The present study aimed to determine the factors associated with early recurrence and cancer death for patients with ESCC treated by trimodal therapy. Patients and Methods: We evaluated risk factors for recurrence within 6 months, as well as cancer death within 1 year based on data from 141 patients with ESCC who underwent NCRT followed by curative esophagectomy. Results: The carcinoembryonic antigen level before treatment, postoperative complications, pathology after neo-adjuvant therapy (ypT, ypN), lymphatic invasion, venous invasion and pathological response of the primary tumor were significant factors in a comparison of patients with and without early recurrence. Multivariate analysis subsequently selected ypN [ypN, 0/1 vs. 2/3; hazard ratio (HR)=4.13, 95% confidence interval (CI)=1.25-13.66; p=0.02] as an independent covariate for early recurrence. Postoperative complications, ypT, ypN, poorer tumor differentiation, lymphatic invasion and venous invasion were significant factors in a comparison of patients with and without early cancer death. Multivariate analysis subsequently selected postoperative complications of grade ≥3b (vs. <3b) defined according to the Clavien–Dindo classification (HR=5.9, 95% CI=1.53-23.47; p=0.01) and venous invasion (vs. without: HR=4.80, 95% CI=1.21-19.14; p=0.03) as independent covariates for early cancer death. Conclusion: Further reduction of postoperative complications are needed after NCRT for patients with ESCC. Meticulous surveillance and postoperative adjuvant therapy should be considered for patients with risk factors for early recurrence and cancer death. ER -
