First-line treatment with Bendamustine plus Rituximab for patients with indolent non-Hodgkin’s lymphoma or Mantle cell lymphoma: Real-world experience.
Notice bibliographique
Résumé
e19540 Background: Bendamustine plus rituximab (B+R) was established as a preferred first line therapy for patients with previously untreated indolent non-Hodgkin’s lymphoma based on the BRIGHT and STIL trials. However, only few reports on efficacy and safety data of this combination in the real-world setting are available to-date. Methods: We conducted a retrospective review of patients who received therapy with standard doses of B+R in our cancer center from June 2013 to January 2021. Patients with indolent non-Hodgkin’s lymphoma (iNHL) and mantle cell lymphoma (MCL) who received more than one cycle of B+R were evaluated. Results: Amongst a total of 201 patients 56% were males and 44% females. Median age at B+R initiation was 72 years (range 34-94). Follicular lymphoma (FL) (50.3%), marginal zone lymphoma (MZL) (19.4%), and lymphoplasmacytic lymphoma (LPL) (14.5%) were the most common iNHL. Stage 3 and 4 diseases represented 19.9% and 68.6% of patients. Extranodal disease was found in 35.8%. The proportion of patients with high risk disease was 48.5% for FL (FLIPI ≥3), 86.6% for LPL (WMISS score ≥2), and 80.5% for MCL (MIPI score ≥6.2). Prior history of secondary malignancy had 23.4% of patients; 11.4% patients had ECOG 3. Most common indications for B+R initiation were bulky symptomatic lymphadenopathy (69.1%), cytopenia (36.8%) and constitutional symptoms (36.8%). Fifty-eight percent of patients had more than one indication for therapy. Median number of B+R cycles delivered was 6 (range: 1-6), median dose of bendamustine was 90 mg/m2 (range 45-90). Full doses of treatment were given in 66.7% of patients, reduced in 33.3% with mean dose 78.3 mg/m2. A total of 50.8% completed 6 cycles with no delays, in 49.2% treatment was delayed (mean delay time 1.8 weeks). Overall response was 94.5%, with 77.6% complete and 16.9% partial remission. Median duration of follow-up was 35 months (range: 4-91). At the end of follow-up, event free survival (EFS) was 77.1% and overall survival (OS) was 79.6%. Six percent of patients relapsed, 8% developed secondary hematological malignancies, including 14 cases of aggressive B-cell lymphoma and 2 cases of MDS. 16.9% of patients required support with G-CSF. Grade 3-4 neutropenia was recorded in 22.4%, febrile neutropenia in 7.5%, grade 3-4 anemia in 7.9%, and grade 3-4 thrombocytopenia in 3.9% of patients. Rituximab-associated infusion reactions, skin rash, thrombophlebitis, and infection were the most common non-hematological adverse events. A total of 80.6% of patients proceeded to rituximab maintenance. Conclusions: B+R chemoimmunotherapy is feasible to administer in non-clinical trial setting. Despite more dose reduction as compared to STIL trial, B+R retained its efficacy with comparable EFS and OS. No new adverse events or increase in secondary malignancies were found.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
