Primary liver cancer is one of the commonest causes of death.Hepatocellular carcinoma(HCC) accounts for 90% of primary liver cancers.For patients with unresectable or metastatic HCC,conventional chemotherapy is of limited or no benefit.Sorafenib is the only systemic treatment to demonstrate a statistically significant but modest overall survival benefit,leading to an era of targeted agents.Many clinical trials of targeted drugs have been carried out with many more in progress.Some drugs like PTK787 showed potential benefits in the treatment of HCC.Despite these promising breakthroughs,patients with HCC still have a dismal prognosis.Recently,both a phase Ⅲ trial of everolimus and a phase Ⅱ clinical trial of trebananib failed to demonstrate effective antitumor activity in advanced HCC.Sorafenib still plays a pivotal role in advanced HCC,leading to further explorations to exert its maximum efficacy.Combinations targeted with chemotherapy or transarterial chemoembolization is now being tested and might bring about advances.New targeted agents such as mammalian target of rapamycin inhibitors are under investigation,as well as further exploration of the mechanism of hepatocarcinogenesis.
