Abstract:
BACKGROUND AND OBJECTIVE:After the good results obtained by the Société Française d'Oncologie Pédiatrique (SFOP) regarding the pediatric B-type non-Hodgkin's (Burkitt and large B-cell) lymphoma and L3 leukemia, the Sociedad Española de Hematología y Oncología Pediátricas (SHOP) decided to use the same treatment protocol. PATIENTS AND METHOD:Pediatric patients diagnosed with B-type non-Hodgkin's lymphoma without a previous history of malignant diseases were eligible for this study. They were classified in 3 groups of risk: group A (resected stage I and abdominal stage II), group B (not eligible for groups A or C), and group C (with central nervous system involvement and L3 leukemia). All received treatment according to the SFOP's LMB89 protocol. RESULTS:A total of 153 patients were considered in this multicenter, prospective and non-randomized trial (1997-2005). The global and event-free survival (EFS) were found to be of 88% (0.88; 95% confidence interval [CI], 0.83-0.93) and 85% (0.85; 95% CI, 0.79-0.90), respectively. The EFS was 100% for the group A (n = 16), 86% (0.86; 95% CI, 0.79-0.92) for the group B (n = 113), and 68% (0.68; 95% CI, 0.49-0.86) for the group C (n = 24). CONCLUSIONS:The results confirm the good efficiency of the LMB89 protocol for treating B-cell lymphoma and L3 leukemia, despite having diminished the treatment intensity in the less risk groups. The worst prognostic factor was found to be a central nervous system involvement, whereas being younger than 10 years was confirmed to be a favorable prognostic factor. In addition, no differences were evidenced between Burkitt and large B-cell lymphoma.
