CD3xCD20 bispecific monoclonal antibodies (BsAb) (epcoritamab, glofitamab) provide overall and complete responses of around 60% and 40%, respectively, in R/R diffuse large-cell B lymphomas (DLBCL).

Patients received a median of 1 prior line of treatment (range, 0–6) for WM, including 4 treated with a BTK inhibitor (2 with ibrutinib, 1 with zanubritinib and 1 received both successively). 4 patients had concurrent diagnosis of WM and DLBCL. For the others, the median time from WM to HT was 5.3 years (range, 0.4–12.8) and 15 months (range, 1–48) from HT diagnosis to BsAb. Patients had received a median of 2 prior lines (range, 1–5) for HT. Five patients were previously treated with CAR T-cell, including 2 with prior ASCT. At the time of BsAb, 75% of patients were refractory to the last treatment, and 67% to at least 2 consecutive lines. The median age was 80 years (range, 45–86). Patient treated with glofitamab had received a median of 9 cycles (6–12) and those treated with epcoritamab a median of 3 cycles (2–6). Best ORR was 92% and best CRR was 42%. CRS occurred in 10 patients (83%, with only 1 grade 3) and ICANS in 2 patients (17%, no grade 3–4). Seven patients (58%) presented infections, including 4 grade 3.

A broader role may be rational given MCL’s propensity for profound but inconsistent radiosensitivity. Common molecular alterations in MCL impact prognosis, namely TP53 mutations (TP53mut). TP53mut can influence systemic therapy choices but its impact on radiosensitivity, or RT decision making is unclear. Better understanding could guide precision radiotherapy.</p><p><b>Methods:</b> We analyzed patients (pts) treated with RT for MCL from 2010 to 2024, focusing on a cohort with next generation sequencing (NGS) for somatic genetic alterations (<i>n</i> = 66). Age and stage at RT, treatment intent, relapsed status, site of RT, and prior systemic therapy were collected. Sites treated in pts with TP53mut versus without TP53mut (TP53wt) were compared. Lesion SUV and diameter, extranodal (EN) status of the treated site, blastoid histology, RT dose, and metabolic response at first assessment were compared. Additionally, sites receiving very low dose radiotherapy (VLDRT, 4 Gy) and sites of local failure (LF) were analyzed.</p><p><b>Results:</b> 66 patients were identified, treated to 97 sites. 84 sites (87%) were treated in the relapsed setting. 54 sites (56%) were localized relapsed or early-stage disease. By site, median follow up after RT was 1.5 years. 61 sites (64%) treated were EN. Median RT dose was 30 Gy (4–40 Gy), median lesion diameter was 3.5 cm (0.9–22 cm), and median SUV max was 7.5 (0–61.6). 80% (<i>n</i> = 77) of sites had available PET response assessment at a median of 1.7 months (0.1–7.1) post-RT. Overall response rate (ORR) was 98.7%, and complete response (CR) rate (CRR) was 81% (<i>n</i> = 62). 32% of pts (<i>n</i> = 21) treated to 33 sites (34%) harbored TP53mut. ORR and CRR were 100% and 83% in TP53wt and 96% and 80% in TP53mut. RT dose (<i>p</i> = 0.817) and CR% (<i>p</i> = 0.491) did not differ by TP53 status. When analyzed by site, TP53mut had significantly worse 1-year FFLP than TP53wt (100 % vs. 85%; <i>p</i> = 0.002). 6 sites overall (6.2%) had LF; of note, 4 of 6 sites received only 4 Gy. TP53mut status was associated with higher risk of LF (<i>p</i> = 0.024). Analysis of sites treated to 4 Gy (<i>n</i> = 14; 14.4%) revealed that TP53mut remained associated with increased risk of LF (<i>p</i> = 0.002). For sites receiving > 4 Gy (<i>n</i> = 83; Median dose 30 Gy, Range 10–40 Gy), presence of TP53mut (<i>n</i> = 30) suggested association with FFLP, though not signficant (<i>p</i> = 0.069).

Initial results from the SEQUOIA study (NCT03336333), at a median follow-up of 26.2 months, demonstrated superior progression-free survival (PFS) by independent review with zanubrutinib versus bendamustine + rituximab (arms A and B) in patients with treatment-naive CLL/SLL without del(17p) as well as high overall response rate (ORR) and PFS benefit in patients with del(17p) (arm C). Additionally, the 5-year follow-up in arm A demonstrated durable PFS benefit, with estimated 54- and 60-month PFS rates of 80% and 76%, respectively.

Investigator-assessed PFS, overall survival (OS), ORR, and safety/tolerability were evaluated. Adverse events (AEs) were recorded until disease progression or start of next-line therapy.</p><p><b>Results:</b> Between Feb 2018 and Mar 2019, 111 treatment-naive patients with del(17p) were enrolled to receive zanubrutinib. The median age was 71 years (range, 42–87 years), 79 (71%) were male, 67 (60%) were IGHV unmutated, and 47 (42%) had both del(17p) and <i>TP53</i> mutation. At a median follow-up of 65.8 months (range, 5–75 months), median PFS was not reached. The estimated 60-month PFS rate was 72.2% (62.4%–79.8%) (Figure), or 73.0% (63.3%–80.6%) when adjusted for COVID-19. Median OS was also not reached. The estimated 60-month OS rate was 85.1% (76.9%–90.6%), or 87.0% (79.0%–92.1%) when adjusted for COVID-19. The ORR was 97.3%, and the complete response/complete response with incomplete hematologic recovery rate was 18.2%. Zanubrutinib treatment was ongoing in 62.2% of patients. The most common causes for treatment discontinuation were AEs and progressive disease (in 17.1% and 15.3%, respectively). Key AEs of interest (AEI) included any-grade infection (82%), bleeding (60%), neutropenia (19%), hypertension (18%), anemia (9%), thrombocytopenia (8%), and atrial fibrillation/flutter (7%).

We assessed whether the treatment benefits of N+AVD applied to potentially socioeconomically vulnerable populations.</p><p><b>Methods:</b> S1826 was a multicenter trial for patients ≥ 12 years old with stage III or IV newly diagnosed cHL. The trial was stopped early at its pre-specified second interim analysis due to efficacy of the N+AVD arm (hazard ratio [HR] for progression or death, 0.48; 95% confidence interval [CI], 0.27–0.87, <i>p</i> = 0.001). We assessed whether there was any evidence of differential benefit of N+AVD with respect to PFS according to categories of race/ethnicity (Black race and/or Hispanic ethnicity vs. others), rural versus urban residence, area-level socioeconomic deprivation (Area Deprivation Index [ADI] above median, yes vs. no), and insurance status (Medicaid or no insurance vs. others) using interaction tests. Analyses were conducted using Cox regression adjusting for the study-specified stratification variables including age (12 –17 vs. 18–60 vs. > 60 years), the international prognostic score (IPS; 0–3 vs. 4–7), and intent to use radiation (yes vs. no). An overall Type I error rate of alpha = 0.10 was used; multiplicity was accounted for by specifying each individual test at the two-sided alpha = 0.025 level using Bonferroni. If no interaction was found, the marginal association of socioeconomic variables and PFS using multivariable Cox regression was examined.</p><p><b>Results:</b> Of N = 970 eligible patients, 90% were < 60 years, and 56% were male; 11.8% were Black, 12.7% were Hispanic, and 32% had IPS 4–7.

Accumulation of NETs in tissues and blood can contribute to increased inflammation, thrombosis and organ damage. In several types of solid cancers, NETs have been shown to facilitate metastasis and tumour growth, leading to a worse prognosis. However, little is known about the role of NETs in malignant lymphomas.</p><p><b>Methods:</b> The concentration of NETs was analysed in plasma samples taken at diagnosis from patients with diffuse large B-cell lymphoma (DLBCL, <i>n</i> = 227) and classical Hodgkin lymphoma (cHL, <i>n</i> = 117) in the Uppsala Umeå Comprehensive Cancer Consortium (U-CAN) biobank. Plasma from blood donors (<i>n</i> = 54) were used as healthy controls. NETs were measured using a commercial enzyme-linked immunosorbent assay (ELISA) targeting complexes of citrullinated histones and extracellular DNA, a biomarker with high specificity for NETs.
