Clinical Study of Multimodal Ablation Remodeling Immunosensitized PD-1 in the Treatment of Pancreatic Cancer With Liver Metastasis

The tumor tissue was rapidly frozen until the ice ball exceeded 5mm of the lesion tissue, kept for 5 minutes, then thawed and warmed. Then, complete ablation was performed according to the radiofrequency temperature control mode of multimodal tumor therapy to ensure that the ablation area included a safe range of 5\~10mm around the tumor.
