Summary: URBAN is a multicentric, ambispective study evaluating the effectiveness and safety of obinutuzumab‐based immuno‐chemotherapy and maintenance in patients with untreated advanced follicular lymphoma (FL). The study began before the COVID‐19 emergency declaration in Italy. It is currently ongoing for follow‐up, and the enrolment timeline encompassed different stages of the pandemic, various vaccination roll‐out phases and prevalence of SARS‐CoV‐2 variants. Outcomes of interest of the present sub‐analysis included SARS‐CoV‐2 infection rates and COVID‐19‐related hospitalizations/deaths. At data cut‐off, 86 (28.8%) and 213 patients (71.2%) were treated before and during/after the COVID‐19 outbreak respectively; 294 (98.3%) completed the induction, 31 (10.4%) completed maintenance and 170 (56.9%) were still on maintenance. Overall, 245 patients (81.9%) received at least one SARS‐CoV‐2 vaccine dose: 13.5%, 31.4% and 55.1% received one, two and three doses respectively. We observed a substantial decrease in COVID‐19‐related mortality rates in pre‐ versus post‐vaccination phases, along with a reduction in COVID‐19‐related outcomes due to the shift from alpha/delta to omicron variant predominance. No differences emerged between patients given maintenance or not, although the schedule was modified in 65% of cases. To our knowledge, URBAN represents the largest dataset of COVID‐19‐related outcomes in FL patients extensively exposed to obinutuzumab. ClinicalTrials.gov identifier: NCT04034056.

B Conclusions: b With approximately 9 mo of follow-up, pembro 400 mg Q6W had robust antitumor activity in pts with R/R cHL and R/R PMBCL, with ORR similar to that with pembro 200 mg Q3W. B Introduction: b Pembrolizumab (pembro) was originally approved by the FDA for the treatment of R/R cHL and R/R PMBCL at 200 mg every 3 weeks (Q3W). Treatment-related AEs occurred in 24 pts (40%) with R/R cHL and 2 (33.3%) with R/R PMBCL; grade >=3 treatment-related AEs occurred in 3 pts (5%) and 1 pt (16.7%), respectively.

B Conclusions: b LNM and MTV, both assessed in baseline PET/CT, turned out as the most frequently used tools to guide treatment in RAFTING trial, superseding PET-2 and possibly paving the way to future eHL Tx options based on new metrics in baseline PET/CT. B Introduction: b The efficacy of combined-modality treatment (Tx) with chemotherapy (CT) and radiotherapy (RT) in early-stage Hodgkin Lymphoma (eHL) is offset by long-term morbidity, with a cumulative incidence of 2nd primary malignancy at 40 years of 48.5% (Schaapveld 2015). Baseline-PET derived metrics are the most relevant factors for risk stratification in early-stage nonbulky HL: preliminary results of the RAFTING trial. [Extracted from the article]

The effects of storage days (0–56) and temperature (4.4, 7 or 10C) on appearance and textural sensory characteristics of conventional milk yogurt were evaluated. Covariate analysis determined the effects of storage days, temperature and their interaction on 20 sensory variables. Time–temperature interaction and temperature effects were not significant for any sensory response. The sensory variables significantly affected by time were: five of 10 appearance attributes (color description, brightness, evenness, particle intensity, distribution) and six of 10 texture attributes (hand-felt [HF]: slipperiness, ropiness, firmness; mouthfelt [MF]: viscosity, slipperiness, firmness). Color, particles and distribution increased in intensity over storage and temperature. Slipperiness and firmness increased for both HF and MF textures. Ropiness HF and viscosity MF increased over time. Correlation analyses within each of the two sensory groupings included only those significantly affected by time. Principal component analysis was moderately effective at reducing dimensionality. PRACTICAL APPLICATIONS Appearance and textural attributes of conventional milk yogurt and the effects of storage time and temperature can be monitored using descriptive analysis. Measurement of yogurt's textural attributes includes both mouthfelt and hand-felt attributes that are equally important to the overall quality of yogurt. This research adds dimensionality to the descriptive textural attributes of yogurt by evaluating both sensory categories. The changing pace of food and dairy science demonstrates the need for descriptive knowledge that can be transferred easily into predictive knowledge. Dairy manufacturers can refer to descriptive studies to characterize the sensory attributes of yogurt at a specific age or storage time to determine marketability of the stored product. Consumers can be critical of the perceived sensory characteristics of foods, thus making it additionally important for the dairy industry to monitor the quality and acceptability of conventional milk yogurt.

Background Although the stomach is the most frequent site of intestinal lymphomas, few data are available on both clinical endoscopic presentation of gastric lymphoma and possible differences between low-grade and high-grade lymphomas. Methods Clinical, histological and endoscopic records of consecutive patients with primary low-grade or high-grade lymphoma diagnosed were retrieved. Symptoms were categorized as ‘alarm’ or ‘not alarm’. The endoscopic findings were classified as ‘normal’ or ‘abnormal’. Results Overall, 144 patients with primary gastric lymphoma were detected, including 74 low-grade and 70 high-grade lymphoma. Alarm symptoms, particularly persistent vomiting and weight loss, were more frequently present in patients with high-grade lymphoma than in those with low-grade lymphoma (54% vs. 28%; P = 0.002). Low-grade lymphomas presented as ‘normal’ appearing mucosa (20% vs. 0%; P = 0.0004) or petechial haemorrhage in the fundus (9% vs. 0%; P = 0.02) more frequently than high-grade lymphomas, being also more often confined to the antrum (47% vs. 27%, P = 0.03) and associated with Helicobacter pylori infection (88% vs. 52%, P < 0.0001). On the contrary, high-grade lymphomas presented more commonly as ulcerative type (70% vs. 52%; P = 0.03), being also more frequently diagnosed in stage >I when compared with low-grade lymphomas (70% vs. 21%, P < 0.0001). Conclusions The overall prevalence of alarm symptoms is quite low and may be absent in more than 70% of patients with low-grade lymphoma. [ABSTRACT FROM AUTHOR]

Objectives The objectives of the present study are to review the technique of endoscopic staple-assisted esophagodiverticulostomy (ESED) for the treatment of Zenker's diverticulum and to describe our e-perience and modifications with ESED and the advantages of ESED over previous treatments of Zenker's diverticulum. Study Design Retrospective review of 74 cases of ESED performed for the treatment of Zenker's diverticulum. Methods Patient's records were retrospectively reviewed and tabulated for age, se-, size of diverticulum, symptoms, duration of symptoms, operative time, length of postoperative hospital stay, oral intake, complications, and relief of symptoms. Results The senior author (r.l.s.) previously reported results in 36 cases of ESED performed in 34 patients with Zenker's diverticulum. We have performed an additional 38 cases of ESED in 37 patients between March 1997 and August 1999. The rate of success of ESED was similar between the two series. The average perioperative time, time until oral intake, and length of postoperative hospital stay decreased in the second series. Overall, there were no mortalities and few complications with ESED. Compared with other forms of treatment of Zenker's diverticulum, such as Dohlman's procedure, diverticulectomy, and diverticulopexy, ESED has a similar rate of success, decreased perioperative time, decreased convalescence, and decreased mortality and complications. Conclusions Cost-effectiveness, safety, and efficacy of ESED offer new advantages over previously used treatments for Zenker's diverticulum. These results continue to support the use of ESED as the initial treatment of choice for patients with Zenker's diverticulum. [ABSTRACT FROM AUTHOR]

The Lugano classification for response assessment in lymphoma recommends the use of the 5-point-scale Deauville Score (DS) to assess response evaluation of end-of-treatment FDG-PET/CT (eotPET) in Hodgkin Lymphoma (HL); nevertheless, there is a paucity of data on its accuracy and reproducibility. We focus here on the cohort of advanced stage IIb-IV HL patients enrolled in the HD0607 clinical trial (NCT identifier 00795613) that having had a negative interim PET performed 6 cycles of ABVD (Doxorubicin, Vinblastine, Vincristine and Dacarbazine) and then performed an eotPET. Negative patients were randomized to radiotherapy and no further treatment while positive patients were treated based on local policies. eotPET was re-evaluated independently by two readers evaluated and progression free survival was analysed (PFS). eotPET of 254 patients were analysed. The median follow-up was 43 months. The best receiver operator characteristics cut-off values to distinguish positive and negative patients was 4. The area-under-the-curve was 0.81 (95%CI, 0.70-0.91). Three-years PFS was 0.95 (95% CI 0.90-0.97) in eotPET negative and 0.22 (95% CI 0.11-0.43) in eotPET positive. DS demonstrated a good reproducibility of positivity/negativity between the readers consensus and local site evaluation where the agreement occurred on 95.0% of patients. The present study demonstrates that eotPET is an accurate tool to predict treatment outcome in HL and confirms the appropriateness of the Lugano classification for eotPET evaluation., (© 2022 John Wiley & Sons Ltd.)

Acalabrutinib, a Bruton tyrosine kinase inhibitor, demonstrated greater selectivity and improved safety versus ibrutinib in a head-to-head trial in relapsed/refractory (R/R) chronic lymphocytic leukaemia. In the R/R marginal zone lymphoma (MZL) cohort (phase 2) of a phase 1b/2 trial (NCT02180711), 43 patients with MZL and at least one prior therapy received acalabrutinib 100 mg twice daily until disease progression or unacceptable toxicity [median age 69 years (range 42-84); median one (1-4) prior systemic regimens]. Median follow-up was 13.3 months (range 0.5-45.5). Among 40 patients evaluable for response, investigator-assessed overall response rate was 53% [95% confidence interval (CI) 36%-69%] with five (13%) complete responses. Tumour reduction occurred in 40 (93%) of the treated patients. Median time to response was 2.9 months (median duration of response not estimable). Estimated median progression-free survival (PFS) was 27.4 months (12-month PFS rate, 67%). Five patients died (disease progression, n = 4; septic shock, n = 1). Seventeen patients (40%) had grade 3 or higher adverse events (AEs), most commonly neutropenia (14%), anaemia, dyspnoea (7% each), fatigue and thrombocytopenia (5% each). Hypertension occurred in 5%; atrial fibrillation/flutter and major haemorrhage were not reported. AEs led to treatment discontinuation in three (7%) patients. Acalabrutinib was active and well tolerated in patients with R/R MZL., (© 2022 The Authors. British Journal of Haematology published by British Society for Haematology and John Wiley & Sons Ltd.)

The standard management for relapsed or refractory classical Hodgkin lymphoma (cHL) is salvage therapy followed by autologous stem cell transplantation (ASCT). This strategy allows almost 50% of patients to be cured. Post-ASCT maintenance treatment with brentuximab vedotin (BV) confers improved progression-free survival (PFS) to cHL patients at high risk of relapse. We investigated the outcome of 105 cHL patients receiving post-ASCT BV maintenance in the real-life setting of 23 Italian hematology centers. This population included naïve patients and those previously exposed to BV. Median follow-up was 20 months. Patients presented a median of two lines of treatment pre-ASCT, with 51% receiving BV. Twenty-nine percent of patients had at least two high-risk factors (refractory disease, complete response [CR] less than 12 months, extranodal disease at relapse), while 16% presented none. At PET-CT, a Deauville score (DS) of 1-3 was reported in 75% and 78% of pre- and post-ASCT evaluations, respectively. Grade 3-4 adverse events (AEs), mainly peripheral neuropathy, were observed in 16% of patients. Three-year PFS and overall survival (OS) were 62% and 86%, respectively. According to BV exposure, 3-year PFS and OS were 54% and 71%, respectively, for naïve and 77% and 96%, respectively, for previously exposed patients. Refractory disease (hazard ratio [HR] 4.46; p = 0.003) and post-ASCT DS 4-5 (HR 3.14; p = 0.005) were the only two factors significantly associated with PFS reduction in multivariable analysis. Post-ASCT BV maintenance is an effective, safe treatment option for cHL naïve patients and those previously exposed to BV., (© 2021 The Authors.

Among patients with advanced-stage classical Hodgkin lymphoma (cHL) receiving ABVD chemotherapy, PET performed after the first two treatment cycles (PET-2) has prognostic value. However, 15% of patients with a negative PET-2 will experience treatment failure. Here we prospectively evaluated serum thymus and activation-regulated chemokine (TARC) levels, to improve risk assessment in patients treated according to HD0607 PET-driven trial (#NCT00795613). In 266 patients with available serum samples, who have agreed to participate in a sub-study for assessment of the role of TARC monitoring, serum TARC levels were measured at baseline and at time of PET-2 by commercially available ELISA test kits. The primary end-point was to evaluate the association between TARC after 2 ABVD cycles and PFS. Median TARC-2 values were significantly higher in PET-2-positive patients compared to PET-2-negative patients (P = .001), and in patients with treatment failure compared to those in continuous CR (P = .01). The 4-year PFS significantly differed between patients with TARC-2 >800 pg/mL vs ≤800 pg/mL (64% vs 86%, P = .0001). Moreover, among PET-2-negative patients, elevated TARC-2 identified those with a worse prognosis (74% vs 89%; P = .01). In multivariable analysis, TARC-2 >800 pg/mL was a significant independent predictor of PFS in the whole study population (HR 2.39, P = .004) and among the PET-2-negative patients (HR 2.49, P = .02). In conclusion, our results indicate that TARC-2 serum levels above 800 pg/mL suggest the need for a stringent follow-up in PET-2-negative patients, and the evaluation of new drugs in PET-2-positive, who will likely fail to respond to intensification with escalated BEACOPP., (© 2020 John Wiley & Sons Ltd.)

The improvements in magnetic resonance imaging (MRI) technology and the concern related to the increased cancer risk in patients with lymphoma, also due to radiation exposure associated with imaging examinations, have led to the introduction of whole-body MRI (WB-MRI) as a radiation-free alternative to standard imaging procedures. WB-MRI seems a less histology-dependent functional imaging test than 18 F-fluorodeoxyglucose-positron emission tomography/CT ( 18 F-FDG-PET/CT). In patients with FDG-avid lymphomas, such as diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL), 18 F-FDG-PET/CT remains the imaging reference standard for staging, with WB-MRI potentially being a complementary modality that could replace CT, especially in young patients. On the other hand, WB-MRI is a valuable imaging procedure for lymphoma surveillance and in lymphomas with variable/low FDG avidity and nonfollicular indolent lymphomas. The aim of this paper is to discuss the current state of the art of WB-MRI in lymphoma by evaluating its diagnostic performance in different lymphoma subtypes: Hodgkin, aggressive, and indolent lymphomas., (© 2019 John Wiley & Sons, Ltd.)

Splenectomy in addition to immunotherapy with rituximab can provide quick and sometimes durable disease control in patients with splenic marginal zone lymphoma (SMZL). However, systemic chemotherapy is ultimately required in many cases. The BRISMA (Bendamustine-rituximab as first-line treatment of splenic marginal zone lymphoma)/IELSG (International Extranodal Lymphoma Study Group)36 trial is an open-label, single arm phase II study designed by the IELSG in cooperation with the Fondazione Italiana Linfomi and the lymphoma Study Association according to Simon's two-stage method. The primary endpoint was complete response rate. Fifty-six patients with SMZL diagnosis confirmed on central revision were treated with bendamustine (90 mg/m 2  days 1, 2) and rituximab (375 mg/m 2  day 1) every 28 days for six cycles (B-R). The overall response and CR rates were 91% and 73%, respectively. Duration of response, progression-free survival and overall survival at 3 years were 93% (95% confidence interval [CI] 81-98), 90% (95% CI 77-96) and 96% (95% CI 84-98), respectively. Toxicity was mostly haematological. Neutropenia grade ≥3 was recorded in 43% of patients; infections and febrile neutropenia in 5·4% and 3·6%. Overall, 14 patients (25%) experienced serious adverse events. Five patients (9%) went off-study because of toxicity and one patient died from infection. In conclusion, B-R resulted in a very effective first-line regimen for SMZL. Based on the results achieved in the BRISMA trial, B-R should be considered when a chemotherapy combination with rituximab is deemed necessary for symptomatic SMZL patients., (© 2018 British Society for Haematology and John Wiley & Sons Ltd.)

The peripheral blood lymphocyte to monocyte ratio (LMR) at diagnosis can be clinically relevant in patients with diffuse large B-cell lymphoma (DLBCL). We reviewed the outcome of 1,057 DLBCL patients followed from 1984 to 2012 at four centers. LMR was analyzed as a clinical biomarker by receiver-operating characteristic (ROC) analysis and Harrell's C-statistics. Patients were characterized by a median age of 61 years, International Prognostic Index (IPI) score of >2 in 39%, and were treated with a rituximab-containing chemotherapy in 66%. LMR proved strongly predictive for survival in patients treated with rituximab-based programs, but not in those receiving chemotherapy alone. Additionally, an LMR value of ≤2.6 (as determined by ROC analysis) was associated with a worst performance status, a higher lactate dehydrogenase (LDH) level, an advanced clinical stage, and a higher IPI score (P = 0.000). In patients treated with rituximab-supplemented chemotherapy programs, an LMR value of <2.6 was found in most of the primary refractory patients (75%) which proved as the best cutoff to predict both response and survival (P = 0.018). Finally, multivariate analysis and Harrell's C-statistics confirmed the IPI-independent role of LMR on survival (P = 0.0000). In conclusion, LMR is a potent predictor of clinical response and survival in DLBCL treated with rituximab-containing chemotherapy., (Copyright © 2013 Wiley Periodicals, Inc.)

Unlabelled: Interim 2-[18F]Fluoro-2-deoxy-D-glucose Positron Emission Tomography performed after two chemotherapy cycles (PET-2) is the most reliable predictor of treatment outcome in ABVD-treated Hodgkin Lymphoma (HL) patients. We retrospectively analysed the treatment outcome of a therapeutic strategy based on PET-2 results: positive patients switched to BEACOPP, while negative patients continued with ABVD. Between January 2006 and December 2007, 219 newly diagnosed HL patients admitted to nine centres were enrolled; 54 patients, unfit to receive this treatment were excluded from the analysis. PET-2 scans were reviewed by a central panel of nuclear medicine experts, according to the Deauville score (Meignan, 2009). After a median follow up of 34 months (12-52) the 2-year failure free survival (FFS) and overall survival for the entire cohort of 165 patients were 88% and 98%; the FFS was 65% for PET-2 positive and 92% for PET-2 negative patients. For 154 patients in which treatment was correctly given according to PET-2 review, the 2-year FFS was 91%: 62% for PET-2 positive and 95% for PET-2 negative patients., Conclusions: this strategy, with BEACOPP intensification only in PET-2 positive patients, showed better results than ABVD-treated historic controls, sparing BEACOPP toxicity to the majority of patients., (© 2011 Blackwell Publishing Ltd.)
