Comprehensive assessment of the association between XPC rs2228000 and cancer susceptibility based on 26835 cancer cases and 37069 controls.

ABSTRACT: Objectives In the present study, we examined available articles from online databases to comprehensively investigate the effect of the XPC (xeroderma pigmentosum complementation group C) rs2228000 polymorphism on the risk of different types of clinical cancer. Methods We conducted a group of overall and subgroup pooling analyses after retrieving the data from four databases (updated till September 2019). The P-value of association, OR (odds ratios), and 95% CI (confidence interval) were calculated. Results We selected a total of 71 eligible studies with 26835 cancer cases and 37069 controls from the 1186 retrieved articles. There is an enhanced susceptibility for bladder cancer cases under T vs. C [P=0.004; OR (95% CI) = 1.25 (1.07, 1.45)], TT vs. CC [P=0.001; 1.68 (1.25, 2.26)], CT+TT vs. CC [P=0.016; 1.26 (1.04, 1.53)], and TT vs. CC+ CT [P=0.001; 1.49 (1.18, 1.90)] compared with negative controls. Additionally, there is an increased risk of breast cancer under T vs. C, TT vs. CC and TT vs. CC+ CT (P<0.05, OR > 1). Nevertheless, there is a decreased risk of gastric cancer cases in China under T vs. C [P=0.020; 0.92 (0.85, 0.99)], CT vs. CC [P=0.001, 0.83 (0.73, 0.93)], and CT+TT vs. CC [P=0.003, 0.84 (0.76, 0.94)]. Conclusions The TT genotype of XPC rs2228000 may be linked to an increased risk of bladder and breast cancer, whereas the CT genotype is likely to be associated with reduced susceptibility to gastric cancer in the Chinese population.

Project description:BACKGROUND:Ataxia telangiectasia mutated (ATM) gene plays a key role in response to DNA lesions and is related to the invasion and metastasis of malignancy. Epidemiological studies have indicated associations between ATM rs1801516 polymorphism and different types of cancer, but their results are inconsistent. To further evaluate the effect of ATM rs1801516 polymorphism on cancer risk, we conducted this meta-analysis. METHODS:Studies were identified according to specific inclusion criteria by searching PubMed, Web of Science, and Embase databases. Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) under recessive, dominant, codominant, and overdominant models of inheritance were calculated to estimate the association between rs1801516 polymorphism and cancer risk. RESULTS:A total of 37 studies with 12,879 cases and 18,054 controls were included in our study. No significant association was found between rs1801516 polymorphism and cancer risk in overall comparisons (AA vs GG?+?GA: OR?=?0.91, 95% CI, 0.78-1.07; AA+GA vs GG: OR?=?1.00, 95% CI, 0.90-1.11; AA vs GG: OR?=?0.89, 95% CI, 0.75-1.06; GA vs GG: OR?=?1.01, 95% CI, 0.91-1.13; GG?+?AA vs GA: OR?=?1.00, 95% CI, 0.88-1.10). However, after subgroup analyses by region-specified population, significant associations were found in European (AA vs GG?+?GA: OR?=?0.79, 95% CI, 0.65-0.96, P?=?0.017; AA vs GG: OR?=?0.79, 95% CI, 0.65-0.96, P?=?0.017), South American (AA+GA vs GG: OR?=?2.15, 95% CI, 1.37-3.38, P?=?0.001; GA vs GG: OR?=?2.19, 95% CI, 1.38-3.47, P?=?0.001; GG?+?AA vs GA: OR?=?0.46, 95% CI, 0.29-0.72, P?=?0.001), and Asian (AA vs GG?+?GA: OR?=?7.45, 95% CI, 1.31-42.46, P?=?0.024; AA vs GG: OR?=?7.40, 95% CI, 1.30-42.19, P?=?0.024). Subgroup analyses also revealed that compared with subjects carrying a GG genotype, those carrying a homozygote AA had a decreased risk for breast cancer (AA vs GG: OR?=?0.76, 95% CI, 0.59-0.98, P?=?0.035), and the homozygote AA was associated with decreased cancer risk in subjects with family history (AA vs GG: OR?=?0.68, 95% CI, 0.47-0.98, P?=?0.039). CONCLUSIONS:ATM rs1801516 polymorphism is not associated with overall cancer risk in total population. However, for subgroup analyses, this polymorphism is especially associated with breast cancer risk; in addition, it is associated with overall cancer risk in Europeans, South Americans, Asians, and those with family history.

Project description:BACKGROUND:There have been several case-control studies to assess the relationship between the transforming growth factor-?1 (TGF-?1) T?+?869C (rs1982073)/C-509T (rs1800469) gene polymorphism and lung cancer in recent years; however, the results remain controversial. In this study, we investigated the potential correlation between the TGF-?1 T?+?869C/C-509T polymorphism and increased risk of lung cancer through meta-analysis. METHODS:We searched the Cochrane Library database, Embase, PubMed, Web of Science, China National Knowledge Infrastructure, and the Wanfang Data Information Service platform to identify relevant case-control studies in strict accordance with the inclusion and exclusion criteria. The odds ratio (OR) and its 95% confidence interval (95% CI) were used to evaluate the correlation between TGF-?1 gene polymorphism and lung tumor risk. Sensitivity analysis and Egger test were used to evaluate the stability of the results and possible publication bias. RESULTS:A total of 8 studies, with 3680 patients and 4018 controls, were included. The meta-analysis revealed that there was no conspicuous correlation between the TGF-?1 T?+?869C (rs1982073)/C-509T (rs1800469) variant and lung cancer in the overall population. For TGF-?1 C-509T, a significant decreased risk was identified in patients with nonsmall-cell lung cancer (NSCLC) in the analysis stratified by disease (TT vs CT?+?CC: P?=?.02, OR?=?0.49, 95% CI 0.27-0.90). However, for TGF-?1 T?+?869C, subgroup analysis showed no correlation between the T?+?869C polymorphism and lung cancer susceptibility in patients with NSCLC. In the subgroup analysis by ethnicity, no distinct association was observed between T?+?869C (rs1982073)/C-509T (rs1800469) polymorphism and lung cancer susceptibility in the Asian and Caucasian groups. Moreover, no significant association was found in the analysis of groups stratified by age, sex, and smoking history. CONCLUSION:The TGF-?1 T?+?869C (rs1982073) and C-509T (rs1800469) polymorphisms are not implicated in lung cancer susceptibility in the overall population. However, our analysis indicated that the C-509T (rs1800469) polymorphism decreases the risk of lung cancer in patients with NSCLC.
