Abstract: BACKGROUND: Preoperative chemoradiotherapy (CRT) is one standard option for localized esophageal or gastroesophageal junction (GEJ) cancer patients but an optimal concurrent chemotherapy combination is not established. METHODS: 412 patients with resectable (cT1N1M0 or cT2-4N0-3M0) esophageal or GEJ cancer treated at the MDACC between October 2002 and June 2016 were analyzed. Exposures: CRT with DF or FOX followed by surgery (trimodality; TMT). Main outcomes and measures: Primary endpoints were overall survival (OS) and disease-free survival (DFS). Univariate and multivariate Cox analyses were performed. RESULTS: Of the 412 patients analyzed, 264 (64%) received DF and 148 (36%) FOX. The median age was 60 years, and 95% had adenocarcinoma. The clinical complete response, positron-emission tomography response, and pathologic complete response rates were 73%, 73%, and 30%, respectively. Median follow-up was 60.4 months. Median OS for the entire cohort was 81.6 months (95% confidence interval [CI], 56.3-122.0); 81.6 months (95% CI, 55.9-not estimable) for the DF group and 67.7 months (95% CI, 41.6-not estimable) for the FOX group (P = .24). The median DFS was 45.6 months (95% CI, 33.1-61.7) for the entire cohort; 49.5 months (95% CI, 38.6-70.3) for DF and 33.0 months (95% CI, 18.1-70.4; P = .38) for FOX. Higher tumor location (unfavorable) and clinical complete response (favorable) were prognostic for both OS and DFS in the multivariate analysis. CONCLUSION: At our high-volume center, the outcome of 412 TMT esophageal cancer patients was excellent. Taxane-based chemotherapy produces nonsignificant favorable trend.
