Background The lymph node (Ln) status of patients with resectable pancreatic ductal
adenocarcinoma is an important predictor of survival. The survival benefit of extended …

Background The prognostic role of lymph node (LN) dissection in pancreatic head ductal
adenocarcinoma is still unclear. This study reappraised the value of the number of positive …

Hypothesis The required sample size of a prospective randomized trial comparing standard
pancreaticoduodenectomy with pancreaticoduodenectomy plus extended …

Background The value of pancreatoduodenectomy (PD) with extended lymphadenectomy
for pancreatic cancer has been evaluated by many retrospective studies and 3 randomized …

The purpose of this study was to evaluate the influence of regional versus extended
lymphadenectomy on survival after partial pancreaticoduodenectomy for pancreatic cancer …

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 …

Background The current tumor-node-metastasis staging system for the pancreas does not
incorporate the number of lymph nodes (LNs) with metastasis. Methods Among 1649 …

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

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

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) …
