Abstract
BackgroundSelective internal radiation therapy (SIRT) with Ytrrium-90 (Y-90) has been used to treat hepatic malignancies with success. This study focuses on the efficacy and safety of Y-90 in the treatment of unresectable and metastatic intrahepatic cholangiocarcinoma (ICC). MethodsA single-institution retrospective case review was performed for patients with unresectable and metastatic ICC treated with Y-90 between 2006 and 2016. ResultsSeventeen patients with ICC underwent 21 Y-90 treatments. Four patients had undergone prior liver resection, and six patients had extrahepatic disease at the time of treatment. Five year overall survival was 26.8%, with a median survival of 33.6 months. One patient underwent margin negative liver resection after a single treatment. Complications were appreciated in two cases. Ninety-day mortality was 0%. ConclusionTreatment of ICC using Y-90 is a safe and promising procedure. Further research is needed to clarify its role in the treatment of unresectable and metastatic ICC.
