title: Treatment of recurrent malignant supratentorial gliomas with the association of procarbazine, thiotepa and vincristine: a phase II study.
abstract: Twenty patients previously treated with surgery, radiation therapy and chemotherapy with a nitrosourea for malignant supratentorial gliomas received a combination of procarbazine, thiotepa and vincristine (P.T.V.) at tumor recurrence. Procarbazine was given at a dose of 100 mg/m2 per os from day 1 (D1) to day 15 (D15), thiotepa was administered i.v. at a dose of 35-45 mg/m2 at D1, and vincristine at a dose of 1.4 mg/m2 at D1 and D8. Courses of therapy were repeated every four weeks. Tolerance was evaluated in 20 patients. Three patients developed peripheral neuropathy after 2 or 3 courses of vincristine which was then discontinued. Blood toxicity over grade I occurred in 8 patients (40%). One patient developed a grade i.v. pancytopenia. All 20 patients could be evaluated for therapeutic response. A partial response was noted in 3 patients (15%): 1 glioblastoma multiforme, 1 anaplastic oligodendroglioma and 1 anaplastic astrocytoma. In these three patients time to tumor progression was 10, 11+ and 5 months, respectively. Stabilization lasting 4 months was observed in one patient (anaplastic astrocytoma). Estimated median duration of survival for the entire group was 4.5 months following the onset of PTV (13 months following the date of histology).
