TLDR
Aggressive multimodality therapy, including neoadjuvant therapy, is essential to improve the long-term survival of patients at substantial risk of distant LN metastasis, via a complex pathway and developed into systemic disease.
Abstract
Objectives:We aimed to clarify the detailed pattern of lymph node (LN) metastasis spread in patients with pancreatic cancer.Methods:This retrospective study enrolled 429 patients who underwent pancreatectomy with extended lymphadenectomy for pancreatic cancer. The prognostic implications of LN metas

Radical surgery of oligometastatic pancreatic cancer.

TL;DR: The present collective is the largest series of resected metastatic PDAC and shows that resection of liver or ILN metastases can be done safely and should be considered as it may be superior to palliative treatment, and it is associated with long-term survival of 10% in selected patients.

M2-polarized tumor-associated macrophage infiltration of regional lymph nodes is associated with nodal lymphangiogenesis and occult nodal involvement in pN0 pancreatic cancer.

TL;DR: In this article, the authors investigated the relationship of M2-polarized TAM infiltration of the RLNs, nodal lymphangiogenesis, and occult nodal involvement in pN0 pancreatic cancer.

Cancer statistics, 2007.

TL;DR: While the absolute number of cancer deaths decreased for the second consecutive year in the United States, much progress has been made in reducing mortality rates and improving survival, cancer still accounts for more deaths than heart disease in persons under age 85 years.

Adjuvant chemotherapy with gemcitabine vs observation in patients undergoing curative-intent resection of pancreatic cancer: a randomized controlled trial.

TL;DR: The results support the use of gemcitabine as adjuvant chemotherapy in resectable carcinoma of the pancreas by significantly delayed the development of recurrent disease after complete resection of pancreatic cancer compared with observation alone.

Standard versus extended lymphadenectomy associated with pancreatoduodenectomy in the surgical treatment of adenocarcinoma of the head of the pancreas: a multicenter, prospective, randomized study. Lymphadenectomy Study Group.

TL;DR: The addition of an extended lymphadenectomy and retroperitoneal soft-tissue clearance to a pancreatoduodenal resection does not significantly increase morbidity and mortality rates, and overall survival does not differ between the two groups.

Prognostic Factors Following Curative Resection for Pancreatic Adenocarcinoma: A Population-Based, Linked Database Analysis of 396 Patients

TL;DR: Although biologic characteristics remain important predictors of survival for patients with resected pancreatic cancer, the most powerful determinant is postoperative adjuvant chemoradiation therapy.

A prospective randomized trial comparing standard pancreatoduodenectomy with pancreatoduodenectomy with extended lymphadenectomy in resectable pancreatic head adenocarcinoma.

TL;DR: Both the decrement in quality of life and similar studies showing no survival difference make PD/ELND unattractive for further prospective investigation.
