Abstract
Hepatoblastoma (HB) is a rare malignancy of the liver affecting mainly children between 6 months and 3 years of age. As this tumor recapitulates the phenotypic and biological features of the developing liver, many processes known to be essential in early embryonic development are implicated in the genesis of HB. This chapter describes the molecular mechanisms by which HB is thought to develop and progress, including alterations of the Wnt and hedgehog signaling pathways, the insulin-like growth factor axis, the hepatocytes growth factor/c-Met pathway, and epigenetically regulated genes. How this knowledge is currently translated into clinics is furthermore discussed, with a focus on establishing diagnostic tools, systems for predicting prognosis, response to therapy, and potential novel therapeutic strategies.
