Novel gene mutations associated with bile duct cancer

Investigators at the Massachusetts General Hospital (MGH) Cancer Center have identified a new genetic signature associated with bile duct cancer, a usually deadly tumor for which effective treatment currently is limited. Their report, which has been published online in The Oncologist, finds that growth-enhancing mutations in two related genes may account for nearly a quarter of bile duct tumors arising within the liver, presenting the possibility that drugs targeting this mutation could represent a new strategy to control tumor growth.
