Risk factors predisposing to cardia gastric adenocarcinoma: Insights and new perspectives

The etiology of adenocarcinoma of the cardia and the gastroesophageal junction (GEJ) is not known and is doubted. It is thought that cardia gastric adenocarcinoma (CGA) is distinct from adenocarcinomas located in the esophagus or distal stomach, both epidemiologically and biologically. Moreover, CGA is often identified in the advanced stage having a poor prognosis. In this paper, we would like to ascertain the possible role of GC family history, lifestyle, demographics, gastroesophageal reflux disease,Helicobacter pylori infection, and multiple genetic and epigenetic risk factors as well as several predisposing conditions in susceptibility to CGA. AbstractRecent decades have seen an alarming increase in the incidence of cardia gastric adenocarcinoma (CGA) while noncardia gastric adenocarcinoma (NCGA) has decreased. In 2012, 260  000 CGA cases (age‐standardised rate (ASR); 3.3/100 000) and 691 000 NCGA cases (ASR; 8.8/100 000) were reported worldwide. Compared with women, men had greater rates for both the subsites, especially for CGA. Recently, four molecular subtypes of GC have been proposed by the Cancer Genome Atl as (TCGA) and the Asian Cancer Research Group (ACRG); however, these classifications do not take into account predisposing germline variants and their possible interaction with somatic alterations in carcinogenesis. The etiology of adenocarcinoma of the cardia and the gastroesophageal junction (GEJ) is not known. It is thought that CGA is di...

ConclusionsThese observations suggest that SYD is effective in the enhancement of antioxidant ability via activation of Nrf2 pathway and the up-regulation of Nrf2-downstream phase II enzymes expression. The anti-inflammation and antioxidant action of SYD together contributes to the prevention and treatment of ulcerrelated colorectal cancer.Graphical abstract

In this study, a novel vitamin E succinate-based formulation of Ir (VES-Ir) combined with nanoscaled characteristics and synergistic combination was constructed through esterification. The conjugation makes amphiphilic VES-Ir prodrug self-assemble into nanoparticles with a fine diameter (VES-Ir NPs, 75.4 nm) of spherical morphology. Furthermore, VES-Ir NPs with a 1:1 drug-to-drug ratio was demonstrated to possess respectable physiological stability within 72 h test, while can react to pH/esterase-sensitive drug release in lysosomes internalized into tumor cells, potentially highlighting their alleviating side effects. Comp...

LittleAbstractThis review will cover the signalling pathways leading to the phosphorylation of the Smad linker region independent of Smad carboxy terminal phosphorylation. Characterising Smad linker region as a signalling pathway in its own right will encourage comprehensive signalling studies to provide solutions for successful discovery and exploitation of drug targets. The review describes Smad transcription factor signalling distinct from Transforming Growth Factor (TGF)-β signalling. Novel signalli...

While the primary risk factor for oesophageal adenocarcinoma (OAC) and its precursor lesion Barrett ’s oesophagus (BO) is gastro-oesophageal reflux, the infection withHelicobacter pylori (H. pylori) is the dominant risk factor for gastric cancer. Reduction of reflux by dietary measures and proton pump inhibitors has some merits in OAC prevention, and the chemopreventive effect of Aspirin and statins is being widely investigated; however, improved outcome in OAC occurs primarily as the result of secondary prevention. Early detection of neoplastic lesions in Barrett ’s metaplasia can be achieved by surveillance e...

Authors: Kim JJ Abstract The incidence of gastroesophageal junction adenocarcinoma (GEJAC) in Western countries has increased in recent decades, in addition to a rise in the incidence of esophageal adenocarcinoma (EAC). Gastroesophageal reflux disease (GERD), obesity, smoking, alcohol consumption, and low Helicobacter pylori (HP) infection rate have been nominated as risk factors for such cancers. Among these risk factors, the increased prevalence of GERD and obesity and the decreased prevalence of HP infection are of special interest owing to the currently increasing prevalence of GEJAC in Western countries. Altho...

Conclusions: Regular, moderate-to-vigorous physical activity is associated with a clinically significant reduction in the risk of gastroesophageal adenocarcinomas, but mechanisms are as yet unclear, and a causal relationship remains to be proven.

CONCLUSIONS: In the proximal stomach of BE and EAC patients, OS was elevated and antioxidative capacity was reduced. This finding suggests that the gastroesophageal reflux causing BE also induces oxidative stress in the proximal stomach and may contribute to the development of cancer in the proximal stomach and gastric cardia.

ObjectiveThe incidence of proximal gastric carcinoma (PGC) is rising worldwide for unknown reasons. Herein we compare the risk factors of early PGC with distal gastric carcinoma (DGC) in patients treated at a single tertiary hospital in China. MethodsRisk factors of 379 consecutive surgically resected early gastric carcinoma (EGC) diagnosed according to the 2010 World Health Organization criteria were studied by reviewing their medical records and esophagogastroduodenoscopy/biopsy findings and interviewing patients and family members for the patients' history of environmental toxin exposure (ETE), dietary habits, family (F...
