PURPOSE Cisplatin plus gemcitabine is a standard regimen for first-line treatment of advanced non–small-cell lung cancer (NSCLC). Phase II studies of pemetrexed plus platinum compounds have also shown activity in this setting. PATIENTS AND METHODS This noninferiority, phase III, randomized study compared the overall survival between treatment arms using a fixed margin method (hazard ratio [HR] < 1.176) in 1,725 chemotherapy-naive patients with stage IIIB or IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 1. Patients received cisplatin 75 mg/m2 on day 1 and gemcitabine 1,250 mg/m2 on days 1 and 8 (n = 863) or cisplatin 75 mg/m2 and pemetrexed 500 mg/m2 on day 1 (n = 862) every 3 weeks for up to six cycles. RESULTS Overall survival for cisplatin/pemetrexed was noninferior to cisplatin/gemcitabine (median survival, 10.3 v 10.3 months, respectively; HR = 0.94; 95% CI, 0.84 to 1.05). Overall survival was statistically superior for cisplatin/pemetrexed versus cisplatin/gemcitabine in patients with adenocarcinoma (n = 847; 12.6 v 10.9 months, respectively) and large-cell carcinoma histology (n = 153; 10.4 v 6.7 months, respectively). In contrast, in patients with squamous cell histology, there was a significant improvement in survival with cisplatin/gemcitabine versus cisplatin/pemetrexed (n = 473; 10.8 v 9.4 months, respectively). For cisplatin/pemetrexed, rates of grade 3 or 4 neutropenia, anemia, and thrombocytopenia ( P ≤ .001); febrile neutropenia ( P = .002); and alopecia ( P < .001) were significantly lower, whereas grade 3 or 4 nausea ( P = .004) was more common. CONCLUSION In advanced NSCLC, cisplatin/pemetrexed provides similar efficacy with better tolerability and more convenient administration than cisplatin/gemcitabine. This is the first prospective phase III study in NSCLC to show survival differences based on histologic type.

Docetaxel and gemcitabine have different mechanisms of action, are well tolerated as monotherapies, and are affordable. This combination represents a good option for the second-line, bladder-preserving standard of care for non-muscle-invasive bladder cancer unresponsive to bacillus Calmette-Guérin.

Background: Metastatic pancreatic ductal adenocarcinoma (PDAC) is characterized by a poor survival rate, which can be improved by systemic treatment. Consensus on the most optimal first- and second-line palliative systemic treatment is lacking. The aim of this study was to describe the use of first- and second-line systemic treatment, overall survival (OS), and time to failure (TTF) of first- and second-line treatment in metastatic PDAC in a real-world setting. Patients and Methods: Patients with synchronous metastatic PDAC diagnosed between 2015 and 2018 who received systemic treatment were selected from the nationwide Netherlands Cancer Registry. OS and TTF were evaluated using Kaplan-Meier curves with log-rank test and multivariable Cox proportional hazard analyses. Results: The majority of 1,586 included patients received FOLFIRINOX (65%), followed by gemcitabine (18%), and gemcitabine + nab-paclitaxel (13%) in the first line. Median OS for first-line FOLFIRINOX, gemcitabine + nab-paclitaxel, and gemcitabine monotherapy was 6.6, 4.7, and 2.9 months, respectively. Compared to FOLFIRINOX, gemcitabine + nab-paclitaxel showed significantly inferior OS after adjustment for confounders (hazard ratio [HR], 1.20; 95% CI, 1.02–1.41), and gemcitabine monotherapy was independently associated with a shorter OS and TTF (HR, 1.98; 95% CI, 1.71–2.30 and HR, 2.31; 95% CI, 1.88–2.83, respectively). Of the 121 patients who received second-line systemic treatment, 33% received gemcitabine + nab-paclitaxel, followed by gemcitabine (31%) and FOLFIRINOX (10%). Conclusions: Based on population-based data in patients with metastatic PDAC, treatment predominantly consists of FOLFIRINOX in the first line and gemcitabine with or without nab-paclitaxel in the second line. FOLFIRINOX in the first line shows superior OS compared with gemcitabine with or without nab-paclitaxel.

Background: Despite recent advances in first-line chemotherapy for advanced pancreatic cancer, standard treatment after the failure of initial chemotherapy has not been established. Hence, we aimed to retrospectively analyze the clinical characteristics and outcomes of second-line chemotherapy in patients with advanced pancreatic cancer. Methods: We reviewed the clinical data of patients with advanced pancreatic cancer who underwent palliative chemotherapy at Kosin University Gospel Hospital between January 2013 and October 2020.Results: Among 366 patients with advanced pancreatic cancer who had received palliative chemotherapy, 104 (28.4%) underwent at least one cycle of second-line chemotherapy. The median age of the patients at the time of initiating second-line treatment was 62 years (interquartile range, 57–62 years), and 58.7% (61 patients) of them were male. The common second-line chemotherapy regimens were 5-fluorouracil (FU) plus leucovorin, irinotecan, and oxaliplatin (33 patients, 31.7%); gemcitabine/nab-paclitaxel (29, 27.9%), gemcitabine±erlotinib (13, 12.5%); and oxaliplatin and 5-FU/leucovorin (12, 11.5%). The median overall survival (OS) and progression-free survival were 6.4 months (95% confidence interval [CI], 4.5–8.6 months) and 4.5 months (95% CI, 2.7–6.3 months), respectively. In a multivariate analysis, poor performance status (PS) (hazard ratio [HR], 2.247; p=0.021), metastatic disease (HR, 2.745; p=0.011), and elevated carcinoembryonic antigen (CEA) levels (HR, 1.939; p=0.030) at the beginning of second-line chemotherapy were associated with poor OS.Conclusion: The survival outcome of second-line chemotherapy for advanced pancreatic cancer remains poor. However, PS, disease extent (locally advanced or metastatic), and CEA level may help determine patients who could benefit from second-line treatment.

A 61-year old male was referred to the Ophthalmology department because of decreased bilateral visual acuity. The patient had metastatic pancreatic adenocarcinoma and was being treated with gemcitabine+nab-paclitaxel. On examination, the patient presented best corrected visual acuities of 4/20 and 2/20 in the right and left eye, respectively. The optical coherence tomography revealed bilateral severe macular edema. Macular edema was considered secondary to nab-paclitaxel and the drug was discontinued. Three months after drug discontinuation, the patient presented best corrected visual acuities of 20/20 and 16/20 in the right and left eye, respectively, and normal fundoscopy. Macular edema is a very rare side effect of taxanes, and the etiopathology is still unknown. Edema is usually reversible upon discontinuation of the offending agent. Clinicians should be aware of this adverse effect of taxanes, and a high index of clinical suspicion is essential for diagnosis.Doente do sexo masculino, de 61 anos de idade, foi encaminhado para Oftalmologia por queixas de diminuição da acuidade visual bilateral. Tratava-se de um doente com um adenocarcinoma pancreático metastizado, sob tratamento com gemcitabina+nab-paclitaxel. Ao exame oftalmológico, o doente apresentava melhores acuidades visuais corrigidas de 4/20 e 2/20 do olho direito e esquerdo, respetivamente. A tomografia de coerência ótica revelou a presença de edema macular bilateral grave. O edema macular foi considerado secundário ao uso de nab-paclitaxel, pelo que o fármaco foi suspenso. Três meses após a suspensão do fármaco, o paciente apresentava acuidades visuais de 20/20 e 16/20 do olho direito e esquerdo, respetivamente, e uma fundoscopia normal. O edema macular é um efeito adverso muito raro dos taxanos e a sua etiopatologia ainda não se encontra totalmente esclarecida. O edema é habitualmente reversível após a suspensão do agente causador. Um elevado índice de suspeição é essencial para o diagnóstico desta condição.

Objectives The purpose of this study was to evaluate the cost-effectiveness of nab-paclitaxel and gemcitabine (GnP) compared with gemcitabine monotherapy (G) for patients with unresectable metastatic pancreatic cancer in Japan from the perspective of healthcare payer. Methods A partitioned survival analysis model was developed to predict costs and quality-adjusted life years (QALYs) for GnP and G. The time horizon of the model was set at 20 years. An annual discount rate of 2% for both costs and QALYs was applied. Data on overall survival and progression-free survival were derived from the Metastatic Pancreatic Adenocarcinoma Clinical Trial. Cost parameters were estimated from a Japanese medical claims database. The incremental cost-effectiveness ratio (ICER) of GnP compared with G was estimated. One-way sensitivity analysis was performed to assess the uncertainty in the parameter settings. In addition, scenario and probability sensitivity analyses were performed. Results The incremental cost and QALY of GnP compared with G were US$25 089 and 0.13 QALY, respectively. The ICER of GnP was estimated to be US$192 992 per QALY gained. Although the ICER was influenced by utility parameters and the survival curves, the ICERs remained higher than the willingness to pay (WTP) threshold of US$68 000 (JPY 7.5 million). The probability that GnP becomes cost-effective compared with G was estimated to be 29.2%. Conclusions Applying the WTP threshold of US$68 000 per QALY, GnP was not cost-effective for patients with unresectable metastatic pancreatic cancer in Japan from the perspective of healthcare payer. Further research is needed to obtain utility data from Japanese patients with pancreatic cancer.

Bladder cancers, and specifically urothelial carcinoma, have few effective treatment options, and tumors typically develop resistance against standard of care chemotherapies leading to significant mortality. The development of alternative therapies with increased selectivity and improved tolerability would significantly impact this patient population. Here, we investigate a novel colchicine derivative, CR42-24, with increased selectivity for the βIII tubulin subtype as a treatment for urothelial carcinoma. βIII tubulin is a promising target due to its low expression in healthy tissues and its clinical association with poor prognosis. This study demonstrated that CR42-24 is selectively cytotoxic to several cancer cell lines at low nanomolar IC50, with high activity in bladder cancer cell lines both in vitro and in vivo. CR42-24 monotherapy in an aggressive urothelial carcinoma xenograft model results in effective control when treated early. We observed significant ablation of large tumors and patient-derived xenografts at low doses with excellent tolerability. CR42-24 was highly synergistic in combination with the standard of care chemotherapies gemcitabine and cisplatin, further increasing its therapeutic potential as a novel treatment for urothelial carcinoma.

Gemcitabine is a commonly used antimetabolite that has been effective in a broad spectrum of tumors so far. The main grade three and four known toxicity of this drug is myelosuppression. Cardiac adverse events have been rarely reported and gemcitabine-induced Atrial-Fibrillation (AF) has been described in only five previous cases so far. Here we report the 6th case of gemcitabine- related AF. A 68-year-old man diagnosed with metastatic nasopharyngeal cancer was referred to our oncology department. He started first-line chemotherapy with gemcitabine and cisplatin. He presented poorly tolerated atrial fibrillation related to gemcitabine infusion that lasted for six days. The treatment was then withdrawn, and the patient received the best supportive care. We conclude that medical oncologists and cardiologists should be aware of such toxicities of gemc- itabine, especially in the elderly who seem to be at a higher risk of such adverse events and which may dictate discontinuation of the drug.

Purpose To evaluate treatment outcomes of de novo metastatic nasopharyngeal carcinoma (mNPC) patients receiving taxane/gemcitabine-containing chemotherapy followed by locoregional intensity-modulated radiotherapy (IMRT) and analyze potential prognostic factors. Methods A total of 118 patients between March 2008 and November 2018 were retrospectively analyzed. All the patients were treated with taxane/gemcitabine-containing systemic chemotherapy followed by definitive locoregional IMRT. Potential prognostic factors including baseline absolute lymphocyte count (ALC) and the subdivision of metastasis were analyzed. Results The median follow-up time for the whole group was 31.5 months (range 5–138 months). Of the 118 patients, 9 (7.6%) patients experienced local regional failure and 60 (50.8%) patients had progression of distant metastasis. At the time of the last follow-up, 61 (51.7%) patients were dead. The 5-year actuarial progression free survival (PFS), overall survival (OS),distant metastasis relapse free survival (DMFS) and local regional recurrence free survival (LRFS) were 34.2%, 44%, 41.1% and 82.6%, respectively. Baseline lymphocyte count ≥ 1600/μl prior to the treatment conferred better locoregional control (5y-LRFS 96% vs. 64.7%, p p = 0.023). The multivariate analysis showed that high lymphocyte count was the most relevant predictor of superior PFS (HR = 0.236, p p = 0.04). M subdivision was found as another independent prognostic factor for OS but not for PFS. Conclusion Taxane/gemcitabine-containing chemotherapy combined with IMRT represents an effective treatment modality for mNPC. Baseline ALC is an independent significant prognostic factor for PFS and OS.

Contains fulltext : 251531.pdf (Publisher’s version ) (Closed access) OBJECTIVE: To quantify the impact of individual complications on mortality, organ failure, hospital stay, and readmission after pancreatoduodenectomy. SUMMARY OF BACKGROUND DATA: An initial complication may provoke a sequence of adverse events potentially leading to mortality after pancreatoduodenectomy. This study was conducted to aid prioritization of quality improvement initiatives. METHODS: Data from consecutive patients undergoing pancreatoduodenectomy (2014-2017) were extracted from the Dutch Pancreatic Cancer Audit. Population attributable fractions (PAF) were calculated for the association of each complication (ie, postoperative pancreatic fistula, postpancreatectomy hemorrhage, bile leakage, delayed gastric emptying, wound infection, and pneumonia) with each unfavorable outcome [ie, in-hospital mortality, organ failure, prolonged hospital stay (>75th percentile), and unplanned readmission), whereas adjusting for confounders and other complications. The PAF represents the proportion of an outcome that could be prevented if a complication would be eliminated completely. RESULTS: Overall, 2620 patients were analyzed. In-hospital mortality occurred in 95 patients (3.6%), organ failure in 198 patients (7.6%), and readmission in 427 patients (16.2%). Postoperative pancreatic fistula and postpancreatectomy hemorrhage had the greatest independent impact on mortality [PAF 25.7% (95% CI 13.4-37.9) and 32.8% (21.9-43.8), respectively] and organ failure [PAF 21.8% (95% CI 12.9-30.6) and 22.1% (15.0-29.1), respectively]. Delayed gastric emptying had the greatest independent impact on prolonged hospital stay [PAF 27.6% (95% CI 23.5-31.8)]. The impact of individual complications on unplanned readmission was smaller than 11%. CONCLUSION: Interventions focusing on postoperative pancreatic fistula and postpancreatectomy hemorrhage may have the greatest impact on in-hospital mortality and organ failure. To prevent prolonged hospital stay, initiatives should in addition focus on delayed gastric emptying.

Introduction:We sought to demonstrate how an implementation science framework can be used to increase rates of postoperative intravesical chemotherapy with gemcitabine in patients with low-...

Background Lipusu is the first commercialized liposomal formulation of paclitaxel and has demonstrated promising efficacy against locally advanced lung squamous cell carcinoma (LSCC) in a small‐scale study. Here, we conducted a multicenter, randomized, phase 3 study to compare the efficacy and safety of cisplatin plus Lipusu (LP) versus cisplatin plus gemcitabine (GP) as first‐line treatment in locally advanced or metastatic LSCC. Methods Patients enrolled were aged between 18 to 75 years, had locally advanced (clinical stage IIIB, ineligible for concurrent chemoradiation or surgery) or metastatic (Stage IV) LSCC, had no previous systemic chemotherapy and at least one measurable lesion as per the Response Evaluation Criteria in Solid Tumors (version 1.1) before administration of the trial drug. The primary endpoint was progression‐free survival (PFS). The secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety profiles. To explore the possible predictive value of plasma cytokines for LP treatment, plasma samples were collected from the LP group at baseline and first efficacy evaluation time and were then subjected to analysis by 45‐Plex ProcartaPlex Panel 1 to detect the presence of 45 cytokines using the Luminex xMAP technology. The correlation between treatment outcomes and dynamic changes in the levels of cytokines were evaluated in preliminary analyses. Results The median duration of follow‐up was 15.4 months. 237 patients in the LP group and 253 patients in the GP group were included in the per protocol set (PPS). In the PPS, the median PFS was 5.2 months versus 5.5 months in the LP and GP group (hazard ratio [HR]: 1.03, P = 0.742) respectively. The median OS was 14.6 months versus 12.5 months in the LP and GP group (HR: 0.83, P = 0.215). The ORR (41.8% versus 45.9%, P = 0.412) and DCR (90.3% versus 88.1%, P = 0.443) were also similar between the LP and GP group. A significantly lower proportion of patients in the LP group experienced adverse events (AEs) leading to treatment interruptions (10.9% versus 26.4%, P < 0.001) or treatment termination (14.3% versus 23.1%, P = 0.011). The analysis of cytokine levels in the LP group showed that low baseline levels of 27 cytokines were associated with an increased ORR, and 15 cytokines were associated with improved PFS, with 14 cytokines, including TNF‐α, IFN‐γ, IL‐6, and IL‐8, demonstrating an overlapping trend. Conclusion The LP regimen demonstrated similar PFS, OS, ORR and DCR as the GP regimen for patients with locally advanced or metastatic LSCC but had more favorable toxicity profiles. The study also identified a spectrum of different cytokines that could be potentially associated with the clinical benefit in patients who received the LP regimen., Cisplatin plus Lipusu (LP) regimen has comparable efficacy and more favorable toxicity profiles compared with cisplatin plus gemcitabine (GP) regimen for patients with advanced LSCC. The study also demonstrated that LP had a significant impact on the levels of plasma cytokines and a spectrum of cytokines were associated with clinical benefit in patients who received LP. Thus, our results provided a new option for patients with advanced LSCC.

Objectives Berzosertib (formerly M6620, VX-970) is an intravenous, highly potent and selective, first-in-class ataxia telangiectasia and Rad3-related (ATR) protein kinase inhibitor. We assessed the safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of berzosertib plus gemcitabine in an expansion cohort of patients with advanced non–small cell lung cancer (NSCLC). The association of efficacy with TP53 status and other tumor markers was also explored. Materials and Methods Adult patients with advanced histologically confirmed NSCLC received berzosertib 210 mg/m2 (days 2 and 9) and gemcitabine 1000 mg/m2 (days 1 and 8) at the recommended phase 2 dose established in the dose escalation part of the study. Results Thirty-eight patients received at least one dose of study treatment. The most common treatment–emergent adverse events were fatigue (55.3%), anemia (52.6%), and nausea (39.5%). Gemcitabine had no apparent effect on the PK of berzosertib. The objective response rate (ORR) was 10.5% (4/38, 90% confidence interval [CI] 3.7–22.5). In the exploratory analysis, the ORR was 30.0% (3/10, CI: 9.0–61.0%) in patients with high loss of heterozygosity (LOH) and 11.0% (1/9, 90% CI: 1.0–43.0%) in patients with low LOH. The ORR was 33.0% (2/6, CI: 6.0–73.0%) in patients with high tumor mutational burden (TMB), 12.5% (2/16, 90% CI: 2.0–34.0%) in patients with intermediate TMB, and 0% (0/3, 90% CI: 0.0–53.6%) in patients with low TMB. Conclusions Berzosertib plus gemcitabine was well tolerated in patients with advanced, pre-treated NSCLC. Based on the observed clinical efficacy, future clinical trials should involve genomically selected patients.

INTRODUCTION: Neoadjuvant therapy may improve survival compared with upfront surgery in patients with resectable and borderline resectable pancreatic cancer, but high-quality evidence is lacking.METHODS: We systematically searched for randomised trials comparing neoadjuvant therapy with upfront surgery for resectable and borderline resectable pancreatic cancer published since database inception until December 2020. The primary outcome was overall survival (OS) by intention-to-treat with subgroup analyses for resectability status. Meta-analyses using a random-effects model were performed. Certainty of evidence was assessed using the GRADE approach.RESULTS: Seven trials with 938 patients were included. All trials included a neoadjuvant gemcitabine-based chemo(radio)therapy arm. None of the studies used adjuvant FOLFIRINOX. Neoadjuvant therapy improved OS (hazard ratio [HR] 0.66, 95% confidence interval [CI] 0.52-0.85; P = 0.001; I 2 = 46%) compared with upfront surgery. This represents an increase in median OS from 19 to 29 months. In the subgroup of resectable pancreatic cancer (i.e., venous contact ≤180°, no arterial contact), no statistically significant difference in OS was observed (HR 0.77, 95% CI 0.53-1.12; P = 0.18; I 2 = 20%). In the subgroup of borderline resectable pancreatic cancer (i.e. venous contact >180°, any arterial contact), neoadjuvant therapy improved OS (HR 0.61, 95% CI 0.44-0.85; P = 0.004; I 2 = 59%). The GRADE certainty of evidence was high for the outcome of OS. CONCLUSIONS: Neoadjuvant therapy improves OS compared with upfront surgery in patients with borderline resectable pancreatic cancer. More evidence is required on whether neoadjuvant therapy improves survival for patients with resectable pancreatic cancer.

Purpose: This study assessed the efficacy, safety, and pharmacokinetics of adavosertib in combination with four chemotherapy agents commonly used in patients with primary platinum-resistant ovarian cancer. Patients and Methods: Women with histologically or cytologically confirmed epithelial ovarian, fallopian tube, or peritoneal cancer with measurable disease were enrolled between January 2015 and January 2018 in this open-label, four-arm, multicenter, phase II study. Patients received adavosertib (oral capsules, 2 days on/5 days off or 3 days on/4 days off) in six cohorts from 175 mg once daily to 225 mg twice daily combined with gemcitabine, paclitaxel, carboplatin, or pegylated liposomal doxorubicin. The primary outcome measurement was overall response rate. Results: Three percent of patients (3/94) had confirmed complete response and 29% (27/94) had confirmed partial response. The response rate was highest with carboplatin plus weekly adavosertib, at 66.7%, with 100% disease control rate, and median progression-free survival of 12.0 months. The longest median duration of response was in the paclitaxel cohort (12.0 months). The most common grade ≥3 adverse events across all cohorts were neutropenia [45/94 (47.9%) patients], anemia [31/94 (33.0%)], thrombocytopenia [30/94 (31.9%)], and diarrhea and vomiting [10/94 (10.6%) each]. Conclusions: Adavosertib showed preliminary efficacy when combined with chemotherapy. The most promising treatment combination was adavosertib 225 mg twice daily on days 1–3, 8–10, and 15–17 plus carboplatin every 21 days. However, hematologic toxicity was more frequent than would be expected for carboplatin monotherapy, and the combination requires further study to optimize the dose, schedule, and supportive medications.

BACKGROUND: Metastatic pancreatic ductal adenocarcinoma (mPDAC) is highly lethal. Combination chemotherapy regimens improve overall survival (OS). Historically, only one third of mPDAC patients in Victoria received chemotherapy (1) . AIM: To describe current Australian chemotherapy utilisation and outcomes in patients with mPDAC using the multi-site PURPLE (Pancreatic cancer: Understanding Routine Practice and Lifting End Results) registry. METHODS: PURPLE collects longitudinal data on consecutive patients with pancreatic cancer seen since January 2016. Data was collated for patients with mPDAC from six Victorian sites, and analysed descriptively. RESULTS: Three-hundred-and-sixty-three patients with mPDAC were identified. Median age was 70 years (20-94). First line chemotherapy was administered in 195 patients (54%). Prevalent regimens included gemcitabine-nab-paclitaxel (71%), gemcitabine alone (10%) and FOLFIRINOX (6%). Sixty-two of 195 (32%) patients who received first line treatment have proceeded to second line chemotherapy. Chemotherapy treated patients were younger (69 versus 73 years, p

Background: Intrahepatic cholangiocarcinoma (iCCA) is the second most frequent liver cancer. The overall survival of iCCA and other biliary tract cancers (BTC) remains poor. Recently, the ABC-06 trial reported the superiority of FOLFOX vs clinical observation as a second-line treatment. Still, the survival benefit was less than expected. We hypothesized that the pattern of progression of iCCA can drive post-progression survival (PPS), similar to hepatocellular carcinoma. Methods: Multicentre retrospective evaluation of consecutive iCCA patients who progressed after frontline systemic treatment with gemcitabine as monotherapy or in combination with platinum. Radiological assessment of progression was evaluated according to RECIST 1.1. The progression pattern was divided according to the presence/absence of new extrahepatic lesions (NEH). Results: We included 206 patients from 5 centres. The median OS was 14.1months and its independent predictors (hazard ratio [HR], 95% confidence interval [CI]) were previous surgery 0.699 [0.509-0.961], performance status >2.445 [1.788-3.344], permanent first-line discontinuation 16.072 [5.102-50.633], registration of ascites 2.226 [1.448-3.420] or bilirubin >3mg/dl 3.004 [1.935-4.664] during the follow-up, and disease progression 2.523 [1.261-5.050]. The appearance of NEH independently predicted OS 2.18 [1.55-3.06] in patients with radiological progression. Amongst 138 patients eligible for second-line treatment, PPS was 16.8 and 5.9months in cases without and with NEH, respectively (P=.001). Progression owing to NEH lesions was an independent predictor of PPS 1.873 [1.333-2.662], together with performance status, time to progression to the frontline treatment, bilirubin >3mg/dl and ascites. Conclusions: PPS of iCCA is influenced by progression pattern, with important implications for second-line trial design and analysis.

The determination of the optimal induction chemotherapy (IC) regimen for patients with locally advanced nasopharyngeal carcinoma (NPC) remains controversial. Eligible trials included in this Bayesian network meta-analysis were judged by synthetically evaluating survival and safety outcomes. The analysis revealed that the combined IC regimen of gemcitabine plus cisplatin (GP) gained not only the most favorable overall survival (OS) benefit but also longer distant metastasis-free survival and manageable adverse events (AEs). Additionally, combination IC regimen of mitomycin, epirubicin, cisplatin, fluorouracil, and leucovorin had insufficient significant efficacy on complete response. Docetaxel combined with cisplatin and fluorouracil induction regimen provided the first exact probability of efficacy in term of local recurrence-free survival, ranking second in OS, but accompanied by the highest rates of grade 3 or above AEs. GP regimen appears to be currently the best choice of IC regimen for combined benefit of patients with locally advanced NPC.

Background : Cisplatin-based combination chemotherapy before surgery is the standard of care for muscle-invasive bladder cancer. However, the optimal chemotherapy modalities have not been precisely defined to date. Patients and Methods : In the VESPER trial, patients received after randomization either gemcitabine and cisplatin (GC, 4 cycles) or methotrexate, vinblastine, doxorubicin and cisplatin (dose dense [dd]-MVAC, 6 cycles). Creatinine clearance (CrCl) was calculated before each cycle according to the Cockroft and Gault formula. Definition criteria for local control after neoadjuvant chemotherapy included pathological complete response (ypT0N0), pathological downstaging ( Results : A total of 2,128 cycles of chemotherapy were delivered, including 2,120 (99.6%) with cisplatin. Full doses of cisplatin were given in 1866 (88%) cycles. Twenty-three (4.7%) patients had to stop chemotherapy (12 GC, 11 dd-MVAC) because of renal failure. No difference in CrCl median values was observed between the two regimens during the first four cycles. A mild decrease occurred thereafter in patients treated with two additional cycles of dd-MVAC. A minimum total dose of 270 mg/m2 for cisplatin was mandatory to optimize pathological complete responses. Conclusion : At least 4 cycles of cisplatin-based chemotherapy should be delivered before cystectomy. Increasing the number of cycles beyond 4 cycles does not lead to a clinically significant deterioration in renal function but without obvious gain on local control. MicroAbstractCGC : A deep analysis of data from a randomized trial of perioperative chemotherapy in muscle-invasive bladder cancer shows that a minimum number of 4 cycles is required to optimize the chances of pathological complete response at cystectomy. Increasing the number beyond 4 cycles does not lead to a clinically significant deterioration in renal function without any obvious gain on pathological complete response.

PURPOSE For unresectable gallbladder cancer (GBC), gemcitabine and platinum is standard combination; however, outcome is poor. We conducted this study to find feasibility of modified flourouracil, oxaliplatin, and irinotecan in this group. MATERIALS AND METHODS We conducted a prospective, phase II single-arm pilot study. Inclusion criteria were histologically proven GBC and Eastern Cooperative Oncology Group 0-1. Primary end points were overall response rates and overall survival. The following treatment was given: oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, and irinotecan 150 mg/m2, all once on day 1, fluorouracil 2,400 mg/m2 continuous intra-venous infusion over 46 hours repeated every 2 weeks, and maximum 12 doses, with primary granulocyte colony-stimulating factor prophylaxis. RESULTS Between February 2019 and July 2020, 29 patients with unresectable GBC were enrolled. The median age was 52 years, and 18 were females. The Eastern Cooperative Oncology Group was 0 in 4. Five had bilirubin > normal, and 15 each had high serum alkaline phosphatase and carbohydrate antigen 19-9. Twenty-five patients had stage IV disease, and remaining unresectable locally advanced disease. A median of 8.5 cycles was given, and 11 completed treatment. Nine stopped chemotherapy because of progression, and one because of toxicity, and treatment is ongoing in three. Twenty-two required dose reduction. A treatment delay of 1-2 weeks was seen in 25 patients. Best response was complete response 1, partial response 13 (overall response rate 48.2%), and stable disease 9. Four patients with metastatic disease underwent R0 resection. As on cutoff date, nine are surviving (three without disease). Eighteen died of PD, and in two, cause was unknown. There was no toxic death. The median overall survival and progression-free survival were 309 and 252 days, respectively. Twenty-three patients experienced grade III or IV toxicity, and common were diarrhea (13), vomiting (12), and anemia (7). CONCLUSION First-line modified flourouracil, oxaliplatin, and irinotecan is feasible in unresectable GBC with encouraging responses. Toxicities are higher but manageable. Higher response rates make this an option to explore in borderline resectable cases.

The clinical value and predictors of a favorable histological response to preoperative chemoradiotherapy (CRT) in pancreatic ductal adenocarcinoma (PDAC) remains undefined.To assess the significance and predictors of a favorable histological response to preoperative CRT in patients with localized PDAC.The study included 203 patients with localized PDAC undergoing curative-intent resection after CRT. The rate of R0 resection and overall survival (OS) and recurrence-free survival (RFS) were correlated with the grading of histological response to determine optimal stratification. Clinical factors associated with a significant histological response were evaluated using multivariate regression analysis.Among all patients, eight patients (3.9%) had a grade 4 (pCR); 40 (19.4%) had a grade 3 estimated rate of residual neoplastic cells10% (near-pCR); and 155 (76.7%) had a grade 1/2 limited response. The 48 patients with pCR/near-pCR achieved significantly higher R0 resection rate (100%) than those with grade 1/2 (80.0%). The 5-year OS and RFS rates were significantly higher in the patients with pCR/near-pCR (45.3% and 36.5%) than in those with grade 1/2 (27.1% and 18.5%). Gemcitabine plus S-1 based CRT, serum CA19-9 level after CRT83 U/mL, and interval from initial treatment to surgery ≥4.4 months were independent predictive factors for pCR/near-pCR.pCR or near-pCR to preoperative CRT contributed to achieving a high rate of R0 resection and improving survival for localized PDAC. The use of gemcitabine plus S-1 as a radiosensitizer, lower serum CA19-9 level after CRT, and longer preoperative treatment duration were significantly associated with pCR or near-pCR.

Background The prognosis of patients with borderline resectable pancreatic cancer with arterial contact (BRPC-A) is extremely poor, and effective preoperative treatment is indispensable. We evaluated the clinical efficacy and safety of neoadjuvant chemotherapy, including gemcitabine, nab-paclitaxel and S-1 (GAS), for patients with BRPC-A. Material and methods A multicentre, single-arm, phase II study was performed. Patients were administered 1000 mg/m2 gemcitabine on day 1, 125 mg/m2 nab-paclitaxel on day 1 and 60–100 mg/day S-1 on days 1–7 during a 14-day cycle. Patients were then assessed for resectability and response to treatment after six cycles. The primary end-points were 2-year overall survival (OS) rate and median OS time (trial registration: jRCTs061180045, UMIN000016630). Results Forty-seven patients with BRPC-A were eligible for the present study. Six courses of neoadjuvant GAS regimen were completed in all eligible patients. The rate of grade III/IV toxicities occurred in 14 (30%) patients during the neoadjuvant GAS regimen. The response and disease control rates were 43% and 96%, respectively. Forty-five (96%) patients received potentially curative pancreatectomy, whereas two did not owing to disease progression. R0 resection was performed in 40 (86%) of 47 eligible patients. Eleven (24%) patients experienced postoperative major complications (>grade III), including one mortality. The 2-year OS rate and median OS time among 47 eligible patients were 70.1% and 41.0 months, respectively. Conclusions The neoadjuvant GAS chemotherapy regimen for BRPC-A showed good efficacy with mild toxicity, resulting in a high R0 resection rate and prolonged survival in patients with BRPC-A.

BACKGROUND: Neoadjuvant chemoradiotherapy can provide downstaging and improve margin negativity for borderline resectable and resectable pancreatic adenocarcinoma [(B)RPC]. Little is known about the relative efficacy of capecitabine (CAPE)-based vs. gemcitabine (GEM)-based 3-week chemoradiation (3WCRT) with 36 Gy in 15 fractions. This study aimed to compare the odds of achieving surgical resection, time to progression (TTP), and overall survival (OS) of patients treated with 3WCRT with concurrent CAPE versus GEM. METHODS: A retrospective cohort study was conducted, examining medical records from a single center for patients with (B)RPC treated with 3WCRT between 1/2009–12/2020. Odd ratios (OR) of achieving surgical resection were estimated using logistic regression for univariable and multivariable analyses. Median TTP (mTTP) and median OS (mOS) were estimated using the Kaplan-Meier method. Cox proportional hazards analysis was conducted to estimate hazard ratios (HR) of progression and survival in univariable and multivariable analyses. RESULTS: Thirty-one patients were included in the analysis. Twenty-two (71%) patients were treated with CAPE, while 9 (29%) were treated with GEM. All patients in the GEM group were borderline resectable, vs. 18 (82%) patients in the CAPE group, P=0.30. Nineteen (86%) patients in the CAPE group were treated with neoadjuvant FOLFIRINOX, vs. 4 (44%) patients in the GEM group, P=0.03. The CAPE group had higher odds of achieving surgical resection [OR =9.33; 95% confidence interval (CI): 1.50–58.20]. Adjusting for covariates, the odds of achieving surgical resection were still statistically higher in the CAPE group vs. the GEM group (OR =25.34; 95% CI: 1.14–563.72). The CAPE group had superior mTTP compared to the GEM group (15.4 months, 95% CI: 4.9–71.1 vs. 4.0 months, 95% CI: 0.4–14.5; P=0.01), corresponding to a hazard ratio of 0.33 (95% CI: 0.14–0.81). Adjusting for covariates this effect persisted; the adjusted hazard ratio (AHR) for progression was 0.24 (95% CI: 0.08–0.77). Cox proportional hazards analysis also demonstrated that the CAPE group had superior OS compared to the GEM group in unadjusted (HR =0.13; 95% CI: 0.04–0.40) and adjusted models (HR =0.13, 95% CI: 0.03–0.52). CONCLUSIONS: For neoadjuvant 3WCRT, this hypothesis-generating study suggests concurrent CAPE may be a more effective radiosensitizer than GEM for patients with (B)RPC.

Background: There have not been any head-to-head prospective studies to compare the effects of different chemotherapy regimens as first-line treatments for unresectable pancreatic cancer (UPC). We aimed to compare the effectiveness of nab-paclitaxel plus gemcitabine, mFOLFIRINOX and gemcitabine plus oxaliplatin (GEMOX) as first-line treatments by using real-world data from Chinese patients. Methods: We retrospectively included patients with UPC treated with nab-paclitaxel plus gemcitabine, mFOLFIRINOX or GEMOX as a first-line treatment at Sun Yat-sen University Cancer Center. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR) were assessed. Results: A total of 117 patients were administered nab-paclitaxel plus gemcitabine (n = 62), mFOLFIRINOX (n = 30) or GEMOX (n = 25) as first-line chemotherapy. The median OS was 11.1, 10.1 and 10.2 months (p = 0.75) in the nab-paclitaxel plus gemcitabine, mFOLFIRINOX and GEMOX, respectively. The ORR was similar among the three groups (24%, 23% and 32%, p = 0.76) and the DCR was higher in the nab-paclitaxel-gemcitabine group (82%) than the other two groups (60% and 64%, p = 0.04). The most common adverse events of grade 3 or 4 were neutropenia (32%, 28% and 5%), peripheral neuropathy (13%, 16% and 0) and fatigue (9%, 16% and 5%). Febrile neutropenia occurred in 2%, 4% and 5% of the patients in the three groups. Conclusion: In the first line treatment of UPC, our results suggest that nab-paclitaxel plus gemcitabine was associated with a higher DCR than mFOLFIRINOX or GEMOX, while all groups demonstrated similar OS, PFS and ORR.

A 57-year-old woman with a sudden-onset seizure was hospitalized. Brain magnetic resonance imaging findings led to a suspicion of leptomeningeal carcinomatosis (LMC) without a brain parenchymal tumor, and abdominal computed tomography showed a tumor in the pancreatic tail. Endoscopic ultrasonography-guided fine needle aspiration of the pancreatic mass revealed adenocarcinoma. Therefore, LMC from pancreatic ductal adenocarcinoma was strongly suspected. She received three courses of nab-paclitaxel plus gemcitabine and whole-brain radiation. Shortly thereafter, she developed a severe consciousness impediment and died. A pathological autopsy showed adenocarcinoma in a wide area of the leptomeninges.

The use of sequential intravesical instillation of gemcitabine and docetaxel in the management of bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer should not be recommended as a second-line treatment. First, technical issues are a barrier to broad adoption of this strategy. Second, the low level of evidence supporting this treatment remains weak and needs proper assessment.

Early-stage natural killer/T-cell lymphoma (NK/TCL) patients usually receive a combination of chemotherapy and radiotherapy, but the optimal treatment approach has not yet been established. This study aimed to investigate the efficacy and safety profile of a novel chemotherapy regimen and sandwiched radiotherapy in early-stage NK/TCL. Patients with newly diagnosed stage IE/IIE disease were eligible. Patients were initially treated with two courses of the GELAD regimen (gemcitabine 1·0 g/m2 day 1, etoposide 60 mg/m2 days 1-3, pegaspargase 2000 units/m2 day 4, and dexamethasone 40 mg days 1-4), followed by intensity-modulated radiotherapy (IMRT; 50-56 Gy in 25-28 fractions) and two additional courses of GELAD chemotherapy. A total of 52 patients were enrolled. The overall response rate and complete response rate per Lugano 2014 criteria were 94·2% and 92·3% respectively. With a median follow-up of 32 months, the estimated four-year overall survival rate and progression-free survival rate were 94·2% [95% confidence interval (CI), 83·2% to 93·1%] and 90·4% (95% CI, 78·4% to 95·9%) respectively. The most common adverse events were related to pegaspargase. Haematological toxicities were mild, with grade 3/4 neutropenia in 15·4% of patients. Our study provides a new approach with high activity and improved safety for the treatment of early-stage NK/TCL patients. This study was registered at www.clinicaltrials.gov as NCT02733458.

PURPOSE This phase III, multicenter, randomized, open-label study investigated the efficacy and safety of nivolumab versus chemotherapy (gemcitabine [GEM] or pegylated liposomal doxorubicin [PLD]) in patients with platinum-resistant ovarian cancer. MATERIALS AND METHODS Eligible patients had platinum-resistant epithelial ovarian cancer, received ≤ 1 regimen after diagnosis of resistance, and had an Eastern Cooperative Oncology Group performance score of ≤ 1. Patients were randomly assigned 1:1 to nivolumab (240 mg once every 2 weeks [as one cycle]) or chemotherapy (GEM 1000 mg/m2 for 30 minutes [once on days 1, 8, and 15] followed by a week's rest [as one cycle], or PLD 50 mg/m2 once every 4 weeks [as one cycle]). The primary outcome was overall survival (OS). Secondary outcomes included progression-free survival (PFS), overall response rate, duration of response, and safety. RESULTS Patients (n = 316) were randomly assigned to nivolumab (n = 157) or GEM or PLD (n = 159) between October 2015 and December 2017. Median OS was 10.1 (95% CI, 8.3 to 14.1) and 12.1 (95% CI, 9.3 to 15.3) months with nivolumab and GEM or PLD, respectively (hazard ratio, 1.0; 95% CI, 0.8 to 1.3; P = .808). Median PFS was 2.0 (95% CI, 1.9 to 2.2) and 3.8 (95% CI, 3.6 to 4.2) months with nivolumab and GEM or PLD, respectively (hazard ratio, 1.5; 95% CI, 1.2 to 1.9; P = .002). There was no statistical difference in overall response rate between groups (7.6% v 13.2%; odds ratio, 0.6; 95% CI, 0.2 to 1.3; P = .191). Median duration of response was numerically longer with nivolumab than GEM or PLD (18.7 v 7.4 months). Fewer treatment-related adverse events were observed with nivolumab versus GEM or PLD (61.5% v 98.1%), with no additional or new safety risks. CONCLUSION Although well-tolerated, nivolumab did not improve OS and showed worse PFS compared with GEM or PLD in patients with platinum-resistant ovarian cancer.

Introduction Pancreatic cancer is a devastating disease with a high relapse rate, even in resectable pancreatic cancer. This study aimed to identify the prognostic significance and therapeutic chance of the metabolic subtypes for resectable pancreatic cancer. Methods We obtained transcriptomic data from the TCGA-PAAD cohort via the The Cancer Genome Atlas (TCGA) data portal (n = 182). After integrative analysis of transcriptomic data in the discovery cohort, immunohistochemical (IHC) staining was performed in the independent cohort to validate the molecule of interest. Experimental testing for the molecule of interest was performed using pancreatic cancer cell lines, including AsPC1, BxPC3, MIA PaCa-2, and PANC-1 in vitro. Results Two subtypes showing distinct gene expression patterns in the TCGA-PAAD dataset were identified. The active glucose metabolism subtype showed significantly lower survival regarding cancer relapse after surgical resection. The genes SLC2A1 (GLUT1) and SLC16A3 (MCT4) were highly enriched in the active metabolism subtype. The validation cohort showed high IHC staining intensity for MCT4 and a significantly high relapse rate (p = 0.01). Several molecular pathways associated with aggressive tumor biology regarding cell cycle, Myc, and mTOR downstream signaling were highly enriched in the high glucose uptake subtype as well as distinct response for immunotherapy. MCT4 inhibition suppressed pancreatic cancer cell lines in vitro and showed a synergetic effect with gemcitabine treatment. Conclusions MCT4 was identified from integrative analysis as a potential therapeutic target in resectable pancreatic cancer. The precision strategy for resectable pancreatic cancer should be validated in a clinical setting with a prospective study design.

This prespecified subanalysis of the global, randomized controlled phase III KEYNOTE‐024 study of pembrolizumab vs chemotherapy in previously untreated metastatic non‐small‐cell lung cancer without EGFR/ALK alterations and a programmed death ligand 1 (PD‐L1) tumor proportion score of 50% or higher evaluated clinical outcomes among patients enrolled in Japan. Treatment consisted of pembrolizumab 200 mg every 3 weeks (35 cycles) or platinum‐based chemotherapy (four to six cycles). The primary end‐point was progression‐free survival; secondary end‐points included overall survival and safety. Of 305 patients randomized in KEYNOTE‐024 overall, 40 patients were enrolled in Japan (all received treatment: pembrolizumab, n = 21; chemotherapy, n = 19). Median progression‐free survival was 41.4 (95% confidence interval [CI], 4.2‐42.5) months with pembrolizumab and 4.1 (95% CI, 2.8‐8.3) months with chemotherapy (hazard ratio [HR], 0.27 [95% CI, 0.11‐0.65]; one‐sided, nominal P = .001). Median overall survival was not reached (NR) (95% CI, 22.9‒NR) and 21.5 (95% CI, 5.2‐35.0) months, respectively (HR, 0.39 [95% CI, 0.17‐0.91]; one‐sided, nominal P = .012). Treatment‐related adverse events occurred in 21/21 (100%) pembrolizumab‐treated and 18/19 (95%) chemotherapy‐treated patients; eight patients (38%) and nine patients (47%), respectively, had grade 3‐5 events. Immune‐mediated adverse events and infusion reactions occurred in 11 pembrolizumab‐treated patients (52%) and four chemotherapy‐treated patients (21%), respectively; four patients (19%) and one patient (5%), respectively, had grade 3‐5 events. Consistent with results from KEYNOTE‐024 overall, first‐line pembrolizumab improved progression‐free survival and overall survival vs chemotherapy with manageable safety among Japanese patients with metastatic non‐small‐cell lung cancer without EGFR/ALK alterations and a PD‐L1 tumor proportion score of 50% or higher. The trial is registered with Clinicaltrials.gov: NCT02142738., This prespecified subanalysis of the global, randomized controlled phase III KEYNOTE‐024 study of pembrolizumab vs chemotherapy in previously untreated metastatic non‐small‐cell lung cancer without EGFR/ALK alterations and a PD‐L1 tumor proportion score of 50% or higher evaluated clinical outcomes among patients enrolled in Japan. Consistent with results from KEYNOTE‐024 overall, first‐line pembrolizumab improved progression‐free survival and overall survival vs chemotherapy with manageable safety among 40 Japanese patients in the study.

Background: Gemcitabine together with nab-paclitaxel (GnP) has been shown to improve outcomes in patients with pancreatic ductal adenocarcinoma (PDAC). However, the predictive markers for treatment effects remain unclear. This study aimed to identify early prognostic factors in patients with PDAC receiving GnP. Patients and Methods: We analyzed 113 patients who received GnP for PDAC and evaluated the relationship between clinical factors and outcomes. Results: The median survival time (MST) was 1.2 years. In multivariate analysis, baseline carbohydrate antigen 19-9 (CA19-9) ≥747 U/ml [hazard ratio (HR)=1.9], baseline controlling nutrition status (CONUT) score ≥5 (HR=3.7) and changing rate of CA19-9 after two GnP cycles ≥0.69 (HR=3.7) were independent risk factors for poor prognosis. When examining outcomes according to pre-chemotherapeutic measurable factors (baseline CA19-9 and CONUT), the MSTs of patients with pre-chemotherapeutic zero risk factors (pre-low-risk group, n=63) and one or more risk factors (pre-high-risk group, n=50) were 1.7 and 0.65 years (p

Objective This study aims to evaluate the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) following the simultaneous placement of self-expandable metallic stent (SEMS) and iodine-125 (125I) seed strands for the management of advanced cholangiocarcinoma (CCA) patients presenting with malignant obstructive jaundice (MOJ). Methods Data from 74 patients with MOJ caused by advanced CCA treated with stent placement with 125I seed strands with or without HAIC between November 2015 and October 2020 were analysed retrospectively. Eighteen patients received 5 sessions of HAIC after SEMS placement with 125I seed strands (HAIC group), and 56 patients only underwent SEMS placement with 125I seed strands and served as controls (control group). HAIC consisted of infusions of gemcitabine (600-1000 mg/m2 given over 30 min) followed by oxaliplatin (60-100 mg/m2 given over 2 h), with an interval of 4 weeks. Propensity score matching (PSM) analysis was used to adjust for differences in the baseline characteristics of the groups (including age, total bilirubin, and serum alanine aminotransferase level). Overall survival (OS), stent patency, and adverse events were compared between the two groups. Results OS and stent patency were significantly better in patients in the HAIC group than in those in the control group (median survival time: before PSM, 362 vs. 185 days, p = 0.005; after PSM, 357 vs. 183 days, p = 0.012; median duration of stent patency: before PSM, 294 vs. 156 days, p = 0.001; after PSM, 287 vs. 183 days, p = 0.039). All adverse reactions were controllable by temporary symptomatic treatment. Serious complications and treatment-related deaths were not observed. Conclusion Our preliminary study showed that HAIC following SEMS placement with 125I seed strands is effective and safe for the management of advanced CCA patients presenting with MOJ and could improve stent patency and patient survival.

Purpose: the present study aims to investigate the function of miR-199 on gemcitabine (GEM)-resistance in pancreatic cancer, as well as the underlying mechanism. Methods: the GEM-resistant SW1990 cell line (SW1990/SZ) was established. The CCK-8 assay was used to detect the cell viability. The self-renewal of SW1990/SZ cells was evaluated by sphere formation and the colony formation assay. The apoptosis was detected by flow cytometry and the migration ability was measured by the transwell assay. The dual-luciferase gene reporter assay was utilized to confirm the binding between miR-199 and Snail. The expression level of CD44, ALDH1, Nanog, E-cadherin, Vimentin, β-catenin, and Snail was determined by the Western blotting assay. Results: the cell sphere formation rate, number of spheres, and expression level of CD44, ALDH1, and Nanog in GEM-treated SW1990/SZ cells were significantly suppressed by miR-199, accompanied by declined proliferation ability, an increased apoptotic rate, inhibited migration ability, and suppressed EMT progression. The binding site between miR-199 and 3′-UTR of Snail was predicted and confirmed. The inhibitory effect of miR-199 on self-renewal of SW1990/GZ cells and the faciliating property of miR-199 on the inhibitory effect of GEM against the proliferation ability, migration ability, and EMT progression were abolished by overexpressing Snail. Conclusion: MiR-199 reversed the resistance to GEM in pancreatic cancer by suppressing stemness through regulating the EMT.

Background Many real‐world studies of patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) are restricted to single centers, limiting the generalizability of their insights. This study aimed to identify important population‐based predictors for survival in patients diagnosed with mPDAC in a broader setting. Methods Data between 1 January 2017 and 31 December 2019 were extracted from the Flatiron Health EHR database. Treatment‐specific predictive models were generated for patients treated with first‐line gemcitabine+nab­paclitaxel (GNP), FOLFIRINOX, gemcitabine monotherapy (gem‐mono), and second‐line liposomal irinotecan‐based regimens. The holdout method was used for cross‐validation. Age at diagnosis, sex, BMI, smoking status, and ECOG performance score were included in all models with additional demographic, clinical characteristics, and hematological function assessed for inclusion. Results Of the 3625 patients, 43% received GNP, 26% received FOLFIRINOX, 7% received gem‐mono, and 23% received other regimens; 40% (n = 1448) advanced to the second line. Among all first‐line patients, the following were included in the final model: prior surgery, white blood cell (WBC) counts, serum albumin (SA), liver function tests (LFTs), serum bilirubin, serum carbohydrate antigen 19–9, and ascites. Models for patients receiving specific therapies differed from the overall model, GNP (ascites removed), FOLFIRINOX (stage at initial diagnosis added), and gem‐mono (LFTs omitted). Alkaline phosphatase (ALP), SA, and WBC counts were important predictors of survival among patients treated with second‐line liposomal irinotecan. Across all regimens, the strongest predictors of survival were ECOG score, SA, and ALP. Conclusions In this real‐world study of patients with mPDAC, important population prognostic factors of survival were identified in a large cohort of patients receiving systemic treatment., This retrospective observational analysis of US patient‐level electronic health record data identified a sample of 3625 patients who initiated first‐line systemic therapy for metastatic pancreatic ductal adenocarcinoma from 2017 to 2019. Important population prognostic factors of survival were identified that applied across all regimens including performance status, serum albumin, and alkaline phosphatase levels. Additional patient characteristics were identified as prognostic factors of survival in the context of specific therapies.

Summary Background The prognosis of patients with advanced biliary tract cancer who have progressed on gemcitabine plus cisplatin is dismal. We aimed to investigate the efficacy and safety of second-line liposomal irinotecan plus fluorouracil and leucovorin in patients with metastatic biliary tract cancer that has progressed on gemcitabine plus cisplatin. Methods This multicentre, open-label, randomised, phase 2b (NIFTY) study was done at five academic institutions in South Korea and included patients aged 19 years or older with histologically or cytologically confirmed metastatic biliary tract cancer that had progressed on first-line gemcitabine plus cisplatin and an Eastern Cooperative Oncology Group performance status of 0 or 1. By use of an interactive web-based response system integrated with an electronic data capture system, patients were randomly assigned (1:1) using permuted blocks (block size 4) to receive either intravenous liposomal irinotecan (70 mg/m2 for 90 min) plus intravenous leucovorin (400 mg/m2 for 30 min) and intravenous fluorouracil (2400 mg/m2 for 46 h) every 2 weeks or leucovorin and fluorouracil only every 2 weeks, and were stratified by primary tumour site, previous surgery with curative intent, and participating centre. Study treatment was continued until the patient had disease progression or unacceptable toxicities, or withdrew consent. The primary endpoint was blinded independent central review (BICR)-assessed progression-free survival. The primary endpoint and safety were assessed in the full analysis set and the safety analysis set, respectively, both of which comprised all randomly assigned patients who received at least one dose of the study treatment. This trial is registered with ClinicalTrials.gov , NCT03524508 , and enrolment is complete. Findings Between Sept 5, 2018, and Feb 18, 2020, 193 patients were screened for eligibility, of whom 174 (88 in the liposomal irinotecan plus fluorouracil and leucovorin group and 86 in the fluorouracil plus leucovorin group) were enrolled and included in the full analysis and safety analysis sets. At a median follow-up of 11·8 months (IQR 7·7–18·7), the median BICR-assessed progression-free survival was significantly longer in the liposomal irinotecan plus fluorouracil and leucovorin group (7·1 months, 95% CI 3·6–8·8) than in the fluorouracil and leucovorin group (1·4 months, 1·2–1·5; hazard ratio 0·56, 95% CI 0·39–0·81; p=0·0019). The most common grade 3–4 adverse events were neutropenia (21 [24%] of 88 in the liposomal irinotecan plus fluorouracil and leucovorin group vs one [1%] of 86 in the fluorouracil and leucovorin group) and fatigue or asthenia (11 [13%] vs three [3%]). Serious adverse events occurred in 37 (42%) patients receiving liposomal irinotecan plus fluorouracil and leucovorin and 21 (24%) patients receiving fluorouracil and leucovorin. There were no treatment-related deaths. Interpretation Adding liposomal irinotecan to fluorouracil and leucovorin significantly improved BICR-assessed progression-free survival in patients with advanced biliary tract cancer. Liposomal irinotecan plus fluorouracil and leucovorin could be considered a standard-of-care second-line therapy for advanced biliary tract cancer.

Pancreatic ductal adenocarcinoma (PDAC) is a solid malignant tumor with a very low operative rate and a poor patient prognosis. Therefore, gemcitabine (GEM)-based chemotherapy remains one of the most important treatment choices for PDAC. However, the efficacy of GEM monotherapy or GEM combination chemotherapy in improving the survival of patients with advanced PDAC is very limited, primarily due to GEM resistance. The mechanism of GEM resistance is complex and unclear. An extensive and dense fibrous matrix in the tumor microenvironment (TME) is an important feature of PDAC. Increasing evidence indicates that this fibrotic TME not only actively participates in the growth and spread of PDAC but also contributes to the induction of GEM resistance. Metabolic remodeling reduces GEM transport and synthesis in PDAC. This review focuses on the main cellular and molecular mechanisms underlying the involvement of the extracellular matrix (ECM), immune cells, and metabolic remodeling in the induction of GEM resistance; highlights the prospect of targeting the TME as an essential strategy to overcome GEM resistance; and provides new precise interventions for chemotherapy sensitization and improving the overall prognosis of patients with PDAC.

We investigated the efficacy and safety of further bevacizumab therapy in patients with platinum‐resistant ovarian cancer whose disease had progressed after bevacizumab plus chemotherapy. In this multicenter, open‐label, phase II trial (JGOG3023), patients were randomized 1:1 to a single‐agent chemotherapy alone (either pegylated liposomal doxorubicin [40 or 50 mg/m2 administered intravenously], topotecan [1.25 mg/m2 intravenously], paclitaxel [80 mg/m2 intravenously], or gemcitabine [1000 mg/m2 intravenously]) or single‐agent chemotherapy + bevacizumab (15 mg/m2 intravenously). The primary endpoint was investigator‐assessed progression‐free survival (PFS) according to RECIST version 1.1. Secondary endpoints were overall survival (OS), objective response rate (ORR), and response rate according to Gynecological Cancer Intergroup cancer antigen 125 criteria. In total, 103 patients were allocated to chemotherapy (n = 51) or chemotherapy + bevacizumab (n = 52). Median investigator‐assessed PFS was 3.1 and 4.0 mo in each group, respectively (hazard ratio [HR] = 0.54, 95% confidence interval [CI]: 0.32‐0.90, P = .0082). Median OS was 11.3 and 15.3 mo in each group, respectively (HR = 0.67, 95% CI: 0.38‐1.17, P = .1556). Respective ORRs were 13.7% and 25.0% (P = .0599) and response rates were 16.7% and 21.4% (P = .8273). The incidence of grade ≥3 treatment‐related AEs was 42.0% in the chemotherapy group and 54.9% in the chemotherapy + bevacizumab group; AEs were well tolerated, with only 2 and 12 events leading to discontinuation of therapy, respectively. Bevacizumab was effective beyond progressive disease and AEs were manageable. The observed improvement in PFS requires further verification., We evaluated chemotherapy ± bevacizumab for platinum‐resistant recurrent ovarian cancer previously treated with bevacizumab. The results of this phase II study demonstrate the efficacy and manageable toxicity of continuing bevacizumab beyond progressive disease in patients with platinum‐resistant recurrent ovarian cancer previously treated with bevacizumab for front‐line or platinum‐sensitive recurrent ovarian cancer.

Background The efficacy of modified FOLFIRINOX (mFOLFIRINOX) as a second-line chemotherapy treatment for metastatic pancreatic adenocarcinoma (mPAC), remains unclear. This multi-center randomised phase III trial aimed to elucidate the efficacy of mFOLFIRINOX as a second-line chemotherapy treatment for mPAC patients with good performance status. Patients and methods Eighty mPAC patients (age, 19–75 years) refractory to first-line gemcitabine-based chemotherapy were randomly selected to receive mFOLFIRINOX or S-1. mFOLFIRINOX comprised oxaliplatin (65 mg/m2), irinotecan (135 mg/m2), and leucovorin (400 mg/m2) on day 1 and continuous 5-FU infusion (1000 mg/m2) over 24 h on days 1–2 every 2 weeks. S-1 comprised body surface area-dependent oral S-1, divided into two doses per day on days 1–28 every 6 weeks. Results Overall survival was the primary endpoint. The objective response and disease control rates were higher in the mFOLFIRINOX than in the S-1 group (15% versus 2%; p = .04 and 67% versus 37%; p = .007). The median progression-free survival rates were 5.2 and 2.2 months in the mFOLFIRINOX and S-1 groups, respectively (adjusted hazard ratio [HR]: .4; 95% confidence interval [CI]: .2-.6; p Conclusion Administration of mFOLFIRINOX as a second-line chemotherapy treatment for mPAC patients refractory to gemcitabine-based chemotherapy resulted in increased survival rates than S-1 treatment alone.

BACKGROUND This study aimed to investigate the response to platinum-based chemotherapy rechallenge in patients with pembrolizumab-refractory urothelial carcinoma. PATIENTS AND METHODS We retrospectively reviewed 14 patients with pembrolizumab-refractory urothelial carcinoma. Each patient received a regimen that they had not previously received (paclitaxel plus carboplatin in 10, gemcitabine plus docetaxel and carboplatin in four). Tumor response and adverse events were assessed. We evaluated overall survival from the chemotherapy rechallenge start date until death. RESULTS The median overall survival was 11.2 months. The disease-control rate was 85.7%. Partial responses occurred in the metastases in lymph nodes in three (37.5%) patients, lung in one (25%), peritoneal in three (75%), and liver in three (100%). Neutropenia of grade ≥3 occurred in 13 (92.9%) patients. CONCLUSION The activity of platinum-based chemotherapy rechallenge after pembrolizumab was maintained. Neutropenia was observed in most patients.

A 69-year-old man with refractory lung adenocarcinoma was treated with gemcitabine and vinorelbine. Dyspnea and hypertension developed after the 17th cycle of chemotherapy. Laboratory findings revealed intravascular hemolysis and renal dysfunction. Thrombotic microangiopathy (TMA) was confirmed by renal biopsy. Antihypertensive and steroid therapies were ineffective. After plasmapheresis, intravascular hemolysis and renal dysfunction gradually improved. However, the disease progressed, and he died 6 months after TMA diagnosis. Autopsy revealed similar pathological findings to those of the renal biopsy. It is important to discontinue gemcitabine at the onset of TMA and consider TMA when using gemcitabine for long periods.

Background: In the Yttrium-90 Microspheres in Cholangiocarcinoma (MISPHEC) single-arm phase 2 trial, concomitant chemotherapy and selective internal radiotherapy (SIRT) showed antitumor activity as a first-line treatment of unresectable intrahepatic cholangiocarcinomas (ICCs). In this sub-analysis, we aimed to evaluate one of the secondary endpoints, the health-related quality of life (QoL), evaluated with an EORTC QLQ-C30 instrument at the baseline and during treatment. Methods: The MISPHEC trial included treatment-naïve patients with an unresectable ICC between November 2013 and June 2016. Patients received concomitant first-line chemotherapy with cisplatin and gemcitabine for 8 cycles, SIRT was administered during cycle 1 (for patients with unilobar disease) or cycles 1 and 3 (for patients with bilobar disease) using glass Yttrium-90 microspheres. We evaluated the QoL—measured by the QLQ-C30 questionnaire—at the baseline, every 8 weeks during chemotherapy and follow-up, between 12 and 15 weeks after embolization and every 12 weeks after a liver resection if applicable. Results: A total of 41 patients were included, of which 34 completed questionnaires at the baseline. No clinically significant changes in the global health score or the sub-scales of the QLQ-C30 were observed during follow-up. The physical, social and role function mean score worsened during treatment and fatigue, nausea and pain scores increased although the differences were not clinically significant. In patients undergoing subsequent surgery, the QoL was not impaired. Conclusions: A combination of SIRT and chemotherapy with gemcitabine and cisplatin as the first-line treatment of unresectable ICCs was found to maintain the QoL.

Pancreatic cancer is the third most common cause of cancer-related deaths in the United States. Although gemcitabine is the standard of care for most patients with pancreatic cancer, its efficacy is limited by the development of resistance. This resistance may be attributable to the evasion of apoptosis caused by the overexpression of BCL-2 family antiapoptotic proteins. In this study, we investigated the role of BCL-XL in gemcitabine resistance to identify a combination therapy to more effectively treat pancreatic cancer. We used CRISPR-Cas9 screening to identify the key genes involved in gemcitabine resistance in pancreatic cancer. Pancreatic cancer cell dependencies on different BCL-2 family proteins and the efficacy of the combination of gemcitabine and DT2216 (a BCL-XL proteolysis targeting chimera or PROTAC) were determined by MTS, Annexin-V/PI, colony formation, and 3D tumor spheroid assays. The therapeutic efficacy of the combination was investigated in several patient-derived xenograft (PDX) mouse models of pancreatic cancer. We identified BCL-XL as a key mediator of gemcitabine resistance. The combination of gemcitabine and DT2216 synergistically induced cell death in multiple pancreatic cancer cell lines in vitro. In vivo, the combination significantly inhibited tumor growth and prolonged the survival of tumor-bearing mice compared with the individual agents in pancreatic cancer PDX models. Their synergistic antitumor activity is attributable to DT2216-induced degradation of BCL-XL and concomitant suppression of MCL-1 by gemcitabine. Our results suggest that DT2216-mediated BCL-XL degradation augments the antitumor activity of gemcitabine and their combination could be more effective for pancreatic cancer treatment.

Purpose Despite curative resection, the 5-year survival for patients with resectable pancreatic cancer is less than 20%. Recurrence occurs both locally and at distant sites and effective multimodality adjuvant treatment is needed.Materials and Methods Patients with curatively resected stage IB-IIB pancreatic adenocarcinoma were eligible. Treatment consisted of chemotherapy with gemcitabine 1,000 mg/m2 on days 1 and 8 and cisplatin 60 mg/m2 on day 1 every 3 weeks for two cycles, followed by chemoradiotherapy (50.4 Gy/28 fx) with weekly gemcitabine (300 mg/m2/wk), and then gemcitabine 1,000 mg/m2 on days 1 and 8 every 3 weeks for four cycles. The primary endpoint was 1-year disease-free survival rate. The secondary endpoints were disease-free survival, overall survival, and safety.Results Seventy-four patients were enrolled. One-year disease-free survival rate was 57.9%. Median disease-free and overall survival were 15.0 months (95% confidence interval [CI], 11.6 to 18.4) and 33.0 months (95% CI, 21.8 to 44.2), respectively. At the median follow-up of 32 months, 57 patients (77.0%) had recurrence including 11 patients whose recurrence was during the adjuvant treatment. Most of the recurrences were systemic (52 patients). Stage at the time of diagnosis (70.0% in IIA, 51.2% in IIB, p=0.006) were significantly related with 1-year disease-free survival rate. Toxicities were generally tolerable, with 53 events of grade 3 or 4 hematologic toxicity and four patients with febrile neutropenia.Conclusion Adjuvant gemcitabine and cisplatin chemotherapy followed by chemoradiotherapy with gemcitabine and maintenance gemcitabine showed efficacy and good tolerability in curatively resected pancreatic cancer.

After first-line chemotherapy failure, metastatic urothelial carcinoma (mUC) patients undergo pembrolizumab (PEM) or gemcitabine and docetaxel (GD) therapy. We retrospectively investigated outcomes of second-line GD or PEM for mUC patients. A total of 198 mUC patients from Nagoya City University and affiliated hospitals who received second-line treatment were grouped according to immune check point inhibitor (ICI) availability: Groups A (pre-ICI: n = 104) and B (post-ICI: n = 94). We compared clinical outcomes using Kaplan–Meier curves. Univariate and multivariate Cox regression analyses assessed potential prognostic factors for overall survival (OS). Median OS was significantly longer for Group B [median 13.6 months, 95% confidence interval (CI): 7.6–17.6] than A (7.6 months, 5.3–8.8). By sub-group analysis, patients received no additional treatment (Naive, n = 70), or PEM or GD (Salvage, n = 24) in Group B, with median OS of Naive and A groups similar. Compared to the Salvage group, significant differences in OS were observed (median 7.6 months, 95% CI 5.3–8.8; Group A, 7.6 months, 4.7–13.8; Naive, 25.7 months, 14.0–31.0; p

Pancreatic cancer is a malignant tumor that has a high metastasis potential and restrained sensitivity to chemotherapeutic treatment, characterized by a relatively poor prognosis for patients to recover, especially with diffused and unresectable forms. This article provides an overview of relevant clinical trials on the effectiveness of various chemotherapy programs, data of scientific search for the molecular typing of pancreatic cancer. We analyzed the studies on the chemotherapy in locally advanced and metastatic pancreatic cancer, compared the effectiveness of various schemes. Materials and interpretations of clinical trials ACCORD 11 MPACT; data from PubMed, NCCN, ESMO, ASCO, FDA data. Chemotherapy with a combination of gemcitabine and nab-paclitaxel shows better efficacy and prognostic prospects in the treatment of unresectable forms of pancreatic cancer, compared to all other programs. Adverse events related to treatment, including grades 3–4, are less commonly reported with gemcitabine + nab-paclitaxel rather than with polychemotherapy treatment by other schemes. Due to the lack of registration of nab-paclitaxel (abraxane) in Ukraine, the FOLFIRINOX is the program of choice for patients with a favorable comorbidity profile, but it is associated with frequent toxic effects in patients with pancreatic cancer., Рак поджелудочной железы — злокачественная опухоль, которая имеет высокий потенциал метастазирования и умеренную чувствительность к химиотерапевтическому лечению, характеризуется сравнительно неудовлетворительным прогнозом выздоровления пациентов, особенно с распространенными и нерезектабельными формами. В данной статье представлен обзор актуальных клинических исследований по эффективности различных программ химиотерапии, данные научного поиска по молекулярному типированию рака поджелудочной железы. Мы провели анализ исследований, посвященных изучению химиотерапии при местно-распространенном и метастатическом раке поджелудочной железы, сравнение показателей эффективности различных ее схем. Были проанализированы материалы и интерпретации клинических исследований ACCORD 11 MPACT; данные PubMed, NCCN, ESMO, ASCO, FDA. Химиотерапия комбинацией препаратов гемцитабин и nab-паклитаксел демонстрирует лучшие результаты в отношении эффективности и прогностические перспективы в лечении нерезектабельных форм рака поджелудочной железы по сравнению со всеми другими программами. Побочные реакции от лечения, в том числе ІІІ–ІV степени, реже регистрируются при лечении комбинацией гемцитабин + nab-паклитаксел, чем при полихимиотерапевтическом лечении по другим схемам. В связи с отсутствием в Украине регистрации препарата nab-паклитаксел (Abraxane) программой выбора у пациентов с благоприятным профилем коморбидности является полихимиотерапия FOLFIRINOX, которая связана с частыми токсическими эффектами у пациентов с раком поджелудочной железы., Рак підшлункової залози — злоякісна пухлина, яка має високий потенціал метастазування та помірну чутливість до хіміотерапевтичного лікування, характеризується порівняно незадовільним прогнозом щодо одужання пацієнтів, особливо з поширеними та нерезектабельними формами. У даній статті подано огляд актуальних клінічних досліджень щодо ефективності різних програм хіміотерапевтичної терапії, дані щодо наукового пошуку молекулярного типування раку підшлункової залози. Проведено аналіз досліджень, присвячених вивченню хіміотерапії при місцево-поширеному та метастатичному раку підшлункової залози, порівняння показників ефективності різних її схем. Проаналізовано матеріали та інтерпретації клінічних досліджень ACCORD 11, MPACT; дані PubMed, NCCN, ESMO, ASCO, FDA. Хіміотерапія комбінацією препаратів гемцитабін та nab-паклітаксел демонструє кращі результати щодо ефективності та прогностичні перспективи при лікуванні нерезектабельних форм раку підшлункової залози порівняно з усіма іншими програмами. Побічні реакції від лікування, у тому числі ІІІ–ІV ступеня, рідше реєструються при лікуванні комбінацією гемцитабін + nab-паклітаксел, аніж при поліхіміотерапевтичному лікуванні за іншими схемами. У зв’язку з відсутністю в Україні реєстрації препарату nab-паклітаксел (Abraxane) програмою вибору у пацієнтів зі сприятливим профілем коморбідності є поліхіміотерапія FOLFIRINOX, що пов’язана з частими токсичними ефектами у пацієнтів із раком підшлункової залози.

Treatment outcomes between FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and GNP (gemcitabine with albumin-bound paclitaxel) as first-line chemotherapy regimens for metastatic pancreatic cancer (PC) were assessed according to ethnic groups categorized as Western or Asian subgroups. PubMed, EMBASE, and Cochrane library were searched. Thirteen studies were eligible in this meta-analysis. Overall survival was not significantly different between FOLFIRINOX and GNP (HR 1.00, 95% CI 0.83–1.20, P = 0.990). However, the Western subgroup showed a higher survival benefit for FOLFIRINOX over GNP (HR 0.84, 95% CI 0.74–0.95, P = 0.006) whereas the Asian subgroup showed the survival benefit for GNP over FOLFIRINOX (HR 1.29, 95% CI 1.03–1.60, P = 0.030). Progression free survival was not significantly different between the two regimens in the Western subgroup (HR 1.01, 95% CI 0.84–1.20, P = 0.950) and the Asian subgroup (HR 1.13, 95% CI 0.97–1.33, P = 0.110). Occurrence of febrile neutropenia was significantly higher in FOLFIRINOX at both ethnic subgroups; however, that of peripheral neuropathy was significantly higher only in GNP of the Asian subgroup. Therefore, pharmacoethnicity might be a factor worth considering when deciding on a frontline chemotherapeutic regimen although the overall survival was not significantly different between FOLFIRINOX and GNP for metastatic PCs.

Background Pancreatic cancer is the 8th commonest cancer and the 5th commonest cause of cancer-related death in Australia, with a 9% average 5-year survival. This study aims to investigate the effects of neoadjuvant treatment on overall survival (OS) and recurrence-free survival (RFS) in borderline resectable (BRPC) and locally advanced (LAPC) pancreatic adenocarcinoma followed by curative resection. Materials and methods Prospectively-collected demographic, medical, surgical and pathological data of patients with BRPC and LAPC treated with both neoadjuvant therapy (NAT) and surgery at a single tertiary referral centre in Australia were reviewed and analysed. Results Between 2012 and 2018, 60 patients, 34 with BRPC and 26 with LAPC, were treated with NAT followed by curative resection. The commonest neoadjuvant chemotherapy regimens were Gemcitabine + Abraxane (51.7%) and FOLFIRINOX (35.0%), with 48.3% of patients additionally receiving neoadjuvant radiotherapy. Median RFS was 30 months and median OS was 35 months. On multivariable analysis, inferior OS was predicted by enlarged loco-regional lymph nodes on initial computed tomography (p = 0.032), larger tumour size post-NAT (p = 0.006) and Common Terminology Criteria for Adverse Events post-NAT toxicity greater than grade 2 (p = 0.015). LAPC patients received more neoadjuvant chemotherapy (p = 0.008) and radiotherapy (p = 0.021) than BRPC and achieved a superior pathological response (p = 0.010). Conclusion Patients who respond to NAT likely have a favourable disease biology and will progress well following resection. It is these patients who should be selected for more aggressive upfront management, and those with resistant disease should be spared from high-risk surgery.

Objectives To compare patient-reported side effects and tolerability of full-dose Bacillus Calmette-Guerin (BCG), reduced-dose BCG, and gemcitabine one week after administration. Methods All patients from July 2019 to November 2020 receiving intravesical therapy (IVT) for non-muscle invasive bladder cancer (NMIBC) at our institution were surveyed before repeat instillation. Survey questions recorded IVT retention times and the duration and severity of the following side effects: bladder symptoms, fatigue, body aches, hematuria, fever, chills, and other. All responses were collected and quantified in a de-identified, password-protected database. Statistical analysis was performed using SAS JMP 13. Results Of 592 surveys completed, symptoms of any kind were reported on 463 surveys (78%) with the most common symptoms including bladder symptoms (59%), fatigue (52%), body aches (26%), and hematuria (18%). Patients were able to hold full-dose BCG, reduced-dose BCG, and gemcitabine for the protocol-specified duration 87%, 95%, and 71% of the time (P Conclusion Significant differences in the side effects and tolerability of full-dose BCG, reduced-dose BCG, and gemcitabine were demonstrated using this novel survey, and these differences are of value for informing IVT selection. Evaluation of IVTs other than gemcitabine and BCG will further inform selection of therapies for NMIBC.

This phase 1, multi‐center, nonrandomized, open‐label, dose‐escalation study consisted of Part A wherein merestinib 80 or 120 mg (40‐mg tablets) was administered orally QD during a 28‐day cycle to patients diagnosed with solid tumors and Part B wherein merestinib 80 mg (40‐mg tablets) was administered orally QD, and cisplatin 25 mg/m2 + gemcitabine 1000 mg/m2 administered IV on Day 1 and Day 8 of a 21‐day cycle (for a maximum of eight cycles) to patients diagnosed with biliary tract carcinoma (BTC). Nineteen patients were screened and 18 patients were (Part A, n = 10; Part B, n = 8) enrolled in the trial and received treatment. All patients in Parts A and B were from Japan and were within an age range of 43–73 years, with an ECOG PS of 0.1. No dose‐limiting toxicity or deaths were experienced in the study. Dose‐limiting toxicity equivalent toxicity of Grade 4 platelet count decreased (n = 1) and was observed in Part B. In Part A, treatment‐related Grade ≥3 TEAEs were reported in one patient (PT: ALT increased and AST increased), while in Part B, five patients reported treatment‐related Grade ≥3 TEAEs with four of the five patients reporting an event of neutrophil count decreased. No complete response was reported in either Part. One patient in Part B reported partial response while four patients in each part reported stable disease. Merestinib monotherapy was concluded to be tolerable in Japanese patients, and its combination with cisplatin and gemcitabine is a tolerable regimen for Japanese patients with BTC. Trial registration: NCT03027284 (ClinicalTrials.gov) registered on 23 January 2017., The article describes the findings of Study I3O‐JE‐JSBG. The results of this phase 1, multicenter, nonrandomized, open‐label, dose‐escalation study showed that merestinib monotherapy is tolerable in Japanese patients, and its combination with cisplatin and gemcitabine is a tolerable regimen for Japanese patients with biliary tract cancer.
