To enhance the efficacy of abdominal echography, 3,970 people at high risk have been chosen from a mass screening of the stomach since may 1980. 942 individuals with 1,057 lesions including 22 primary malignancies of the liver, gallbladder, pancreas, and ren were found. Of the four were detected in the operable stages. To detected malignancies in their early (curable) stages, those examines at low risk should be more aggressively pursued, despite the tendency for the relative rate of detection to decline.
为提高腹部超声检查的效能，自1980年5月起，从大规模胃部筛查中选取了3970名高危人群。发现942人有1057处病变，其中包括22例肝脏、胆囊、胰腺和肾脏的原发性恶性肿瘤。这4例中的4例在可手术阶段被检测到。为了在早期（可治愈）阶段检测到恶性肿瘤，尽管检测相对率有下降趋势，但仍应更积极地对低风险人群进行检查。
