Impact of Total Lymph Node Count and Lymph Node Ratio on Staging and Survival after Pancreatectomy for Pancreatic Adenocarcinoma: A Large, Population-Based Analysis

Abstract
Based on data from other malignancies, the number of lymph nodes evaluated and the ratio of metastatic to examined lymph nodes (LNR) may be important predictors of survival. LNR has never been investigated in a large population-based study of patients with pancreatic adenocarcinoma.
