Mass survey for hepatic, biliary tract and pancreatic diseases by the use of ultrasonography was conducted by Cancer Detection Center of Miyagi Cancer Society. Both serum liver function tests (GOT, GPT, ALP, ZTT, HBsAg and alpha-fetoprotein) and ultrasonography were employed as the first screening procedures. Since 1981, 3304 males and 3492 females were examined. Nineteen cases of malignant neoplasms (0.280%) were detected. Fifteen cases of cancer in the liver, gallbladder and pancreas (0.221%) were included. The detection rate was similar to that of gastric cancer in the gastric mass survey in Miyagi prefecture. Seven cases of hepatocellular carcinoma (0.103%), three cases of metastatic liver tumor (0.044%) and a case of hepatic cystadenocarcinoma (0.015%) were detected. Six-months and 1-year survival rates in 19 cases were 73.3 and 68.0%, respectively. The longest survival was 58 months in a case of renal cell carcinoma. Mass survey by the use of ultrasonography is considered to be available and cost-effective method to detect malignant neoplasms of hepatic, biliary tract and pancreatic diseases.
