RESUMO
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 (Pâ=â.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; Pâ=â.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.

What are standards? The oncology community expends considerable effort to review the results from definitive treatment studies and define recommendations for future studies, as well as standards of care for the community and patients who are not participating in clinical trials. This is a thoughtful and well-intentioned process but subject to considerable bias due to limitations in the data and/or their interpretation. While ovarian cancer is highly responsive to platinum-based therapy after initial cytoreductive surgery, there is a substantial risk of recurrence, which is accompanied by the emergence of drug-resistant disease. Better treatments with improved long-term outcomes are needed. From this perspective, standards can help to provide a baseline for assessing gaps in our current knowledge and defining priorities for future clinical trials. While not an exhaustive review, this study will focus on key clinical concepts that are guiding ovarian cancer research and treatment.
