a neoadjuvant hepatocellular carcinoma study of camrelizumab in combination with apatinib and oxaliplatin

Conditions: Hepatocellular Carcinoma Resectable

Summary: this is a prospective, single-arm, single-center, clinical research.this trial will explore the efficacy and safety of camrelizumab in combination with apatinib mesylate and oxaliplatin for neoadjuvant therapy in patients with potentially resectable hepatocellular carcinoma.

there is no high-level evidence on the efficacy of systemic therapy in neoadjuvant studies for hepatocellular carcinoma, and guidelines recommend tace as the treatment of choice. given that combination therapies such as immunotherapy in combination with targeted therapy and immunotherapy in combination with chemotherapy have achieved good efficacy in systemic therapy for liver cancer, this study is intended to explore the efficacy of tace. in this study, we propose to explore the use of kareliozumab in combination with apatinib and oxaliplatin for the treatment of hepatocellular carcinoma. in this study, we propose to investigate the efficacy and safety of neoadjuvant therapy with kalilizumab in combination with apatinib and oxaliplatin in patients with potentially resectable hepatocellular liver cancer.
