Work in progress: 252Cf neutron brachytherapy for hemispheric malignant glioma.

Abstract
252Cf neutron brachytherapy of human hemispheric malignant glioma can be readily carried out and may be combined with external, whole brain photon beam therapy of 6000 rad (60 Gy [Grays]) administered over a 5 wk-7wk period. The 10 patients who were studied tolerated both procedures well. There was improvement in performance status, and a decrease in tumor size was observed upon computed tomographic scanning.
