Cholangiocarcinoma Flashcards
general prognosis
highly lethal (most are advanced at presentation)
Symptomatology and physiology of extrahepatic cholangiocarcinomas
- become symptomatic when tumor obstructs biliary drainage system
- jaundice, pruritus, clay-colored stools, dark urine, abdominal pain, weight loss
Difference in lab presentation between extrahepatic and intrahepatic cholangiocarcinoma
Extrahepatic = biliary obstruction patten (high t bili, direct bili, and alk phos), normal transaminases initially and then can be elevated due to chronic obstruction
Intrahepatic = high ALP, serum bili normal or slightly elevated
Imaging of extrahepatic biliary cancer + imaging feature suggesting cholangio
Often small and can be missed, but ductal dilatation in absence of stone is suggestive
Clinical features of cholangiocarcinoma
Jaundice and signs of biliary obstruction without alternative explanation
Tumor markers for cholangio
CEA
CA 19-9
Staging
- MDCT abdomen/pelvis
+/- MRCP - CT chest w/ contrast
- PET if no evidence of distant mets
Early stage cholangio mgmt
- Surgery is curative but few patients present early for surgery to be an option
management of obstructive jaundice
biliary decompression
Surgical management of locoregional distal cholangiocarcinoma
pancreaticoduodenectomy (Whipple procedure)
Sugical management of intrahepatic cholangiocarcinmoa
Hepatic resection
Management of node positive loco-regional disease
Chemoradiotherapy
mets beyond what region contraindicate surgical resection
Beyond the porta hepatis (
Most common actionable mutations in cholangio
- IDH1 - R132C
- FGFR2 translocations
