OBJECTIVE: To present early clinical results of stereotactic conformal radiotherapy (SCRT) in patients with benign predominantly skull base meningiomas. MATERIAL AND METHODS: Between August 1994 and August 1999, 41 patients with benign residual or recurrent meningiomas were treated with SCRT. Thirty-three were histologically verified. All patients were immobilized in a GTC stereotactic relocatable frame, and underwent a post-contrast CT localization scan with additional MRI for fusion in 15 patients. Treatment was delivered on a 6MV linear accelerator using three (12 patients), or 4 (29 patients) non-coplanar conformal fixed fields to doses of 50–55Gy in 30–33 daily fractions. Tumours were relatively large with a median gross tumour volume (GTV) of 17.9cm³ (range 2.5–183cm³). RESULTS: At a median follow-up of 21 months (range 6–62 months) none of 41 patients have recurred.
