Cholangiocarcinoma
Marco Castillo
Definition. Uncommon cancer.
Anywhere along the biliary system.◦ 40 – 60% in the hilum (Klatskin tumors).◦ 20 – 30% in the distal biliary lower tract.◦ 10% Intrahepatic.◦ 10% Multifocal.
Bad prognosis.
Bismuth-Corlette classification of hilar cholangiocarcinoma.
Type I Type II
Type IIIa Type IIIb
Type IV
Epidemiology 1 – 2 of 100.000 in the US.
More common in:◦ Native American. Japanese.
> 65 years. Men > Women.
Risk factors:◦ Primary Sclerosing Cholangitis.◦ Choledochal cyst.◦ Prior transduodenal sphincteroplasty.◦ Biliary parasitic infection.
◦ Clornochis sinensis. ◦ Opisthorchis viverrini
◦ Teratogens: Asbestos, Nitrosamines, Thorotrast, Dioxin.
Pathology.
Poorly differentiated Adenocarcinoma.Desmoplastic reaction.Longitudinal growth.
Classification:◦ Mass forming.◦ Periductal-infiltrating,◦ Intraductal-papillary.
Pathology.
Pathology.CLINICAL PRESENTATION.
Painless Jaundice.
Direct hyperbilirubinemia.
Pain.
Dark urine.
Acholia.
Cholangitis.
Steatorrhea.
Anorexia.
Weight loss.
DIAGNOSIS.
Contrast CT or MRI.Shows arterial and Venous enhancement.
Cholangiography. MRCP. ERCP.

Treatment: UNRESSECTABILITY CRITERIA:
Medical contraindication to surgical intervention
Advanced cirrhosis/portal hypertension.
Bilateral second-order biliary involvement.
Main portal vein involvement.
Lobar atrophy with contralateral second-order biliary radicle involvement.
Lobar atrophy with contralateral portal vein involvement.
N2 nodal involvement.
Distant metastases.
Treatment:SURGICAL TREATMENT:
Intrahepatic cholangiocarcinoma Hepatic segmentectomy o lobectomy.
Distal extrahepatic Pancreatoduedenectomy.
Hiliar Biliar duct resection +/- Hepatic lobectomy.
PSC Neoadjuvant + Radiation + Liver transplantation.
Goal is to decrease pain and jaundice symptoms.
ERCP o Percutaneous stent.
PALLIATION:
Clinical pearls: Cholangiocarcinoma is a disease with different clinical presentation.
CT with contrast and MRI are the best diagnostic tools for Cholangiocarcinoma, followed by Cholangiography.
Classification and localization of the Cholangiocarcinoma determines treatment and prognosis.
Surgical resection, is the best treatment available.
Patients without resectability criteria should be evaluated for Neoadjuvant therapy and Palliation.
