Abstract Background Patients with high body mass index are associated with a higher risk of complications after open pancreatectomy. We aimed to investigate the perioperative outcome for patients with high body mass index after robotic pancreatectomy. Methods This is a retrospective, propensity-score matched cohort analysis. From our prospectively maintained database, we identified consecutive patients with body mass index >25 who underwent robotic pancreatectomy between January 2016 and Decembe...

Objective: :The aim of this study was to investigate the key molecular alterations in small primary pancreatic neuroendocrine tumors (PanNETs) associated with the development of liver metastases.Background:Well-differentiated PanNETs with small size are typically indolent; however, a limited subset

Nodal involvement has been identified as one of the strongest prognostic factors in patients with nonfunctional pancreatic neuroendocrine tumors (NF-PanNETs). Sufficient lymphadenectomy and evaluation is vital for accurate staging. The purpose of this study was to identify the optimal number of examined lymph nodes (ELN) required for accurate staging. The SEER database was used to identify patients with resected NF-PanNETs between 2004 and 2014. The distributions of positive lymph nodes (PLN) ra...

OBJECTIVE: To evaluate the influence of consensus guidelines on the management of intraductal papillary mucinous neoplasms (IPMN) and the subsequent changes in pathologic outcomes. BACKGROUND: Over time, multiple guidelines have been developed to identify high-risk IPMN. We hypothesized that the development and implementation of guidelines should have increased the percentage of resected IPMN with high-risk disease. METHODS: Memorial Sloan-Kettering (MSK), Johns Hopkins (JH), and Massachusetts G...

BACKGROUND: The minimal required number of retrieved lymph nodes (MNRLNs) to enable accurate staging of distal bile duct (DBD) adenocarcinoma remains unclear. The three-tier 8th N staging system of the American Joint Committee on Cancer (AJCC) for DBD adenocarcinoma has been recently released. The present study is aimed at proposing the MNRLNs for accurate staging and validating the 8th N stage. METHODS: Between 1991 and 2015, patients with pathologically confirmed DBD adenocarcinoma who underwe...

Abstract Introduction The incidence, timing, and implications of recurrence in patients who underwent neoadjuvant treatment and surgical resection of borderline resectable (BRPC) or locally advanced (LAPC) pancreatic cancer are not well established. Materials and methods Patients with BRPC/LAPC who underwent post-neoadjuvant resection between 2007 and 2015 were included. Associations between clinicopathologic characteristics and specific recurrence locations, recurrence-free survival (RFS), and ...

Purpose: In research settings, circulating tumor DNA (ctDNA) shows promise as a tumor-specific biomarker for pancreatic ductal adenocarcinoma (PDAC). This study aims to perform analytical and clinical validation of a KRAS ctDNA assay in a Clinical Laboratory Improvement Amendments (CLIA) and College of American Pathology (CAP) certified clinical laboratory. Experimental Design: Digital-droplet PCR (ddPCR) was used to detect the major PDAC-associated somatic KRAS mutations (G12D, G12V, G12R and Q...

Abstract Background The literature suggests favorable survival for patients with isolated pulmonary recurrence after resection of pancreatic ductal adenocarcinoma (PDAC) as compared to other recurrence patterns. Within this cohort, it remains unclear what factors are associated with improved survival. Methods Patients who developed pulmonary recurrence after pancreatectomy were selected from a prospective database. Predictors for post-recurrence survival (PRS) were analyzed using a multivariable...

This study aimed to understand the biology of pancreatic ductal adenocarcinoma that arises in the remnant pancreas after surgical resection of a primary pancreatic ductal adenocarcinoma, using integrated histological and molecular analysis. Patients who underwent a completion pancreatectomy for local recurrence following resection of a primary pancreatic ductal adenocarcinoma were studied with histological analysis and next-generation sequencing of the primary and the recurrent cancer. Of six pa...
