Survival analysis based on a nationwide study of patients in Israel with gallbladder cancer revealed a relatively better survival in two subgroups: (1) patients with a localized tumor at operation and (2) patients with papillary adenocarcinoma. Further breakdown demonstrated that these two factors are interrelated, ie, patients with papillary adenocarcinoma have a relatively higher frequency of localized tumors. Consequently, the group of localized papillary adenocarcinoma of the gallbladder had a median survival extending beyond five years after diagnosis as compared with one month for the total group.
