title: Gallbladder cancer: past, present and an uncertain future.
abstract: Although gallbladder cancer (GBC) is the most common malignancy of the biliary tract, its relatively low incidence and confounding symptomatology result in advanced disease at the time presentation, contributing to the poor prognosis and decreased survival associated with this disease. It is therefore increasingly important to understand its pathogenesis and risk factors to allow for the earliest possible diagnosis. To date, gallbladder cancer is poorly understood compared to other malignancies, and is still most commonly discovered incidentally after cholecystectomy. Moreover, while much is known about biliary neoplasms as a whole, understanding the clinical and molecular nuances of GBC as a separate disease process will prove a cornerstone in the development of early intervention, potential screening and overall more effective treatment strategies. The present work reviews the most current understanding of the pathogenesis, diagnosis, staging and natural history of GBC, with additional focus on surgical treatment. Further, review of current adjuvant therapies for unresectable and advanced disease as well as prognostic factors provide fertile ground for the development of future studies which will hopefully improve treatment outcomes and affect overall survival for this highly morbid, poorly understood malignancy.
