Expert opinion on investigational drugs

Hepatocellular cancer (HCC) is the fifth most common malignancy worldwide and third leading cause of cancer death. HCC is highly resistant to conventional systemic therapies, and prognosis for advanced HCC patients remains poor. However, identification of signaling pathways responsible for HCC growth and progression such as RAS/RAF/MEK/ERK or PI3K/AKT/mTOR has determined crucial molecular targets and led to development of novel promising targeted therapies. ⋯ Despite significant progress, advanced HCC remains an incurable disease, and the overall efficacy of recently approved targeted therapy (sorafenib) remains moderate. It is to be hoped that several ongoing clinical trials evaluating novel targeted approaches for treatment of HCC will lead to further improvement in the management of advanced disease.
