Factors that affect surgery after endoscopic resection of early gastric cancer patients

Abstract

Purpose: The increase in the incidence of early gastric cancer (EGC) cases has led to an increase in endoscopic resections, thereby resulting in an increasing number of endoscopic resection failure cases. The purpose of this study was to identify indicators for endoscopic resection, such as depth of invasion and tumor differentiation. Methods: This study included 273 patients who underwent endoscopic resection for EGC at Hallym University Sacred Heart Hospital from January 2006 to May 2013. Of these resection cases, 41 were also surgical treatment cases. The endoscopic findings and lesion characteristics were analyzed, retrospectively using medical records. Results: The results suggested that when the location of tumor was in the middle third of the stomach (P=0.002), the patient was younger (P=0.057), there was a higher likelihood of surgical treatment after endoscopic resection. Conclusion: To determine the indicators for endoscopic resection, it is essential to consider tumor location as well as tumor size, tumor differentiation and depth of invasion, which are considered important factors. If the lesion was located in the upper and middle third of the stomach, sufficient explanation and consent was required.
