早期胃癌(EGC)一词初见20世纪70年代。实际上所有进展期胃癌都经过了EGC这个阶段,但在此期被发现者却不多。目前,我国临床诊断的胃癌多为进展期胃癌,EGC的诊断率仅为7.5%左右,而日本报道EGC占临床诊断胃癌的50%。因此,目前提高我国胃癌治愈率的关键是早期诊断、早期治疗。通过 The term early gastric cancer (EGC) first appeared in the 1970s. In fact, all advanced gastric cancer have gone through this phase of EGC, but not many were found during this period. At present, most of the clinically diagnosed gastric cancers in our country are advanced gastric cancer. The diagnostic rate of EGC is only about 7.5%, while in Japan, EGC accounts for 50% of the clinical diagnosis of gastric cancer. Therefore, the key to improve the cure rate of gastric cancer in our country is early diagnosis and early treatment. by
