Long-term risk of metachronous gastric neoplasms after curative endoscopic submucosal dissection for early gastric cancer.
BACKGROUND There is currently no consensus on long-term risk stratification for metachronous gastric neoplasms (MGNs) occurring beyond 5 years following endoscopic submucosal dissection (ESD).This study aimed to investigate the time-dependent changes in predictive factors for MGN after curative ESD for early gastric ca...
