title: The results of a randomised trial of mixed-schedule (neutron/photon) irradiation in the treatment of supratentorial Grade III and Grade IV astrocytoma.
abstract: A randomised trial is reported of mixed-schedule (neutron/photon) irradiation compared with photon therapy for patients with Grade III or Grade IV astrocytoma. Thirty-one patients were allocated to be treated by the neutron/photon regime and 30 patients by photons. The median survival was 4 months in the mixed-schedule group and 8 months in the photon group. The survival rates were not significantly different. All patients who died had evidence of residual brain tumour. None had signs of radiation-related morbidity.
