Gallbladder cancers: associated conditions, histological types, prognosis, and prevention.

Introduction: Gallbladder cancer has a poor prognosis, with a reported 5-year survival of 5%. The prognosis improves when an R0 resection is feasible, but an early diagnosis is rare. The aim of the present study is to analyze the different conditions associated with gallbladder carcinomas and to report the main prognostic factors for these tumors to enable prevention.
