Many studies have investigated the association between CYP1A1 rs1048943 and rs4646903 polymorphisms and laryngeal cancer risk, but their results have been inconsistent. The PubMed and CNKI were searched for case-control studies published up to 01 July 2015. Data were extracted and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated. In this meta-analysis, we assessed 10 published studies involving comprising 748 laryngeal cancer cases and 1558 controls of the association between CYP1A1 rs1048943 and rs4646903 polymorphisms and laryngeal cancer risk. For CYP1A1 rs1048943 of the homozygote G/G and G allele carriers (A/G + G/G) versus A/A, the pooled ORs were 1.77 (95% CI = 1.28-2.81, P = 0.007 for heterogeneity) and 1.86 (95% CI = 1.45-2.40, P = 0.000 for heterogeneity). For CYP1A1 rs4646903 of the homozygote G/G and G allele carriers (A/G + G/G) versus A/A, the pooled ORs were 1.53 (95% CI = 1.31-2.21, P = 0.012 for heterogeneity) and 1.33(95% CI = 1.04-1.71, P = 0.029 for heterogeneity). In the stratified analysis by ethnicity, the significantly risks were found among Asians for both the G allele carriers and homozygote G/G. However, no significant associations were found in Caucasian population all genetic models. These results from the meta-analysis suggest that CYP1A1 rs1048943 and rs4646903 polymorphisms contribute to risk of laryngeal cancer among Asian populations.
许多研究调查了CYP1A1基因rs1048943和rs4646903多态性与喉癌风险之间的关联,但其结果并不一致。检索了PubMed和中国知网中截至2015年7月1日发表的病例对照研究。提取数据并计算合并比值比(OR)及其95%置信区间(CI)。在这项荟萃分析中,我们评估了10项已发表的研究,这些研究共纳入748例喉癌病例和1558例对照,分析CYP1A1基因rs1048943和rs4646903多态性与喉癌风险之间的关联。对于CYP1A1基因rs1048943,纯合子G/G以及G等位基因携带者(A/G + G/G)与A/A相比,合并OR分别为1.77(95%CI = 1.28 - 2.81,异质性P = 0.007)和1.86(95%CI = 1.45 - 2.40,异质性P = 0.000)。对于CYP1A1基因rs4646903,纯合子G/G以及G等位基因携带者(A/G + G/G)与A/A相比,合并OR分别为1.53(95%CI = 1.31 - 2.21,异质性P = 0.012)和1.33(95%CI = 1.04 - 1.71,异质性P = 0.029)。在按种族进行的分层分析中,在亚洲人中,G等位基因携带者和纯合子G/G均存在显著风险。然而,在白种人群的所有遗传模型中均未发现显著关联。这项荟萃分析的结果表明,CYP1A1基因rs1048943和rs4646903多态性与亚洲人群喉癌风险相关。
