Aim: To examine the current screening for GC and CRC within East Asia by means of a questionnaire survey. Methods: Representative members of the Committee of the International Gastrointestinal Consensus Symposium provided a questionnaire to physicians in six East Asian countries. Results: A total of 449 physicians participated in this survey. In all countries, more than 70% of physicians started GC screening between 40 and 59 years. The most popular method to screen for GC was endoscopy (92.7%), but combination methods such as Helicobacter pylori (HP) antibody, barium X-ray, and tumor marker with endoscopy differed by country. For HP-positive individuals, most physicians screened every year by endoscopy, and for individuals post-HP eradication, about half of physicians (56.3%) thought there was a need to follow-up with GC screening. Among all physicians, the most common age to start CRC screening was in the 40s (39.8%) and 50s (40.9%). Based on the American Cancer Society Recommendations, a fecal occult blood test every year was the most popular method for CRC screening overall. However, among each country, this test was most popular in only Japan (76.9%) and Indonesia. In other countries, sigmoidoscopy every 5 years and total colonoscopy every 10 years were the most popular methods. Conclusion: There are similarities and differences in the screening of GC and CRC among East Asian countries. © 2012 S. Karger AG, Basel.Mahidol UniversityMedicineReviewSCOPUS10.1159/000339342
