Condition esophageal cancer
Sponsor University Hospital, Gasthuisberg
Start date July 2013
End date December 2013
Trial size 923 participants
Trial identifier NCT01959906, CRM<1mm


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.

Time perspective retrospective
Complete resection
Incomplete resection, microscopical tumor residu left behind
complete resection (R0), however tumor spreads till less than 1 mm from the section pane.

Description From our prospectively build database 923 consecutive pT3 patients operated between january 1990 and june 2013 were selected. CRM status in patients treated by surgery only (n = 747) or after neoadjuvant therapy (n = 176) was recorded prospectively after surgery. Kaplan-Meier survival curves were generated, and factors affecting survival were assessed by Cox regression multivariate analysis.
