Hepatocellular carcinoma(HCC) is among the most common cancer diseases worldwide.Arterial hypervascularisation is an essential step for HCC tumorigenesis and can be targeted by transarterial chemoembolization(TACE).This interventional method is the standard treatment for patients with intermediate stage HCC,but is also applied as “bridging” therapy for patients awaiting liver transplantation in many centers worldwide.Usually the devascularization effect induced by TACE is transient,consequently resulting in repeated cycles of TACE every 4-8 wk.Despite documented survival benefits,TACE can also induce the up-regulation of proangiogenic and growth factors,which might contribute to accelerated progression in patients with incomplete response.In 2007,sorafenib,a multi-tyrosine kinase and angiogenesis inhibitor,was approved as the first systemic treatment for advanced stage HCC.Other active targeted compounds,either inhibitors of angiogenesis and/or growth factors,are currently being investigated in numerous clinical trials.To overcome revascularisation or tumor progression under TACE treatment it seems therefore attractive to combine TACE with systemic targeted agents,which might theoretically block the effects of proangiogenic and growth factors.Over the last 12 mo,several retrospec-tive or prospective cohort studies combining TACE and sorafenib have been published.Nevertheless,robust results of the efficacy and tolerability of such combination strategies as proven by randomized,controlled trials are awaited in the next two years.
