Sorafenib improves the survival of patients with advanced hepatocellular carcinoma: a meta-analysis of randomized trials

There is no effective systemic therapy for patients with advanced hepatocellular carcinoma (HCC) except liver transplantation. Sorafenib, a multikinase inhibitor, has been shown to significantly increase overall survival (OS) in a randomized, placebo-controlled, phase III trial of patients with HCC (SHARP). The aim of this study was to evaluate the effectiveness of sorafenib for advanced HCC by carrying out a meta-analysis of randomized controlled trials that compared sorafenib-based therapy with other agent-based therapy. Randomized controlled trials comparing sorafenib or combined chemotherapy with placebo or combined chemotherapy in advanced HCC between 2000 and 2008 were identified and the data were extracted from reports. Outcomes analyzed were objective response rate, time to progression (TTP), OS, and toxicity. The summary hazard ratios (HRs), odds ratios, and their 95% confidence intervals (CIs) for mortality, objective response rate, and toxicity were estimated. All statistical tests were two-sided. Three trials including 924 patients were identified. Sorafenib-based chemotherapy was also associated with a 79% prolongation of TPP (HR = 0.58, 95% CI = 0.49-0.69, P<0.001), and a 37.3% increase in OS (HR = 0.66, 95% CI = 0.55-0.78, P<0.001). Despite significant increases in the frequencies of hand-foot syndrome and diarrhea in patients receiving sorafenib-containing chemotherapy, no significant difference in other toxic events was observed. This meta-analysis suggests that sorafenib-based chemotherapy is superior to placebo-based chemotherapy in terms of TPP and OS without increase in severe toxic effects.

Treatment of advanced hepatocellular carcinoma with long-acting octreotide: a phase III multicentre, randomised, double blind placebo-controlled study

BACKGROUND

A previous study reported a significant survival benefit for octreotide compared with no treatment in patients with advanced hepatocellular carcinoma (HCC). This was investigated further in this multicentre study.

PATIENTS AND METHODS

Two hundred and seventy two patients with HCC who were ineligible for curative treatments or had relapsed following potentially curative therapies were randomised to receive long-acting octreotide, 30 mg as an intramuscular injection once every 4 weeks for up to 2 years, or placebo.

RESULTS

At the time of the final analysis, median overall survival (OS) was 6.53 months (95% confidence interval [CI], 4.8-8.3) for octreotide versus 7.03 months (95% CI, 5.43-8.53) for placebo (p=0.34). Progression-free survival (p=0.26) also did not differ significantly between the two treatment groups. No objective responses were achieved in the octreotide group but 33% of patients achieved disease stabilisation for a mean time of 5.5 months (95% CI, 1.1-9.9). The median time until definitive global health score deterioration (according to QLQ-C30) was 2.3 months (95% CI, 1.4-3.7) in the octreotide and 4 months (95% CI, 2.2-5.7) in the placebo group (p=0.09). There were four objective responses in the placebo group. Octreotide was well tolerated; seven patients reported severe adverse events possibly related to octreotide and there were no cases of haematoma or cholecystitis.

CONCLUSIONS

In patients with advanced HCC, octreotide has a favourable safety profile but does not improve OS and could have a negative impact on quality of life.
