Survival and tumor location. Survival was related to tumor location. Gallbladder carcinoma had significantly worse prognosis than cholangiocarcinoma (p = 0.001). There was no significant difference between intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC) while both had significantly better survival than gallbladder carcinoma. Median survival of gallbladder cancer was about 8 months, for ICC 20 months, for ECC 22 months.
