Cervical Cancer Risk

This meta-analysis systematically reviews the association between Toll-like receptor 9 polymorphisms and the risk of cervical cancer. Case-control studies focused on the association were collected from the PubMed, Web of Science, Cochrane Library, Embase, MEDLINE, CNKI, VIP, and Wanfang databases from inception to July 2017. We screened the studies and assessed the methodological quality of the included studies and extracted data. A meta-analysis was performed using RevMan 5.3 and Stata 12.0 software. Pooled odds ratios and 95% confidence intervals were employed to evaluate the strength of the associations between Toll-like receptor 9 polymorphisms and cervical cancer risk. A total of 9 studies comprising 3331 cervical cancer patients and 4109 healthy controls met the inclusion criteria. Of these, 8 studies contained information about G2848A (rs352140) and 4 studies contained information about −1486T/C (rs187084). Our results revealed that the associations between rs187084 and cervical cancer risk in the dominant model (p=0.002) and heterozygous model (p=0.002) were significant, with 1.30- and 1.32-fold increases in susceptibility, respectively, compared to that in the wild-type model. However, rs352140 was not related to cervical cancer regardless of whether the subgroup analysis was conducted (p>0.05). In conclusion, there is a significant correlation between rs187084 and cervical cancer risk with the minor C allele increasing the risk of occurrence of cervical cancer. However, rs352140 is not associated with the occurrence of cervical cancer.

Abstract Objective: Regulation of single nucleotide polymorphisms (SNP) in micro-RNA ( miRNA) on the host cells may be one of the most important factors influencing the occurrence of cervical cancer based on the prevalence of HPV infection and the development of cervical cancer. In order to explore the contribution of miRNA polymorphism to the occurrence and development of cervical cancer, we conducted an analytical study. Methods: We selected the polymorphisms of three widely studied miRNAs (miRNA-146a rs2910164, miRNA-499 rs3746444 and miRNA-196a2 rs11614913). Then we conducted a meta-analysis (for the first time) to investigate their susceptibility to cervical cancer. Case control studies on the correlation between these three miRNAs and cervical cancer susceptibility were investigated by searching on from Pubmed, The Cochrane Library, Embase, CBM, CNKI, Wanfang database and VIP database. Basic characteristics were recorded and meta-analysis of the case studies was performed using STATA 15.1 software. Results: The miRNA-146a rs2910164 mutation significantly reduced the risk of cervical cancer in both recessive model (OR= 0.804, 95%CI= 0.652-0.992, P= 0.042；CC vs. CG+GG) and allelic model (OR= 0.845, 95%CI= 0.721-0.991, P= 0.038；C vs. G). There was no significant correlation between miRNA -499 rs3746444 and the risk of cervical cancer. The miRNA -196a2 rs11614913 mutation was significantly associated with a reduced risk of cervical cancer in homozygous model (OR= 0.641, 95%CI= 0.447-0.919, P= 0.016；TT vs. CC), dominant model (OR= 0.795, 95%CI= 0.636-0.994, P= 0.045；CT+TT vs. CC), recessive model (OR= 0.698, 95%CI= 0.532-0.917, P= 0.01；TT vs. CC+CT), and allelic models (OR= 0.783, 95%CI= 0.643-0.954, P= 0.015；T vs. C). Conclusion: In summary, this meta-analysis shows that the mutant genotypes of miRNA -146a rs2910164 and miRNA -196a2 rs11614913 are associated with a reduced risk of cervical cancer. Therefore, they may be two gene regulatory points for the prevention of cervical cancer.

Interleukin-6 (IL-6) is a multifunctional cytokine that has been implicated in the etiology of cancer. Several case–control studies have been conducted to assess the association of IL-6 -174G>C (rs1800795) polymorphism with the risk of cervical cancer, yet with conflicting conclusions. To derive a more precise estimation of the relationship, we performed this meta-analysis updated to June 2018. A total of seven original publications were identified covering IL-6 -174G>C (rs1800795) polymorphism. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the relationship strengths. Statistically significant relationship was observed between IL-6 -174G>C polymorphism and cervical cancer risk (OR = 0.61, 95% CI: 0.40–0.94 for GG vs. CC, and OR = 0.77, 95% CI: 0.64–0.93 for G vs. C). Moreover, the significant association was found among Asians (OR = 0.46, 95% CI: 0.29–0.75 for GG vs. CC, and OR = 0.70, 95% CI: 0.57–0.89 for G vs. C); hospital-based subgroup (OR = 0.53, 95% CI: 0.38–0.72 for GG vs. CC, and OR = 0.73, 95% CI: 0.61–0.87 for G vs. C); and Hardy–Weinberg equilibrium ≤0.05 (OR = 0.56, 95% CI: 0.37–0.86 for GG vs. GC, and OR = 0.66, 95% CI: 0.47–0.93 for G vs. C). This meta-analysis showed the evidence that the IL-6 -174G>C polymorphism was a low-penetrance susceptibility variant for cervical cancer. Further large-scale case–control studies are needed to confirm these results.

Whether serum copper levels were higher in patients with cervical cancer than that in controls was controversial. Hence, we conducted the present study to explore the relationship between serum copper levels and cervical cancer. We searched PubMed, WanFang, and China National Knowledge Internet (CNKI) for relevant studies before November 30, 2017. Standardized mean difference (SMD) and 95% confidence interval (CI) were used to combine results across studies using the random-effect model. A total of 14 publications involving 747 patients with cervical cancer and 1014 controls were eligible through inclusion criteria. In comparison with controls, serum copper levels were significantly higher in patients with cervical cancer [summary SMD = 1.35; 95%CI: 0.10–2.59], with significant heterogeneity (I2 = 98.8%; P<0.001) was found. Significant association was also found among Asian populations [summary SMD = 1.39; 95%CI: 0.06–2.71]. The association was positive in subgroup analysis of population-based case–control studies (PBCC) [summary SMD = 1.64; 95%CI: 0.02–3.34], but not in hospital-based case–control studies (HBCC). Through a sensitivity analysis, we did not identify any single study to strongly influence the results of our serum copper levels and cervical cancer risk. No publication bias was found in our analysis. In conclusion, our study provided significant evidence of higher serum copper levels in patients with cervical cancer than in controls, suggesting that serum copper exposure was a risk factor on cervical cancer.

ObjectiveThis work aims to explore whether Toll-like receptor 9 (TLR9) −1486T/C and 2848G/A polymorphisms are associated with cervical cancer risk.MethodsA comprehensive electronic search of studies published from January 1999 to October 2014 was conducted in Medline (Ovid), Embase, PubMed, Wanfang, Weipu, and CNKI. The algorithm included “TLR,” “Toll-like receptor,” “polymorphism,” “variant,” “mutation,” and “cervical cancer.” Seven articles, including 9 studies, were pooled using Revman 5.2 (Cochrane Collaboration, Copenhagen, Denmark). Odds ratio (OR) was used to explore the involvement of minor allele C (C vs T and CC + CT vs TT) of TLR9 (−1486T/C, rs187084) and minor allele A (A vs G and AA + AG vs GG) of TLR9 (2848G/A, rs352140) in cervical cancer risk.ResultsToll-like receptor 9 (−1486T/C, rs187084) polymorphisms were associated with an elevated risk of cervical cancer (C vs T: OR, 1.15; 95% confidence interval [CI], 1.03–1.29; CC + CT vs TT: OR, 1.30; 95% CI, 1.11–1.53). We found no significant association between TLR9 (2848G/A, rs352140) polymorphisms and cervical cancer risk (A vs G: OR, 1.15; 95% CI, 0.87–1.54; AA + AG vs GG: OR, 1.27; 95% CI, 0.75–2.17).ConclusionsThis meta-analysis indicates that TLR9 (−1486T/C, rs187084)—but not TLR9 (2848G/A, rs352140)—may be a risk factor for cervical cancer.

The objective of this study was to conduct a meta-analysis to systematically summarize and investigate the association of miRNA-124 rs531564, miRNA-218 rs11134527, miRNA-146a rs2910164, miRNA-196a2 rs11614913, and miRNA-499 rs3746444 polymorphisms with cervical cancer. A systematic review was performed to identify relevant studies using Embase and PubMed databases. A chi-square-based Q -test combined with the inconsistency index ( I 2 ) was used to check the heterogeneity between studies. A total of six case-control studies on rs2910164 and rs11614913, 4 studies on rs3746444 and rs11134527, and three studies on rs531564 were included. No evidence of association was found between miR-146a rs2910164, miR-196a2 rs11614913, miRNA-499 rs3746444, and miR-218 rs11134527 polymorphisms and cervical cancer risk in all the genetic models. The miR-124 rs531564 polymorphism was associated with a statistically increased risk of cervical cancer in a homozygote model (CC vs. GG: OR = 2.87 , 95% CI: 1.40-5.91, P H = 0.887 ), dominant model (GC/CC vs. GG: OR = 1.38 , 95% CI: 1.07-1.80, P H = 0.409 ), and recessive model (CC vs. GC/GG: OR = 2.26 , 95% CI: 1.58-3.23, P H = 0.979 ). However, this finding should be interpreted with caution for limited samples and heterogeneity. Large-scale and well-designed studies are needed to validate our result.

BackgroundA debate exists about whether interleukin 10 (IL-10) polymorphisms (IL-10−1082G/A and IL-10−592C/A) confer additional risk for cervical cancer. To derive a more precise estimation of the relationship between IL-10 polymorphisms and cervical cancer risk, we conducted a meta-analysis of all available studies relating the −1082G/A and −592C/A polymorphisms of the IL-10 gene to the risk of developing cervical cancer.MethodsEight studies were eligible for IL-10 −1082G/A (1498 cases and 1608 controls), and 5 studies were eligible for IL-10 −592C/A (2396 cases and 1388 controls). Pooled odds ratios (ORs) were appropriately derived from fixed-effects or random-effects models. Subgroup analyses were performed by ethnicity and Hardy-Weinberg equilibrium in the controls.ResultsIn the overall analysis, no significant association between the IL-10−1082G/A polymorphism and the risk of cervical cancer was observed. In the subgroup analysis by ethnicity, IL-10 −1082A allele was associated with decreased cervical cancer susceptibility among whites (A vs G: OR, 0.39; 95% confidence interval [CI], 0.32–0.47). Studies with controls deviated from Hardy-Weinberg equilibrium showed an evident association in dominant model (GA/AA vs GG: OR, 1.73 [95% CI, 1.04–2.89]). On the other hand, with respect to −592C/A polymorphism, significantly elevated cervical cancer risk was found in the overall analysis (A vs C: OR, 1.16 [95% CI, 1.04–1.31]; AA vs CC: OR, 1.36 [95% CI, 1.00–1.84]; CA/AA vs CC: OR, 1.18 [95% CI, 1.01–1.39]; AA vs CC/CA: OR, 1.25 [95% CI, 1.01–1.55]). Stratified analysis indicated that significantly increased risks were also found among Asians in the allelic model (A vs C: OR, 1.23 [95% CI, 1.01–1.49]).ConclusionsInterleukin 10−1082 G/A polymorphism showed no effect on cervical cancer risk in the overall analysis. The genetic polymorphism in IL-10−592C/A is a risk factor for developing cervical cancer, especially for Asians.

Abstract Objective Regulation of single nucleotide polymorphisms (SNP) in micro-RNA (miRNA) on the host cells may be one of the most important factors influencing the occurrence of cervical cancer based on the prevalence of HPV infection and the development of cervical cancer. In order to explore the contribution of miRNA polymorphism to the occurrence and development of cervical cancer, we conducted an analytical study. Methods We selected the polymorphisms of three widely studied miRNAs (miRNA-146a rs2910164, miRNA-499 rs3746444, and miRNA-196a2 rs11614913). Then, we conducted a meta-analysis (for the first time) to investigate their susceptibility to cervical cancer. Case control studies on the correlation between these three miRNAs and cervical cancer susceptibility were investigated by searching on from Pubmed, The Cochrane Library, Embase, CBM, CNKI, Wanfang database, and VIP database. Basic characteristics were recorded and meta-analysis of the case studies was performed using the STATA 15.1 software. Results The miRNA-146a rs2910164 mutation significantly reduced the risk of cervical cancer in both recessive model (OR = 0.804, 95% CI = 0.652-0.992, P = 0.042; CC vs. CG+GG) and allelic model (OR = 0.845, 95% CI = 0.721-0.991, P = 0.038; C vs. G). There was no significant correlation between miRNA-499 rs3746444 and the risk of cervical cancer. The miRNA-196a2 rs11614913 mutation was significantly associated with a reduced risk of cervical cancer in homozygous model (OR = 0.641, 95% CI = 0.447-0.919, P = 0.016; TT vs. CC), dominant model (OR = 0.795, 95% CI = 0.636-0.994, P = 0.045; CT+TT vs. CC), recessive model (OR = 0.698, 95% CI = 0.532-0.917, P = 0.01; TT vs. CC+CT), and allelic models (OR = 0.783, 95% CI = 0.643-0.954, P = 0.015, T vs. C). Conclusion In summary, this meta-analysis shows that the mutant genotypes of miRNA-146a rs2910164 and miRNA-196a2 rs11614913 are associated with a reduced risk of cervical cancer. Therefore, they may be two gene regulatory points for the prevention of cervical cancer. Systematic review registration PROSPERO registration number CRD42021270079.

Objective: Some studies have recently focused on the association between TNF-α polymorphisms and cervical cancer; however, results have been inconsistent. In order to drive a more precise estimation, the present systematic review and meta-analysis is performed to investigate the relationship of the TNF-α rs1800629 and s1799724 polymorphisms with cervical cancer risk. Methods: An electronic search was conducted on PubMed, Web of Science, and Google scholar databases, for papers that describe the association between TNF-α polymorphisms and cervical cancer risk. Results: A number of 24 case-control studies in 22 publications were identified according to the inclusion criteria. The results showed that rs1800629 polymorphism was significantly associated with the increased cervical cancer risk under four genetic models (A vs. G: OR = 1.277, 95% CI: 1.104-1.477, p = 0.001; AA vs. GG: OR = 1.333, 95% CI: 1.062-1.674, p = 0.013; AG vs. GG: OR = 1.307, 95% CI: 1.064-1.605, p = 0.011; and AA+AG vs. GG: OR = 1.324, 95% CI: 1.104-1.587, p = 0.002). In stratified analysis, there was a significant association between rs1800629 polymorphism and cervical cancer risk in the subgroup of Caucasians and African, but not in Asians. However, no statistically significant association was observed between the s1799724 and cervical cancer risk under all genetic models. Furthermore, stratification by ethnicity indicated no association between the s1799724 and cervical cancer risk.Conclusion: the present meta-analysis suggests that the rs1800629 polymorphism of the TNF-α gene was significantly associated with cervical cancer risk, but not s1799724.
