Our group is evaluating the role of minimally invasive surgery for pancreatic cancer in a prospective study of comparative effectiveness to traditional open surgery. Our objective reflects a multicenter, collaborative effort including the University of Pittsburgh Medical Center, the University of Pisa (Italy), and Maastricht University (Netherlands).

Currently, more than 70% of patients with potentially resectable pancreatic cancer do not undergo potentially curative surgery. Although possible causes for this phenomenon are numerous, fear of traditional open surgery, perceived prolonged impairment of quality of life and nutrition afterward, as well as minimal proven survival benefits are all factors that can be studied in properly designed clinical trials.

Our published data to date demonstrates no apparent inferiority of cancer outcomes after minimally invasive resection, and mounting evidence suggests improved short-term postoperative outcomes and possibly better completion rates of adjuvant chemotherapy after minimal access surgery. Whether short-term benefits will translate into improved long-term outcomes and better nutrition are the subject of maturing multicenter studies. Methods to accelerate the training and adoption of new technologies are underway through evaluation of the learning curve for advanced minimally invasive surgery.
