目的：评价p53基因第4外显子第72密码子G／C多态性与中国女性宫颈癌的相关性。方法检索中国知网、万方数据库、维普数据库、中国生物医学文献数据库、PubMed、EMBase、the Cochrane Library和WanFang Data数据库，收集国内外关于p53基因第4外显子第72密码子G／C多态性与中国女性宫颈癌相关性的病例对照研究文献，筛选符合纳入标准的研究，根据研究对象是否感染人乳头瘤病毒（HPV ）分为2个亚组，并对相关数据进行Meta分析。结果共纳入13篇文献，调查宫颈癌患者1780例及对照1517例。Meta分析显示对于非HPV感染亚组，具有基因型G／G、基因型 G／C 和等位基因 G的中国女性，与具有基因型 C／C （OR＝0.980，95％ CI：0.558～1.723）、基因型 G／C （OR ＝0.843，95％ CI：0.556～1.277）和等位基因 C （OR ＝1.070，95％ CI：0.789～1.449）的中国女性发生宫颈癌的风险相当；同样对于HPV感染亚组，具有基因型G／G、基因型G／C和等位基因G的中国女性，也与具有基因型C／C （OR＝0.891，95％ CI：0.213～3.722）、基因型G／C （OR＝1.351，95％ CI：0.942～1.937）和等位基因C （OR＝0.981，95％ CI：0.493～1.951）的中国女性发生宫颈癌的风险相当。所纳入文献不存在发表偏倚，本研究Meta分析结果稳定。结论目前尚未发现p53基因第4外显子第72密码子G／C单核苷酸多态性与中国女性宫颈癌的发病有关。

Objective To evaluate the association of cervical cancer and the G/C single nucleotide polymorphism at codon 72 in p53 gene exon -4 in Chinese population.Methods Literatures were searched in CNKI,VIP,CBM, PubMed,EMBase,the Cochrane Library (Issue 1,2015),WanFang Data Database (1980—2015)with computer. Results Thirteen studies involving 1 780 cervical cancer patients and 1 5 17 healthy volunteers were included.According to the situation of the HPV infection in research object,thirteen studies were divided into two subgroups.The results of meta-analyses in the subgroup of non-HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.980,95%CI:0.558 -1.723).The allele G showed no increased relative risk compared to the allele C (OR=1.070,95%CI:0.789-1.449)The results of meta-analyses in the subgroup of HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.891,95%CI:0.213 -3.722).The allele G showed no increased relative risk compared to the allele C (OR =0.981,95%CI:0.493 -1.951 ).Conclusion This meta -analysis demonstrates that G/C single nucleotide polymorphism at codon 72 in p53 gene exon-4 were not associated with cervical cancer in Chinese women.
