An intraoperative remote afterloading endocurietherapy technique with 
high-activity 60Co for the treatment of glioblastoma multiforme is described. 
The technique can be used for initial management of the unresectable tumor or 
for retreatment of patients with recurrent tumor who have been treated 
previously with surgery and postoperative radiotherapy. Neither intraoperative 
nor postoperative complications were encountered in our treatment of 11 patients 
in this Phase I toxicity study.
