How to improve the overall survival in the patients with liver oligometastasis after pancreatic ductal adenocarcinoma (PDAC) surgery is still a huge challenge in clinic. Chemotherapy is still the first-line treatment for patients with liver oligometastasis after PDAC resection. On the basis of chemotherapy, the clinical benefits of removing hepatic oligometastasis by thermal ablation are still unclear. In this study, we will recruit patients with liver oligometastasis after PDAC surgery to explore the effect of thermal ablation combined with chemotherapy on the overall survival of patients.
