Scheduled endoscopic surveillance controls secondary cancer after curative endoscopic resection for early gastric cancer: a multicentre retrospective cohort study by Osaka University ESD study group

Background

After endoscopic submucosal dissection (ESD) of early gastric cancer (EGC), patients are at high risk for synchronous or metachronous multiple gastric cancers.

Objective

To elucidate the time at which multiple cancers develop and to determine whether scheduled endoscopic surveillance might control their development.

Design

A multicentre retrospective cohort study from 12 hospitals was conducted. Patients...
