New molecular therapies in patients with advanced Hepatocellular Cancer in second line of treatment: Is a real defeat?: Results from a literature based meta-analysis of randomized trials.

Several new biological agents have been investigated as second line of treatment in advanced Hepatocellular Cancer (HCC). We performed a meta-analysis to assess the effect of targeted therapies in advanced HCC patients beyond the first line of treatment. A literature-based metaanalysis of randomized controlled trials was undertaken. The primary outcome was the overall survival. The secondary endpoints were the progression-free survival (PFS), the response rate (RR) and disease control rate (DCR) and the safety. Pooled analysis of targeted agents revealed a modest increase in overall survival compared with control arm (Hazard Ratio (HR)=0.93, 95%CI: 0.83-1.04; P=0.21). On the counterpart, all the secondary endpoints were in favoured to the targeted agents-based treatment (PFS: HR=0.68, 95% CI:0.56-0.83; P=0.0002; RR: 3.50,95% CI 1.81-6.76; P=0.0002, DCR: RR:1.19, 95% CI 1.06-1.32; P=0.002). To date, there is a clinical need of a more efficacious second line of therapy in treatment of the advanced HCC. This study showed some activity of the new targeted therapies in second line of treatment in advanced HCC.
