高危型HPV E6/E7 mRNA与宫颈癌相关性分析

摘要

Objective To investigate the correlation between the positive rate of high risk human papillomavirus (HPV) mRNA E6/E7 and cervical cancer,and provide evidence for the prevention and treatment of cervical cancer.Methods A total of 100 cervical cancer cases and 100 healthy controls were selected in our hospital from January 2015 to December 2015.The fluorescence quantitative PCR and pathological examination on HPV E6/E7 mRNA were carried out.The correlation between HPV E6/E7 mRNA and cervical squamous epithelial lesions were analyzed.Results In case group,the positive rate ofHPV E6/E7 mRNA was 76.0％ (76/100).In control group,the positive rate was 13.0％ (13/100).The positive rate in case group was significantly higher than that in control group,and the difference was statistically significant (x2=24.522,P＜0.001).The positive predictive value and negative predictive value of the two groups were compared,and the difference was not significant (P＞0.05).The positive rate of HPV E6/E7 mRNA was significantly higher than high-grade squamous intraepithelial lesion (SIL) rate (26.1％),low-grade SIL rate (17.6％) and atypical squamous cell hyperplasia rate (6.7％),the difference was statistically significant (x2=7.615,P=0.001;x2=9.114,P=0.001;x2=18.241,P＜0.001).Conclusions The detection rate ofHPV E6/E7 mRNA in cervical cancer patients was high.And with the increased severity of cervical squamous epithelial lesions,the positive rate of HPV E6/E7 mRNA increased.%目的 探讨高危型HPV E6/E7 mRNA检出率与宫颈癌的相关性,为临床防治宫颈癌提供依据.方法 选择2015年收治的100例宫颈癌患者为A组,同期100例健康体检者为B组,采用荧光定量PCR检测入组患者高危型HPV E6/E7 mRNA和病理学检查,比较两组患者HPV E6/E7感染率和荧光定量PCR检查效率,分析HPV E6/E7感染与宫颈鳞状上皮病变的相关性.结果 A组阳性76例,阳性率为76.0％;B组阳性13例,阳性率为13.0％;A组阳性率高于B组,差异有统计学意义(x2=24.522,P＜0.001).两组阳性预测值和阴性预测值比较,差异无统计学意义(P＞0.05).宫颈癌患者HPV E6/E7 mRNA阳性率(76.0％)高于高度宫颈鳞状上皮病变者(26.1％)、低度宫颈鳞状上皮病变者(17.6％)和非典型鳞状上皮细胞者(6.7％),差异有统计学意义(x2=7.615,P=0.001;x2=9.114,P=0.001;x2=18.241,P＜0.001).结论 宫颈癌患者HPVE6/E7mRNA检出率高,且随宫颈鳞状上皮病变加重,其HPV E6/E7 mRNA阳性率越高.
