Addition of bortezomib to R-CHOP improves survival in DLBCL molecular subgroups
Key clinical point: The addition of bortezomib to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) confers a survival advantage over R-CHOP in patients with activated B-cell (ABC)- and molecular high grade (MHG)-type diffuse large B-cell lymphoma (DLBCL).
Major finding: Bortezomib-R-CHOP vs R-CHOP significantly improved 60-month progression-free survival (PFS) in the ABC (adjusted hazard ratio [aHR] 0.65; P = .041) and MHG (aHR 0.46; P = .011) groups, and overall survival (OS) in the ABC group (aHR 0.58; P = .032). The germinal center B-cell (GCB) group showed no significant difference in PFS or OS.
Study details: This updated retrospective analysis of the phase 3 REMoDL-B study included 801 adult patients with DLBCL (ABC, MHG, or GCB subtype) who were randomly assigned to receive 2-6 cycles of R-CHOP (n = 407) or bortezomib-R-CHOP (n = 394) after one cycle of R-CHOP.

Similar outcomes of CAR-T cell therapy for nodal and extra nodal DLBCL
Key clinical point: Chimeric antigen receptor (CAR)-T cell therapy after lymphodepletion led to similar survival outcomes and toxicity rates in patients with nodal (ND) and extra nodal (EN) diffuse large B-cell lymphoma (DLBCL), with outcomes being significantly worse in patients with >2 vs <3 EN sites at lymphodepletion.
Major finding: After a median follow-up of 7.5 months, patients with EN and ND DLBCL had similar median progression-free survival (PFS; 10.76 and 14.1 months, respectively; P = .126), overall survival (OS; 15.36 and 18.4 months, respectively; P = .100), and treatment-related toxicity rates. Patients with <3 vs >2 EN sites had significantly longer median PFS (P = .01) and OS (P = .05).
Study details: This real-world retrospective multicenter study included 126 patients with DLBCL of EN (n = 72) or ND (n = 42) origin who underwent lymphodepletion followed by CAR-T cell infusion with tisagenlecleucel or axicabtagene ciloleucel.

Dose-adjusted EPOCH and rituximab beneficial for selected older patients with high-risk DLBCL
Key clinical point: Sufficiently fit older patients with high-risk diffuse large B-cell lymphoma (DLBCL) achieve favorable outcomes with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R); patients with a poor performance status (PS) develop unacceptable toxicity and require less intensive therapy.
Major finding: At 3 years, the progression-free survival (PFS) and overall survival (OS) rates were 53% and 58%, respectively, and the treatment-related mortality (TRM) rate was 13%. The 3-year PFS (58% vs 32%; P < .001) and OS (64% vs 33%; P = .007) rates were significantly higher and TRM rates were significantly lower (6% vs 43%; P < .001) among patients with PS 0-2 vs 3-4.
Study details: This multicenter retrospective real-life study included 120 patients aged ≥60 years with newly diagnosed high-risk DLBCL treated with a median of 6 DA-EPOCH-R cycles per patient.
Disclosures: No information on the source of funding or conflicts of interest was provided.

Ibrutinib+BR a promising treatment option for newly diagnosed MCL ineligible for intensive therapy
Key clinical point: Compared with bortezomib, rituximab, cyclophosphamide, doxorubicin, and prednisone (VR-CAP) and rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), ibrutinib plus bendamustine and rituximab (Ibru+BR) prolongs progression-free survival (PFS) in patients with newly diagnosed mantle cell lymphoma (MCL) who are ineligible for intensive therapy.
Major finding: Ibru+BR significantly improved PFS compared with VR-CAP (hazard ratio [HR] 0.55; P = .03) and R-CHOP (HR 0.35; P < .001). Adverse event risks were not significantly different in the Ibru+BR, VR-CAP, R-CHOP, and BR treatment arms.
Study details: The data come from a network meta-analysis of 3 studies involving 1459 patients with newly diagnosed MCL who were ineligible for intensive therapy and received first-line Ibru+BR, VR-CAP, R-CHOP, or BR.
Disclosures: This study did not report the source of funding. The authors declared no conflicts of interest.

Real-world data support the continued use of second-line targeted therapies in CLL
Key clinical point: Compared with chemoimmunotherapy, second-line targeted therapies improved treatment-free survival (TFS) and tended to improve overall survival (OS) in patients with chronic lymphocytic leukemia (CLL), including those who were frail and had comorbidities.
Major finding: The 3-year TFS and estimated OS rates were higher in patients receiving targeted therapies (63%, 95% CI 50%-76%; and 79%, 95% CI 68%-91%, respectively) vs fludarabine, cyclophosphamide, and rituximab or bendamustine and rituximab (FCR/BR; 37%,; 95% CI 26%-48%; and 70%, 95% CI 60%-81%, respectively) or chlorambucil+/−CD20-antibody (CD20Clb/Clb; 22%, 95% CI 10%-33%; and 60%, 95% CI 47%-74%, respectively). The grade ≥3 adverse event rate was similar with targeted treatment and FCR/BR.
Study details: This retrospective population-based real-world study included 286 patients with CLL who relapsed or were refractory to first-line treatment and received second-line targeted treatment (ibrutinib+venetoclax, venetoclax, venetoclax+rituximab/obinutuzumab, idelalisib, or idelalisib+rituximab), FCR/BR, or CD20Clb/Clb.
Disclosures: This study was partly supported by grants from Rigshospitalets Foundation. Some authors reported ties with various sources.

A 50-year-old White male presented with a 4- to 5-year history of progressively growing violaceous lesions on his left lower extremity
with scarce T-cells, classically presenting as rapidly progressive, plum-colored lesions on the lower extremities.1,2 CBCLs, with PCDLBCL-LT accounting for 4%, make up the minority of cutaneous lymphomas in the Western world.1-3 The leg type variant, typically demonstrating a female predominance and median age of onset in the 70s, is clinically aggressive and associated with a poorer prognosis, increased recurrence rate, and 40%-60% 5-year survival rate.1-5
Histologically, this variant demonstrates a diffuse sheet-like growth of enlarged atypical B-cells distinctively separated from the epidermis by a prominent grenz zone. Classic PCDLBCL-LT immunophenotype includes B-cell markers CD20 and IgM; triple expressor phenotype indicating c-MYC, BCL-2, and BCL-6 positivity; as well as CD10 negativity, lack of BCL-2 rearrangement, and presence of a positive MYD-88 molecular result.
Other characteristic histopathological findings include positivity for post-germinal markers IRF4/MUM-1 and FOXP-1, positivity for additional B-cell markers, including CD79 and PAX5, and negativity of t(14;18) (q32;21).1,3-5
This case is of significant interest as it falls within the approximately 10% of PCDLBCL-LT cases demonstrating weak to negative MUM-1 staining, in addition to its presentation in a younger male individual.
While MUM-1 positivity is common in this subtype, its presence, or lack thereof, should not be looked at in isolation when evaluating diagnostic criteria, nor has it been shown to have a statistically significant effect on survival rate – in contrast to factors like lesion location on the leg versus non-leg lesions, multiple lesions at diagnosis, and dissemination to other sites.2,6
PCDLBCL-LT can uncommonly present in non-leg locations and only 10% depict associated B-symptoms, such as fatigue, night sweats, weight loss, or lymphadenopathy.2,6 First-line treatment is with the R-CHOP chemotherapy regimen – consisting of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone – although radiotherapy is sometimes considered in patients with a single small lesion.1,2
Because of possible cutaneous involvement beyond the legs, common lack of systemic symptoms, and variable immunophenotypes, this case of MUM-1 negative PCDLBCL-LT highlights the importance of a clinicopathological approach to differentiate the subtypes of CBCLs, allowing for proper and individualized stratification of risk, prognosis, and treatment.
