Prospective randomized controlled trial to compare laparoscopic distal gastrectomy (D2 lymphadenectomy plus complete mesogastrium excision, D2  + CME) with conventional D2 lymphadenectomy for locally advanced gastric adenocarcinoma: study protocol for a randomized controlled trial

DiscussionPrevious studies have demonstrated the safety and feasibility of D2  + CME for locally advanced gastric cancer; however, there is still a lack of evidence to support its therapeutic effect. Thus, we performed this randomized trial to investigate whether D2 + CME can improve oncologic outcomes of patients with locally advanced gastric cancer. The findings fro m this trial may potentially optimize the surgical procedure and may improve the prognosis of patients with locally advanced gastric cancer.Trial,NCT01978444.

AbstractA 63-year-old man had advanced poorly differentiated gastric adenocarcinoma with para-aortic lymph node metastases. No HER2 expression was observed in four endoscopic biopsies from the primary tumor. Tumors shrunk after S-1 with cisplatin treatment, and he underwent simple gastrectomy due to stenosis. Interestingly, HER2 diffusely overexpressed in the resected surgical specimen. His disease was stable with trastuzumab-containing therapy for 6.4  months. This case may suggest a selection of HER2-positive cells that were insensitive to the chemotherapy, and further study is needed for the change of intratumoral ...

Authors: Tian X, Wang N Abstract Pancreatic ductal adenocarcinoma (PDAC) remains a major cause of cancer-associated mortality, with poor patient outcome. The present study aimed to identify key candidate genes and investigate the potential molecular mechanisms associated with the progression of PDAC. The GSE46234 dataset was downloaded from the Gene Expression Omnibus database, in order to identify the upregulated differentially expressed genes (DEGs) in PDAC. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to determine the biological functions and pathways of the upreg...

Authors: Prinz C, Weber D Abstract Dysregulation of noncoding microRNA molecules has been associated with immune cell activation in the context of Helicobacter pylori induced gastric inflammation as well as carcinogenesis, but also with downregulation of mismatch repair genes, and may interfere with immune checkpoint proteins that lead to the overexpression of antigens on gastric tumor cells. Numerous miR-molecules have been described as important tools and markers in gastric inflammation and cancer development -including miR-21, miR-143, miR-145, miR-201, and miR-335- all of which are downregulated in gastric tumo...

This study aimed to investigate the correlation between the four OMP genes (babA,oipA,sabA, andhomB) and gastroduodenal diseases. One hundred and seventy-sevenH. pylori strains were isolated from Chinese patients with different gastroduodenal diseases (49 chronic gastritis, 19 gastric ulcer, 33 gastric cancer, and 76 duodenal ulcer), 94 of which contained pathological information (41 superficial gastritis, 24 intestinal hyperplasia, and 29 gastric adenocarcinoma). The full-length amplification ofbabA,oipA,sabA,and homB genes was acquired and sequenced. Then, the genetic polymorphism was analyzed to compare with the referen...

Abstract BACKGROUND: The significance of perineural (PNI), lymphatic (LI) and venous invasion (VI) in gastric cancer patients who have received neoadjuvant chemotherapy is unclear. The aim of this study is to determine the incidence and prognostic significance of LI, VI and PNI in these patients. PATIENTS AND METHODS: Consecutive patients treated with neoadjuvant chemotherapy followed by gastrectomy with D2 lymphadenectomy were reviewed. Presence of LI, VI and PNI was recorded and correlated with clinical outcomes. RESULTS: A total of 243 patients underwent gastrectomy after neoadjuvant therapy for gastr...

This study assesses survival improvement across a decade (2004 –2013) among patients with metastatic gastrointestinal cancers in a real-world setting.MethodsSurveillance, Epidemiology and End Results (SEER) database was accessed and patients with metastatic gastrointestinal carcinomas who have received any form of systemic therapy were included. Patients were grouped into three cohorts based on the year of diagnosis (cohort-1: 2004 –2006; cohort-2: 2008–2010; cohort-3: 2012–2013). Overall survival was compared among the three cohorts for each disease site using Kaplan-Meier survival estimates.Result...
