The present study reports the outcomes of patients with brain metastasis from gynecological malignancies who were treated with stereotactic radiosurgery (SRS). Patients with brain metastasis from a gynecological primary site were treated with SRS using the Cyberknife™ frameless SRS system. Primary lesions were treated with a single frac- tion of 16-22 Gy. A total of 3 resection cavities were treated with 8 Gy 3 times, meaning a total of 24 Gy, and 1 recurrent lesion was reirradiated with 5 Gy 5 times, meaning a total of 25 Gy. All patients were followed up with regular magnetic resonance imaging and clinical examinations 1 month after treatment and every 2 months thereafter. A total of 20 lesions in 8 patients were included in this study; 1 patient presented with metastatic endometrial cancer and the remaining 7 presented with metastatic ovarian cancer. The median age was 61 years (range, 48-78 years). All patients had received systemic therapy prior to developing brain metastasis. A total of 3 patients underwent surgical resection and 1 patient was administered re-irradiation for recurrence. There were 3 local failures in 2 patients. The actuarial 1-, 2-and 3-year local control rates were 91, 91 and 76%, respectively. The median overall survival time was 29 months. No SRS-associated toxicities or neurological mortalities were observed. In conclusion, brain metastasis from gynecological malignancies is uncommon, however, SRS is a safe and effective treatment modality for local control as a primary or adjuvant treatment in patients with this disease.
