Chemotherapy as an adjunct in the initial management of cerebellar medulloblastomas. A preliminary report.

Eight consecutive children with biopsy-proven cerebellar medulloblastoma were treated with a combination of whole neuraxis radiation and prolonged chemotherapy using vincristine and cyclophosphamide. There was no evidence of tumor recurrence in the follow-up period, which ranged from 16 months to 7 years and 8 months following diagnosis. Morbidity associated with this regimen has been infrequent and easily reversible.
