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.

To assess the tolerability of Cyberknife Radiosurgery for High Grade Gliomas in Elderly with poor performance status.


Assessment of local control rate, progression free survival, overall survival, quality of life and toxicity and steroid dependence in this population with this regime.
