Procarbazine, CCNU and vincristine (PCV) combination chemotherapy for brain tumors.

12 patients with brain tumors were treated with a combination of procarbazine, CCNU (bis-2-chloroethyl-3-cyclohexyl-1-nitrosourea) and vincristine. 3 of 8 patients (37.5%) with primary brain tumors responded to chemotherapy, with a mean duration of 9.3 months. The mean survival of responders was 11.7 months, versus 3.6 months for nonresponders. 4 patients with metastatic brain tumors were also treated with the same combination chemotherapy; only 1, suffering from a lymphoma of the brain, responded partially.
