	abstract = {Background: Patients treated with neoadjuvant chemoradiotherapy (NAC) followed by esophagectomy are more likely to have negative margins at resection, be downstaged, and have improved overall survival (OS). The specific aim of this study was to analyze OS outcomes using NAC followed by esophagectomy at a single, tertiary care academic medical center. 
Methods: We retrospectively analyzed 106 patients that underwent NAC with platinum-based chemotherapy plus 5-fluorouracil (5-FU) or capecitabine followed by esophagectomy from September 1996 to May 2011. OS was analyzed by the Kaplan Meier method. 
Results: Initial staging determined that of 106 patients, 62% had stage III (n=66), 31% stage II (n=33), and 7% had stage I disease (n=7). Following NAC, 92.5% (n=98) were resected with negative (R0) margins and pathologic staging revealed 59% (n=62) were downstaged, 9% (n=10) were upstaged, and 32% (n=34) remained at the same stage. A pathologic complete response (pCR) was achieved in 29% (n=31) of the cohort. Median OS was 35.2 months for all patients, 42 months for downstaged patients, 13 months when upstaged, and 17 months for those who remained at the same stage (P=0.08). OS by histological type was 30 months for adenocarcinoma and 71 months for squamous cell carcinoma (P=0.06). 
Conclusions: NAC was effective in downstaging 59% of patients and effectively increased the chance for an R0 resection. These patients, in turn, had improved OS compared to the median OS. Patients with squamous cell carcinoma showed a trend towards more favorable OS.},
