Popis: International audience; Background: Two definitions of a positive circumferential resection margin (CRM) in esophageal cancer coexist: one by the College of American Pathologists (CAP) (CRM = 0 mm) and another by the Royal College of Pathologists (RCP) (CRM = pT3) adenocarcinoma or squamous cell carcinoma were selected from 2007 to 2016. The CRM was reassessed using an ocular micrometer. Overall survival (OS) and disease-free survival were estimated with uni- and multivariate analyses. Results The study enrolled 283 patients: 48 with a positive CRM according to the CAP definition and 171 with a positive CRM according to the RCP definition. In the multivariate analysis, a positive CRM according to both definitions was significantly associated with a poor OS (CAP: hazard ratio [HR], 2.26, p < 0.001; RCP: HR, 1.42, p = 0.035). A CRM of 0 mm was predictive of a worse OS and DFS than a CRM of 1 mm or less (p < 0.0001), whereas no significant difference was found between a CRM greater than 1 mm and a CRM of 1 mm or less, indicating that the CAP definition was more accurate for predicting prognosis and recurrence. New cutoff CRM values of 100 mu m in squamous cell carcinoma and 200 mu m in adenocarcinoma were optimal for predicting OS. Conclusion The CAP definition was more accurate for predicting prognosis and recurrence. The study identified a new cutoff value of CRM according to histologic type.
