Abstract:
Objective To explore the clinical value of HPV E6/E7 mRNA in screening lesions at grade CIN2 and above.Methods A total of 120 cases with CIN and suspected cervical cancer treated in our hospital from January 2014 to September 2016 were selected.According to the results of pathological examination,60 patients with CIN2,CIN3 and invasive cancer were selected as the research group.60 patients with normal CIN1 and CIN1 were selected as control group.The results of TCT,HPV DNA and HPV E6/E7 mRNA were detected and analyzed.Results In 120 patients,the total positive rate of TCT was 55%,the total positive rate of HPV DNA was 87.5%,the total positive rate of HPV E6/E7 mRNA 60.8% HPV E6/E7;control group mRNA positive rate of 78.3% was significantly higher than the positive rate of HPV DNA 36.7%(P<0.05),HPV in the study group were E6/E7 mRNA positive rate of 85.0% was significantly lower than the positive rate of HPV DNA(96.7%);HPV E6/E7 mRNA CIN1,quantitative CIN2,CIN3 and invasive carci-noma were(4 867.31 ± 694.84),(8 943.51 ± 986.23),(28 243.10 ± 10 963.21),(3 610.84 ± 412.64)copies/mL;HPV E6/E7 mRNA quantitative CIN3 values were significantly higher than that of CIN 2,CIN1 and infil-tration of cancer and the control group(P<0.05),E6/E7 mRNA CIN2 quantitative HPV the value of CIN1 was significantly higher than that of control group(P< 0.05).Two methods of detecting HPV DNA and HPV E6/E7 mRNA in the screening of CIN2 and above lesions,the sensitivity of 84.5% DNA 93.8% HPV sensitivity was higher than that of HPV E6/E7 mRNA(P<0.05)HPV E6/E7 21.6%;specificity the speci-ficity of mRNA was 53.6% higher than that of HPV DNA(P<0.05),HPV DNA.HPV ROC curve E6/E7 mRNA were 0.581 and 0.681,the difference was statistically significant(P<0.05).Conclusion The specific-ity and accuracy of HPV,E6/E7 and mRNA in detecting cervical lesions over CIN2 and above are higher than those of HPV and DNA.It is of certain diagnostic value for screening cervical lesions over CIN 2 and above.
