Stomach Cancer Screening in Japan and Korea
Article information
Dear Editor,
This article [1] is very impressive and shows that Korea has an effective gastric cancer screening system. I have two questions.
First, the 5-year survival rate of gastric cancer from 1993 to 1995 was remarkably low at 43.9%. Is this low survival rate due to the cancer being diagnosed at an advanced stage? I think it is because there were many cases of advanced cancer, but this data does not tell us the stage of the cancer at the time of diagnosis.
Second, until 10 years ago, upper gastrointestinal imaging was the main method of gastric cancer preventive screening in Japan, but in Korea, endoscopy has already become mainstream. Could this difference in screening methods have led to the difference in mortality and morbidity rates between the two countries? Could you provide a comparative analysis of the data from the two countries?
