A. Pancreatic cancer background In 2012, 1,172 new pancreatic cancer patients were diagnosed in Switzerland. Only 20% of the patients with newly diagnosed pancreatic cancer are candidates for surgical resection, the only potential treatment for cure. Over 30% of the patients initially present with locally advanced disease. Patients with locally advanced disease have no evidence of metastatic spread to the liver, lung, and peritoneum but present with local involvement of vital structures that prohibits reasonable tumor resection. Currently, those patients are evaluated for palliative chemotherapy +/- radiation therapy. However, even with best conventional medical therapy, median survival of patients with locally advanced disease is mostly below 1 year. Over the last years, loco-regional therapies gained increased attention including radiofrequency-, cryo-, and microwave ablation as well as electrochemotherapy. However, all those entities are criticized by their complication rates leading to morbidity and mortality, limited area of application given the complex anatomical structures around the pancreas, and ill-defined improvements in overall survival.
