The incidence of gastric cancer (GC) is high, and colorectal cancer (CRC) has significantly increased in Asian countries.
To examine the current screening for GC and CRC within East Asia by means of a questionnaire survey.
Representative members of the Committee of the International Gastrointestinal Consensus Symposium provided a questionnaire to physicians in six East Asian countries.
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.
There are similarities and differences in the screening of GC and CRC among East Asian countries.
胃癌（GC）的发病率较高，亚洲国家的结直肠癌（CRC）发病率也显著上升。
通过问卷调查的方式，考察东亚国家目前针对 GC 和 CRC 的筛查情况。
国际胃肠共识研讨会委员会的代表成员向六个东亚国家的医生发放了问卷。
共有 449 名医生参与了此次调查。在所有国家中，超过 70%的医生在 40 至 59 岁之间开始进行 GC 筛查。筛查 GC 最常用的方法是内镜（92.7%），但各国的组合方法（如幽门螺杆菌（HP）抗体、钡 X 线和肿瘤标志物联合内镜）有所不同。对于 HP 阳性者，大多数医生每年通过内镜进行筛查，对于 HP 根除后的个体，约一半的医生（56.3%）认为需要进行 GC 筛查随访。在所有医生中，开始 CRC 筛查的最常见年龄是 40 多岁（39.8%）和 50 多岁（40.9%）。基于美国癌症协会的建议，每年进行一次粪便潜血试验是 CRC 筛查的最常用方法。然而，在每个国家中，这种检测方法在日本（76.9%）和印度尼西亚最为流行。在其他国家，每 5 年进行一次乙状结肠镜检查和每 10 年进行一次全结肠镜检查更为流行。
东亚国家在 GC 和 CRC 的筛查方面存在相似之处和差异。
