Progression or relapse in the central nervous system (CNS) remains a rare but mostly fatal event for patients with diffuse large B-cell lymphoma (DLBCL). In a retrospective analysis of 5189 patients treated within 19 prospective German and French phase 2/3 trials, we identified 159 patients experiencing a CNS event (relapse: 62%, progression: 38%). Intracerebral, meningeal, intraspinal, or combined involvement was reported in 44%, 31%, 3%, and 22% of patients, respectively.

Article Synopsis
  • Real-world data (RWD) are crucial for enhancing clinical trial (CT) findings, but challenges like data quality persist; the REALYSA study, launched in 2018, focuses on newly diagnosed lymphoma patients in France.
  • A proof-of-concept analysis of 645 patients with diffuse large B-cell lymphoma (DLBCL) found high data completeness (<4% missing) and revealed good survival rates, with a median follow-up of 9.9 months showing 1-year event-free survival of 77.9% and overall survival of 90.0%.
  • The study also assessed how well REALYSA's patient outcomes matched those from recent phase 3 trials (POLARIX and SENIOR), demonstrating

  • Rituximab treatment is more effective than the 'watch and wait' approach for low-tumor burden follicular lymphoma, improving progression-free survival (PFS) but maintenance therapy raised concerns about resource use and patient adherence.
  • A study compared intravenous (IV) rituximab and subcutaneous (SC) rituximab adminstration in patients, demonstrating better 4-year PFS rates in the experimental SC group (58.1% vs 41.2%).
  • While high exposure to rituximab during the first three months led to improved response rates, time to next treatment (TTNT) and overall survival (OS) showed no significant differences between the two approaches.

Most patients with diffuse large B-cell lymphoma (DLBCL) can be cured with immunochemotherapy such as R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). Patients with progression or relapse in the central nervous system (CNS) face dismal outcomes. The impact of more aggressive regimens used in frontline therapy has not been systematically investigated in this context.

Article Synopsis
  • - The study aimed to assess the accuracy of a second FDG-PET/CT scan in evaluating patients with localized muscle-invasive bladder cancer after receiving neoadjuvant chemotherapy before radical cystectomy.
  • - A total of 62 patients were reviewed, and after exclusions, 45 patients were analyzed, with FDG-PET/CT showing a sensitivity of over 95% but lower specificity in identifying complete responders and residual disease compared to histopathology.
  • - The findings indicate that FDG-PET/CT can effectively identify patients who may need alternative treatment avenues if they do not respond completely to chemotherapy.

The LNH03-6B trial was a phase 3 randomized trial evaluating the efficacy of first-line rituximab, cyclophosphamide, doxorubicine, vincristine and prednisone (R-CHOP) delivered every 2 weeks (R-CHOP14) or 3 weeks (R-CHOP21) in patients with diffuse large B-cell lymphoma (DLBCL) aged 60 to 80 years with an aaIPI (age-adjusted International Prognostic Index) score ≥1 (registered as NCT00144755). We implemented a prospective long-term follow-up program at the end of this trial. The primary endpoints were progression-free survival (PFS) and overall survival (OS).

Background: Age-adjusted lymphoma incidence rates continue to rise in France since the early 80's, although rates have slowed since 2010 and vary across subtypes. Recent improvements in patient survival in major lymphoma subtypes at population level raise new questions about patient outcomes (i.e.

Article Synopsis
  • Early identification of high-risk diffuse large B-cell lymphoma (DLBCL) patients is crucial for tailoring innovative treatments, as higher total metabolic tumor volume (TMTV) at baseline is linked to poorer survival outcomes.
  • In a study analyzing patients aged 60-80 from the phase 3 REMARC trial, a TMTV cutoff of 220 cm³ was determined to aid in predicting progression-free survival (PFS) and overall survival (OS).
  • The findings highlight that high TMTV, along with a poor Eastern Cooperative Oncology Group performance status (ECOG PS), can help identify an ultra-risk group, suggesting the need for more aggressive treatment strategies even after initial successful therapy with R-CHOP.

Lenalidomide maintenance therapy prolonged progression-free survival (PFS) versus placebo in elderly patients with diffuse large B-cell lymphoma (DLBCL) responding to induction chemotherapy in the phase 3 REMARC study. This subpopulation analysis assessed the impact of lenalidomide maintenance and treatment-emergent adverse events (TEAEs) on health-related quality of life (HRQOL). Global health status (GHS), and physical functioning and fatigue subscales were evaluated in patients who completed the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire-C30 v3.

Purpose: Carfilzomib is a novel generation proteasome inhibitor. The Carmysap trial demonstrated that twice-weekly KMP (carfilzomib, melphalan, prednisone) might challenge the MPV (melphalan, prednisone, bortezomib) standard. We sought to study KMP weekly, allowing to increase carfilzomib's dose with maintained efficacy and improved safety profile.

Purpose Selection bias in clinical trials has consequences for scientific validity and applicability of study results to the general population. There is concern that patients with clinically aggressive disease may not have enrolled in recent diffuse large B-cell lymphoma (DLBCL) trials due to the consent process and the inability to delay therapy for eligibility evaluation. We have examined the diagnosis-to-treatment interval (DTI) and its association with clinical factors and outcome in a clinic-based observational cohort of patients with DLBCL from the United States.

In follicular lymphoma (FL), no prognostic index has been built based solely on a cohort of patients treated with initial immunochemotherapy. There is currently a need to define parsimonious clinical models for trial stratification and to add on biomolecular factors. Here, we confirmed the validity of both the follicular lymphoma international prognostic index (FLIPI) and the FLIPI2 in the large prospective PRIMA trial cohort of 1135 patients treated with initial R-chemotherapy ± R maintenance.

CNS relapse is reported in 2-5% of diffuse large B-cell lymphoma (DLBCL) patients, dramatically decreasing overall survival (OS). Very few studies address incidence and risk factors of CNS relapse in very elderly patients, a challenging population to treat given their commonly associated comorbidities. A retrospective analysis was performed of 270 DLBCL patients >80 years treated between 2004 and 2013 in two multicentre phase II LYSA trials (LNH03-7B, LNH09-7B) evaluating the addition of rituximab or ofatumumab to mini-CHOP as front-line therapy.

Background: In 2011 we reported a rituximab plus miniCHOP (reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone) combination for patients older than 80 years with diffuse large B-cell lymphoma (DLBCL). The 2-year overall survival was 59% (95% CI 49-67) with an excess of early toxicity. To improve those results we tested the same chemotherapy protocol in combination with ofatumumab and a pre-phase treatment.

Guidelines for monitoring multiple myeloma (MM) patients expressing light chains only (light-chain MM [LCMM]) rely on measurements of monoclonal protein in urine. Alternatively, serum free light chain (sFLC) measurements have better sensitivity over urine methods, however, demonstration that improved sensitivity provides any clinical benefit is lacking. Here, we compared performance of serum and urine measurements in 113 (72κ, 41λ) newly diagnosed LCMM patients enrolled in the Intergroupe Francophone du Myélome (IFM) 2009 trial.

Single nucleotide polymorphisms (SNPs) in FCγ-receptor genes FCGR3A (rs396991) and FCGR2A (rs1801274) influence the affinity of the Fc portion of anti-CD20 immunoglobulin G1 monoclonal antibody. Their roles in diffuse large B-cell lymphoma (DLBCL) treated with rituximab in combination with anthracycline-based chemotherapy remain controversial. To address this question, we genotyped FCGR2A and FCGR3A SNPs in two prospective DLBCL cohorts from Lymphoma Study Association trials (N = 554) and Iowa/Mayo Specialized Program Of Research Excellence (N = 580).

Article Synopsis
  • Initial concerns were raised about statin use in lymphoma due to laboratory data suggesting it might hinder anti-CD20 antibody effectiveness, but later studies indicated potential benefits, particularly in follicular lymphoma patients.
  • This study analyzed data from the PRIMA trial, focusing on 1,135 follicular lymphoma patients, with 10.5% of them using statins at diagnosis to evaluate their impact on treatment outcomes.
  • Results showed no significant differences in event-free survival, time to next treatment, or overall survival between patients using statins and those who weren't, indicating that statin use does not affect prognosis in this group.

Therapeutical options for older multiple myeloma patients have been improved with the advent of new drugs, yet there is a lack of observational data for such patients. To address this issue, an age-stratified analysis of the VESUVE cohort of bortezomib users was performed. Among the 779 patients included in the analysis, 358 (46%) were aged ≤ 65 years, 282 (36%) were between 65-75 years and 139 (18%) were more than 75 years old.
