Highly effective induction therapy for stage 4 neuroblastoma in children over 1 year of age.
1994
PURPOSETo test the efficacy of a protocol for poor-risk neuroblastoma that builds on the following: (1) our favorable previously reported results with dose-intensive use of cyclophosphamide; (2) our retrospective analysis of neuroblastoma chemotherapy reports, which supported the value of high-dose cisplatin and etoposide (VP-16); and (3) the Goldie-Coldman hypothesis that rapid cytoreduction plus the use of non-cross-resistant chemotherapy combinations will decrease the risk of drug resistance.PATIENTS AND METHODSThe N6 protocol included seven courses of high-dose chemotherapy plus surgical resection of bulk disease. Courses 1, 2, 4, and 6 consisted of 6-hour intravenous infusions of cyclophosphamide 70 mg/kg/d on days 1 and 2 (ie, 140 mg/kg per course), a 72-hour intravenous infusion of doxorubicin 75 mg/m2 and vincristine 0.1 mg/kg beginning day 1, and vincristine 1.5 mg/m2 intravenous bolus on day 9. Courses 3, 5, and 7 consisted of 2-hour intravenous infusions of VP-16 200 mg/m2/d on days 1 to 3 (ie,...
