The impact of cancer involving the peripancreatic soft tissue (PST), irrespective of margin status, following a resection of pancreatic adenocarcinoma is not known. The purpose of this study is to determine such an impact on a cohort of patients. Data from 274 patients who underwent pancreatic surgery by our team between 1998 and 2012 was reviewed. Of those 119 patients who had pancreatic resection for adenocarcinoma were retrospectively analyzed. Patients were categorized into 3 groups: Group 1 = R1 resection (N = 39), Group 2 = R0 with involved PST (N = 54), and Group 3 - R0 with uninvolved PST (N = 26). Demographics, operative data, tumor characteristics and overall survival (OS) were evaluated. Operations performed were: Whipple (N = 53), pylorus sparing Whipple (N = 41), total pancreatectomy (N = 11), and other (N = 14). Median OS for Groups 1, 2, and 3 were 8.5 months, 12 months, and 69.6 months respectively (P < 0.001). Tumor size (P = 0.016), margin status (P = 0.006), grade (P = 0.001), stage (P = 0.037), PST status (P < 0.001), complications (P = 0.046), transfusion history (P = 0.003) were all predictors of survival. Cox regression analysis demonstrated that grade (HR = 3.1), PST involvement (HR = 2.7), transfusion requirement (HR 2.6) and margin status (HR = 2.0) were the only independent predictors of mortality. PST is a novel predictor of poor outcome for patients with resected pancreatic cancer.
