Interventional Radiology Management of Pediatric Liver Tumors

Abstract

Pediatric liver tumors are not only rare, they are also different from the adult liver tumors. Hepatoblastomas and hepatocellular carcinomas (HCCs) are the most common primary malignant tumors seen in children. Fibrolamellar HCC, sarcomas, cholangiocarcinoma, germ cell tumor, and rhabdoid tumor and metastatic tumors comprise the remainder of liver malignancies. Hepatic infantile hemangiomas, mesenchymal hamartoma, regenerative nodules, adenomas, and focal nodular hyperplasia are the common benign liver tumors of childhood. The Pediatric Hepatic International Tumour Trial (PHITT) is an international trial with the goal of evaluating new and existing treatments for pediatric liver tumors. Chemotherapy, surgery, and liver transplantation are well-established in the management of pediatric liver tumors. In the background of increasing incidence of pediatric tumors, and availability of newer, less invasive modalities to treat tumors, it is vital to understand the role of interventional radiology in the management of pediatric liver tumors.
