Imaging bile duct tumors: pathologic concepts, classification, and early tumor detection.
Intraductal papillary bile duct tumors may be identified in some patients with biliary obstruction and are classified as in situ tumors (Tis).
Exelixis' development pipeline currently covers cancer and metabolism and is comprised of the following compounds: XL119 (becatecarin), for which a Phase 3 clinical trial has been initiated in patients with bile duct tumors; XL784, initially an anticancer compound, which has completed a Phase 1 clinical trial and is currently being developed as a treatment for renal disease; XL647 and XL999, which are currently in Phase 1 clinical trials; XL880, XL820, XL844 and XL184, anticancer compounds that are potential IND candidates; and multiple compounds in preclinical development for diseases including cancer, lipid disorders, hyperlipidemia and congestive heart failure.
Carcinomas arising in the middle portion of the extrahepatic bile duct are classified according to their treatment (combined hepatic and hilar resection for perihilar tumors, pancreaticoduodenectomy for distal bile duct tumors).
Data presented at the 2003 annual meeting of the American Society of Clinical Oncology (ASCO) from the Phase 2 clinical trial of XL119 showed that patients with bile duct tumors (gall bladder tumors and cholangiocarcinomas) treated with XL119 showed encouraging results relative to overall survival and progression free survival (alive without progressive disease, i.e., patients with partial response or stable disease).
