To treat non-Hodgkin's B-cell lymphoma (B-NHL) in children with manageable toxicity-related morbidity and without any decrease in survival.


Between January 1998 and April 2003, 53 consecutive patients (age 16 years or less) from a single institution were enrolled. The patients were stratified by risk factors (stage and LDH level) and treated with a BFM 86/90 (Berlin-Frankfurt-Münster)-based protocol with reduction of the methotrexate dose from 5 mg/m to 2 mg/m.


The mean age of the patients was 6 years (range 1-16 years). Seventy-two percent of the patients had lymphomas classified as Burkitt type, 11% as diffuse large cell lymphoma, and 6% as Burkitt-like lymphoma, and 11% were not classified. At a median follow-up of 35 months, 44 patients (83%) survived in complete remission. The event-free survival rate for all patients was 78% (SE = 0.07): 100% (SE = 0.0) for stage I/II patients and 74% (SE = 0.08) for stage III/IV patients. Six patients suffered initial treatment failure and one patient relapsed, all of whom died. There was only one death from sepsis related to treatment.


This strategy was very effective for treating B-NHL in a developing country. The results were comparable to those of the BFM 90 study and other contemporary groups and represented an increase in the cure rates in childhood B-NHL in Brazil.
