Interleukin-10 (IL-10) is a multifunctional cytokine with both immunosuppressive and anti-angiogenic properties and play an important role in the pathogenesis of cancer. IL-10-1082A>G polymorphism is the most extensively studied polymorphism in the IL-10 gene in cancer susceptibility. To date, a number of case-control studies were conducted to investigate the association between IL-10-1082A>G polymorphism and cancer risk in humans. However, the association between the IL-10-1082A>G polymorphism and cancer risk is still ambiguous. In an effort to solve this controversy, we performed a meta-analysis based on 61 case-control studies, including 14,499 cancer cases and 16,967 controls. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. In the stratified analyses by specific cancer type, increased risk was found in lung cancer (OR = 3.16, 95% CI = 1.16-8.63 for GA versus AA; OR = 2.07, 95% CI = 1.16-3.70 for GG versus AA; OR = 3.17, 95% CI = 1.31-7.68 for GA/GG versus AA) and non-Hodgkin's lymphoma (OR = 1.18, 95% CI = 1.02-1.36 for GA versus AA; OR = 1.17, 95% CI = 1.02-1.35 for GA/GG versus AA). The meta-analysis also indicated that the variant genotypes were associated with a moderately increased risk in Asians in all genetic models (OR = 1.80, 95% CI = 1.17-2.76 for GA versus AA; OR = 3.32, 95% CI = 1.62-6.82 for GG versus AA; OR = 1.67, 95% CI = 1.07-2.60 for GA/GG versus AA; OR= 2.93, 95% CI = 1.43-6.03 for GG versus AA/GA). The meta-analysis suggested that the IL-10-1082A>G polymorphism was associated with increased risk of cancer in Asians and lung cancer and non-Hodgkin's lymphoma. To draw comprehensive and true conclusions, more researches with larger numbers of worldwide participants are needed to examine associations between IL-10-1082A>G polymorphism and cancer risk. 相似文献

Previous studies have investigated the association of mutS homolog 3 (MSH3) rs26279 G > A polymorphism with the risk of different types of cancers including colorectal cancer, breast cancer, prostate cancer, bladder cancer, thyroid cancer, ovarian cancer and oesophageal cancer. However, its association with cancer remains conflicting. We performed a comprehensive meta-analysis to derive a more precise estimation of the relationship between MSH3 rs26279 G > A polymorphism and cancer susceptibility. Systematically searching the PubMed and EMBASE databases yielded 11 publications with 12 studies of 3282 cases and 6476 controls. The strength of the association was determined by crude odds ratios (OR) and 95% confidence intervals (CI). Overall, pooled risk estimates demonstrated that MSH3 rs26279 G > A was significantly associated with an increased overall cancer risk under all the genetic models (GG vs. AA: OR = 1.27, 95% CI = 1.09-1.48, P = 0.002; AG vs. AA: OR = 1.10, 95% CI = 1.00-1.21, P = 0.045; GG vs. AG + AA: OR = 1.23, 95% CI = 1.06-1.42, P = 0.005; AG + GG vs. AA: OR = 1.13, 95% CI = 1.04-1.24, P = 0.006; G vs. A: OR = 1.13, 95% CI = 1.05-1.20, P = 0.001). The association was more evident for colorectal cancer and breast cancer. Moreover, the significant association was also observed in the following subgroups: Europeans, Asians, population-based studies, hospital-based studies, and studies comprising relatively large sample size (≥ 200). Our meta-analysis results demonstrated that MSH3 rs26279 G > A polymorphism is associated with an increased risk of overall cancer, especially for the colorectal cancer and breast cancer. 相似文献

The purpose of this study was to generate large-scale evidence on whether SUMO4 M55V polymorphism is associated with autoimmune and inflammatory diseases using a meta-analysis. We surveyed studies on the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases in PubMed. Meta-analysis was performed for genotypes AG versus AA, GG versus AA, GG versus AA + AG, AG + GG versus AA and G allele versus A allele in a fixed/random effect model. We identified 16 studies (11 407 cases and 10 679 controls) using PubMed search. When all groups were pooled, we detected the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases (G versus A: OR = 1.11, 95%CI = 1.03–1.19, P = 0.005; AG + GG versus AA: OR = 1.17, 95%CI = 1.06–1.28, P = 0.001; GG versus AA + AG: OR = 1.07, 95%CI = 0.94–1.21, P = 0.29; GG versus AA: OR = 1.15, 95%CI = 1.00–1.34, P = 0.06; AG versus AA: OR = 1.15, 95%CI = 1.08–1.23, P < 0.0001). In subgroup analyses, we detected the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases in Asian population (G versus A: OR = 1.18, 95%CI = 1.08–1.28, P = 0.0001; AG + GG versus AA: OR = 1.30, 95%CI = 1.16–1.45, P < 0.00001; GG versus AA + AG: OR = 1.04, 95%CI = 0.78–1.37, P = 0.80; GG versus AA: OR = 1.20, 95%CI = 0.99–1.45, P = 0.07; AG versus AA: OR = 1.32, 95%CI = 1.18–1.49, P < 0.00001). But the association was not found in Caucasian population. Meanwhile, an association of SUMO4 M55V polymorphism with autoimmune diabetes was found (G versus A: OR = 1.18, 95%CI = 1.08–1.30, P = 0.0005; AG + GG versus AA: OR = 1.22, 95%CI = 1.13–1.32, P < 0.00001; GG versus AA + AG: OR = 1.15, 95%CI = 0.96–1.38, P = 0.13; GG versus AA: OR = 1.32, 95%CI = 1.08–1.60, P = 0.006; AG versus AA: OR = 1.23, 95%CI = 1.13–1.33, P < 0.00001). This meta-analysis demonstrates the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases, especially in Asian population. 相似文献

The aim of this study was to evaluate the HSD17B1 gene polymorphisms in the risks of endometrial cancer, endometriosis and uterine leiomyoma by meta-analysis. A comprehensive electronic search was conducted in PubMed, Medline (Ovid), Embase, Weipu, Wanfang and CNKI. The pooled ORs were performed using the Revman 5.2 softerware. 8 case-control studies were included: 3 were about endometrial cancer, 4 were about endometriosis and 1 was about uterine leiomyoma. The result showed no significant association between HSD17B1 rs605059 gene polymorphisms and risks of endometrial cancer (AA vs. AG+GG: OR = 1.11, 95% CI = 0.94-1.32; AA+AG vs. GG: OR = 1.79, 95% CI = 0.42-7.52; AG vs. AA+ GG: OR = 0.87, 95% CI = 0.76-1.00; AA vs. GG: OR = 1.43, 95% CI = 0.62-3.30; A vs. G: OR = 1.00, 95% CI = 0.91-1.11) or endometriosis (AA vs. AG+GG: OR = 0.99, 95% CI = 0.75-1.32; AA+AG vs. GG: OR = 1.73, 95% CI = 0.92-3.25; AG vs. AA+ GG: OR = 1.24, 95% CI = 1.00-1.53; AA vs. GG: OR = 1.54, 95% CI = 0.79-2.97; A vs. G: OR = 1.23, 95% CI = 0.90-1.68). No association was found in a subgroup analysis based on Asian ethnicity for endometriosis. This meta-analysis suggested that HSD17B1 rs605059 polymorphisms were not associated with the risks of endometrial cancer and endometriosis. Further studies are needed to validate the conclusion and clarify the relationship between HSD17B1 rs605059 polymorphisms and the risk of uterine leiomyoma. 相似文献

The tumor necrosis factor-α (TNF-α) promoter ? 238A/G polymorphism has been repeatedly associated with systemic lupus erythematosus (SLE), but findings are not consistent across studies. Our aim was to do a meta-analysis to assess the association between TNF-α promoter ? 238A/G polymorphism and SLE. Eleven published studies of this polymorphism with SLE in different ethnic groups were identified using a Medline search. Meta-analysis was performed for genotypes AA versus GG, GA versus GG, AA versus GG+GA, GA+AA versus GG, and A allele versus G allele in a fixed/random effect model. The overall odds ratio (OR) of the AA versus GG+GA genotypes was 3.46 (95% CI = 1.35–8.83, P = 0.01), and a similar result was found in Caucasian population (OR = 4.62, 95% CI = 1.20–17.80, P = 0.03); the overall OR of the AA versus GG genotypes was 3.36 (95% CI = 1.32–8.55, P = 0.01), and a similar result was found in Caucasian population (OR = 4.29, 95% CI = 1.11–16.53, P = 0.03); the OR of the GA versus GG genotypes was 0.48 (95% CI = 0.30–0.75, P = 0.001) in Caucasian population. In conclusion, this meta-analysis demonstrates the association between TNF-α promoter ? 238A/G polymorphism and SLE, especially in Caucasian population. 相似文献

The rs36084323 A?>?G polymorphism in programmed cell death-1(PD-1) gene has been reported to be associated with cancer risk. However, the results of previous studies were inconsistent. Therefore, we performed a meta-analysis to identify the potential association, by searching the PubMed, EMBASE, Cochrane Library, and the Chinese CNKI, WANFANG and CBM databases. Data were extracted and odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the strength of the association. A total of 10 relevant studies involving 4445 cancer cases and 5126 controls were recruited. Overall, the results indicated that the PD-1 rs36084323 A?>?G polymorphism was not statistically associated with cancer risk. However, stratified analysis revealed that there was a statistically reduced cancer risk in Asians(G vs. A, OR?=?0.89, 95%CI:0.81–0.97, P?=?0.008, I2?=?48.8%; GG vs. AA, OR?=?0.79, 95% CI:0.66–0.94, P?=?0.008, I2?=?48.7%; GG/AG vs. AA, OR?=?0.87, 95%CI:0.76–0.98, P?=?0.017, I2?=?34.9%; GG vs. AG/AA, OR?=?0.85, 95%CI:0.75–0.97, P?=?0.027, I2?=?40%) and in the patients with EOC(AG vs. AA, OR?=?0.69, 95%CI:0.54–0.90, P?=?0.005, I2?=?0%; GG/AG vs. AA, OR?=?0.67, 95%CI:0.52–0.85, P?=?0.001, I2?=?0). Meta-regression showed that ethnicity (P?=?0.029) but not cancer types (P?=?0.792), source of controls (P?=?0.207) or ample size (P?=?0.585) were the sources of heterogeneity. This meta-analysis demonstrates the PD-1 rs36084323 A?>?G polymorphism is associated with decreased cancer risk in Asian, and suggests it could potentially serve as a biomarker to screen high-risk individuals. Large-scale and well-designed case-control studies are needed to enrich the evidence of this result. 相似文献

The aim of this study was to investigate the association of receptor interacting protein 2 (RIP2) single-nucleotide polymorphisms (SNPs) with susceptibility to systemic lupus erythematosus (SLE) in a Chinese population. A case-control study was performed on the SNPs rs16900617 and rs16900627 in 590 Chinese SLE patients and 660 healthy controls. These SNPs were typed by TaqMan allele discrimination assays. We found a significant association of rs16900617 G allele [odds ratio (OR) = 0.54, 95% confidence interval (CI) 0.41-0.72] and rs16900627 G allele (OR = 1.28, 95% CI 1.04-1.58) with SLE. Significant differences in genotype frequency distribution were also found in SLE and control individuals (rs16900617: AG versus AA, OR = 0.59, 95% CI 0.44-0.81; GG versus AA, OR = 0.08, 95% CI 0.01-0.65; AG + GG versus AA, OR = 0.55, 95% CI 0.41-0.75; rs16900627: AG versus AA, OR = 1.51, 95% CI 1.17-1.93; AG + GG versus AA, OR = 1.43, 95% CI 1.13-1.82). Analysis of the haplotypes revealed that two haplotypes of AG and GA were also significantly associated with SLE (OR = 1.37, 95% CI 1.11-1.70; OR = 0.60, 95% CI 0.45-0.79). Our findings suggest that the RIP2 gene polymorphisms may be associated with susceptibility to SLE in the Chinese population. 相似文献

Lack of association between DNA repair gene ERCC1 polymorphism and risk of lung cancer in a Chinese population 总被引:4,自引:0,他引:4
The ERCC1 (Excision Repair Cross Complementation Group 1) gene is involved in the nucleotide excision repair pathway. This study was designed to examine whether ERCC1 Asn118Asn (G19007A) polymorphism, which has been associated with risk of some cancers among Caucasians, may be associated with risk of lung cancer in a Chinese population. ERCC1 Asn118Asn (G19007A) genotypes were determined in DNA samples from 151 cases and 143 controls. The distribution of genotypes between cases and controls was not associated with an increased risk of lung cancer (AA versus GG: adjusted OR (odds ratio) = 1.41, 95% CI (confidence interval) = 0.76-2.59; AG versus GG: adjusted OR = 0.78, 95% CI = 0.47-1.29; and AA + AG versus GG: adjusted OR = 0.93, 95% CI = 0.73-1.19). The frequency A (0.20) of the A-allele was significantly lower among these Chinese controls than in the Caucasian control populations (A = 0.54-0.65) (All P < 0.001). No statistically significant effects of age, histological subtype or smoking were found. These findings suggest that ERCC1 Asn118Asn (G19007A) polymorphism may play a limited role for lung cancer in this Chinese population. 相似文献

BackgroundCaveolin-1 (CAV1) polymorphisms have been shown to correlated with breast cancer risk in previous studies. However, the role of CAV1 polymorphisms still remained indecisive, and dual functions of CAV1 was demonstrated in breast cancer development. Consequently, a meta-analysis to evaluate and summarize the association of the CAV1 polymorphisms with breast cancer susceptibility.Material and methodsExtensive search was performed in PubMed, Web of Science, Google scholar, EMBASE.com, CNKI and Wanfang searching platform up to March 2019. The Newcastle–Ottawa Scale (NOS) were used to evaluate the quality of each study. The Odds ratios (ORs) and the 95% confidence intervals (CIs) were analyzed to evaluate the strength of the associations in five genetic models. Inter-study heterogeneity was quantified using the I-squared (I2) test. In addition, the Egger’s test and Begg’s test were applied to evaluate the publication bias.Results4 case-control studies with 2115 cases and 2138 controls were enrolled into this analysis. There was a significant association between rs3807987 polymorphism of CAV1 and breast cancer in allele comparison (A vs. G: OR = 1.288, 95%CI = 1.162–1.428, P < 0.001), heterozygote comparison (AG vs. GG: OR= 1.422, 95%CI=1.233–1.639, P < 0.001), and dominant comparison (AA+AG vs. GG: OR=1.395, 95%CI=1.228-1.586, P < 0.001). A significant association of rs3807987 polymorphism in allele comparison (A vs. G: OR=1.238, 95%CI=1.109–1.383, P < 0.001), heterozygote comparison (AG VS. GG: OR=1.466, 95%CI=1.267–1.697, P < 0.05), and dominant comparison (AA+AG vs. GG: OR=1.384, 95%CI=1.209–1.585, P < 0.001) was also founded amongst Chinese population. A significant association between rs7804372 polymorphism and breast cancer amongst Chinese population in recessive comparison (AA vs. AT + TT: OR = 0.730, 95%CI = 0.567–0.940, P = 0.015) was identified. No significant association between breast cancer risk and rs1997623 was found.ConclusionCAV1 rs3807987 and rs7804372 polymorphisms are associated with the change of breast cancer risk. More well-designed and large studies in various populations are needed to further elaborate these associations. 相似文献

Aim: Three common polymorphisms in CD209 gene (-336A/G, -871A/G and -139G/A) have been reportedly associated with pulmonary tuberculosis risk. However, the findings from different studies were inconsistent. Therefore, we conducted a comprehensive meta-analysis to determine the association between CD209 gene polymorphisms and pulmonary tuberculosis susceptibility. Methods: The PubMed, SCI and Elsevier were searched up to April 18, 2015 for studies on the association of CD209 gene polymorphisms and pulmonary tuberculosis. Pooled odds ratio (ORs) and 95% confidence intervals (95% CIs) were calculated in a fixed-effects or random-effects model. Results: Twelve case-control studies with 3114 cases and 3088 controls were included. For -871A/G mutation, significant decreased pulmonary tuberculosis risk was observed in allele model (G vs. A: P = 0.009; OR = 0.70, 95% CI = 0.54-0.92), heterozygous model (AG vs. AA: P = 0.009; OR = 0.59, 95% CI = 0.40 to 0.88) and dominant model (AG+GG vs. AA: p =0.01; OR = 0.61, 95% CI = 0.42 to 0.89). For -336A/G polymorphism, no associations were found in all genetic models. In the subgroup analysis by ethnicity, statistical association was observed for Asians in GG vs. AA (P = 0.04; OR = 2.31, 95% CI = 1.05-5.09). No significant association was identified between -139G/A variation and pulmonary tuberculosis risk. Conclusions: This meta-analysis provides evidences that CD209 gene -871A/G is associated with decreased susceptibility to pulmonary tuberculosis in overall population; -336A/G polymorphism is associated with increased susceptibility of pulmonary tuberculosis in Asians. However, the -139G/A polymorphism is not associated with susceptibility to pulmonary tuberculosis. 相似文献

Introduction
The +49A/G polymorphism and CT60 polymorphism in the CTLA-4 gene have been extensively examined for the association with rheumatoid arthritis (RA); however, results of different studies have been inconclusive. The aim of this study is to comprehensively evaluate the genetic risks of +49A/G and CT60 polymorphisms in the CTLA-4 gene for RA.Methods
A meta-analysis was carried out to analyze the association of +49A/G and CT60 polymorphisms with RA risk.Results
A total of 30 case?Ccontrol studies in 20 articles were included in this meta-analysis. The results indicated that the variant G allele carriers (GG + GA) of +49A/G polymorphism had an 18% increased risk of RA when compared with the homozygote AA (odds ratio (OR)?=?1.18, 95% confidence interval (CI): 1.04?C1.34 for GG + AG vs. AA). In addition, the variant CT60 A allele carriers of CT60 polymorphism had a 14% decreased risk of RA when compared with the homozygote GG (OR?=?0.86, 95%CI?=?0.78?C0.95 for AA + AG vs. GG). In the subgroup analysis by ethnicity, significant elevated RA risks were associated with +49G allele carriers in Asians, but not in Europeans. However, for CT60 polymorphism, significant decreased RA risks were associated with CT60 A allele carriers in Europeans, but not in Asians.Conclusions
This meta-analysis suggested that the +49A/G and CT60 polymorphisms in the CTLA-4 gene may be risk factors for RA. 相似文献13.
The latest data show that breast, prostate, lung and colorectal cancer are the four most frequent cancers in both sexes worldwide. A number of molecular epidemiological studies have been conducted to examine the association between TNF alpha -308G/A and the risk of those cancers. However the results have been inconclusive or inconsistent. We then performed a meta-analysis to derive a precise estimation of this association. We carried out a comprehensive search in Medline, EMBASE, OVID and Chinese Biomedical Literature Database for studies using related keywords. The inclusion criteria were (i) in English or Chinese; (ii) case-control study on this association; (iii) provide usable genotype frequencies; and (iv) sufficient published data for estimating an odds ratio (OR) with 95% confidence interval (CI). ORs and 95% CIs were calculated to assess the strength of this association under homozygote comparison (AA vs GG), heterozygote comparison (GA vs GG), dominant (AA/GA vs GG) and recessive (AA vs GA/GG) genetic model comparison. Thirty case-control studies with a total number of 16,507 cases and 19,749 controls were selected for analysis. Overall, no significant association was found between this polymorphism and the risk of total four cancers (GA vs GG: OR=1.02, 95% CI=0.91-1.14, P=0.78). However, there was a significant association between this polymorphism and breast cancer risk in western populations (GA vs GG: OR=0.91, 95% CI=0.85-0.96, P=0.002). This meta-analysis also revealed that this polymorphism was not associated with susceptibility to the other three cancers. 相似文献

Survivin is an inhibitor of apoptosis protein and has a crucial role in the development of cancer. The survivin -31G>C (rs9904341) promoter polymorphism influences survivin expression and has been implicated in cancer risk. However, conflicting results have been published from studies on the association between survivin -31G>C polymorphism and the risk of cancer. To clarify the role of this polymorphism in cancer, we performed a meta-analysis of all available and relevant published studies, involving a total of 3485 cancer patients and 3964 control subjects. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the associations. The overall results indicated that the variant genotypes were associated with a significantly increased cancer risk (CC vs GG: OR=1.58, 95% CI=1.20-2.10; CC/GC vs GG: OR=1.23, 95% CI=1.00-1.51; CC vs GG/GC: OR=1.51, 95% CI=1.23-1.85). In the stratified analyses, significantly increased risk was associated with the Asian populations (CC vs GG: OR=1.67, 95% CI=1.16-2.40; CC vs GG/GC: OR=1.50, 95% CI=1.17-1.91). We also performed the analyses by cancer type, and no statistical association was observed. The results suggest that the survivin -31G>C promoter polymorphism might be associated with an increased risk of cancer, especially in the Asian populations. 相似文献

BackgroundInconsistent results have been reported from studies investigating the relationship of the interleukin-10 (IL-10) -1082 G/A polymorphism and the susceptibility of hepatocellular carcinoma (HCC). Therefore, a thorough literature review of relatedstudies was performed in this meta-analysis to examine the association of the interleukin-10(IL-10) -1082 G/A polymorphism with HCC susceptibility.MethodsElectronic databases were searched for literature on the relationship between interleukin-10(IL-10) -1082 G/A polymorphism and the risk of HCC in accordance with the inclusion and exclusion criteria. The selected studies were analyzed using the Stata 12.0 software. Finally, the strength of the associations was evaluated using the odds ratio (OR) and 95% confidence intervals (95% CI).ResultsA total of six case-control studies were enrolled into the current meta-analysis, which included a total of 911 patients and 1889 control subjects. Our data revealed no association between the IL-10 -1082 G/A polymorphism and the risk of HCC (GG vs AA:OR=0.84, 95%CI=0.57–1.25; AG vs AA:OR=0.85, 95%CI=0.70–1.05; Dominant model: OR=0.85, 95%CI=0.70–1.03; and Recessive model: OR=0.92, 95%CI = 0.64–1.32). Similarly, no association was found in sub-group analysis based on ethnicity.ConclusionThe results of our study suggest no association between IL-10 -1082 G/A polymorphism and the risk of HCC. 相似文献

Purpose
Four polymorphisms, -765G>C, -1195G>A, 8473T>C, and Val511Ala, in the cyclooxygenase-2 (COX-2) gene were identified to be associated with colorectal cancer (CRC) risk. However, the results are inconsistent. The objective of this meta-analysis was to evaluate the association between these four polymorphisms and the risk of CRC.Materials and Methods
All eligible case-control studies published up to December 2012 on the association between the four polymorphisms of COX-2 and CRC risk were identified by searching PubMed and Web of Science. The CRC risk associated with the four polymorphisms of the COX-2 gene was estimated for each study by odds ratio (OR) together with its 95 % confidence interval (CI), respectively.Results
A total of 15 case-control studies were included. Overall, no evidence has indicated that the -1195A allele, -765C allele, 8473C allele, and 511Ala allele are associated with susceptibility to CRC (-1195G>A: OR=1.11, 95 % CI: 0.82-1.51, p=0.78; -765G>C: OR=1.08, 95 % CI: 0.96-1.21, p=0.07; 8473T>C: OR=1.03, 95 % CI: 0.89-1.18, p=0.91; Val511Ala: OR=0.71, 95 % CI: 0.46-1.09, p=0.94). However, stratified analysis with ethnicity indicated that individuals with -765GC or GC/CC genotypes had an increased risk of CRC among Asian populations (GC vs. GG: OR=1.05, 95 % CI: 0.87-1.28, p=0.03; GC+CC vs. GG: OR=1.08, 95 % CI: 0.96-1.21, p=0.07).Conclusion
This meta-analysis indicated that -765G>C polymorphism was significantly associated with susceptibility to CRC in Asian populations. 相似文献18.
Many studies have reported the association between tumor necrosis factor-α (TNF-α)-238 polymorphism and digestive system cancer susceptibility, but the results were inconclusive. We performed a meta-analysis to derive a more precise estimation of the relationship between TNF-α-238 G/A polymorphism and digestive system cancer risk. Pooled analysis for the TNF-α-238 G/A polymorphism contained 26 studies with a total of 4849 cases and 8567 controls. The meta-analysis observed a significant association between TNF-α-238 G/A polymorphism and digestive system cancer risk in the overall population (GA vs GG: OR 1.19, 95 % CI 1.00–1.40, P heterpgeneity = 0.016; A vs G: OR 1.19, 95 % CI 1.03–1.39, P heterpgeneity = 0.015; dominant model: OR 1.20, 95 % CI 1.02–1.41, P heterpgeneity = 0.012). In the analysis of the ethnic subgroups, however, similar results were observed only in the Asian population, but not in the Caucasian population. Therefore, this meta-analysis suggests that TNF-α-238 G/A polymorphism is associated with a significantly increased risk of digestive system cancer. Further large and well-designed studies are needed to confirm these findings. 相似文献

BackgroundCancer of the digestive system is a common cancer and results in high mortality rates world-wide. miR-27a polymorphism has been associated with an increased risk of digestive system cancers; however, this has not been conclusively shown yet. Therefore, to clarify this, we conducted a comprehensive meta-analysis.MethodsPubMed, EMBASE, OVID and Cochrane Library databases were comprehensively searched to retrieve eligible studies published up to May 10, 2020 that referred to digestive cancers. Odds ratios and the corresponding 95 % confidence intervals (CI) were used when calculating the relationship between miR-27a rs895819 polymorphism and susceptibility to digestive cancers.ResultsA significant correlation between the miR-27a rs895819 polymorphism and the presence of digestive system cancers was found in four genetic models, which were the homozygote, dominant, recessive, and allele genetic models (GG vs AA: OR = 1.210, 95 %CI = 1.020–1.436, P = 0.029; GG + AG vs AA: OR = 1.092, 95 %CI = 1.024–1.164, P = 0.007; GG vs AG + AA: OR = 1.182, 95 %CI = 1.005–1.390, P = 0.044; G vs A: OR = 1.099, 95 %CI = 1.046–1.154, P < 0.001). Hierarchical analysis by ethnicity suggested that miR-27a rs895819 significantly increased the risk of digestive system cancers in the Asian population, but not in Caucasians. Additionally, rs895819 polymorphism was found to be significantly associated with colorectal cancer and gastric cancer.ConclusionsThe miR-27a rs895819 polymorphism may be associated with an increased risk for digestive system cancers. 相似文献
