To evaluate the efficacy and safety of camrelizumab combined with apatinib mesylate in the treatment of unresectable hepatocellular carcinoma.

Combination therapy for patients with unresectable liver cancer is the future trend, and with the development of therapeutic drugs for liver cancer, especially molecular targeted drugs and immunotherapy drugs, the effective rate of liver cancer treatment has been significantly improved, and the treatment of unresectable liver cancer has gradually changed. possible. Therefore, for patients with unresectable liver cancer, how to choose a combined treatment plan will be an important means to improve the therapeutic effect of liver cancer, and it is also a hot spot in the field of clinical research on liver cancer in recent years.

Based on the above research background, this study is now designed as a non-intervention, selecting patients with unresectable hepatocellular carcinoma as the research subjects to analyze the efficacy and safety of camrelizumab combined with apatinib mesylate. In order to bring more long-term benefits to patients with unresectable hepatocellular carcinoma.
