Abstract
Gallbladder cancer (GBC), although considered as a relatively rare malignancy, is the most common neoplasm of the biliary tract system. The late diagnosis and abysmal prognosis present challenges to treatment. The overall 5-year survival rate for metastatic GBC patients is extremely low. BRCA1 and BRCA2 are the breast cancer susceptibility genes and their mutation carriers are at a high risk for cancer development, both in men and women. Olaparib, an oral poly ADP-ribose polymerase inhibitor, has been approved by the Food and Drug Administration and the European Commission for the treatment of ovarian cancer with any BRCA1/2 mutations. The first case of a BRCA1-mutated GBC patient who responded to olaparib treatment is reported here.
Core tip: Gallbladder cancer (GBC) is the most common neoplasm of the biliary tract system. BRCA1, the first major breast cancer susceptibility gene, has been widely studied in breast and ovarian cancers. Olaparib, an oral poly ADP-ribose polymerase (PARP) inhibitor, has been approved by the Food and Drug Administration and the European Commission for the treatment of ovarian cancer with any BRCA1/2 mutations. However, there is no report of a germline BRCA1 functional mutation in GBC prior to this case. Even further, the GBC with a BRCA1 mutation responded to the PARP inhibitor olaparib.
