Abstract

Background Although tumor length has received little attention for staging of esophageal cancer, it may be a valid prognostic feature for node positivity and survival. Methods Through retrospective review of a prospective institutional database, esophageal cancer patients who completed esophagectomy without neoadjuvant chemoradiation were analyzed. Pathologic tumor lengths were compared with node positivity and survival through a zero-inflated negative binomial regression model and multivariable Cox proportional hazards model, respectively. Results Between January 2000 and July 2015, 98 patients met inclusion, criteria (84% male, median age of 65, 90% adenocarcinoma). Median tumor length was 2.5 cm with each 1-cm increase in length increasing the odds of node positivity (odds ratio 3.55, 95% confidence interval 1.50 to 8.40, P =.004) and decreasing overall survival (hazards ratio 1.18, 95% confidence interval 1.06 to 1.32, P
