Background: Regorafenib has been shown to improve clinical outcomes compared to placebo, becoming a standard second-line therapy for sorafenib-progressed and -tolerated hepatocellular carcinoma (HCC) patients. Objective: We performed a multicentre, retrospective study in Italy and Korea to evaluate the effectiveness of the treatment sequence sorafenib–regorafenib compared with sorafenib and physician’s choice in a real-life setting. Patients and Methods: A propensity score model was developed to control the results for baseline variable imbalances between the arm treated with sorafenib and regorafenib (S–R) and the arm treated with sorafenib and physician’s choice (S–P). Survival analysis was conducted on the matched population. Results: After the application of propensity score matching, we analysed 99 patients in the arm treated with S–R and 99 patients in the arm treated with S–P. For the S–R group, the median overall survival was 22.2 months (95% CI 17.1–27.4), compared to 17.9 months (95% CI 15.1–50.0) for the S–P group. The results of the univariate analysis showed a 31% reduction of death risk for patients treated with S–R (p = 0.0382) compared to patients treated with S–P. Interaction tests highlighted the predictive role of alpha-fetoprotein (AFP), neutrophil-to-lymphocyte ratio (NLR), and extrahepatic spread. Conclusion: This study provides additional proof of the superiority of the S–R treatment over the S–P treatment approach in advanced HCC patients from a real-life setting.

Abstract

Background: Regorafenib has been shown to improve clinical outcomes compared to placebo, becoming a standard second-line therapy for sorafenib-progressed and -tolerated hepatocellular carcinoma (HCC) patients. Objective: We performed a multicentre, retrospective study in Italy and Korea to evaluate the effectiveness of the treatment sequence sorafenib–regorafenib compared with sorafenib and physician’s choice in a real-life setting. Patients and Methods: A propensity score model was developed to control the results for baseline variable imbalances between the arm treated with sorafenib and regorafenib (S–R) and the arm treated with sorafenib and physician’s choice (S–P). Survival analysis was conducted on the matched population. Results: After the application of propensity score matching, we analysed 99 patients in the arm treated with S–R and 99 patients in the arm treated with S–P. For the S–R group, the median overall survival was 22.2 months (95% CI 17.1–27.4), compared to 17.9 months (95% CI 15.1–50.0) for the S–P group. The results of the univariate analysis showed a 31% reduction of death risk for patients treated with S–R (p = 0.0382) compared to patients treated with S–P. Interaction tests highlighted the predictive role of alpha-fetoprotein (AFP), neutrophil-to-lymphocyte ratio (NLR), and extrahepatic spread. Conclusion: This study provides additional proof of the superiority of the S–R treatment over the S–P treatment approach in advanced HCC patients from a real-life setting.
