Article Synopsis
  • Vitreoretinal lymphoma (VRL) has a poor prognosis due to high relapse rates in the central nervous system, requiring treatments like high-dose chemotherapy with autologous stem cell transplantation (HCT-ASCT).
  • A study analyzed 38 adult patients treated with HCT-ASCT for isolated VRL over 11 years, showing that 84% received a thiotepa-based regimen, with some patients experiencing serious side effects.
  • Results revealed a significant relapse rate, particularly in the brain, but the strategy showed relatively good median survival rates: 96 months for progression-free survival and 92 months overall.

Marginal Zone Lymphoma (MZL) comprises three subtypes: extranodal MZL (EMZL), splenic MZL (SMZL) and nodal MZL (NMZL). Since clinical trials have limited representativeness, there is a need for real-world data (RWD) evidence in MZL. Real-world data in Lymphoma and survival in Adults (REALYSA) is a prospective multicentric French cohort of newly diagnosed lymphoma patients.

Article Synopsis
  • Autologous anti-CD19 CAR T cells are becoming standard treatment for relapsed/refractory large B-cell lymphoma, but serious side effects like cytokine release syndrome (CRS) and neurotoxicity (ICANS) pose risks, often requiring ICU care.
  • In a study involving 925 patients in France, high rates of CRS (84.1%) and ICANS (40.5%) were observed, with significant proportions experiencing severe forms of these conditions.
  • Two prognostic scoring systems (CRS-PSS and ICANS-PSS) were developed to identify patients at higher risk for severe CRS and ICANS based on specific clinical factors, and these scores were validated in other patient groups treated with similar therapies.

Article Synopsis
  • The study investigates the role of the cerebellum-to-liver uptake ratio (CLIP) as a prognostic factor for patients with post-transplant lymphoproliferative disorders (PTLD), in addition to the International Prognostic Index (IPI) score.
  • A total of 97 PTLD patients were analyzed, revealing that both a higher IPI score (≥ 3) and lower CLIP (< 3.24) correlated with poorer progression-free survival (PFS) outcomes.
  • While CLIP shows potential as a predictor for PFS, its association with overall survival (OS) was not statistically significant, indicating that further research is needed to validate these findings.

Immunotherapy (IT) is a major therapeutic strategy for lymphoma, significantly improving patient prognosis. IT remains ineffective for a significant number of patients, however, and exposes them to specific toxicities. The identification predictive factors around efficacy and toxicity would allow better targeting of patients with a higher ratio of benefit to risk.

Patients (pts) with asymptomatic low-burden follicular lymphoma (FL) are usually observed at diagnosis. Time to lymphoma treatment (TLT) initiation can however be very heterogeneous and risk factors of progression are poorly studied. Our study evaluated 201 pts with grade 1-3a low-tumor burden FL diagnosed in four French centers between 2010 and 2020 and managed by a watch and wait strategy in real-life settings.

Primary central nervous system lymphomas (PCNSLs) classically remain confined within the CNS throughout their evolution for unknown reasons. Our objective was to analyse the rare extracerebral relapses of PCNSL in a nationwide population-based study. We retrospectively selected PCNSL patients who experienced extracerebral relapse during their follow-up from the French LOC database.

Post-transplant lymphoproliferative disorder (PTLD) is a rare complication of immunosuppression. Sequential treatment is commonly proposed, combining induction with rituximab (R-induction) followed by either continuation of treatment or addition of chemotherapy depending on response. Response to R-induction, often assessed by CT scan, is a major predictor of overall survival (OS).

Article Synopsis
  • About 10-30% of adults with primary mediastinal B cell lymphoma (PMBCL) either don't respond to treatment or relapse early, making allogeneic stem cell transplantation (allo-HSCT) a potential curative option.
  • A study examined 33 PMBCL patients who underwent allo-HSCT between 1999 and 2018, revealing that 42% had sibling donors and that patients had varying responses to prior treatments.
  • The findings reported a 2-year overall survival rate of 48% and suggested that the disease status at the time of transplant significantly affected survival outcomes, with a possibility of durable remissions after 4 years for some patients.

Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) have both demonstrated impressive clinical activity in relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). In this study, we analyzed the outcome of 809 patients with R/R DLBCL after two or more previous lines of treatment who had a commercial chimeric antigen receptor (CAR) T cells order for axi-cel or tisa-cel and were registered in the retrospective French DESCAR-T registry study ( NCT04328298 ). After 1:1 propensity score matching (n = 418), the best overall response rate/complete response rate (ORR/CRR) was 80%/60% versus 66%/42% for patients treated with axi-cel compared to tisa-cel, respectively (P < 0.
