[A national survey of 1098 cases with extrahepatic biliary cancer].

According to the resolution of the national coordinative conference, 1098 cases with extrahepatic biliary cancer, from 1977, January to 1989, April were collected by over 40 hospitals and coordinative groups throughout the country. Of 826 cases (75.2%) were bile duct cancer while 272 cases (24.8%) were carcinoma of gallbladder. An yearly increasing tendency towards bile duct cancer was found with the resection rate of 11.1-33.3%, and the upper bile duct cancer accounts for 58.4% with the surgical resection rate of 10.4%. Most of the carcinoma of gallbladder were in the late stage, of 58.4% with the whole gallbladder involved, 18.0% with the bile duct implicated and the total resection rate was 52.2%. The clinical character of bile duct and gallbladder cancer, the relationship between cancer and cholelithiasis, lymphatic and hepatic metastasis and comparison with various way of treatment and the therapeutic results were discussed and analysed statistically.
