Oncological outcomes of endoscopic vs. surgical resection for poorly differentiated early gastric cancer: a Surveillance, Epidemiology, and End Results based retrospective propensity score study

In this retrospective study on PDEGC utilizing the SEER database, our analysis suggests that endoscopic resection for PDEGC was associated with significantly worse CSS and OS compared with surgical resection. These findings reinforce the current guideline recommendations favoring surgical resection as the treatment of choice for PDEGC to achieve optimal oncological safety.
