Risk Of Gastric Cancer Research Articles

Gastric Cancer associated with the use of Omeprazole in Adults

Introduction: proton pump inhibitors constitute a group of drugs used to suppress stomach acid secretion and whose consumption has intensified worldwide due to their consideration as the most effective gastric protectors, omeprazole being one of the most widely used. Objectives: to analyze the existence of gastric cancer risk due to long-term use of omeprazole in adults.Methods: a search for information was carried out in PubMed and Google Scholar. Search formulas were used by combining the terms: “Omeprazole”, “Cancer Gastric”, “Omeprazole and Adverse effects”, “Omeprazole and Helicobacter Pylori”. From the total number of articles identified, after the screening process, 8 articles were chosen for the present study.Results: Prolonged treatment with omeprazole can induce histological changes in the gastric mucosa, including hyperplasia, increased gastrin-producing cells, atrophic gastritis and increased colonization of Helicobacter pylori. A rebound acid hypersecretion has been observed after discontinuation of treatment, persisting for at least two months. Endocrine hyperplasia may result from suppression of acid secretion, causing hypergastrinemia and increasing the risk of malignant lesions.Conclusions: information has been compiled on the effects of prolonged use of omeprazole and its relationship with gastric carcinoma. This use is becoming more frequent, which underlines the need to investigate its long-term effects, since it may alter gastric histoarchitecture and predispose to cancer

Incidence of Gastric Adenocarcinoma in Those With Gastric Atrophy: A Systematic Review.

Gastric atrophy (GA), or atrophic gastritis, is a pre-neoplastic lesion of gastric cancer (GC). It is part of the Correa cascade, which culminates in intestinal-type gastric adenocarcinoma. The cascade posits that intestinal-type gastric adenocarcinoma develops along a defined pathway of pre-neoplastic stages. The cascade begins with chronic gastritis, most commonly caused by Helicobacter pylori (H. pylori) infection, and proceeds through GA, gastric intestinal metaplasia (GIM), both complete and incomplete, dysplasia, both low and high-grade, and culminating in intestinal-type gastric adenocarcinoma. Attempts in Europe have been made to identify patients at risk of developing GC and target them with surveillance oesophagogastroduodenoscopy (OGD). However, there remains uncertainty about GA's risk of developing into GC. This poses issues in terms of guiding the need for and determining intervals for surveillance OGDs, which are a costly form of surveillance. As such, we attempted to gather all available studies assessing the risk of GC developing from GA, which is the first step in the Correa cascade.This study was a comprehensive systematic review of published papers, reported per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. This systematic review, which included a substantial 25,455 patients across 18 studies, found that the relative risk (RR) of GC in those with GA, using standardised incidence ratios as a measure of RR, was 15.1, with a 95% confidence interval ranging from 13.5 to 16.9. We conclude thatGA does increase the risk of developing GC, and this risk may be higher than previously appreciated. Further large-scale studies are needed in Western cohorts of patients to precisely define this risk and guide the need for surveillance programs. These future studies must be standardised to account for H. pylori status, the topographical distribution of the GA, and the methods for assessing the degree of GA.

Gastric Cancer in One-Anastomosis Mini-gastric Bypass: Case Report and Systematic Review.

In the last years, one-anastomosis gastric bypass (OAGB) has been proposed more frequently as obesity surgery technique. Several trials have demonstrated that the easier technical feasibility does not affect the long-term surgical result. However, concern about increased risk of gastric and esophageal cancers has been expressed by several bariatric surgeons. The present study reports the 2nd case of cancer of the gastrointestinal-jejunal anastomosis in a OAGB patient focusing the attention on some technical issues correlated and offering a systematic review of the literature.

Association of ANRIL Gene Polymorphisms with Gastric Cancer Risk: A Case-Control Study.

Background: Gastric cancer's (GC) cause is unknown, but its complexity indicates that, in addition to environmental factors, it may have genetic origins. Scientists are studying single-nucleotide polymorphisms (SNPs) in the antisense noncoding RNA in the INK4 locus (ANRIL) gene, which encodes a long noncoding RNA molecule. They found a link between the ANRIL gene product and some polymorphisms and GC, suggesting genetic changes may lead to precancerous conditions. Methods: In a case-control research that included 250 patients with GC and 210 controls who were age- and gender-matched, four SNPs within the ANRIL gene were genotyped. These SNPs were rs1333049, rs496892, rs2383207, and rs2151280. Tetra-primer amplification refractory mutation system-PCR was utilized to carry out the process of genotyping. Results: It was found that the chance of developing GC was connected with three SNPs rs2151280, rs1333049, and rs496892. Nevertheless, rs2383207 did not demonstrate any meaningful connection. In addition, whereas CCTC and TTCC haplotypes were shown to be less common, certain haplotypes that contained these SNPs (TTCG, TCTC, and TTTC) displayed a considerably higher prevalence in the cancer group in comparison to the control group. Conclusion: This study showed novel associations between specific ANRIL gene polymorphisms (SNPs) and the risk of GC. These findings shed light on the potential role of ANRIL SNPs in GC risk and highlight the need for additional research to clarify the underlying functional processes. Understanding these functional processes might lead to developing novel diagnostic or treatment approaches for this cancer.

Development and validation of a relatively accurate gastric cancer high-risk group screening scoring system in urban residents.

Our study aimed to develop a relatively accurate gastric cancer (GC) screening score system for urban residents and to validate the screening efficacy. The present study included a derivation cohort (n = 3406) and a validation cohort (n = 868) of urban residents. Applying the full-stack engineering intelligent system platform of Hualian Health Big Data of Shandong University, the clinical physical examination data of subjects were collected. Univariate and multivariate analyses were used to identify risk factors for GC, and subsequently, an optimal prediction rule was established to create three distinct scoring systems. In the GC-risk scoring system I, age, plateletocrit (PCT), carcinoembryonic antigen (CEA), glucose, albumin, creatinine were independent risk factors of GC, with scores ranging from 0 to 28 and optimal cut-off was 15.5. The second scoring system consisted of age, PCT, RDW-CV, CEA, glucose, albumin, and creatinine, with scores ranging from 0 to 31. The optimal cut-off point was determined to be 15.5. The scoring system III comprise of age, sex, PCT, RDW CV, CEA, glucose, with scores ranging from 0 to 21 and optimal cut-off was 10.5. All three scoring systems demonstrated excellent discrimination for GC, achieving an AUC of 0.884, 0.89, and 0.876, respectively. In external validation, the AUC values were 0.654, 0.658, and 0.714. Notably, the GC-risk scoring system III exhibited the highest screening efficiency. Urban residents benefited from the effective and verified GC-risk scoring systems, which demonstrated excellent performance in identifying individuals with an elevated risk of GC.

Public awareness of gastric cancer risk factors and screening behaviours in Shijiazhuang, China: A community-based survey.

Reducing exposure to risk factors and screening represent 2 major approaches to gastric cancer (GC) prevention, but public knowledge GC risk factors and screening behaviour remain unknown. We aimed to investigate public awareness of GC risk factors, adherence to screening, and barriers hindering screening practices in China. This community-based household survey was conducted within Shijiazhuang, China, and 1490 residents were recruited through a multistage stratified cluster random sampling approach. A self-administered questionnaire was completed which consisted of three sections: demographics, awareness of GC risk factors, and personal screening behaviours. Factors associated with knowledge of risk factors and screening behaviours were evaluated using binary logistic regression analysis. The mean risk factor awareness score of 12 (7, 15) revealed insufficient knowledge in 51.1% of participants. Dietary lifestyle factors were better understood than physical activity and weight-related factors. Marital status (OR 1.967; 95% CI 1.415 to 2.734), higher income (OR 1.197; 95% CI 1.010 to 1.418), and a history of upper gastrointestinal problems (OR 0.048; 95% CI 1.002 to 1.311) were associated with higher awareness. Merely 21.5% underwent GC screening, with higher rates linked to older age (OR 1.642; 95% CI 1.418 to 1.902), higher education (OR 1.398; 95% CI 1.176 to 1.662), a history of upper gastrointestinal problems (OR 3.842; 95% CI 2.833 to 5.209), and moderate (OR 2.077; 95% CI 1.352 to 3.191) and high (OR 2.529; 95% CI 1.311 to 4.878) perceived GC risk. Notably, participants commonly refused gastroscopy due to the absence of symptoms or signs. In Shijiazhuang, more than half of participants demonstrated inadequate knowledge of GC risk factors, and screening participation rates were remarkably low. This emphasizes the need for targeted interventions to enhance GC awareness and significantly improve screening rates.

Gastric Precancerous Lesions: From Progenitor Cell and Microsatellite Instability to Clinical Interpretation of Gastric Cancer Risk

Aim: to evaluate the possibility of the MMR-system status, microsatellite instability (MSI) usage in the differential diagnosis of gastric mucosa dysplasia, determination of the gastric adenocarcinoma development risk. Material and methods. The study included gastric mucosa specimens of 75 patients: 25 with high-grade dysplasia, 25 with low-grade dysplasia, 25 were indefinite for dysplasia. Gastrobiopsy specimens were examined histologically, immunohistochemically using mouse monoclonal antibodies (Diagnostic BioSystems, USA) to the MMR system proteins: MLH-1 (clone G168-15, dilution 1:50), MSH2 (clone DBM15.82, dilution 1:100), MSH6 (clone 44, dilution 1:50), PMS2 (clone A16-4, ready to use). MSI was studied with multiplex PCR evaluation of DNA microsatellites (NR-21, NR-24, NR-27, BAT-25, BAT-26) from paraffin sections, their analysis with capillary electrophoresis. The obtained data were processed with the Statistica 10.0 (StatSoft, USA), presented using descriptive, analytical statistics. VOSviewer (1.6.20) was used to visualize the bibliometric analysis. Results. MMR-deficient cases were found in low (2.8 %) and high-grade (2.8 %) dysplasia with the immunohistochemical evaluation of MMR-system proteins in gastric mucosa specimens. In all indefinite for dysplasia cases MMR-system proteins remained unaffected. Three MSI-positive cases (6.5 %) were detected by PCR with two low-grade dysplasia, one high-grade dysplasia cases. All identified cases were also immunohistochemically MSI-positive. Conclusion. Determination of MSI can be used as an auxiliary study within a panel of biomarkers aimed to support the decision-making of a pathologist in the alternative of “indefinite for dysplasia” or “definite dysplasia — obligate precancer”.

Association of Soy Foods With Gastric Cancer Considering Helicobacter pylori: A Multi-Center Case-Control Study.

This study aims to explore the relationship between soy food consumption and gastric cancer (GC) risk, accounting for Helicobacter pylori infection status. We analyzed data from patients with GC and healthy individuals prospectively enrolled by 6 hospitals between 2016 and 2018. Dietary intake was evaluated using questionnaires that categorized seven dietary habits and 19 food groups. Multivariate logistic regression models were applied to examine associations. Model I adjusted for various epidemiological factors, while Model II included further adjustments for H. pylori infection. Primary exposures examined were consumption frequencies of nonfermented, unsalted soy foods (soybean/tofu) and fermented, salty soy foods (soybean paste stew). A total of 5,535 participants were included, with 1,629 diagnosed with GC. In Model I, the frequency of soybean/tofu consumption was inversely related to GC risk; adjusted odd ratios (aORs) were 0.62 (95% confidence interval [CI], 0.48-0.8), 0.38 (95% CI, 0.3-0.49), 0.42 (95% CI, 0.33-0.53), and 0.33 (95% CI, 0.27-0.42) for 1 time/week, 2 times/week, 3 times/week, and ≥4 times/week. Consumption of 2 servings/week of soybean paste stew showed the lowest GC association, forming a V-shaped curve. Both low (aOR, 4.03; 95% CI, 3.09-5.26) and high serving frequencies of soybean paste stew (aOR, 2.23; 95% CI, 1.76-2.82) were associated with GC. The association between soy foods and GC in Model II was similar to that in Model I. The soy food-GC associations were consistent across sexes in Model I. Nonetheless, the positive correlation between frequent consumption of soybean paste stew (≥5 times/week) and GC was more pronounced in women (aOR, 7.58; 95% CI, 3.20-17.99) compared to men (aOR, 3.03; 95% CI, 1.61-5.88) in Model II. Subgroup analyses by H. pylori status and salty diet revealed a consistent inverse relationship between soybean/tofu and GC risk. In contrast, soybean paste stew showed a V-shaped relationship in H. pylori-positive or salty diet groups and no significant association in the H. pylori-negative group. Soybean/tofu intake is consistently associated with a decreased risk of GC. However, the relationship between soybean paste stew consumption and GC risk varies, depending on H. pylori infection status and dietary salt intake. ClinicalTrials.gov Identifier: NCT03046745.

Gastric Mucosal Status and Risk of Gastric Cancer in High-Risk Individuals: A Population-Based, Multicenter Prospective Study in China.

This study explored the distributions of gastric mucosal status and their links to gastric cancer within urban high-risk individuals in China. From 2014 to 2015, a questionnaire survey was administered among individuals aged 40 to 69 years, residing for over 3 years in seven selected cities across China. Utilizing the questionnaire data, high-risk individuals for gastric cancer were screened. These identified high-risk individuals were invited to undergo endoscopy, followed by pathological examinations conducted for those with suspicious lesions. Prior cancer patients and those newly diagnosed with gastric cancer were excluded, and the remaining endoscopic participants were prospectively followed up until December 2021. The prospective study followed 8911 individuals at high risk of gastric cancer for a median duration of 6.77 years. The incidence density of gastric cancer was 58.55 per 100,000 person-years. At baseline, the distributions of subjects across normal gastric mucosa, gastritis/ulcer/polyp, atrophic gastritis/intestinal metaplasia, and intraepithelial neoplasia groups were 47.09%, 36.27%, 9.57%, and 7.07%, respectively. Compared with normal gastric mucosa, the hazard ratios (HRs) for gastric cancer in the other groups were 0.89 [95% confidence interval (95%CI): 0.38-2.08], 1.52 (95%CI: 0.50-4.66), and 4.63 (95%CI: 1.98-10.82). When using the 40-54 age group as the reference, the HR for 55-69 age group was 3.49 (95%CI: 1.52-7.98). Among high-risk individuals with gastric cancer, the proportions of individuals exhibiting different gastric mucosal status inversely correlated with the severity of mucosal lesions, whereas the risk of gastric cancer progressively escalated with the increasing severity of mucosal lesions and advancing age.

Association of miR-499 rs3746444, miR-149 rs2292832 polymorphisms and their expression levels with helicobacter pylori-related gastric diseases and Traditional Chinese Medicine syndromes.

To provide an objective experimental basis for the gastric mucosa pathological evolution and the transformation of different Traditional Chinese Medicine (TCM) syndromes in helicobacter pylori (H. pylori)-related gastric diseases (HPGD) patients, based on the combination of TCM syndrome differentiation, molecular biology and histopathology. A total of 203 participants were enrolled in this study. The expressions of miR-499/miR-149 and H. pylori infection in the gastric tissues from all participants were detected. The genotyping for miR-499 rs3746444 and miR-149 rs2292832 was performed. In H. pylori positive subjects, the proportion of precancerous gastric lesions (PGL) in liver-stomach disharmony syndrome (LSDS) group was higher than in spleen Qi deficiency syndrome (SQDS) group (P <0.001); The proportion of gastric cancer (GC) in SQDS group was higher than in spleen-stomach damp-heat syndrome (SSDHS) group and LSDS group (all P <0.001). We also found C allele of miR-149 rs2292832 was linked to lower risk of gastric atrophy [miR-149 rs2292832 C vs T: adjusted odds ratio = 0.207; 95% confidence interval (0.043-0.989); P = 0.048]. Compared with healthy control (HC) group, the expression of miR-499 was significantly increased in GC group, while the expression of miR-149 was significantly decreased in chronic inflammation group, PGL group and GC group (all P < 0.05). Test for trend showed that GC risk was on a rising trend with the increasing expression of miR-499 and decreasing expression of miR-149 (both P for trend < 0.05). The C allele of miR-149 rs2292832 may be a protective factor for gastric mucosal atrophy. H. pylori may participate in the evolution of benign to malignant gastric mucosa lesions by inducing the overexpression of miR-499 and down regulation of miR-149. In addition, patients with H. pylori infection combined SQDS or LSDS may have higher risk of gastric mucosal malignant lesions.

Association Between Type 1 Diabetes Mellitus and Incident Gastrointestinal Cancer in Korean Population: A Nationwide Retrospective Cohort Study.

The age-standardised incidence ratio of gastrointestinal cancers in type 1 diabetes (T1D) patients has been reported to be higher than that in the general population. After adjusting for shared risk factors, we aimed to explore the association between T1D and gastrointestinal cancer and examine how this relationship varies by age and sex. This retrospective cohort study included 268,179 participants from the Korean National Health Insurance Service-National Sample Cohort. The primary outcome is the incident of gastrointestinal cancers, based on diagnostic codes. Multivariate Cox regression analyses were performed to assess the association between T1D and gastrointestinal cancers. Of the 268,179 participants, 2681 had T1D at baseline and were followed for 12.98 (± 2.92) years. Compared with non-T1D, T1D patients had a significantly increased risk of all gastrointestinal cancer (adjusted hazard ratio [aHR]: 1.403, 95% confidence interval [CI]: 1.253-1.573). T1D patients increased risks of oesophageal cancer (aHR: 1.864, 95% CI: 1.038-3.349), gastric cancer (aHR: 1.313, 95% CI: 1.066-1.616), colon cancer (aHR: 1.365, 95% CI: 1.110-1.678), liver cancer (aHR: 1.388, 95% CI: 1.115-1.727), and pancreatic cancer (aHR: 1.716, 95% CI: 1.182-2.492). The consistency of this association persisted among both male and female, with its strength increasing with older age. The risk of gastrointestinal cancer was significantly increased in T1D patients. Older male T1D patients exhibit a higher risk, suggesting the need for targeted attention in their care.

Implementation of the updated Sydney system biopsy protocol improves the diagnostic yield of gastric preneoplastic conditions: Results from a real-world study

BackgroundThe updated Sydney system biopsy protocol (USSBP) standardizes the sampling of gastric biopsies for the detection of preneoplastic conditions (e.g., gastric intestinal metaplasia [GIM]), but the real-world diagnostic yield is not well-described. AimTo determine whether regular application of USSBP is associated with higher detection of chronic atrophic gastritis (CAG), GIM and autoimmune gastritis (AIG). MethodsWe performed a real-world retrospective study at an academic urban tertiary hospital in Chile. We manually reviewed medical records from consecutive patients undergoing esophagogastroduodenoscopy (EGD) from January to December 2017. Seven endoscopists who performed EGDs were categorized into two groups (USSBP ‘regular’ and USSBP ‘infrequent’) based on USSBP adherence, using minimum 20% adherence as the prespecified threshold. Multivariable logistic regression models were used to estimate the odds ratios (aOR) and 95% confidence intervals (CI) for the association between endoscopist groups and the likelihood of diagnosing CAG, GIM or AIG. Results1206 patients were included in the study (mean age: 58.5; 65.3% female). The USSBP regular group demonstrated a higher likelihood of detecting CAG (20% vs. 5.3%; aOR 4.03, 95%CI: 2.69–6.03), GIM (12.2% vs. 3.4%; aOR 3.91, 95%CI: 2.39–6.42) and AIG (2.9% vs. 0.8%; aOR 6.52, 95%CI: 1.87–22.74) compared to infrequent group. Detection of advanced-stage CAG (Operative Link for Gastritis Assessment stage III/IV) was significantly higher in the USSBP regular vs. infrequent group (aOR 5.84, 95%CI: 2.23–15.31). ConclusionsRoutine adherence to USSBP increases the detection rates of preneoplastic conditions, including CAG, GIM and AIG. Standardized implementation of USSBP should be considered in high gastric cancer risk populations.

Impacts of Matrix Metalloproteinase-8 Genotypes, Smoking, Alcohol Drinking, and Helicobacter Pylori Infection on Gastric Cancer.

In gastric cancer (GCa) tissues, mRNA expression of matrix metalloproteinase-8 (MMP-8) is notably reduced compared to healthy tissues. Furthermore, abnormally low or elevated serum levels of MMP-8 have been linked to a significantly poor prognosis. The involvement of MMP-8 genotypes in susceptibility to GCa remains underexplored. We aimed to assess the influence of MMP-8 genotypes on GCa susceptibility and their potential interactions with smoking, alcohol consumption, and Helicobacter pylori (H. pylori) infection. The study utilized polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) to analyze MMP-8 rs11225395, rs34009635, and rs35866072 genotypes in 161 GCa patients and 483 controls. No statistically significant difference was detected in the distribution of genotypic (p for trend=0.3635) or allelic (p=0.1954) frequencies of MMP-8 rs11225395. Under a dominant model, combined CT+TT genotypes showed no association with GCa risk [odds ratio (OR)=0.77, 95% confidence interval (95%CI)=0.54-1.10, p=0.1852]. Similarly, no association was observed for MMP-8 rs34009635 or rs35866072. Importantly, individuals with the MMP-8 rs11225395 CC genotype demonstrated a significant increase in GCa risk when exposed to smoking (OR=4.04, 95%CI=2.28-7.16, p=0.0001), alcohol consumption (OR=2.83, 95%CI=1.64-4.89, p=0.0002), and H. pylori infection (OR=3.53, 95%CI=2.12-5.90, p=0.0001). The findings indicate that individuals carrying the MMP-8 rs11225395 CC genotype have increased susceptibility to GCa, especially when combined with risk factors, such as smoking, alcohol consumption, and H. pylori infection. These results suggest that MMP-8 genotype-based preventive strategies, including lifestyle alterations and targeted infection treatments, may be valuable in mitigating GCa development.

Mutational signatures in 175 Chinese gastric cancer patients.

Gastric cancer (GC), a molecularly heterogeneous disease, is the third leading cause of cancer death worldwide. The majority of GC cases worldwide occur in East Asia, predominantly China. Mutational Signature Framework offers an elegant approach to identify mutational processes present in tumors. To identify mutational signature patterns, we conducted whole exome sequencing (WES) analysis in Chinese patients with GC. Mutect2 and MutsigCV were used to identify significantly mutated genes in 175 Chinese GC cases using paired tumor-normal tissues. We investigated mutational signatures using Catalogue of Somatic Mutations in Cancer (COSMIC) Version 2 (V2) and Version 3 (V3). We identified 104 mutated genes with P < 0.01. Seven genes (OR6B1, B2M, ELF3, RHOA, RPL22, TP53, ARIDIA) had q < 0.0001, including six previously associated with GC. Mutational signatures (COSMIC-V3) observed include 14 single base substitutions (SBS), one doublet base substitution (DBS) Signature A, and one InDel (ID2). The most frequent SBS signatures (SBS05, SBS01, SBS15, SBS20, SBS40) were also observed in 254 White GC cases from The Cancer Genome Atlas (TCGA) Project. However, SBS01 and SBS20 showed significant differences between Whites vs. All Asians (19.3% vs. 11.3% for SBS 1 (P = 0.012) and 11.4% vs. 5.9% for SBS20 (P = 0.025), respectively). Using COSMIC V2, signatures 6, 15, and 1 were the most frequent in Chinese GC cases. Further, most Chinese GC cases carried multiple signatures. This effort represents the most detailed mutational signatures analysis of GC cases from China to date. Results hold promise for new insights in understanding risk and prognosis factors in GC.

Opportunities for Helicobacter pylori Eradication beyond Conventional Antibiotics.

Helicobacter pylori (H. pylori) is a bacterium known to be associated with a significant risk of gastric cancer in addition to chronic gastritis, peptic ulcer, and MALT lymphoma. Although only a small percentage of patients infected with H. pylori develop gastric cancer, Gastric cancer causes more than 750,000 deaths worldwide, with 90% of cases being caused by H. pylori. The eradication of this bacterium rests on multiple drug regimens as guided by various consensus. However, the efficacy of empirical therapy is decreasing due to antimicrobial resistance. In addition, biofilm formation complicates eradication. As the search for new antibiotics lags behind the bacterium's ability to mutate, studies have been directed toward finding new anti-H. pylori agents while also optimizing current drug functions. Targeting biofilm, repurposing outer membrane vesicles that were initially a virulence factor of the bacteria, phage therapy, probiotics, and the construction of nanoparticles might be able to complement or even be alternatives for H. pylori treatment. This review aims to present reports on various compounds, either new or combined with current antibiotics, and their pathways to counteract H. pylori resistance.
