Evolution and impact of lymph node dissection during pancreaticoduodenectomy for pancreatic cancer

Contemporary patients have an adequate number of nodes examined during standard pancreaticoduodenectomy. This, along with rising rates of N1 cancer detection and improved survival for both node-positive and node-negative patients, suggest more accurate classification of lymph node status. However, no increased benefit is achieved beyond 30 nodes. Overall, lymph node status remains a strong prognosticator for overall survival.
