title: Salvage chemotherapy for recurrent primary brain tumors in children.
abstract: Sixty consecutive evaluable children with recurrent primary tumors of the central nervous system were treated with a regimen of vincristine, nitrogen mustard, procarbazine, and prednisone over a 12-year period. Tumor types included medulloblastoma (19), brain-stem glioma (16), astrocytoma (13), and a miscellaneous glioma (12). Responses and sustained survivals were achieved. Responses were highly dependent on tumor type. Disease progression was halted in 73% of the children with medulloblastoma, and three have survived in complete remission for more than 10 years from the start of therapy with vincristine, nitrogen mustard, procarbazine, and prednisone. Two of four patients with anaplastic glioma, are long-term survivors. In contrast, less than one third of children with brain-stem gliomas responded. Toxicity consisted mainly of neutropenia, thrombocytopenia, infections, and rarely a procarbazine rash.
