Radiosurgery for Glioblastoma Multiforme

Conventional radiation for 6 weeks is not well tolerated by the elderly. Shorter courses (over 3-5 weeks) of radiation have been shown to be equivalent in outcome the elderly- particularly in patients who are generally in poor performance status (KPS<70). Fractionated Cyberknife Radiosurgery can deliver equivalent doses in 5 treatments providing the same tumor control in a much shorter and tolerable schedule improving their quality of their short life.
