Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Camrelizumab combined with ablation and chemotherapy<br>First, patients with liver metastases from pancreatic cancer are given ablation of liver metastases, and conventional chemotherapy plus camrelizumab is performed 1 week after surgery. If patients have multiple metastases, ablation treatment needs to be performed in stages, each ablation After 1 week of treatment, sequential chemotherapy + camrelizumab were reinfused, and the efficacy was evaluated every 2 cycles until the disease progressed or the patient could not tolerate it. | Drug: Camrelizumab<br>* Camrelizumab was administered 200mg iv every 3 weeks<br>Drug: Chemotherapy<br>* The chemotherapy regimen may be a standard regimen for routine treatment of advanced pancreatic cancer.<br>Procedure: Ablation<br>* First give pancreatic cancer patients with liver metastases to ablation of liver metastases<br>|
