VINCRISTINE sulfate, an alkaloid of the periwinkle plant, was made available for clinical use in 1961. Early data suggested activity of this drug in the treatment of children with acute leukemia1-3 and a variety of solid tumors.4-6 In children with generalized neuroblastoma, one of three reported by Selawry and Hananian4 and three of seven children studied by James and George5 demonstrated favorable tumor response to vincristine. The effectiveness of vincristine in children with generalized neuroblastoma was investigated by a co-operative protocol study of the Pediatric Division of the Southwest Cancer Chemotherapy Study Group. The results of this study constitute the basis for this preliminary report.
