Clinical efficacy of gemcitabine and cisplatin-based transcatheter arterial chemoembolization combined with radiotherapy in hilar cholangiocarcinoma

Figure 1 A 65-year-old man diagnosed with hilar cholangiocarcinoma. A and B: Magnetic resonance imaging (A) and magnetic resonance cholangiopancreatography (B) showed left hepatic duct and right hepatic duct branch involvement (Bismuth-Corlette type IIIa); C: Patients underwent percutaneous double stent placement; D: During transcatheter arterial chemoembolization, the branches of the hepatic artery were responsible for the blood supply of the lesion area in the hepatic angiography (arrows); E: Intensity-modulated radiotherapy plan is shown; F: Liver cirrhosis was observed at 11 mo after receiving treatment.

Figure 2 A patient with hilar cholangiocarcinoma who underwent biliary drainage. A: Before transcatheter arterial chemoembolization combined with radiotherapy, the obstruction of the junction between the left and right hepatic ducts was shown during cholangiography; B: The obstruction was reduced and local stenosis was observed after treatment.
