Short- and long-term results in operable pancreatic ductal adenocarcinomas from a cooperation between two departments gastroenterology-visceral surgery at non-university hospitals benchmarked to results of expert-centers

The only curative approach in pancreatic ductal adenocarcinoma (PDAC) is resection, which is possible only in 15 - 30 % of patients. Local tumor spread or distant metastases are contraindications for resection in the majority of patients. Surgical-oncological quality with short-and long-term results are varying tremendously, so that "expertise/quality" are associated to hospital-or surgeon's volume and/or center formation. The treatment results also depend, to a great extent, on the medical diagnostic quality. With our retrospective study, we aim to compare the results-quality of cooperative pancreatic cancer treatment based on an extensive preoperative diagnostic procedure for staging and risk estimation in a specialized GI-medical department and visceral surgical-oncological expertise in pancreatic cancer surgery at a general hospital with the results-quality of expert centers. Fifty-three patients with PDAC had diagnosis and resection of their cancer between 1/2002 and 12/2009. The 30 day hospital-mortality was 3.8 % and the median survival time after demission from the hospital was 23.1 months. The 5-year-survival rate of R0-resected patients, all of whom had received adjuvant chemotherapy, was high with 31 %. The survival data and the extraordinarily high resection rate of 98.1 % in the patient group, whose primary tumor stage was pT3 in 81 %, reflects the excellent cooperation of high standards in medical diagnostic processes, visceral pancreatic surgery, and adjuvant medical chemotherapy. The results are well comparable to those of "high volume centers". The responsible heads of the two departments have been trained at university expert centers. Expertise in the treatment of pancreatic cancer patients may be successfully transferred from an expert center to a general hospital, if the team has high expertise.
