Multi-mode tumor treatment systemSintilimab+mFOLFOX6 or FOLFIRI+bevacizumab or cetuximab
Multi-mode tumor treatment system: All subjects are treated using the multi-mode tumor treatment system (Shanghai MAaGI Medical Technology Co., Ltd), with the treatment procedure conducted according to the temperature control mode for tumor ablation. Complete ablation of intrahepatic lesions is achieved to realize an intrahepatic no-evidence-of-disease (NED) state. For lesions that could not be ablated in a single session, two treatments are performed to achieve NED within the liver.
Sintilimab+mFOLFOX6 or FOLFIRI+bevacizumab or cetuximab: Systemic therapy including PD-1 inhibitor starts on the 7th day after ablation (sintilimab 200 mg IV D1 + mFOLFOX6 or FOLFIRI + bevacizumab or cetuximab (determined according to the subject's first-line chemotherapy regimen), Q3W, chemotherapy for 4-6 cycles. Sintilimab continues until disease progression, not exceeding a maximum of 2 years.）
Study summary
The goal of this study is to evaluate the efficacy and safety of multi-mode ablation combined with systemic therapy including PD-1(programmed death receptor 1) inhibitor for colorectal cancer liver metastasis and furthermore to clarify its application value by comparing preoperative and postoperative immune indicators.

Primary outcome measure(s)
Progression Free Survival (PFS) — max 24 months Progression free survival (PFS) is defined as the time from the start of treatment until the criteria for documented progression of disease (or until death due to any cause) are met, whichever comes first according to RECIST 1.1.
