Abstract
Introduction Gastric cancer, characterized by high incidence and substantial disease burden, has drawn continuous attention regarding its occurrence and prognosis. Genetics plays a crucial role in influencing the prognosis of gastric cancer, and single nucleotide polymorphisms are closely associated with the occurrence, development, and prognosis of this malignant tumor. Our study aims to conduct survival analysis on patients carrying different single nucleotide polymorphisms, exploring the relationship between miRNA single nucleotide polymorphisms and the prognosis of gastric cancer. Methods Genetic data from 344 patients in Xianyou, Fujian, formed the basis of our study. We delineated the survival rate and median survival time, utilizing the log-rank test and COX regression analysis as statistical tools. Results Upon stratifying the data by sex or operation, it was discerned that the GG genotype at MSH2 rs17502941 independently posed a heightened risk for gastric cancer. Other stratification analyses suggested that the subsequent single nucleotide polymorphisms were correlated with patient prognosis: rs17502941, rs884225, rs1468063, rs7143252, and rs2271738. Discussion The outcomes of this study strongly suggest that miRNA polymorphisms significantly influence the survival time of gastric cancer patients and can serve as effective predictors for the prognosis of gastric cancer.

Zhang T, Song SS, Liu M, Park S. Association of Fried Food Intake with Gastric Cancer Risk: A Systemic Review and Meta-Analysis of Case-Control Studies. Nutrients 2023; 15:2982. [PMID: 37447308 PMCID: PMC10347084 DOI: 10.3390/nu15132982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/27/2023] [Accepted: 06/28/2023] [Indexed: 07/15/2023] Open
Abstract
Gastric cancer is one of the most prevalent cancers in Asia, and has a significant global incidence. However, the impact of fried food consumption on gastric cancer risk remains uncertain, mainly due to the limited number of participants in previous studies. To address this knowledge gap, we aimed to examine the association between fried food intake and gastric cancer incidence through a comprehensive meta-analysis. We conducted a thorough search across multiple databases, including PubMed, EMBASE, Google Scholar, Cochrane Library, China National Knowledge Infrastructure (CNKI), Korean Information Service System (KISS), and Research Information Service System (RISS), to collect studies. The newly analyzed results of the Korean Genome and Epidemiology Study (KoGES) findings were added. We assessed integrated odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) from the selected studies using Cochrane RevMan 5.0 for the meta-analysis. The quality of the studies included in the meta-analysis was assessed using the Study Quality Assessment Tool of the National Heart, Lung, and Blood Institute (NHLBI). We included 18 studies in the analysis, which compared the impact of fried food intake in gastric cancer patients (n = 5739) and healthy adults (control, n = 70,933). There was a significant positive association between gastric cancer risk and fried food intake (OR = 1.52, 95% CI = 1.23-1.87, I2 = 76%, p = 0.0001). The relationship was found to be significant in both non-East Asians (OR = 1.48, 95% CI = 1.18-1.85, I2 = 31%, p = 0.0006) and East Asians (OR = 1.54, 95% CI = 1.14-2.08, I2 = 83%, p = 0.005). In conclusion, this meta-analysis supports the notion that fried food intake is associated with an increased risk of gastric cancer in both non-Asians and Asians. Promoting a reduction in fried food consumption as a measure against gastric cancer risk is recommended.

Abstract
Hepatocellular carcinoma associated with chronic hepatitis B virus infection seriously affects human health. Present studies suggest that genetic susceptibility plays an important role in the mechanism of cancer development. Therefore, this study focused on single nucleotide polymorphisms (SNPs) of MMR genes associated with HBV-HCC. Five groups of participants were included in this study, which were healthy control group (HC), spontaneous clearance (SC), chronic hepatitis B group (CHB), HBV-related liver cirrhosis group (LC) and HBV-related hepatocellular carcinoma group (HBV-HCC). A total of 3128 participants met the inclusion and exclusion criteria for this study. 20 polymorphic loci on MSH2, MSH3 and MSH6 were selected for genotyping. There were four case-control studies, which were HC vs. HCC, SC vs. HCC, CHB vs. HCC and LC vs. HCC. We used Hardy-Weinberg equilibrium test, unconditional logistic regression, haplotype analysis, and gene-gene interaction for genetic analysis. Ultimately, after excluding confounding factors such as age, gender, smoking and drinking, 12 polymorphisms were found to be associated with genetic susceptibility to HCC. Haplotype analysis showed the risk haplotype GTTT (rs1805355_G, rs3776968_T, rs1428030_C, rs181747_C) was more frequent in the HCC group compared with the HC group. The GMDR analysis showed that the best interaction model was the three-factor model of MSH2-rs1981928, MSH3-rs26779 and MSH6-rs2348244 in SC vs. HCC group (P=0.001). In addition, we found multiplicative or additive interactions between genes in our selected SNPs. These findings provide new ideas to further explore the etiology and pathogenesis of HCC. We have attempted to explain the molecular mechanisms by which certain SNPs (MSH2-rs4952887, MSH3-rs26779, MSH3-rs181747 and MSH3-rs32950) affect genetic susceptibility to HCC from the perspectives of eQTL, TFBS, cell cycle and so on. We also explained the results of haplotypes and gene-gene interactions. These findings provide new ideas to further explore the etiology and pathogenesis of HCC.

Abstract
PURPOSE This study aimed to provide a clear comparable figure of the trends in incidence and mortality rates of esophageal cancer (EC) in Huai'an District, Huai'an City, Jiangsu Province, China, a high-risk area for EC. METHODS The data for age- and sex-specific incidence rates between 1998 and 2016, the mortality rates in 1990-2016 and the number of EC patients were obtained from Huai'an District Cancer Registry. Crude rates, Age-standardized rates (ASRs) by world standard population and truncated age-standardized rates of EC incidence and mortality were calculated. The joinpoint regression analysis was used to calculate the annual percent changes (APC), average annual percent changes (AAPC), and their 95% confidence intervals (CIs). RESULTS Overall, 20,892 new EC cases and 20,806 EC deaths were registered in Huai'an District. ASR of EC incidence from 1998 to 2016 and mortality from 1990 to 2016 were 73.32/100,000 and 60.03/100,000, respectively. The ASR illustrated that the incidence of EC had significant downward trends in total, male and female (AAPC = -4.65, -4.90, and -5.51, respectively, p <.01). The age-specific incidence and mortality rates of EC increased dramatically in people over the age of 40, and peaked in people between the ages 70-74. In the subdivisions of Huai'an District, geographical diversities in the crude incidence and mortality rates of EC were found. CONCLUSION In summary, the incidence and mortality rates of EC showed downward trends in Huai'an District. However, the burden of EC still remained serious in this high-risk area. Cost-effective methods of intervention and health education should be enhanced for improving EC prevention.

DNA Mismatch Repair Gene Variants in Sporadic Solid Cancers. Int J Mol Sci 2020; 21:ijms21155561. [PMID: 32756484 PMCID: PMC7432688 DOI: 10.3390/ijms21155561] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 07/29/2020] [Accepted: 07/30/2020] [Indexed: 12/18/2022] Open
Abstract
The phenotypic effects of single nucleotide polymorphisms (SNPs) in the development of sporadic solid cancers are still scarce. The aim of this review was to summarise and analyse published data on the associations between SNPs in mismatch repair genes and various cancers. The mismatch repair system plays a unique role in the control of the genetic integrity and it is often inactivated (germline and somatic mutations and hypermethylation) in cancer patients. Here, we focused on germline variants in mismatch repair genes and found the outcomes rather controversial: some SNPs are sometimes ascribed as protective, while other studies reported their pathological effects. Regarding the complexity of cancer as one disease, we attempted to ascertain if particular polymorphisms exert the effect in the same direction in the development and treatment of different malignancies, although it is still not straightforward to conclude whether polymorphisms always play a clear positive role or a negative one. Most recent and robust genome-wide studies suggest that risk of cancer is modulated by variants in mismatch repair genes, for example in colorectal cancer. Our study shows that rs1800734 in MLH1 or rs2303428 in MSH2 may influence the development of different malignancies. The lack of functional studies on many DNA mismatch repair SNPs as well as their interactions are not explored yet. Notably, the concerted action of more variants in one individual may be protective or harmful. Further, complex interactions of DNA mismatch repair variations with both the environment and microenvironment in the cancer pathogenesis will deserve further attention.

Abstract
BACKGROUND Defective mismatch repair (dMMR) and microsatellite instability (MSI) correlate with gastric cancer (GC) outcome. We hypothesized that MMR genetic polymorphisms that have low-penetrant effects but may cause heterogeneous MMR capability among individuals also affect GC outcome. METHODS The polymorphisms rs1800734 in MLH1, rs2303428 and rs3732183 in MSH2, rs735943 in EXO1, and rs11797 in TREX1 were selected and analyzed in independent discovery and validation sets that included 167 and 593 patients, respectively. MSI was determined. RESULTS In both the discovery and validation sets, the rs2303428 TC + CC genotype correlated with poor overall survival (OS) in non-cardia (P < 0.05) but not in cardia GC. Multivariate models showed that for OS of patients with non-cardia GC, the rs2303428 TC + CC genotype was an independent predictor in the validation set (HR 1.54; 95% CI 1.02-2.32; P = 0.040) and had a trend to be an independent predictor in the discovery set (HR 1.70; 95% CI 0.96-3.01; P = 0.067). Furthermore, in both patient sets, fluoropyrimidines-based adjuvant chemotherapy improved OS for non-cardia patients with the rs2303428 TC + CC genotype (HR 0.14; 95% CI 0.04-0.57; P = 0.006; and HR 0.29; 95% CI 0.15-0.58; P < 0.001, respectively) but not for those with the TT genotype. The rs2303428 genotypes were not associated with MSI frequency. The rs2303428 TC + CC genotype correlated with reduced expressions for thymidylate synthetase, P-glycoprotein and ERCC1 (P < 0.05) in non-cardia GC. CONCLUSIONS The rs2303428 genotypes may predict prognosis and adjuvant chemotherapy benefit in non-cardia GC patients.

Abstract
Objective: Gastric cancer is one of the leading causes of death worldwide, with many influences contributing to the disease. The aim of this study was to identify the most important risk factors. Methods: This study was conducted in 2017 with a structured overview in the Science Directe, Scopus, PubMed, Cochrane, Web of Science (ISI) databases. In the first step, articles were extracted based on their titles and abstracts; the quality of 43 articles was evaluated using the STORBE tool. Inclusion criteria were studies carried out on human, English language (first step), year of the study and the study type (second step). Results: Finally, 1,381 articles were found, of which 1,269 were excluded in primary and secondary screening. In reviewing the references of the remaining 44 papers, 4 studies were added. Finally, 43 articles were selected for the quality assessment process. A total of 52 risk factors for gastric cancer were identified and classified into nine important categories: diet, lifestyle, genetic predisposition, family history, treatment and medical conditions, infections, demographic characteristics, occupational exposures and ionizing radiation’. Conclusion: Several environmental and genetic factors are involved in the development of gastric cancer. Regarding the role of changes in ‘diet and lifestyle’, considering appropriate nutrition and improving the level of education and awareness of people is vital for early diagnosis and timely treatment of this disease, especially in people with a family history and genetic predisposition.

Abstract
BACKGROUND Major breast cancer susceptibility genes involved in DNA repair, including BRCA1 and BRCA2, have been identified. However, mutations in these genes account for only 5-10% of identified breast cancer cases. Additional DNA repair pathway genes may also contribute to susceptibility. MATERIALS AND METHODS We investigated the association between 12 single nucleotide polymorphisms (SNPs) in mismatch repair (MMR) genes and breast cancer risk among 313 sister-sets enrolled in the New York site of the Breast Cancer Family Registry (BCFR) (n=744) using conditional logistic regression analysis. RESULTS An increase in breast cancer risk was observed for women with the MUTYH_rs3219489 variant allele (odds ratio (OR)=2.23, 95% confidence interval (CI)=1.10-4.52) and for women with the MSH2_rs2303428 variant allele (OR=1.73, 95% CI=1.00-2.99). CONCLUSION Deficiencies in DNA repair pathways, such as MMR, have implications for the onset of familial breast cancer.

Abstract
Gastric cancer (GC) is one of the most common cancers worldwide, especially in Asia. The development of GC is a multifactorial process and numerous studies have linked genetic variation to GC risk. In this study, we evaluated the effects of single nucleotide polymorphisms (SNPs) of CD226 on GC susceptibility in Chinese populations including 687 cancer patients and 936 control subjects. We found that the G allele of the rs727088A>G polymorphism in the 3'-untranslated region of CD226 was significantly associated with risk of GC using logistic regression (P<10(-3)). GC patients who harbored the rs727088G allele had significantly increased cancer risk (odds ratio=1.43, 95% confidence interval=1.23-1.67) compared with those patients harboring the rs727088A allele. Moreover, functional relevance was further performed that individuals carrying the rs727088G allele were correlated with lower expression level of CD226 than individuals carrying the rs727088AA homozygous genotype. These findings indicated that functional polymorphism rs727088A>G in CD226 might modify the susceptibility for the development of GC.

Abstract
Alopecia neoplastica is defined as hair loss secondary to a visceral malignancy that has metastasized to the scalp. The scalp is a relatively common site of cutaneous metastasis, usually presenting as a single or multiple firm scalp nodules. Alopecia neoplastica is a well-recognized but rare presentation, and its pathogenesis is incompletely understood. Atrophy of the hair follicles due to tumor invasion of the scalp plays a role in the development of alopecia. Herein, we describe a 33-year-old woman with gastric adenocarcinoma who developed alopecia neoplastica while receiving cancer chemotherapy. Scalp biopsy revealed metastatic adenocarcinoma cells interspersed between collagen bundles and around hair follicles. Immunohistochemical analysis indicated that the tumor cells originated from the primary gastric adenocarcinoma. Therefore, she was diagnosed with alopecia neoplastica due to gastric adenocarcinoma. The findings from this report may be helpful for understanding the mechanism of alopecia neoplastica.

Abstract
OBJECTIVE To explore the association among life-style, clinical examination, polymorphisms in CDH1 gene and Traditional Chinese Medicine (TCM) syndrome differentiation of gastric cancer (GC). METHODS A hospital-based population of 387 GC patients was investigated in Jiangsu province. Relevant information regarding lifestyle and clinical examination were collected by a standard questionnaire. Four known single nucleotide polymorphisms (SNPs) in CDH1 were investigated by polymerase chain reaction-ligation detection reaction methods. Statistical analysis was conducted by SPSS 16.0 software. RESULTS The results showed that meal duration and the status of glutamic pyruvic transaminase were significantly associated with TCM syndrome differentiation of GC (both P < 0.05). None of the four SNPs in the E-cadherin (CDH1) gene achieved significant differences in their distributions among the nine syndrome types of GC (both P > 0.05). However, significant differences were observed in rs13689 genotype distributions between several pairs of syndrome types of GC, suggesting that rs13689 is correlated with the syndrome differentiation of GC. CONCLUSION Integrated analysis of lifestyle, clinical examination and CDH1 gene polymorphisms can contribute to a better understanding of the GC syndrome types and may improve the efficacy of interventions by stratifying disease according to TCM criteria.

Association among polymorphisms in EGFR gene exons, lifestyle and risk of gastric cancer with gender differences in Chinese Han subjects. PLoS One 2013; 8:e59254. [PMID: 23555641 PMCID: PMC3612075 DOI: 10.1371/journal.pone.0059254] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2012] [Accepted: 02/13/2013] [Indexed: 02/06/2023] Open
Abstract
Background The epidermal growth factor receptor (EGFR) gene plays a key role in tumor survival, invasion, angiogenesis, and metastatic spread. Recent studies showed that gastric cancer (GC) was associated with polymorphisms of the EGFR gene and environmental influences, such as lifestyle factors. In this study, seven known SNPs in EGFR exons were investigated in a high-risk Chinese population in Jiangsu province to test whether genetic variants of EGFR exons and lifestyle are associated with an increased risk of GC. Methodology/Principal Findings A hospital-based case-control study was performed in Jiangsu province. The results showed that smoking, drinking and preference for salty food were significantly associated with the risk of GC. The differences of lifestyle between males and females might be as the reason of higher incidence rates in males than those in females. Seven exon SNPs were genotyped rs2227983,rs2072454,rs17337023,rs1050171,rs1140475, rs2293347, and rs28384375. It was noted that the variant rs2072454 T allele and TT genotype were significantly associated with an increased risk of GC. Interestingly, our result suggested the ACAGCA haplotype might be associated with decreased risk of GC. However, no significant association was examined between the other six SNPs and the risk of GC both in the total population and the age-matching population even with gender differences. Conclusions Smoking, drinking and preference for salty food were significantly associated with the risk of GC in Jiangsu province with gender differences. Although only one SNP (rs2072454) was significantly associated with an increased risk of GC, combined the six EGFR exon SNPs together may be useful for predicting the risk of GC.
