Two Cases of Unresectable Cholangiocarcinoma Treated by Yttrium-90 Microspheres

Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy and many cases of ICCs are diagnosed in an unresectable state. Until now there has been no effective palliative treatment for these cases. Recently yttrium-90 (90Y) radioembolization has been highlighted as a new palliative treatment for these cases. In Korea, there has been no reported case of unresectable ICC which was treated by 90Y radioembolization up until now. We treated two cases of unresectable ICCs with 90Y radioembolization and the ICCs were necrotized effectively without significant toxicity. KCI Citation Count: 0
