INTRODUCTION: Part B of the modified Magrath regimen (IVAC) +/- rituximab (R) is recommended as standalone therapy by national guidelines for management of relapsed/refractory Burkitt lymphoma, and is used in other non-Hodgkin lymphomas (NHL). Activity of IVAC in B-cell NHL, particularly with R, and its toxicity remain incompletely described.
PATIENTS AND METHODS: We reviewed patients with relapsed/refractory B-cell NHL treated with IVAC +/- R between 2004 and 2019 at Memorial Sloan Kettering Cancer Center to assess efficacy and toxicity.
RESULTS: Among 54 eligible patients (median 2 prior lines of therapy), 76% had diffuse large B-cell lymphoma; 30% had central nervous system involvement at IVAC initiation. Objective response rate was 48%. At median 22-month follow-up, median progression-free and overall survival were 3.1 months and 4.9 months, respectively. Grade ≥ 3 anemia (93%), neutropenia (94%), and thrombocytopenia (100%; all grade 4) were common. Febrile neutropenia occurred in 65% and did not appear to be influenced by use of antimicrobial or granulocyte colony stimulating factor prophylaxis. Mortality was attributed to treatment in 19% of evaluable patients.
CONCLUSION: The clinical efficacy and utility of IVAC +/- R remain unclear. However, its profound hematologic toxicity and life-threatening complications despite prophylactic measures warrant careful consideration of alternatives.
