Impact of Tumor Response After Neoadjuvant Treatment on Overall Survival Among Patients With Pancreatic Ductal Adenocarcinoma: National Cancer Database Analysis.

Background Complete pathologic response following neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) is rare; alternative markers associated with survival are needed. The aim of this study was to evaluate the impact of tumor response to NAT on overall survival (OS) in PDAC patients who received NAT and curative-intent surgery. Methods A retrospective study utilizing the 2006-2018 National Cancer Database identified 6,960 adult patients with PDAC who received NAT.

Socioeconomic Disparities in Pancreas Cancer Resection and Survival in the Veterans Health Administration.

Background: Disparities based on socioeconomic factors such as race, ethnicity, marital status, and insurance status are associated with pancreatic cancer resection, but these disparities are usually not observed for survival after resection. It is unknown if there are disparities when patients undergo their treatment in a non-fee-for-service, equal-access healthcare system such as the Veterans Health Administration (VHA).

Methods: Patients having T1-T3 M0 pancreatic adenocarcinoma diagnosed between 2006 and 2017 were identified from the VHA Corporate Data Warehouse.

CCL20 induces colorectal cancer neoplastic epithelial cell proliferation, migration, and further CCL20 production through autocrine HGF-c-Met and MSP-MSPR signaling pathways.

CCL20-CCR6 interactions promote colorectal cancer through direct effects on neoplastic epithelial cells and through modulating the tumor microenvironment. The mechanism of these effects on neoplastic epithelial cells is poorly understood. This study demonstrates that CCL20 induces secretion of hepatocyte growth factor (HGF) and phosphorylation of HGF's cognate receptor c-Met in HT29 and HCT116 colorectal cancer cell lines both in concentration- and time-dependent manners.

Associations of gender, race, and ethnicity with disparities in short-term adverse outcomes after pancreatic resection for cancer.

Background: Several studies have identified disparities in pancreatic cancer treatment associated with gender, race, and ethnicity. There are limited data examining disparities in short-term adverse outcomes after pancreatic resection for cancer. The aim of this study is to evaluate associations of gender, race, and ethnicity with morbidity and mortality after pancreatic resection for malignancy.

Unraveling the identity of gastric cardiac cancer.

The classification of gastric cardiac carcinoma (GCC) is controversial. It is currently grouped with esophageal adenocarcinoma (EAC) as an adenocarcinoma of the gastroesophageal junction (GEJ). Recently, diagnostic criteria for adenocarcinoma in the GEJ were established and GCC was separated from EAC.

The improvement in post-operative mortality following pancreaticoduodenectomy between 2006 and 2016 is associated with an improvement in the ability to rescue patients after major morbidity, not in the rate of major morbidity.

Background: The postoperative mortality rate of pancreaticoduodenectomy is decreasing over time. It is unknown whether this is related to reduction in incidence of major morbidity or failure to rescue. We aimed to make this determination.

Discharge destination following rectal cancer resection: an analysis of preoperative and intraoperative factors.

Purpose: Rectal cancer resections can be associated with long and complicated postoperative recoveries. Many patients undergoing these operations are discharged to rehabilitation or skilled nursing facilities. The purpose of this study was to identify preoperative and intraoperative factors associated with increased risk for non-home discharge after rectal cancer resection.

Twenty-Three-Hour-Stay Colectomy Without Increased Readmissions: An Analysis of 1905 Cases from the National Surgical Quality Improvement Program.

Background: Isolated case series from highly specialized centers suggest the feasibility of a 23-h hospital stay after colectomy. We sought to determine preoperative variables associated with discharge within 23 h after colectomy to identify patients best suited for a short-stay model.

Methods: The American College of Surgeons NSQIP Colectomy-Targeted database was used to identify patients who underwent elective colectomy from 2012 to 2017.

Prediction of Discharge Destination Following Major Hepatectomy.

Background: Anatomic hepatectomies can be associated with complicated post-operative recoveries, often with discharge to post-acute care facilities. This study identifies preoperative and intraoperative factors associated with increased risk for non-home discharge destination after major hepatectomy.

Methods: Patients undergoing major hepatectomy were identified in the NSQIP Targeted Hepatectomy Dataset (2014-2016).

Fast-Track Pancreaticoduodenectomy: Factors Associated with Early Discharge.

Background: Pancreaticoduodenectomy is a complex surgery frequently associated with prolonged hospitalizations. However, there are a subset of patients discharged within 5 days from surgery; the preoperative and intraoperative characteristics of this subset are unknown.

Methods: The NSQIP Targeted Pancreatectomy Dataset was used from 2014 to 2016.

Discharge destination following pancreaticoduodenectomy: A NSQIP analysis of predictive factors and post-discharge outcomes.

Introduction: Pancreaticoduodenectomy is a complex surgical procedure. The purpose of this study was to identify factors associated non-home discharge destination and to characterize outcomes after non-home discharge.

Methods: 10,719 pancreaticoduodenectomy cases contained in the National Surgical Quality Improvement Program (NSQIP) Targeted Pancreatectomy dataset (years 2014-2016) were examined with univariate and multivariate logistic regression.

Low risk of lymph node metastasis in 495 early gastric cardiac carcinomas: a multicenter clinicopathologic study of 2101 radical gastrectomies for early gastric carcinoma.

Clinical decision-making on endoscopic vs. surgical resection of early gastric cardiac carcinoma remains challenging because of uncertainty on risk of lymph node metastasis. The aim of this multicenter study was to investigate risk factors of lymph node metastasis in early gastric cardiac carcinoma.

ATP-binding cassette member B5 (ABCB5) promotes tumor cell invasiveness in human colorectal cancer.

ABC member B5 (ABCB5) mediates multidrug resistance (MDR) in diverse malignancies and confers clinically relevant 5-fluorouracil resistance to CD133-expressing cancer stem cells in human colorectal cancer (CRC). Because of its recently identified roles in normal stem cell maintenance, we hypothesized that ABCB5 might also serve MDR-independent functions in CRC. Here, in a prospective clinical study of 142 CRC patients, we found that ABCB5 mRNA transcripts previously reported not to be significantly expressed in healthy peripheral blood mononuclear cells are significantly enriched in patient peripheral blood specimens compared with non-CRC controls and correlate with CRC disease progression.

Unplanned reoperation after hepatectomy: an analysis of risk factors and outcomes.

Background/purpose: Reoperation is being increasingly utilized as a metric for surgical care quality. The aim of this study was to identify the incidence of and risk factors for unplanned reoperation following index hepatectomy.

Methods: Pre, intra- and post-operative information of patients who underwent partial hepatectomy in 435 hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program from 2011 to 2013 were analyzed.

Risk Factors of Reoperation After Pancreatic Resection.

Background: Pancreatic resection is associated with a high incidence of postoperative complications, some of which require reoperation.

Aims: To analyze the incidence of and risk factors for reoperation following pancreatectomy.

Methods: Pre- and postoperative information and procedure characteristics of 15,549 patients having undergone pancreatectomy in 435 hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program from 2011 to 2014 were analyzed.
