[Association of 5-FU, CDDP and hypofractionated radiotherapy in recurrences of subtentorial astrocytomas and malignant gliomas in adults].

Twenty-seven patients who had a relapse of astrocytomas or supra-tentorial malignant gliomas, previously treated by radio-surgical combination or exclusive irradiation, underwent a combination of 3 courses of 5-FU, cis-platyl and hypofractionated irradiation. No objective response was observed, but there was a progression of the tumor in 33% of the cases, and no change in 67%. Overall median survival was 7 +/- 1.5 months. The 20 patients with grade III or IV astrocytomas had a lower median rate than the 7 patients with grade II astrocytomas or oligodendrogliomas: 6 +/- 1.8 months versus 18 +/- 3.2 (P = 0.16). Median survival was 14 +/- 2.7 months for neurological responders and 6 +/- 2.1 months for non-responders (P = 0.017).
