简介:AbstractPancreatic ductal adenocarcinoma (PDAC) represents one of the most aggressive malignancies, and the majority of patients with PDAC present with metastatic disease, mainly in the liver, at the time of diagnosis. Surgical resection is the only treatment that can offer prolonged survival and possible cure. However, the indications for surgery for patients with PDAC metastases remain extremely limited to highly selected patients with localized disease, and metastatic disease is generally regarded as a contraindication to surgery. Recently, however, the advent of more effective chemotherapy has changed the treatment strategy for metastatic PDAC. In fact, cases in which resection of synchronous or metachronous PDAC liver metastases lead to prolonged survival in highly selected patients have been reported. In this review, we provide current data regarding survival outcomes after surgery, and discuss the role of surgical resection and selection criteria for patients with PDAC liver metastases in the modern era.
