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 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 …

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

BACKGROUND: Overall five year survival following pancreaticoduodenectomy for ductal
adenocarcinoma is poor with typical reported rates in the literature of 8–27%. The aim of this …

Background Lymph node metastases are prognostically significant in pancreatic ductal
adenocarcinoma. Little is known about the significance of direct lymph node invasion. Aim …

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 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 …

BACKGROUND: The presence or absence of lymph node metastases is known to be an
important prognostic factor for patients with pancreatic cancer. Few studies have …
