Summary: We evaluated the impact of liposomal doxorubicin (NPLD) supercharge‐containing therapy on interim fluorodeoxyglucose positron emission tomography (interim‐FDG‐PET) responses in high‐risk diffuse large B‐cell lymphoma (DLBCL) or classical Hodgkin lymphoma (c‐HL). In this phase II study (2016–2021), 81 adult patients with advanced‐stage DLBCL (n = 53) and c‐HL (n = 28) received front‐line treatment with R‐COMP‐dose‐intensified (DI) and MBVD‐DI. R‐COMP‐DI consisted of 70 mg/m² of NPLD plus standard rituximab, cyclophosphamide, vincristine and prednisone for three cycles (followed by three cycles with NPLD de‐escalated at 50 mg/m²); MBVD‐DI consisted of 35 mg/m² of NPLD plus standard bleomycin, vinblastine and dacarbazine for two cycles (followed by four cycles with NPLD de‐escalated at 25 mg/m²). Patients underwent R‐COMP‐DI and MBVD‐DI with a median dose intensity of 91% and 94% respectively. At interim‐FDG‐PET, 72/81 patients (one failed to undergo interim‐FDG‐PET due to early death) had a Deauville score of ≤3. At end of treatment, 90% of patients reached complete responses. In all, 20 patients had Grade ≥3 adverse events, and four of them required hospitalisation. At a median 21‐months of follow‐up, the progression‐free survival of the entire population was 77.3% (95% confidence interval 68%–88%). Our data suggest that the NPLD supercharge‐driven strategy in high‐risk DLBCL/c‐HL may be a promising option to test in phase III trials, for improving negative interim‐FDG‐PET cases incidence.

We evaluated the impact on progression-free survival (PFS) of achieving a deep metabolic response at 2-deoxy-2[¹⁸F] fluoro-d-glucose positron emission tomography (FDG-PET) in patients with refractory or relapsed (R/R) classic Hodgkin lymphoma (cHL) following a new salvage regimen named Bv+Bs (brentuximab vedotin + bendamustine supercharge), from 2013 to 2017. In this real-life study, 20 consecutive patients (aged <60 years) with R/R cHL after failure of ≥1 salvage treatments received Bv+Bs regimen consisting of 3-days outpatient IV infusions of 1.8 mg/kg of Bv on day 1 of each 3-week cycle combined in sequence to bendamustine on days 2 and 3 of the treatment cycle at a fixed dose of 120 mg/m² per day, for a total of 4 courses. A robust primary prophylaxis approach, including premedication, antimicrobials, stimulating factors, and cytomegalovirus monitoring, was systematically performed. The 20 patients (all evaluable) underwent 4 courses of Bv+Bs with a median dose intensity of 100% for both Bv and Bs. Ten patients (50%) experienced grade ≥3 treatment-related adverse events, without requiring hospitalization. At post-Bv+Bs reevaluation, 80% of patients had deep metabolic responses with Deauville 5-point scale scores ≤2. Thereafter, 14 patients (70%) received autologous hematopoietic stem cell transplantation (HSCT; peripheral blood stem cells previously harvested in 12 cases), and 4 patients (10%) received allogeneic HSCT. At a median follow-up of 27 months from Bv+Bs regimen initiation, the 2-year PFS of the entire population was 93.7% (95% confidence interval, 62.7% to 99.6%). Our data suggest that Bv+Bs regimen-driven strategy may be a promising salvage option to improve long-term control of high-risk Hodgkin lymphoma. Key Points FDG-PET–negative status achieved with salvage therapy is the most important determinant of favorable outcome after HSCT, for patients with R/R cHL. Our modified Bv+Bs salvage regimen led to deep metabolic responses in the majority of patients, establishing a bridge to transplant. Visual Abstract

The reliability and safety of front‐line ultrasonography guided core needle biopsy (UG‐CNB) performed with specific uniform approach have never been evaluated in a large series of patients with lymphadenopathies suspected of lymphoma. The aim of this study was to assess the overall accuracy of UG‐CNB in the lymph node histological diagnosis, using a standard reference based on pathologist consensus, molecular biology, and/or surgery. We retrospectively checked the findings concerning the application of lymph node UG‐CNB from four Italian clinical units that routinely utilized 16‐gauge diameter modified Menghini needle under power‐Doppler ultrasonographic guidance. A data schedule was sent to all centers to investigate the information regarding techniques, results, and complications of lymph node UG‐CNB in untreated patients over a 12‐year period. Overall, 1000 (superficial target, n = 750; deep‐seated target, n = 250) biopsies have been evaluated in 1000 patients; other 48 biopsies (4.5%), screened in the same period, were excluded because inadequate for a confident histological diagnosis. Most patients were suffering from lymphomas (aggressive B‐cell non‐Hodgkin lymphoma [aBc‐NHL], 309 cases; indolent B‐cell [iBc]‐NHL, 279 cases; Hodgkin lymphoma [HL], 212 cases; and nodal peripheral T‐cell [NPTC]‐NHL, 30 cases) and 100 cases from metastatic carcinoma; 70 patients had non‐malignant disorders. The majority of CNB results met at least one criterion of the composite reference standard. The overall accuracy of the micro‐histological sampling was 97% (95% confidence interval: 95%–98%) for the series. The sensitivity of UG‐CNB for the detection of aBc‐NHL was 100%, for iBc‐NHL 95%, for HL 93%, and for NPTC‐NHL 90%, with an overall false negative rate of 3.3%. The complication rate was low (6% for all complications); no patient suffered from biopsy‐related complications of grade >2 according to the Common Terminology Criteria for Adverse Events. Lymph node UG‐CNB as mini‐invasive diagnostic procedure is effective with minimal risk for the patient.

The basilic/brachial (BBV), internal jugular (IJV), and subclavian veins (SCV) are commonly used as central venous catheter (CVC) sites. A BBV approach [peripherally inserted central catheter (PICC)] is increasingly used for short- to intermediate-term CVCs for acute leukemias undergoing cytotoxic intensive regimens. In this retrospective study, the catheterization of the BBV, IJV, and SCV in patients with previously untreated acute leukemia was assessed. The primary outcome was the composite incidence of catheter-related symptomatic deep-vein thrombosis (sDVT) and bloodstream infection (BSI) from catheterization up to 30 days later. In a 10-year period, 336 CVC were inserted in the BBV (n = 115), IJV (n = 111), and SCV (n = 110) in 336 patients suffering from AML (n = 201) and ALL (n = 135) and undergoing induction chemotherapy. The primary outcome events were 8, 20, and 27 in the BBV, SCV and IJV cohorts (2.6, 6.9, and 9.6 per 1000 catheter-days, respectively; p = 0.002). The primary outcome risk was significantly higher in the IJV-cohort than in the BBV-cohort (HR, 3.6; 95% CI, 1.6 to 7.9; p = 0.001) and in the SCV-cohort than in the BBV-cohort (HR, 2.6; 95% CI, 1.2 to 5.9; p = 0.02). PICC was a valid CVC for the induction chemotherapy of acute leukemia for the lowest risk of sDVT and BSI.

Background: Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a rare variant of HL that accounts for 5% of all HL cases. The expression of CD20 on neoplastic lymphocytes provides a suitable target for novel treatments based on Rituximab. Due to its rarity, consolidated and widely accepted treatment guidelines are still lacking for this disease. Methods: Between 1 December 2007 and 28 February 2018, sixteen consecutive newly diagnosed adult patients with NLPHL received Rituximab (induction ± maintenance)-based therapy, according to the baseline risk of German Hodgkin Study Group prognostic score system. The treatment efficacy and safety of the Rituximab-group were compared to those of a historical cohort of 12 patients with NLPHL who received Doxorubicin, Bleomycin, Vinblastine, Dacarbazine (ABVD) chemotherapy followed by radiotherapy (RT), if needed, according to a similar baseline risk. The primary outcome was progression-free survival (PFS) and secondary outcomes were overall survival (OS) and side-effects (according to the Common Terminology Criteria for Adverse Events, v4.03). Results: After a 7-year follow-up (range, 1–11 years), PFS was 100% for patients treated with the Rituximab-containing regimen versus 66% for patients of the historical cohort (p = 0.036). Four patients in the latter group showed insufficient response to therapy. The PFS for early favorable and early unfavorable NLPHLs was similar between treatment groups, while a better PFS was recorded for advanced-stages treated with the Rituximab-containing regimen. The OS was similar for the two treatment groups. Short- and long-term side-effects were more frequently observed in the historical cohort. Grade ≥3 neutropenia was more frequent in the historical cohort compared with the Rituximab-group (58.3% vs. 18.7%, respectively; p = 0.03). Long-term non-hematological toxicities were observed more frequently in the historical cohort. Conclusion: Our results confirm the value of Rituximab in NLPHL therapy and show that Rituximab (single-agent) induction and maintenance in a limited-stage, or Rituximab with ABVD only in the presence of risk factors, give excellent results while sparing cytotoxic agent- and/or RT-related damage. Furthermore, Rituximab inclusion in advanced-stage therapeutic strategy seems to improve PFS compared to conventional chemo-radiotherapy.
