Abstract

BACKGROUND/AIMS
Since population-based screening for gastric cancer in Korea was implemented, endoscopic treatment of early gastric cancer has become increasingly popular. This study investigates factors affecting endoscopic curative resection of early gastric cancer in population-based screening for gastric cancer.
METHODS
We retrospectively reviewed data of patients with newly diagnosed gastric cancer who underwent treatment at Seoul St. Mary's Hospital. All patients completed questionnaires about clinical information, including interval between surveillance tests for gastric cancer.
RESULTS
Of 469 gastric cancer patients, 147 (31.3%) had undergone curative endoscopic resection, 260 (55.4%) had undergone curative surgical resection, and 62 (13.3%) underwent non-curative resection or were in an inoperable state. Patients with curative endoscopic resection had fewer alarm symptoms/signs than other groups. In multivariate analysis, regular surveillance endoscopy was the only factor predicting curative endoscopic resection (odds ratio [OR], 6.099; 95% confidence interval [CI], 2.532-14.933). In addition, patients undergoing gastric cancer screening had a significantly higher rate of endoscopic curative resection compared with subjects who had never been screened. (1-year interval: OR, 49.969; 95% CI, 6.340-393.827, 2-year interval: OR, 15.283; 95% CI, 1.833-127.406, over 2-year interval: OR, 10.651; 95% CI, 1.248-90.871). Shorter screening test intervals were associated with higher rates of endoscopic curative resection.
CONCLUSIONS
Regular surveillance testing was the independent factor predicting curative endoscopic resection of gastric cancer.
