Advanced neuroblastoma: results of two treatment programs including sequential hemibody irradiation.
Results of two consecutive treatment programs for advanced neuroblastoma, including sequential hemibody irradiation, are analyzed and compared. The first treatment program (I-TP) included one single-fraction (7 Gy) irradiation to the upper and lower halves of the body as consolidation of remission achieved by previous chemotherapy with CDDP and VP16. A fractionated technique (2 Gy daily for 4 consecutive days to each hemibody) was used in the second treatment program (II-TP) for children in remission following a combination of CDDP + VP16 and ADM + VCR + CTX. In both treatment programs, chemotherapy was continued according to the same pre-radiation regimen following the two sessions of hemibody irradiation. Overall response rate to pre-radiation chemotherapy was 84% and 60% for I-TP and II-TP, respectively. Thirty-month overall progression-free survival was 0 for I-TP and 20% for II-TP. No treatment-related fatalities occurred. In the subsets of patients who reached complete or good partial remission during the pre-radiation chemotherapeutic phase, 30-month progression-free survival in I-TP and II-TP was 0 and 33%, respectively. The role of fractionated hemibody irradiation in prolonging the progression-free survival can be inferred.
