The Efficacy and Safety of Ramucirumab in Heavily Pretreated Advanced Hepatocellular Carcinoma.

BACKGROUND/AIM:Ramucirumab has been approved for the management of hepatocellular carcinoma (HCC) after progression on sorafenib; however, the data on ramucirumab in heavily pretreated HCC are limited. This study aimed to investigate the real-world efficacy and safety of ramucirumab in patients with heavily pretreated advanced HCC. PATIENTS AND METHODS:Patients with advanced HCC who received intravenous ramucirumab as second-line and later therapy were retrospectively reviewed. Kaplan-Meier method was used to analyze progression-free survival (PFS) and overall survival (OS). Additionally, prognostic factors were estimated using hazard ratios with 95% confidence intervals. RESULTS:In total, 31 patients with advanced HCC who received ramucirumab were enrolled, including 11 patients with second-line treatment and 20 with third-line and later-line treatment. The objective response rate was 3.2% with a disease control rate (DCR) of 45.2%, and the DCR of ramucirumab between the second-line group and the third-line and later-line groups did not differ. The median PFS and OS were 2.1 months and 6.7 months, respectively, in the whole population. In the multivariate analyses, alpha-fetoprotein <1,000 ng/ml was an independent prognostic factor for better PFS and OS. All adverse events were classified as grade 1-2 without grade 3-4 toxicities or drug-related mortality. Additionally, 51.6% of patients received subsequent therapy after progression on ramucirumab. CONCLUSION:The results of our study show the efficacy and safety of ramucirumab in patients with heavily pretreated HCC in real-world practice.
