A Trial of Camrelizumab Combined With Microwave Ablation and Chemotherapy in the Treatment of Colorectal Cancer Liver Metastasis/Pulmonary Metastasis

Currently, comprehensive treatments for liver metastasis/pulmonary metastasis that cannot reach NED include systemic chemotherapy, interventional chemotherapy, molecular targeted therapy, immunotherapy, and local treatments (ablation therapy, radiation therapy, etc.) for liver metastases. Combination therapy model of local ablation, systemic chemotherapy, and anti-PD -1 monoclonal antibody hopefully can prolong patient survival. This trial will evaluate the effectiveness and safety of carrelizumab combined with microwave ablation and chemotherapy in the treatment of colorectal cancer liver metastasis/pulmonary metastasis
