Ann Surg Oncol 2021 May 9. Epub 2021 May 9.

Department of Radiation Oncology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Objective: The aim of this study was to compare the prognostic predictive power of the 11th Japan Esophageal Society (JES) staging system with the 8th edition of the American Joint Committee on Cancer (AJCC) staging system in patients with thoracic esophageal squamous cell carcinoma (TESCC), and to estimate the survival benefits of postoperative radiotherapy (PORT) based on a substage of the JES staging system.

Methods: Area under the curve (AUC) values of the receiver operating characteristic curve were calculated to evaluate prognostic efficacy. Propensity score matching (PSM) analysis was conducted to balance the two groups (surgery only [S group] or surgery plus PORT [S+RT group]) across substages of the 11th JES staging system according to independent prognostic factors for overall survival (OS) identified using Cox proportional hazards regression.
