The role of gemcitabine in the treatment of cholangiocarcinoma and gallbladder cancer: a systematic review.

Cholangiocarcinoma and gallbladder cancer are difficult to treat curatively. The treatment of choice is surgery, dependent on detection at a resectable stage. No chemotherapy or radiotherapy options have shown substantial activity. Gemcitabine has demonstrated response in similar cancers. Considering the lack of treatment options for cholangiocarcinoma and gallbladder cancer, a systematic review of the evidence on gemcitabine use for these indications was performed.
