Abstract | BACKGROUND: We analyzed the results of the LMB-89 protocol performed in seven centers in Venezuela in 96 children having B-cell non-Hodgkin lymphoma treated from 1995 to 2002. PROCEDURE: Mean age was 7.1 years with 71 (74%) been male. Eighty-two patients (85%) had diffuse small cell lymphoma Burkitt and Burkitt-like, and 14 (15%) had diffuse large B-cell lymphoma. Initial disease sites included the abdomen in 67%, peripheral nodes in 8%, and mediastinal in 4%. Treatment was directed to risk groups as described for LMB-89 protocol. Group A: seven patients (7%), group B: 80 patients (83%), and group C: nine patients (9%). RESULTS: Mean follow-up was 35 +/- 31 months. Complete remission (CR) occurred in 70 patients (73%); four patients (6%) had relapse during the first year and ten patients (10%) had progressive disease. Overall survival (OS) and event free survival (EFS) were 85 and 80% at 1 year, and 82 and 75% at 2 years, respectively. The EFS by therapeutic groups at 3 years was A: 100%; B: 76%, and C: 56%. TOXICITY: CONCLUSIONS: The high mortality rate during induction phase prohibited a better EFS. Prophylactic use of xantine- oxidase may improve future results. The high incidence of hepatitis B requires a vaccination program.
