Chemo-radiotherapy and autologous bone marrow transplantation in poor prognosis neuroblastoma.

In Genoa, 39 patients affected by disseminated neuroblastoma, one to twelve years old, were treated with intensive chemotherapy (Vincristine 4 mg/sqm c.i. over 5 days, Melphalan 140 mg/sqm), total body irradiation (TBI) (3.3 Gy for 3 days), and unpurged autologous bone marrow transplantation (ABMT) since October 1984 until November 1987. Thirty-two patients were in complete response (first group) and 7 had residual disease (second group) after an intensive chemotherapeutic induction regimen. Actuarial overall survival at 38 months is 52% and disease free survival at 30 months is 28% for the first group. Actuarial overall survival at 25 months is instead 14% for the second group related treatment toxicity has not been too high (3 deaths).
