This is a single center, multi-cohort, phase I basket trial to evaluate the safety and efficacy of camrelizumab in combination with bevacizumab and HAIC for metastatic liver cancer after standard treatment failure

For patients with advanced primary liver cancer, immunotherapy combined anti-angiogenic therapy has gradually become the first-line standard treatment. However, for metastatic liver cancer, especially after first-line treatment failure, the current treatment options are mostly systemic chemotherapy, and there is still a lack of effective treatment methods. Compared with systemic chemotherapy, HAIC has a higher objective response rate and survival rate, and the incidence of adverse reactions is lower. At the same time, PD-1 combined with chemotherapy has become the first-line standard treatment for many cancers; referring to the expert consensus on liver metastasis of solid tumors and ongoing clinical research, the "PD-1 + anti-angiogenesis + HAIC" regimen can be used as a new research direction for posterior treatment for metastatic liver cancer.

In view of the failure of first-line chemotherapy, how to find effective chemotherapy drugs has become a top priority. HAIC guided by genetic testing may be able to screen out effective chemotherapy drugs

This study is an open-label, single-center, multi-cohort, phase I basket trial designed to explore safety and efficacy of "camrelizumab + bevacizumab + HAIC guided by genetic testing" for metastatic liver cancer after standard treatment failure

Inclusion Criteria:
