Popis: Pancreatic cancer is notoriously one of the most aggressive cancers and still has a poor prognosis. Surgical resection is the only chance for a curative therapy approach, with which at least a 5aEuroyear survival can be achieved for 25 % of patients. Recent advances in surgical techniques have led to a change in the criteria for resectability. This review summarizes the currently available evidence on the criteria for resectability of pancreatic cancer and discusses the treatment options. The study was based on a selective literature search and a summary of the latest data on criteria for resectability is given. Patients with pancreatic cancer must be differentiated into those with primarily resectable disease, borderline resectable disease, locally advanced (primarily unresectable) and metastatic disease. While infiltration into the major surrounding venous vessels (e.g. superior mesenteric vein, portal vein and confluence of splenic vein) used to be a criterion for unresectable disease, these tumors can nowadays be safely resected in specialized centers. Tumor infiltration into adjacent arteries (e.g. hepatic artery, superior mesenteric artery and celiac artery) remains a clinical problem and surgical resection is often technically possible but associated with an increased morbidity and mortality and therefore not generally recommended. Borderline resectable tumors represent a special group for which neoadjuvant treatment concepts are increasingly being implemented. Radiological therapy response evaluation is challenging after neoadjuvant therapy as it is not usually associated with a radiologically detectable reduction in tumor volume. Pancreatic resections can nowadays be more radically performed due to advances in surgical techniques. This has led to a change in the criteria for resectability, especially concerning venous tumor infiltration.
