The article describes the case of a 63-year-old man diagnosed with chronic lymphocytic leukemia (CLL) who presented with Rai stage II, and cells expressing Zap-70, CD38, mutated IGHV phenotypes, with trisomy 12 and 11q.23 del. Topics discussed include the treatment given to the patient, his symptoms developed 18 months after Ibrutinib initiation, and his condition after starting on blinatumomab.

Post-transplant lymphoproliferative disorder (PTLD) develops in 1-3% of liver transplant recipients and no consensus exists about therapeutic management. From 2006 to 2016, 1489 liver transplants were performed at our institution with 20 patients (incidence 1.3%) developing PTLD. Hepatitis C virus (HCV) was the leading cause (n = 10) of liver transplant in PTLD patients. Diffuse large B-cell lymphoma was the most frequent histologic subtype (n = 17), and we report our experience in the management of these patients. Patients were treated with frontline immunochemotherapy without immunosuppression reduction. All evaluable patients achieved a complete remission. Statistically significant decreased survival was identified in HCV-positive patients. Six patients (60%) exhibited increases in HCV RNA levels during therapy. Four patients (40%) developed graft failure and three of them (30%) died from liver dysfunction. This is the first study providing evidence of decreased survival in HCV-positive PTLD patients after liver transplant receiving immunochemotherapy. [ABSTRACT FROM AUTHOR]

The article discusses a study on the characteristics and outcomes of lymphoblastic lymphoma (LBL). The study examined the outcomes of the treatment of 34 LBL patients an academic center in Florida. Seventy percent of the patients experienced complete remission (CR) during first-line treatment. The results showed the association of elevated lactate dehydrogenase (LDH) with inferior overall survival (OS).

Loncastuximab tesirine (loncastuximab tesirine-lpyl; Lonca), an FDA-approved antibody drug conjugate (ADC) comprising a CD19-targeted antibody conjugated to a pyrrolobenzodiazepine (PBD) dimer cytotoxin, is indicated in relapsed/refractory diffuse large B-cell lymphoma after ≥2 prior systemic therapies. Several adverse events (AEs), including edema and effusion, are likely related to the PBD cytotoxin. The objective of this project was to characterize the onset and management of edema and effusion in the pivotal LOTIS-2 trial (NCT03589469). Lonca was administered intravenously every 3 weeks (0.15 mg/kg for 2 cycles; 0.075 mg/kg for subsequent cycles). Dexamethasone premedication was administered to reduce the incidence and severity of PBD toxicities. Lonca was held for patients with Grade ≥2 edema/effusion (as defined by the Common Terminology Criteria for Adverse Events version 4.0) and spironolactone was recommended for initial management of edema or effusion. In this analysis (data cutoff: March 1, 2021), missing AE end dates were imputed using the date of new anticancer therapy, end of study, or data cutoff. In LOTIS-2 (N=145), edema occurred in 27.6% of patients; median time to onset was 40.0 days (min, max: 1, 277); and median duration was 50.5 days (2, 676). Grade ≥3 edema occurred in 3.4% of patients; median time to onset was 106.0 days (9, 183); and median duration was 5.0 days (3, 112). Effusion occurred in 11.7% of patients; median time to onset was 52.0 days (3, 234); and median duration was 20.0 days (4, 581). Grade ≥3 effusion occurred in 2.8% of patients; median time to onset was 118.0 days (17, 277); and median duration was 20.5 days (6, 411). In the total trial population, dose delays, reductions, and withdrawal occurred due to edema in 4.8%, 0.7%, and 2.8% of patients, respectively, and due to effusion in 1.4%, 0%, and 2.8% of patients, respectively. The median time to onset of any grade edema and effusion was approximately 2 and 3 treatment cycles, respectively. Incidence of Grade ≥3 edema and effusion was low and typically occurred later in therapy, with a median time to onset of approximately 6 treatment cycles. Edema and effusion were generally manageable with dose delays and modifications, which are recommended for Grade ≥2 events. [ABSTRACT FROM AUTHOR]

Marginal zone lymphoma (MZL) includes extranodal (EMZL), splenic (SMZL), and nodal (NMZL) subtypes. Histological transformation (HT) to large B-cell lymphomas is well documented but with a large variability in published cumulative incidence rates. We report results from the Molecular Epidemiology Resource (MER) cohort for the cumulative incidence of HT (with death as competing risk) and associated risk factors and outcomes. We also conduct a meta-analysis of available studies on the cumulative incidence of HT. From 2002-2015, 529 patients with MZL were enrolled in the MER (69% EMZL, 16% SMZL, 15% NMZL). Ten-year overall survival (OS) from diagnosis was 66%. HT occurred in 21 patients, with 5-year and 10-year cumulative incidence of HT of 2.7% (95% confidence interval [CI] 0.02-0.05) and 3.6% (95%CI 0.02-0.06), respectively. HT was associated with an increased risk of death (subdistribution hazard ratio (HR)=3.95; 95%CI 2.06-7.55). Predictors of HT were ≥2 extranodal sites and MALT-IPI score ≥2. OS was 79% at 5 and 55% at 10 years after HT. Age at HT≥70 years was the only predictor of OS after HT (HR=3.57; 95%CI 1.34-9.48). In meta-analysis of 12 studies (6,161 patients), the 5- and 10-year cumulative incidence of HT across all subtypes were 5% (95%CI 0.05-0.06) and 8% (95%CI 0.07-0.09), respectively. Rates were lower in EMZL (3% and 5%) than in SMZL (7% and 13%) and NMZL (9% and 13%). While HT is relatively uncommon in the first decade after MZL diagnosis, it is associated with an inferior outcome and needs new approaches to prevention and management., (Copyright © 2024 American Society of Hematology.)

Therapies that demonstrate durable, long-term responses with manageable safety and tolerability are needed for patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). Loncastuximab tesirine (loncastuximab tesirine-lpyl [Lonca]), an anti-CD19 antibody conjugated to a potent pyrrolobenzodiazepine dimer, demonstrated single-agent antitumor activity in the pivotal phase II LOTIS-2 study in heavily pretreated patients with R/R DLBCL. Here we present updated efficacy and safety analyses from LOTIS-2, performed for all patients and in subsets of patients with a complete response (CR), including patients with CR who were event-free (no progressive disease or death) for ≥1 year and ≥2 years from cycle 1, day 1 of treatment. Lonca was administered every 3 weeks (0.15 mg/kg for 2 cycles; 0.075 mg/kg for subsequent cycles). As of the final data cutoff (September 15, 2022; median follow-up: 7.8 months [range, 0.3-42.6]), 70 of 145 (48.3%) patients achieved an overall response. Thirty-six (24.8%) patients achieved CR, of which 16 (44%) and 11 (31%) were event-free for ≥1 year and ≥2 years, respectively. In the all-treated population, the median overall survival was 9.5 months; the median progression-free survival was 4.9 months. Among patients with CR, median overall survival and progression-free survival were not reached, with 24-month overall and progression-free survival rates of 68.2% (95% CI: 50.0-81.0) and 72.5% (95% CI: 48.2-86.8), respectively. No new safety concerns were detected. With additional follow-up, Lonca continued to demonstrate durable, long-term responses with manageable safety and tolerability in patients with CR (clinicaltrials gov. Identifier: NCT03589469).

Purpose: Significant progress has occurred in developing quantitative PET/CT biomarkers in diffuse large B-cell lymphoma (DLBCL). Total metabolic tumor volume (MTV) is the most extensively studied, enabling assessment of FDG-avid tumor burden associated with outcomes. However, prior studies evaluated the outcome of cytotoxic chemotherapy or chimeric antigen receptor T-cell therapy without data on recently approved FDA agents. Therefore, we aimed to assess the prognosis of PET/CT biomarkers in patients treated with loncastuximab tesirine., Experimental Design: We centrally reviewed screening PET/CT scans of patients with relapsed/refractory DLBCL enrolled in the LOTIS-2 (NCT03589469) study. MTV was obtained by computing individual volumes using the SUV ≥4.0 threshold. Other PET/CT metrics, clinical factors, and the International Metabolic Prognostic Index (IMPI) were evaluated. Logistic regression was used to assess the association between biomarkers and treatment response. Cox regression was used to determine the effect of biomarkers on time-to-event outcomes. We estimated biomarker prediction as continuous and binary variables defined by cutoff points., Results: Across 138 patients included in this study, MTV with a cutoff point of 96 mL was the biomarker associated with the highest predictive performance in univariable and multivariable models to predict failure to achieve complete metabolic response (OR, 5.42; P = 0.002), progression-free survival (HR, 2.68; P = 0.002), and overall survival (HR, 3.09; P < 0.0001). IMPI demonstrated an appropriate performance, however, not better than MTV alone., Conclusions: Pretreatment MTV demonstrated robust risk stratification, with those patients demonstrating high MTV achieving lower responses and survival to loncastuximab tesirine in relapsed/refractory DLBCL., (©2023 American Association for Cancer Research.)

Neurological emergencies are frequently catastrophic events in the course of haematological malignancies (HM) that, if not promptly recognized and treated, may lead to lethal outcomes or chronic sequelae. They may occur at any time during the disease course, but are more frequently observed following relapse. Practice guidelines are lacking in the management of most central nervous system (CNS) complications in HM. Herein we review the pathophysiology, presentation and treatment of elevated intracranial pressure, spinal cord compression, status epilepticus, neurovascular complications, CNS infection, leucostasis and hyperviscosity. Further, we discuss the expanding spectrum of neurological complications of old and novel treatments in HM., (© 2019 British Society for Haematology and John Wiley & Sons Ltd.)

Primary vitreoretinal lymphoma (PVRL) is a subset of primary CNS lymphoma that presents as isolated ocular disease without brain involvement. Although ocular radiotherapy (RT) is an effective treatment for PVRL, the optimal treatment is uncertain. PVRL may later involve the brain in 56%-85% of patients. We report on 12 PVRL patients treated with a combination of bilateral RT and a systemic chemotherapy (CT) regimen containing high-dose methotrexate (M). Ten received RT (30-40 Gy) followed by CT, one received RT, and one was treated with intravitreal M; all achieved a complete response (CR). Three patients had tumor recurrence in the brain and received CT and one patient relapsed in the eye with a second recurrence in the brain. Three patients achieved CR-2 remain alive and one died of dementia. One died from recurrent CNS disease. With a median follow of 68 months (range, 17-154 months), median progression-free and overall survival have not been reached. Bilateral RT followed by M-based CT is an effective treatment for reducing CNS progression and prolonging survival., (© 2019 Wiley Periodicals, Inc.)

Bendamustine (B) with rituximab (R) is a standard frontline treatment for medically fit follicular lymphoma (FL) patients. The safety and efficacy of maintenance rituximab (MR) after BR induction has not been formally compared to observation for FL, resulting in disparate practice patterns. Prospective trials have shown benefit of MR after R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) or R-CVP (rituximab, cyclophosphamide, vincristine, prednisone), yet recent data from the GALLIUM study comparing outcomes of patients treated with chemotherapy with R or obinutuzumab (G) showed higher than anticipated fatal adverse events with BR/BG. In order to assess the efficacy and tolerability of MR after BR, we retrospectively collected data on 640 newly diagnosed patients treated with FL. We found that patients who achieved partial remission (PR) after ≥4 cycles of BR had improved duration of response (DOR) with MR vs. no maintenance, whereas those in complete remission did not. These findings were confirmed in a validation cohort. In the entire study population, the known fatal adverse event rate after BR was 2·5% and did not significantly differ in those receiving MR versus no maintenance. [Correction added on 14 January 2019, after online publication: The preceding sentence has been corrected in this current version.] Within the limitations inherent to retrospective analysis, these data suggest that FL patients with a PR to BR experience prolongation of remission with MR with an acceptable safety profile., (© 2018 British Society for Haematology and John Wiley & Sons Ltd.)
