Popis: BACKGROUND AND PURPOSE This study aimed to evaluate the efficacy of radical radiotherapy and assess prognostic factors in metachronous oligometastatic esophageal cancer (MOEC) patients after initial treatment with curative-intent surgery and/or chemoradiotherapy. MATERIALS AND METHODS MOEC Patients during 2009-2018 in Mianyang Central Hospital were retrospectively analyzed. Each patient had ≤5 oligometastatic lesions, and the primary lesions were controlled in this study. Patients were devided into radiotherapy (RT) and non-radiotherapy (NRT) groups. The study endpoints were overall survival (OS) and treatment toxicities. RESULTS This study included 82 patients who underwent intensity-modulated radiotherapy for MOEC. Median OS were 14 (95% confidence interval [CI], 11.0-17.0) and 7 (95% CI, 4.5-9.5) months for the RT and NRT groups, respectively (P = 0.016). Median OS were 18 (95% CI, 13.6-22.4) and 10 (95% CI, 5.1-14.9) months for lung and bone metastases, respectively (P = 0.010). Median OS were 15 (95% CI, 12.4-17.6) and 10 (95% CI, 7.6-12.4) months for interval time from initial diagnosis to metastasis ≥12 and
