Abstract
Early gastric cancer (EGC) is defined as an adenocarcinoma confined to the mucosa or submucosa (T1a or T1b) of the stomach regardless of the nodal status (any N). EGC can be difficult to diagnose as the majority of patients are asymptomatic. The only exceptions are countries where nation-wide screening program is implemented, such as Japan and Korea, in which the diagnostic rates of EGC are reported to be more than 50%. With appropriate treatment, it is possible to achieve a 5-year survival rate up to 97–99% for intramucosal tumors and 96% for those involving submucosa [1].
