Molecular Targeted Therapy for Advanced Hepatocellular Carcinoma

Systemic chemotherapy has had a disappointing
track record in the management of advanced hepatocellular carcinoma
(HCC). Single-agent doxorubicin produces a response rate of 10-15%,
but without any survival benefit, and combination chemotherapy has
also yielded unimpressive results. With recent advances in the knowledge
of hepato-carcinogenesis, there has been encouraging development in
the systemic therapy of advanced HCC patients, and particularly in
the targeted therapy of advanced HCC. Among the newly identified targets,
exciting results have been shown in targeting the anti-angiogenic
pathway and the Raf/mitogen-activated protein kinase (MAPK) pathways.
Bevacizumab both as a single agent and in combination with other agents
has shown initial encouraging activity in treating advanced HCC. More
recently, single agent sorafenib, a putative multi-targeted kinase
inhibitor, has shown to prolong the overall survival of patients with
advanced HCC in the pivotal phase III SHARP and Oriental study. Currently,
sorafenib is the only approved targeted therapy for patients with
advanced HCC. In addition, however, promising early results have been
reported for other molecularly-targeted drugs including erlotinib
and sunitinib. Future progress seems likely to depend upon using controlled
clinical trials to optimize synergistic combination treatments.
