Treatment outcomes of adult Burkitt lymphoma: results with a modified LMB protocol in Brazil and feasibility of outpatient administration.

While Burkitt lymphoma (BL) is an aggressive subtype of non-Hodgkin lymphoma more prevalent in tropical areas, few studies on BL have been conducted in Latin America. Here, we evaluate the clinical presentation and outcomes of an adapted LMB regimen for adults with sporadic BL. We retrospectively evaluated hospital records from University of São Paulo (USP) between 1999 and 2017. Thirty-six patients were included, the median age was 33.5 years and 69% (25) were male. Most patients presented advanced stage disease (81%), 8% had CNS disease, and the majority belonged to LMB group B (75% (27)). Three patients died during the induction phase, and the remaining patients (33) achieved complete response. There was one relapse over a median follow-up of 6 years. Overall survival estimated at 5 years was 89%. We conclude that an adapted LMB protocol is safe and feasible in Brazil.
