Abstract
Evaluation of: Gnerlich JL, Luka SR, Deshpande AD et al. Microscopic margins and patterns of treatment failure in resected pancreatic adenocarcinoma. Arch. Surg. 147(8), 753-760 (2012). Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with one of the worst 5-year survival rates of any malignancy. Even after potentially curative surgical resection, disease may progress rapidly. It is therefore important to identify clinicopathologic factors that influence survival and may be modified to improve outcomes. The evaluated article presents data from a retrospective review of patients who underwent surgical resection for PDAC. Local recurrence (LR), distant recurrence and survival were compared between patients with a negative resection margin (R0) and those with a positive resection margin (R1). Patients with R1 posterior margins, in particular, were more likely to have LR and worse LR-free survival. In addition, this was more pronounced if patients had lymph-node involvement. Similar results have been reported in other studies and this study illustrates that standardized pathological reporting of PDAC specimens may allow further investigation of factors affecting R1 patients.
