This systematic review objectively evaluates the safety and outcomes of extended pancreaticoduodenectomy with vascular resection for pancreatic cancer involving critical adjacent vessels namely the superior mesenteric-portal veins, hepatic artery, superior mesenteric artery, and celiac axis.
Electronic searches were performed on two databases from January 1995 to August 2009. The end points were: firstly, to evaluate the safety through reporting the mortality rate and associated complications and, secondly, the outcome by reporting the survival after surgery. This was synthesized through a narrative review with full tabulation of results of all included studies.
Twenty-eight retrospective studies comprising of 1,458 patients were reviewed. Vein thrombosis and arterial involvement were reported as contraindications to surgery in 62% and 71% of studies, respectively. The median mortality rate was 4% (range, 0% to 17%). The median R0 and R1 rates were 75% (range, 14% to 100%) and 25% (range, 0% to 86%), respectively. In high volume centers, the median survival was 15 months (range, 9 to 23 months). Nine of 10 (90%) studies comparing the survival after extended pancreaticoduodenectomy with vascular resection versus standard pancreaticoduodenectomy reported statistically similar (p > 0.05) survival outcomes. Undertaking vascular resection was not associated with a poorer survival.
The morbidity, mortality, and survival outcome after undertaking extended pancreaticoduodenectomy with vascular resection for pancreatic cancer with venous involvement and/or limited arterial involvement is acceptable in the setting of an expert referral center and should not be a contraindication to a curative surgery.

[Show abstract][Hide abstract] ABSTRACT: Background
Complete macroscopic tumor resection is one of the most relevant predictors of long-term survival in pancreatic ductal adenocarcinoma. Because locally advanced pancreatic tumors can involve adjacent organs, “extended” pancreatectomy which includes the resection of additional organs may be needed to achieve this goal. Our aim was to develop a common consistent terminology to be used in centers reporting results of pancreatic resections for cancer.
An international panel of pancreatic surgeons working in well-known, high-volume centers reviewed the literature on extended pancreatectomies and worked together to establish a consensus on the definition and the role of extended pancreatectomy in pancreatic cancer.
Macroscopic (R1) and microscopic (R0) complete tumor resection can be achieved in patients with locally advanced disease by extended pancreatectomy. Operative time, blood loss, need for blood transfusions, duration of stay in the intensive care unit and hospital, morbidity, and possibly also perioperative mortality are increased with extended resections. Long-term survival is similar compared to standard resections but appears to be better compared to bypass surgery or nonsurgical palliative chemotherapy or chemoradiotherapy. It was not possible to identify any clear prognostic criteria based on the specific additional organ resected.
Despite increased perioperative morbidity, extended pancreatectomy is warranted in locally advanced disease to achieve long-term survival in pancreatic ductal adenocarcinoma if macroscopic clearance can be achieved. Definitions of extended pancreatectomies for locally advanced disease (and not distant metastatic disease) are established which are crucial for comparison of results of future trials across different practices and countries, in particular for those utilizing neoadjuvant therapy.

[Show abstract][Hide abstract] ABSTRACT: Pancreatic cancer is still associated with a poor prognosis and remains-as the fourth leading cause of cancer related mortality-a therapeutic challenge. Overall long-term survival is about 1-5%, and in only 10-20% of pancreatic cancer patients is potentially curative surgery possible, increasing five-year survival rates to approximately 20-25%. Pancreatic surgery is a technically challenging procedure and has significantly changed during the past decades with regard to technical aspects as well as perioperative care. Standardized resections can be carried out with low morbidity and mortality below 5% in high volume institutions. Furthermore, there is growing evidence that also more extended resections including multivisceral approaches, vessel reconstructions or surgery for tumor recurrence can be carried out safely with favorable outcomes. The impact of adjuvant treatment, especially chemotherapy, has increased dramatically within recent years, leading to significantly improved postoperative survival, making pancreatic cancer therapy an interdisciplinary approach to achieve best results.
