This treatment protocol was effective in improving ALL survival among patients at the authors' institute compared with previous trials, although the outcome remains lower than that in more industrialized countries. Prognostic factors defined in this study were similar to those identified by other cooperative groups.

This study confirms the high incidence of tumor necrosis and inflammation after chemotherapy for the abdominal Burkitt's lymphoma and consequently, the incidence of true-positive F-18 FDG studies is low. This necessitates the need for histopathological confirmation of positive studies.
