Background: Gastric cancer is a major cause of death and a substantial socioeconomic burden in Korea. The National Cancer Screening Program for Medicaid recipients was initiated in 1999 and has contributed to reduction of cancer-related mortality in Korea. Endoscopy may be cost-effective screening tool in Korea, where the cost of endoscopy and UGIS are similar and the incidence of gastric cancer is high. Most of Japanese studies on the efficiency of mass screening for gastric cancer have dealt with photoflurography as a screening tool. Although biennial gastric cancer screening by endoscopy has been increasing in Korea as part of the National Cancer Screening Program, few studies have evaluated its efficiency. Therefore, we analyzed the outcomes and efficiency of the National Gastric Cancer Screening Program using endoscopy in Korea. Methods: We reviewed medical records from the National Gastric Cancer Screening Program at Chung-Ang University hospital in Korea from January 2007 to December 2010. The study population was comprised of Medicaid recipients ≥ 40 years of age who were taken from the National Health Insurance Corporation. Results: A total of 41,150 asymptomatic subjects underwent endoscopy for gastric cancer screening. The mean age of the screened subjects was 56.3 years for men and 48.9 years for women. The male to female ratio of the screened subjects was 1.57:1. Gastric cancer was diagnosed in 102 (0.24%) of 41,150 subjects (60 men and 42 women). Their mean age was 54.4 years. Of these, 76 subjects (0.18%) were diagnosed as early gastric cancer and 26 subjects (0.06%) as advanced gastric cancer. The proportion of early gastric cancer among total gastric cancers was 74.5%. During the period, only 6,586 (16.0%) subjects participated in the biennial gastric cancer screening (59% for men and 49% for women). Conclusions: Despite accomplishments of the National Gastric Cancer Screening Program in Korea, low compliance to the screening program remains an issue. Furthermore, its cost-effectiveness analysis will be needed for successful progression.
