Abstract
PURPOSE This study evaluates the role and outcomes of Gamma Knife radiosurgery (GKRS) in the management of pituitary metastases. METHODS The records of brain metastases patients who underwent GKRS at the University of Pittsburgh Medical Center during the 10-year interval of 2010-2020 were systematically reviewed. Outcome measures included patient survival, tumor control rate, pituitary hormonal outcomes, visual outcomes, adverse radiation effects (AREs), and need for adjuvant therapy. RESULTS Eighteen patients with pituitary metastases (eight male; median age of 65.5 years) had sufficient clinical follow-up for analysis. The most common primary cancers were non-small cell lung cancer (n = 6) and breast cancer (n = 4). Patients presented with headache (n = 9) and visual difficulties (n = 6). One patient underwent resection before GKRS. The median tumor volume was 0.78 cc (range 0.04-6.42 cc). The median overall survival after GKRS was 6.5 months (range 0.5-58 months). The overall survival after GKRS at 3-, 6-, and 12-months were 72.2%, 50.0% and 38.9%, respectively. The tumor control rate was 94.4%. One patient had further progression that required additional GKRS. None of the patients developed AREs after GKRS. CONCLUSION GKRS is an effective treatment modality for the multidisciplinary management of patients with pituitary metastases. This minimally-invasive strategy is associated with optimal tumor control rate and low risk to adjacent optic nerves or neurovascular structures.
