Role of Node Dissection in Pancreatic Tumor Resection

Abstract

Background Pancreatic cancer is a lethal disease, and, even with modern therapies, the mortality has not decreased significantly in decades. The prognostic importance of lymph node status is well defined; however, the role of extended lymphadenectomy to improve local recurrence and overall survival remains debated. Six randomized controlled trials have evaluated the extent of lymph node dissection in pancreaticoduodenectomy for pancreatic cancer. Objective We sought to review the current literature to evaluate the role of lymphadenectomy in pancreatic cancer. The impact of each trial and its contribution to the literature is discussed. Conclusions Multiple randomized trials have failed to note an improvement in overall survival with extended lymphadenectomy for pancreatic cancer. Rather, extended lymphadenectomy was associated with increased morbidity, operating room time, and length of stay.
