Stereotactic body radiation therapy induces fast tumor control and symptom relief in patients with iliac lymph node metastasis

摘要: The CyberKnife is a robotic stereotactic body radiotherapy (SBRT) system which has shown promising results for many malignances with good efficacy and low toxicity. This study aims to evaluate the response local control (LC) obtained in management of iliac lymph node metastases (ILNM). Twenty-two patients 27 ILNM were treated by from May 2010 2016. Median follow-up time was 33 months (8–97). complete response, partial stable disease progression rates 37.0%, 48.0%, 7.5% respectively. 1-, 2-, 3-year LC all 90.6%, overall survival 78.8%, 60.6%, 43.3% All pelvic pain ureter obstruction achieved fast symptom relief, while leg edema persisted 2 patients. general treatment tolerance acceptable no severe toxicities reported. No factors found correlated failure. While (OS) better who had received total dose more than 30 Gy or prior systemic treatment, whose symptoms relieved. Taken together, an effective therapeutic option ILNM, providing high rate relief minimal
