Stereotactic Radiosurgery in Pituitary Adenomas: A Single Center Experience
2012
The aim of this study was to evaluate the efficiency of stereotactic radiosurgery (SRS) in the management of pituitary ade- nomas. Between June 1998 and July 2011, 57 patients with pituitary adenomas were treated using SRS at our department. All patients underwent high-precision single dose SRS using a linear accelerator with 6-MV photons. Median follow-up time was 31.5 (3-92) months. Median age was 40 years (range: 19-57 years). Radiological tumor growth control was achieved in 48 patients (84.2%) (a decrease in tumor size in 25 patients and no change in tumor size in 23 patients). 13 patients with functioning adenomas had available biochemical follow-up and biochemical complete response was achieved in 8 (61.5%) of these 13 patients. Treatment of pituitary adenomas using LINAC-based single dose SRS is safe and effective in impro- ving local tumor and biochemical control.
