Abstract

BACKGROUND: To better counsel vestibular schwannoma patients, it is necessary to understand the tumor control rates of stereotactic radiosurgery (SRS).OBJECTIVES: To determine tumor control rates, factors determining control and complication rates following SRS.METHODS: Tertiary hospital retrospective cohort.RESULTS: 579 tumors (576 patients) were treated with SRS. 477 tumors (474 patients, 82%) had =1?year follow up and 60% (344) =3?years follow up. 88% of tumors had primary SRS and 6.7% salvage SRS. Median follow up time was 4.6?years. At 3?years, the tumor control rate of primary SRS was 89% (258 of 290) in sporadic tumors compared to 43% in Neurofibromatosis type II (3 of 17) (p?
