Introduction We evaluated the prognostic accuracy of LN variables (N0/N1), numbers of
positive lymph nodes (PLN), and lymph node ratio (LNR) in the context of the total number of …

Background We evaluated the prognostic significance and universal validity of the total
number of evaluated lymph nodes (ELN), number of positive lymph nodes (PLN), lymph …

Introduction The impact of the number of lymph node (LN) evaluated pathologically on
accurate staging is unknown. Our primary aim was to determine a minimum number of …

Background The objective of this study was to compare the prognostic significance of the
lymph node ratio (LNR) with the absolute number of affected lymph nodes for resected …

Objective: To determine the prognostic value of PLN and LNR based on a large series with
standardized lymphadenectomy and pathological workup. Background: Lymph node (LN) …

BACKGROUND Pancreatic ductal adenocarcinoma is the most common pancreatic cancer.
Five-year overall survival is currently 3.3–6.0%. The aim of this review was to evaluate the …

Background Lymph node ratio (LNR) may be more useful than nodal (N) status in prognostic
subclassification of adenocarcinomas after pancreatoduodenectomy. Ampullary (AC), biliary …

Background Survival after resection of pancreatic adenocarcinoma is poor. Several
prognostic factors such as the status of the resection margin, lymph node status, or tumor …

Background According to some studies, the number of lymph nodes with metastases in
relation to the total number of removed lymph nodes, the lymph node ratio (LNR), is one of …

Background: Few studies have simultaneously assessed the prognostic value of the multiple
classification systems for lymph node (LN) metastases in resected pancreatic ductal …
