Analysis and prediction of the efficacy and influencing factors of camrelizumab combined with TACE and sorafenib in the treatment of advanced hepatocellular carcinoma

Abstract

Background: TACE combined with targeted therapy is a method for the treatment of hepatocellular carcinoma. After adding camrelizumab, some patients had gained benefits, but some patients have produced serious adverse reactions. Therefore, more studies are needed to prove the efficacy and adverse reactions, and prediction models are needed to help with decision-making.

Methods: With ethics committee approval, a bi-center retrospective study was finished. A total of 235 patients were enrolled and divided into the treatment group of camrelizumab combined with TACE and sorafenib and the treatment group of TACE and sorafenib. The survival rate, short-term efficacy and adverse reactions were compared, and the efficacy prediction model was established.

Results: The 2-year survival time and objective response rate of the treatment group of camrelizumab combined with TACE plus sorafenib were higher than those of TACE plus sorafenib. Camrelizumab increased the proportion of reactive capillary proliferation, but had no effect on other adverse reactions. The established nomogram can accurately predict the response to the treatment.

Conclusions: Camrelizumab combined with TACE and sorafenib can improve the survival rate of patients with hepatocellular carcinoma, and it is an effective treatment. The nomogram model can predict the efficacy, which is beneficial for patients.
