Purpose To assess the treatment results of definitive radiotherapy for esophageal cancer at Tokushima University Hospital and clarify the prognostic factors. Methods Seventy consecutive patients with esophageal cancer who underwent definitive radiotherapy between May 2004 and March 2012 were included in the present study. Local control rate, overall survival rate, and radiation morbidity were examined and univariate and multivariate analyses were performed to investigate prognostic factors. Results The 5-yearoverall survival rates of stages I, II, III, and IVA were 81%, 71%, 0%, and 9%, respectively. Performance status, clinical stage, and neoadjuvant chemotherapy were significant prognostic factors. A past history of interstitial pneumonia was associated with severe radiation-induced lung injury. Conclusions Patients who underwent definitive chemoradiotherapy for esophageal cancer in stage I/II showed good prognosis. However, treatment results of the patients in stage III/IV were not satisfactory, and those who could not undergo surgery after neoadjuvant chemotherapy had the worst prognosis.J.Med.Invest.66:99-105, February, 2019.
