[Chemotherapy in gallbladder carcinoma]

Abstract

Gallbladder cancer is an aggressive tumor. Its incidence varies according to geography. Surgery is the standard treatment for localized stage but there is no standard treatment in metastatic or locally advanced disease. Because of the rarity of bile tract cancer (BTC) and gallblader carcinoma (GBC), most studies have grouped all BTC and GBC together, and there are very few GBC-specific studies. In addition, there is a paucity of randomized controlled studies in this disease with small numbers of patients and inclusion bias. One randomized trial ABC-02 was well conducted and showed a survival benefit in favor of gemcitabine (GEM)+cisplatin (CDDP), which can be regarded as the standard in locally advanced BTC. Adjuvant therapy after surgical resection is not validated. Understanding the molecular mechanisms of carcinogenesis of GBC has opened the way for the use of targeted therapies. This new treatment would improve survival and quality of life of our patients.
