The limitation of detectability and curability in terms of current techniques (screening and details) were sought in otherwise healthy examinees. Not a few cancers were present in the alimentary tract, except for the stomach, in these otherwise healthy examinees who voluntarily underwent gastric cancer mass screening. The prognosis of alimentary tract cancers deteriorates in the descending, following order: colon cancer, stomach cancer, and esophageal cancer. The survival rate of primary liver cancer, cholecyst cancer, and pancreas cancer is extremely low. Unless new techniques are developed in these diagnoses, no improvement in the survival rate can be anticipated.
在健康体检者中探寻当前技术（筛查及细节方面）在可检测性和可治愈性上的局限。在这些自愿接受胃癌大规模筛查的健康体检者中，除胃部外，消化道存在不少癌症病例。消化道癌症的预后按降序依次变差：结肠癌、胃癌和食管癌。原发性肝癌、胆囊癌和胰腺癌的生存率极低。除非在这些诊断方面开发出新的技术，否则预计生存率不会有改善。
