Abstract：Objective To retrospectively analyze the factors of postoperative recurrence of stage pT1-3N0M0 esophageal squamous cell carcinoma. Methods A total of 488 patients who underwent two-field R0 esophagectomy, pathologically classified as stage pT1-3N0M0, without adjuvant radiotherapy and/or chemotherapy before or after surgery and postoperative survival time≥ 3 months were enrolled in this study. Multivariate analysis was performed by using Cox model. Results At the end of follow-up, the overall recurrence rate was 36.9%(180/488);the local recurrence rate was 21.5%(105/488), the distant metastasis rate was 6.8%(33/488) and the local recurrence rate complicated with the distant metastasis rate was 8.6%(42/488).Cox multivariate analysis demonstrated that tumor site and pT staging were the factors affecting the overall/local recurrence rate and distant metastasis. The recurrence rate in patients with the upper esophageal squamous cell carcinoma and stage pT3 was the highest, followed by those with the middle esophageal squamous cell carcinoma or stage pT2 and the lowest recurrence rate was observed in patients with the lower esophageal squamous cell carcinoma or stage pT1. Conclusions Tumor site and pT staging are the pivotal factors for postoperative recurrence of stage pT1-3N0M0 esophageal squamous cell carcinoma after two-field R0 esophagectomy, which contributes to offer guidance to the selection of indications for postoperative adjuvant radiotherapy.
