the outcomes of IIT were analysed in terms of survival, assessed using the Kaplan-Meier test, and adverse events., Results: Although triple therapy with RTX, PE, or intravenous immunoglobulin was administered before the introduction of IIT, eight of 12 RP-ILD cases with a ferritin level >400 ng/mL (mean, 2,342) died within a median of 2.5 months. PCA revealed distinct clusters for prognosis, and age and serum ferritin were leading predictors of the prognosis. IIT, consisting of combinations of triple therapy with higher doses of methylprednisolone, PE, RTX, and TOF, was applied to eight patients (mean ferritin, 3,558). Although two patients died even with these regimens, a significant improvement in survival was documented. Several IIT-related adverse events were observed, including viral and fungal infections and cytopenia., Conclusions: IIT significantly improved the survival of patients with severe anti-MDA5 Ab-positive RP-ILD. Although infections are noted, their benefits outweigh the risks in younger patients with high serum ferritin levels.

Background: Induction chemotherapy (IC) comprising docetaxel, cisplatin, and fluorouracil (TPF), combined with concurrent chemoradiotherapy (CCRT) effectively improves the survival rate of locally advanced nasopharyngeal carcinoma (LA-NPC). Selecting patients whose risk of tumor recurrence and metastasis is high and the appropriate chemotherapy intensity is a concern. We combined tumor-node-metastasis staging with the load of Epstein-Barr virus (EBV) after IC to select the individualized chemotherapy strength., Methods: The clinical data and prognostic factors of patients with stage III-IV LA-NPC treated with TPF IC combined with CCRT were analyzed retrospectively. The conventional treatment group received the standard three cycles TPF IC combined with CCRT. For the new treatment group, the cycles of IC were determined according to whether the EBV-DNA disappeared completely after a certain course of IC, if so, subsequent IC was stopped and the chemoradiotherapy stage was entered. Propensity score matching (PSM) was performed at a ratio of 1:1 to balance baseline characteristics. Survival outcomes and adverse events between the conventional treatment group and the new method treatment group were compared., Results: The study included 256 patients, among whom 192 were matched successfully into 96 pairs. The patients were followed up for a median of 51 months. The proportions of patients receiving three, two, and one cycle of IC after PSM in the routine and new treatment cohorts were 93.8%, 3.1%, 3.1% versus 21.9%, 49.0%, 24.0%, respectively. However, their 3-year distant metastasis-free survival, local recurrence-free survival, progression-free survival, and overall survival did not differ significantly. The incidence of grade 3-4 neutropenia toxicity in CCRT decreased significantly in patients receiving the new treatment method compared with that in the conventional treatment group (p = 0.026)., Conclusion: Combining TNM stage and EBV-DNA load after IC to determine the courses of IC in patients with LA-NPC did not alter the curative effect but decreased toxicity., (© 2022 The Authors.

Introduction: Although concurrent chemoradiotherapy is the standard of care for inoperable locally advanced head and neck cancer, induction chemotherapy is considered an alternative approach by head and neck oncologists worldwide., Aims: To evaluate the response to induction chemotherapy in terms of loco-regional control and treatment-related toxicity in inoperable locally advanced head and neck cancer patients., Materials and Methods: This prospective study was conducted on patients who received two to three cycles of induction chemotherapy. Following this, response assessment was performed clinically. Grading of radiation-induced oral mucositis and any interruptions in treatment were noted. At 8 weeks following treatment, magnetic resonance imaging-based radiological response assessment was performed using RECIST criteria version 1.1., Results: Our data revealed 57.7% complete response rate with induction chemotherapy, followed by chemoradiation therapy. We observed that post induction, 67.5% and 47.5% patients had reduction in T-stage (<0.001) and N-stage of disease (<0.001), respectively, with complete response more achieved in younger patients (≤50 years). Chemotherapy-induced bone marrow suppression and febrile neutropenia occurred in 7.5% patients. We demonstrated that a higher grade of radiation-induced mucositis was noticed among those receiving three cycles of induction chemotherapy (ICT) and aged >50 years., Conclusion: We conclude that induction chemotherapy could still be a viable option for down-staging unresectable locally advanced disease, especially for younger patients in terms of better treatment response and tolerability. The number of cycles of ICT seems to influence radiation-induced mucositis. This study underscores the need for further studies to determine the exact role of ICT in locally advanced head and neck cancer.

Objective: Concurrent chemoradiotherapy (CTRT) is the standard treatment for patients with unresectable, nonmetastatic Locally advanced squamous cell cancer of head and neck (LASCCHN). The aim of this study to compare the efficacy and toxicity of induction chemotherapy (ICT) followed by CTRT versus standard CTRT alone in patients with LASCCHN., Materials and Methods: Between January 2017 and September 2017, 100 patients with LASCCHN (Stage III and IV) were randomly assigned to two arms: 50 patients in each. Arm A treated by standard CTRT alone (a total 66 Gy in 33fr 2 Gy/# administered daily 5 days/week with 3 weekly inj. cisplatin 100 mg/m 2 divided in two days) and Arm B received two cycles of ICT (TPF - inj. paclitaxel 175 mg/m2 on day 1, cisplatin 100 mg/m2 divided in 2 days and inj. 5FU 1 gm/m2 iv d1 and d2 ) followed by same CTRT. Assessment was done weekly during RT and 1, 3, 6, 12, and 18 months posttreatment for treatment response, toxicities, and progression-free survival (PFS)., Results: Total response was observed 79.1% and 82.1% in Arm A and Arm B, respectively (P = 0.705) at 6-8 weeks after the completion of treatment. Acute toxicities were significantly higher in ICT arm. The 18 months PFS was 57% versus 55% in Arm A and Arm B, respectively (x 2 = 0.039, P = 0.8414)., Conclusion: Among the patients followed, this study failed to show benefit of ICT-CTRT over CTRT alone in patients of LASCCHN., Competing Interests: None

Purpose: Concurrent chemoradiotherapy (CCRT) is a standard treatment choice for locally advanced hypopharyngeal carcinoma. The aim of this study was to investigate whether induction chemotherapy (IC) followed by CCRT is superior to CCRT alone to treat locally advanced hypopharyngeal carcinoma., Methods and Materials: Patients (n = 142) were randomized to receive two cycles of paclitaxel/cisplatin/5-fluorouracil (TPF) IC followed by CCRT or CCRT alone. The primary end point was overall survival (OS). The secondary end points included the larynx-preservation rate, progression-free survival (PFS), distant metastasis-free survival (DMFS), and toxicities., Results: Ultimately, 113 of the 142 patients were analyzed. With a median follow-up of 45.6 months (interquartile range 26.8-57.8 months), the 3-year OS was 53.1% in the IC + CCRT group compared with 54.8% in the CCRT group (hazard ratio, 1.004; 95% confidence interval, 0.573-1.761; P = 0.988). There were no statistically significant differences in PFS, DMFS, and the larynx-preservation rate between the two groups. The incidence of grade 3-4 hematological toxicity was much higher in the IC+ CCRT group than in the CCRT group (54.7% vs. 10%, P < 0.001)., Conclusions: Adding induction TPF to CCRT did not improve survival and the larynx-preservation rate in locally advanced hypopharyngeal cancer, but caused a higher incidence of acute hematological toxicities., Trial Registration: ClinicalTrials.gov , number NCT03558035.

BACKGROUND Nephrotic syndrome caused by minimal mesangial lupus nephritis is considered rare. Nephrotic syndrome can be caused by minimal mesangial lupus nephritis with diffuse epithelial foot-process effacement and lupus podocytopathy. CASE REPORT A 23-year-old Japanese woman diagnosed with mixed connective tissue disease was admitted because of weight gain and generalized edema for 2 weeks prior to admission. She had butterfly-shaped erythema on her cheeks, proteinuria, leukocytopenia with lymphocytopenia, and hypoalbuminemia. She was positive for antinuclear antibodies, and specific autoantibodies were only positive for the ribonucleoprotein (RNP) antigen. She was diagnosed with systemic lupus erythematosus. Renal biopsy showed minor glomerular abnormalities, and immunofluorescence revealed peripheral deposits of IgM and complement C3c. Electron microscopy revealed diffuse podocyte foot-process effacement of >80% of the capillary loop surfaces, with only a few subendothelial deposits. Consequently, we diagnosed minimal mesangial lupus nephritis with lupus podocytopathy. On hospital day 4, we administered 1000 mg/day of methylprednisolone for 3 days, followed by prednisolone 50 mg/day, but proteinuria persisted. On day 12, we administered tacrolimus (3 mg/day). Proteinuria improved and then disappeared on day 17. Prednisolone was gradually tapered and stopped after 3 years, although tacrolimus 3 mg/day was continued. No flare-up was observed 4 years after admission. CONCLUSIONS Tacrolimus showed good efficacy in this case of minimal mesangial lupus nephritis with lupus podocytopathy. Prospective and randomized controlled trials should be conducted to demonstrate the efficacy of tacrolimus for this indication.

Background: The anti-CD20 rituximab is often used in the treatment of children with steroid-resistant nephrotic syndrome or EBV-induced post-transplant lymphoproliferative disorder. This single-center series reports the use of rituximab as induction therapy in pediatric kidney transplantation., Methods: Four children who received rituximab as induction therapy for kidney transplantation since 2016 were retrospectively analyzed. Clinical and laboratory data were extracted from medical records., Results: The patients (2 boys and 2 girls) were aged from 6.1 to 11.9 years and were treated with rituximab on the day of the transplantation procedure; all the transplants came from deceased donors. In all patients, rituximab was used because of positive EBV viral loads before kidney transplantation. Viral loads remained undetectable for the first 6 months after the transplantation procedure and remained below the 4.5 log threshold thereafter. After a median follow-up of 2.3 years, none of the patients displayed rejection or de novo donor-specific antibodies; the glomerular filtration rate remained above 70 ml/min/1.73 m 2 . No post-transplant lymphoproliferative disorder was observed., Conclusion: The results suggest that rituximab can be used as induction therapy to prevent EBV replication and its complications in case of positive viral load prior to kidney transplantation., (© 2022 Wiley Periodicals LLC.)

Introduction: T4 nasopharyngeal carcinoma (NPC) with close proximity to critical organs at risk (OARs) is usually underdosed during radiotherapy in order to respect radiation constraints. N3 disease has high risk of distant metastasis. Induction chemotherapy (IC) provides advantages of sparing of OARs during subsequent chemoradiotherapy (CCRT) and early eradication of micrometastasis. However, factors predicting successes of IC in this patient group are not well-studied., Methods: 104 T4 or N3 NPC patients were retrospectively reviewed during 2007-2018. They were planned for IC followed by CCRT using intensity-modulated radiotherapy., Results: In the whole group, five-year failure-free survival (FFS), locoregional failure-free survival (LRFS), distant failure-free survival (DFFS) and overall survival (OS) were 40.9%, 45.7%, 46.9% and 53.6% respectively. Isolated marginal failure rate was 5% (4/80) among patients with primary tumours located close to critical OARs. Pre-IC gross tumour volume primary (GTVp) total volume > 110 cm 3 correlated with worse five-year LRFS (OR 6.37, P = 0.008), DFFS (OR 8.89, P = 0.003) and OS (OR 50.12, P < 0.001). In the T4 subgroup, IC improved D100% GTVp from 61.39 Gy to 64.71 Gy (P < 0.001) and V100% GTVp from 98.78% to 99.28% (P < 0.001)., Conclusion: Our study demonstrated improved dosimetric parameters and low isolated marginal failure rate. It supported the use of IC and CCRT for tumours located close to critical OARs. Further research is warranted to compare predictive roles of pre- and post-IC tumour volumes. For high-risk patients being defined by pre-IC volume or other prognostic models, treatment escalation should be considered., (© 2022 Royal Australian and New Zealand College of Radiologists.)

The effect of induction chemotherapy on liver function in patients with acute lymphoblastic leukemia is not well documented in Ethiopia. This study assessed hepatotoxicity in patients with acute lymphoblastic leukemia who were undergoing induction chemotherapy in Ethiopia. A 1-month cohort study was undertaken in forty patients with acute lymphoblastic leukemia, with measurements taken at the baseline, second, and fourth weeks. A Log 10 transformation was done because of the skewed distribution of liver function tests. Descriptive statistics such as mean and proportion were calculated. A mixed model ANOVA and Bonferroni post hoc test were computed. A p value < 0.05 was declared to determine statistical significance. Clinically significant hepatotoxicity was observed in 15% of patients. Mild liver injury occurred in 5% of patients. The mean of all liver function tests increased significantly from pre-induction to post-induction. ALT levels were significantly higher in patients who received blood transfusions, but not in those who did not. Regardless of other factors, ALP level in children is significantly higher than in adults, although total bilirubin in adults is higher than in children. A significant proportion of patients had hepatotoxicity. During chemotherapy induction, the mean of all liver function tests rose significantly, but this elevation of serum liver function tests may be transient. Chemotherapy drugs should be given without causing a significant alteration in serum liver function tests. Continuous monitoring of patients should be required., (© 2022.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically on the based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. We previously reported significantly improved failure-free survival using gemcitabine plus cisplatin induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma. Here, we present the final overall survival (OS) analysis. In this multicenter, randomized trial, patients were assigned to be treated with concurrent chemoradiotherapy alone (standard therapy, n = 238) or gemcitabine and cisplatin induction chemotherapy before concurrent chemoradiotherapy (n = 242). With a median follow-up of 69.8 months, the induction chemotherapy group had a significantly higher 5-year OS (87.9% v 78.8%, hazard ratio, 0.51 [95% CI 0.34 to 0.78]; P = .001) and a comparable risk of late toxicities (≥ grade 3, 11.3% v 11.4%). Notably, the depth of the tumor response to induction chemotherapy correlated significantly and positively with survival (complete response v partial response v stable/progressive disease, 5-year OS, 100% v 88.4% v 61.5%, P = .005). Besides, patients with a low pretreatment cell-free Epstein-Barr virus DNA load (< 4,000 copies/mL) might not benefit from induction chemotherapy (5-year OS, 90.6% v 91.4%, P = .77). In conclusion, induction chemotherapy before concurrent chemoradiotherapy improved OS significantly in patients with locally advanced nasopharyngeal carcinoma, without increasing the risk of late toxicities. Tumor response to induction chemotherapy and pretreatment cell-free Epstein-Barr virus DNA might be useful to guide individualized treatment.

Objective: To investigate the effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on the clinical efficacy and flow cytometry (FCM) minimal residual disease (MRD) of patients with acute myeloid leukemia (AML) after initial induction therapy in the real world., Methods: The clinical data of 44 AML patients who were diagnosed for the first time in the Department of Hematology, The Second Hospital of Anhui Medical University, and received the initial induction therapy were retrospectively analyzed. According to whether rhG-CSF was used after treatment, these patients were divided into control group and therapy group. The complete remission (CR) rate, duration of neutropenia, incidence of infection, duration of fever, cost of antibiotics drugs, length of hospital stay, FCM MRD, and relapse-free survival (RFS) time were compared between the two groups., Results: The CR rate in the control group was 60%, and 74% in the therapy group (P=0.3429). The duration of neutropenia was (21.28±7.91) days in the control group and (14.79±3.07) days in the therapy group (P=0.0016). The duration of fever was (12.80±7.31) days in the control group and (9.11±7.48) days in the therapy group (P=0.0136). While, there were no statistically significant differences between the two groups in the incidence of infection, cost of antibacterial drugs, length of hospital stay and RFS time (all P>0.05). In addition, it is particularly noteworthy that among the patients who finally obtained CR in the therapy group, 66% of them had myeloid precursor cells detected by peripheral blood FCM (accounting for 2.25%±0.99%) at the time of the first release of neutropenia, which was easy to be misdiagnosed as MRD positive., Conclusion: rhG-CSF not only don't affect the clinical remission rate after the initial induction treatment of AML, but also significantly shortens the time of duration of neutropenia and fever, however, it may affect the analysis of peripheral blood FCM MRD detection results when the neutropenia is released for the first time.

We present a 65-year-old woman who developed a diffuse pruritic papular eruption after receiving induction chemotherapy with daunorubicin and cytarabine for newly diagnosed acute myelomonocytic leukemia. The rash improved clinically with triamcinolone treatment and chemotherapy was allowed to continue. This case adds to the growing literature of transient acantholytic dermatosis development in the setting of anti-cancer therapy and emphasizes the importance of clinicopathologic correlation in cutaneous eruptions in cancer patients.

Introduction: In recent years, the prevalence of inflammatory bowel diseases has been increasing in Japan due to the westernization of lifestyles. Many patients have been reported to have extra-intestinal manifestations (EIMs) at least once. Skin lesions occur with a high degree of frequency among EIMs, with erythema nodosum (EN) and pyoderma gangrenosum (PG) the main complications. Cytapheresis is again attracting attention as a treatment with few side effects., Methods: We investigated the therapeutic effect of cytapheresis on ulcerative colitis (UC) and cutaneous EIMs. Between 2008 and 2021, 240 patients with active UC had induction therapy by cytapheresis at our hospital., Results: Remission and response rates were 50.0% and 67.5%, respectively. Apheresis was performed on seven patients with PG and five patients with EN with a good response. Serious adverse events were not observed., Conclusion: This retrospective assessment of efficacy showed that EN and PG responded favorably to cytapheresis., (© 2022 International Society for Apheresis and Japanese Society for Apheresis.)

Bleeding in patients with acute myeloid leukemia (AML) receiving intensive induction chemotherapy is multifactorial and contributes to early death. We sought to define the incidence and risk factors of grade 4 bleeding to support strategies for risk mitigation. Bleeding events were retrospectively assessed between day-14 and day +60 of induction treatment according to the World Health Organization (WHO) bleeding assessment scale, which includes grade 4 bleeding as fatal, life-threatening, retinal with visual impairment, or involving the central nervous system. Predictors were considered pretreatment or prior to grade 4 bleeding. Using multivariable competing-risk regression analysis with grade 4 bleeding as the primary outcome, we identified risk factors in the development cohort (n = 341), which were tested in an independent cohort (n = 143). Grade 4 bleeding occurred in 5.9% and 9.8% of patients in the development and validation cohort, respectively. Risk factors that were independently associated with grade 4 bleeding included baseline platelet count ≤40 × 109/L compared with >40 × 109/L, and baseline international normalized ratio of prothrombin time (PT-INR) >1.5 or 1.3 > 1.5 compared with ≤1.3. These variables were allocated points, which allowed for stratification of patients with low- and high-risk for grade 4 bleeding. Cumulative incidence of grade 4 bleeding at day+60 was significantly higher among patients with high- vs low-risk (development: 31 ± 7% vs 2 ± 1%; P < .001; validation: 25 ± 9% vs 7 ± 2%; P = .008). In both cohorts, high bleeding risk was associated with disseminated intravascular coagulation (DIC) and proliferative disease. We developed and validated a simple risk model for grade 4 bleeding, which enables the development of rational risk mitigation strategies to improve early mortality of intensive induction treatment., (© 2022 by The American Society of Hematology.

Purpose: Nasopharyngeal carcinoma (NPC) is a malignant tumor endangering human health. Gemcitabine or cisplatin chemotherapy has been regarded as effective treatment for patients with locoregionally advanced NPC. However, the effect of gemcitabine plus cisplatin concurrent chemoradiotherapy (CCRT) remained controversial among the studies. Therefore, we conducted this meta-analysis to assess the efficacy and safety of induction chemotherapy by gemcitabine and cisplatin (GP regimen) in patients with locoregionally advanced NPC., Methods: A systematic literature search was performed using PubMed, Web of Science, and Embase to evaluate the survival benefit and toxicity profiles of patients with locoregionally advanced NPC who were treated with CCRT. A random-effects model or a fixed-effects model was used to pool the data according to the heterogeneity among the included studies., Results: A total of five studies with 1286 patients met the inclusion criteria and were included in this meta-analysis. Pooled estimate showed that GP regimen was associated with significant improvements in OS (HR = 0.57, 95% CI 0.45, 0.73; P < 0.001), DFS (HR = 0.56, 95% CI 0.47, 0.66; P < 0.001), and DRFS (HR = 0.51, 95% CI 0.36, 0.73; P < 0.001), but not in LRFS (HR = 0.54, 95% CI 0.25, 1.19; P = 0.126) and ORR (RR = 1.30, 95% CI 0.54, 3.09; P = 0.556). Moreover, the incidence of adverse events of all grades (RR = 1.15, 95%CI 0.11, 1.38; P = 0.063) or grade 3-4 (RR = 0.96, 95%CI 0.57, 1.29; P = 0.385), was comparable between GP regimen and control treatments., Conclusion: Our meta-analysis indicated that the patients with locoregionally advanced NPC could benefit from the regimen of gemcitabine plus cisplatin induction chemotherapy., (© 2021.

Background: Acute respiratory events (ARE) occasionally occur during induction chemotherapy as a complication in patients with advanced neuroblastoma., Aims: The present study aimed to identify the predictive factors of ARE, defined as severe hypoxia, during initial induction chemotherapy in patients with newly diagnosed advanced neuroblastoma., Methods and Results: The medical records of 75 consecutive patients in whom stage III or IV neuroblastoma was newly diagnosed between January 2003 and December 2018 at two medical institutions were retrospectively reviewed. The outcome was ARE, which were assessed by measuring oxygen saturation between days 1 and 14 of initial induction chemotherapy. Severe hypoxia was defined as grade 3 or higher according to the Common Terminology Criteria for Adverse Events version 4 (CTCAE v4.0) or decreased oxygen saturation at rest (e.g., pulse oximeter <88% or PaO 2 ≤55 mmHg). Possible predictive factors on admission were first screened for using univariate analyses with P = .05, then models of the predictive power of the outcome were evaluated by generating receiver operating characteristic (ROC) curves. Eleven patients (14.7%) had the outcome, including three (4.0%) who required respiratory support in the intensive care unit. The area under the curve of the ROC for the predictive factors screened by univariate analyses was 0.84 (95% confidence interval [CI]: 0.73-0.95) for lactate dehydrogenase (LDH) and 0.90 (95% CI: 0.82-0.98) for the disseminated intravascular coagulation (DIC) score., Conclusion: The LDH value and DIC score on admission may be clinically useful predictors of ARE during initial induction chemotherapy in patients with advanced neuroblastoma., (© 2021 The Authors.

Importance: Induction chemotherapy added to concurrent chemoradiotherapy significantly improves survival for patients with locoregionally advanced nasopharyngeal carcinoma, but the optimal induction regimen remains unclear., Objective: To determine whether induction chemotherapy with paclitaxel, cisplatin, and capecitabine (TPC) improves survival vs cisplatin and fluorouracil (PF) prior to chemoradiotherapy for patients with stage IVA to IVB nasopharyngeal carcinoma., Design, Setting, and Participants: This randomized, open-label, phase 3 clinical trial recruited 238 patients at 4 hospitals in China from October 20, 2016, to August 29, 2019. Patients were 18 to 65 years of age with treatment-naive, nonkeratinizing stage IVA to IVB nasopharyngeal carcinoma and an Eastern Cooperative Oncology Group performance status of 0 to 1., Interventions: Patients were randomly assigned (1:1) to receive induction chemotherapy with two 21-day cycles of TPC (intravenous paclitaxel [150 mg/m2, day 1], intravenous cisplatin [60 mg/m2, day 1], and oral capecitabine [1000 mg/m2 orally twice daily, days 1-14]) or PF (intravenous cisplatin [100 mg/m2, day 1] and fluorouracil [800 mg/m2 daily, days 1-5]), followed by chemoradiotherapy., Main Outcomes and Measures: The primary end point was failure-free survival in the intention-to-treat population. Secondary end points included distant metastasis-free survival, locoregional relapse-free survival, overall survival, tumor response, and safety., Results: Overall, 238 eligible patients (187 men [78.6%]; median age, 45 years [range, 18-65 years]) were randomly assigned to receive TPC (n = 118) or PF (n = 120). The median follow-up duration was 48.4 months (IQR, 39.6-53.3 months). Failure-free survival at 3 years was 83.5% (95% CI, 77.0%-90.6%) in the TPC group and 68.9% (95% CI, 61.1%-77.8%) in the PF group (stratified hazard ratio [HR] for recurrence or death, 0.47; 95% CI, 0.28-0.79; P = .004). Induction with the TPC regimen resulted in a significant reduction in the risk of distant metastases (stratified HR, 0.49 [95% CI, 0.24-0.98]; P = .04) and locoregional recurrence (stratified HR, 0.40 [95% CI, 0.18-0.93]; P = .03) compared with the PF regimen. However, there was no effect on early overall survival (stratified HR, 0.45 [95% CI, 0.17-1.18]; P = .10). The incidences of grade 3 to 4 acute adverse events and late-onset toxicities were 57.6% (n = 68) and 13.6% (16 of 118), respectively, in the TPC group and 65.8% (n = 79) and 17.9% (21 of 117), respectively, in the PF group. One treatment-related death occurred in the PF group., Conclusions and Relevance: This randomized clinical trial found that induction chemotherapy with 2 cycles of TPC for patients with stage IVA to IVB nasopharyngeal carcinoma improved failure-free survival compared with 2 cycles of PF, with no increase in the toxicity profile., Trial Registration: ClinicalTrials.gov Identifier: NCT02940925.

Purpose: We hypothesized that diffusion-weighted magnetic resonance imaging (DWI)-guided dose-painting intensity modulated radiation therapy (DP-IMRT) is associated with improved local tumor control and survival in locoregionally advanced nasopharyngeal carcinoma (NPC). The purpose of this randomized study was to compare the efficacy and toxicity of DWI-guided DP-IMRT to conventional magnetic resonance imaging (MRI)-based IMRT in locoregional advanced NPC., Methods and Materials: A total of 260 patients with stage III-IVa NPC disease were randomly assigned in a 1:1 ratio to receive induction chemotherapy followed by chemoradiotherapy by DWI-guided DP-IMRT (group A, n = 130) or conventional MRI-based IMRT (group B, n = 130) in this prospective clinical trial. In group A, subvolume GTVnx- DWI (gross tumor volume of nasopharynx in DWI) was defined as the areas within the GTV nx (gross tumor volume of nasopharynx) with an apparent diffusion coefficient (ADC) below the mean ADC (ADC < mean) according to MRI before induction chemotherapy. The dose to GTVnx- DWI was escalated to 75.2 Gy/32 fx in patients with T1-2 disease and to 77.55 Gy/33 fx in those with T3-4 disease in 2.35 Gy per fraction. In group B, planning gross tumor volume of nasopharynx was irradiated at 70.4 to 72.6 Gy/32 to 33 fx in 2.2 Gy per fraction. This trial is registered with chictr.org.cn (ChiCTR1800015779)., Results: A total of 260 patients were included in the trial (130 patients in group A and 130 in group B). Complete response rates after chemoradiotherapy were 99.2% (129 of 130) and 93.8% (122 of 130) in groups A and B, respectively (P = .042). At a median follow-up of 25 months, DWI-guided DP-IMRT was associated with improved 2-year disease-free survival (DFS; 93.6% [95% confidence interval {CI}, 88.1%-99.1%] vs 87.5% [95% CI, 81.4%-93.6%], P = .015), local recurrence-free survival (100% [95% CI, not applicable {NA}] vs 91.3% [95% CI, 85.4%-97.2%]), locoregional recurrence-free survival (LRRFS; 95.8% [95% CI, NA] vs 91.3% [95% CI, 85.4%-97.2%]), distant metastasis-free survival (DMFS; 97.8% [95% CI, NA] vs 90.9% [95% CI, 85.8%-96.0%]), and overall survival (100% [95% CI, NA] vs 94.5% [95% CI, 89.2%-99.8%]). Zero and 3 patients had local-only recurrences in group A and B, respectively. The most common site of first failure in each arm was distant organ failure. No statistically significant differences in acute and late toxic effects were observed. Multivariate analyses showed that DP (DWI-guided DP-IMRT vs conventional MRI-based IMRT without DP) was associated with DFS, local recurrence-free survival, LRRFS, and distant metastasis-free survival. Epstein-Barr virus DNA level was associated with DFS and LRRFS., Conclusions: DWI-guided DP-IMRT plus chemotherapy is associated with a disease-free survival benefit compared with conventional MRI-based IMRT among patients with locoregionally advanced NPC without increasing acute toxic effects., (Copyright © 2022 Elsevier Inc.

Objective Peripherally inserted central catheters (PICCs) are widely used in patients with hematologic malignancies. However, the risks of PICC-related complications during chemotherapy for acute myeloid leukemia (AML) are not fully understood. Methods We conducted a retrospective review of 128 adult patients with AML who received induction therapy by way of PICC insertion between 2012 and 2019. Results The median duration of PICC insertion was 30 days. The incidence rate of catheter-related bloodstream infection (CRBSI) was 2.4% at 30 days, and women were more likely to suffer from CRBSI than men. Local reactions at the insertion site were observed in 56 patients; however, these events did not predict CRBSI. The incidence rates of catheter-related thrombosis (CRT) were 1.6% at 30 days. Obesity put patients at an increased risk for CRT. Unexpected PICC removal occurred in 59 patients, and women were at a higher risk of catheter removal than men. Conclusion Low PICC-related complication rates, possibly associated with high rates of catheter removal, were observed during intensive chemotherapy for AML. Women and obese patients require careful monitoring of their PICC. Procedures to achieve appropriate PICC removal without increasing the complication rate need to be considered.

Background: The objective of this study was to evaluate the efficacy and safety of induction chemotherapy (ICT), GOFL (gemcitabine, oxaliplatin plus fluorouracil (5-FU)/leucovorin) versus modified FOLFIRINOX (irinotecan, oxaliplatin plus 5-FU/leucovorin), followed by concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic adenocarcinoma (LAPC)., Methods: Chemo-naive patients with measurable LAPC were eligible and randomly assigned to receive biweekly ICT with either mFOLFIRINOX or GOFL for 3 months. Patients without systemic progression would have 5-FU- or gemcitabine-based CCRT (5040 cGy/28 fractions) and were then subjected to surgery or continuation of chemotherapy until treatment failure. The primary endpoint was 9-month progression-free survival (PFS) rate., Results: Between July 2013 and January 2019, 55 patients were enrolled. After ICT, 21 (77.8%) of 27 patients who received mFOLFIRINOX and 17 (60.7%) of 28 patients who received GOFL completed CCRT. Of them, one and five had per-protocol R0/R1 resection. On intent-to-treat analysis, the 9-month PFS rate, median PFS and overall survival in mFOLFIRINOX and GOFL arms were 30.5% versus 35.9%, 6.6 (95% confidence interval: 5.9-12.5) versus 7.6 months (3.9-12.3) and 19.6 (13.4-22.9) versus 17.9 months (13.4-23.9), respectively. Grade 3-4 neutropenia and diarrhoea during induction mFOLFIRINOX and GOFL were 37.0% versus 21.4% and 14.8% versus 3.6%, respectively., Conclusion: Induction GOFL and mFOLFIRINOX followed by CCRT provided similar clinical outcomes in LAPC patients., Gov Identifier: NCT01867892., (© 2021.
