Circumferential Section Pane Less Than 1 mm in Esophagectomy for Esophageal Cancer.

A suspicious circumferential resection margin (CRM), defined as tumor cells within 1 mm of the CRM, is still controversial. The aim of this study was to compare the clinical significance of a suspicious CRM to histologically positive (R1) and negative margin (R0) resections in patients with pT3 esophageal and GE-Junction tumors.
