The long-term efficacy and safety of apatinib are inferior to sorafenib in the first-line treatment of advanced hepatocellular carcinoma: A systematic review and meta-analysis

Background: Apatinib, a novel tyrosine kinase inhibitor independently developed by China, has been widely used in the treatment of advanced hepatocellular carcinoma (HCC) in recent years. For more than a decade, sorafenib has been the classic first-line treatment option for patients with advanced HCC. However, the results of clinical studies comparing the efficacy and safety of these 2 drugs are still controversial. Therefore, the aim of this meta-analysis is to evaluate the efficacy and safety of apatinib versus sorafenib as first-line treatment for advanced HCC. Methods: Up to August 14, 2023, the databases of PubMed, EMBASE, Cochrane Library, ClinicalTrials.gov, China National Knowledge Infrastructure, and Wanfang were searched, and clinical studies of experimental group (apatinib or apatinib plus transarterial chemoembolization [TACE]) versus control group (sorafenib or sorafenib plus TACE) in the first-line treatment of advanced HCC were included. Two researchers evaluated the quality of the included studies and extracted the data. Revman 5.4 software was used for meta-analysis. Results: A total of 12 studies involving 1150 patients were included. Five studies are apatinib alone versus sorafenib alone, and the other 7 studies are apatinib plus TACE versus sorafenib plus TACE. The results of the meta-analysis showed that compared with sorafenib alone, apatinib could improve (OR = 3.06, 95%CI: 1.76-5.31), had no advantage in improving DCR (OR = 1.52, 95%CI: 0.86-2.68) and prolonging PFS (HR = 1.35, 95%CI: 0.94-1.96), and was significantly worse in prolonging OS (HR = 1.43, 95%CI: 1.08-1.88). Similarly, apatinib plus TACE was inferior to sorafenib plus TACE in prolonging OS (HR = 1.15, 95%CI: 1.03-1.28), although it improved ORR (OR = 1.49, 95%CI: 1.03-2.16). In terms of adverse drug events, the overall incidence of adverse events, and the incidence of drug reduction and discontinuation in the experimental group were significantly higher than those in the control group (P < .05). The incidence of hypertension, proteinuria, and oral mucositis in the experimental group was significantly higher than that in the control group (P < .05). Conclusion: In the setting of first-line treatment of advanced HCC, apatinib has improved short-term efficacy (ORR) compared with sorafenib, but the safety and long-term efficacy of apatinib are inferior to sorafenib.
