The present study was designed to explore whether HPV E6/E7 mRNA detection in cervical exfoliated cells can be a potential triage for HPV-positive women from a clinic-based population. Both the primary HPV testing and Papanicolaou （Pap） test were performed on all eligible HPV-positive women. HPV E6/E7 mRNA was detected by QuantiVirus HPV E6/E7 mRNA assay in cervical exfoliated cells. All HPV-positive women underwent colposcopy and further biopsy if indicated. The data were assessed by Pearson＇s Chi-squared test and the receiver operating characteristic curve. A total of 404 eligible HPV-positive women were enrolled. Positive rate of E6/E7 mRNA in high-grade squamous intraepithelial lesion （HSIL） cases was higher than that in low-grade squamous intraepithelial lesion （LSIL） or normal cases. There was no statistical difference found between mRNA and cytological testing with sensitivity （89.52% vs. 86.67%, P=0.671）, specificity （48.96% vs. 48.96%, P=1.000）, positive predictive value （39.00% vs. 38.24%, P=1.000）, and negative predictive value （92.76% vs. 90.97%, P=-0.678） for detecting ≥HSIL. HPV E6/E7 mRNA detection in cervical exfoliated cells shows the same performance as Pap triage for HSIL identification for HPV-positive women. Detection of HPV E6/E7 mRNA may be used as a new triage option for HPV-positive women.展开更多

A total of 500 patients from our hospital with ASC-US or LSIL based on cytology testing were subjected to HPV DNA and HPV E6/E7 mRNA quantitative analysis.Results: The specificity of the HPV E6/E7 mRNA test for detecting ≥high-grade squamous intraepithelial lesion(HSIL+) was statistically higher than that of the HPV DNA test(61.3% vs. 40.0%, P< 0.05), whereas there was no significant difference in the sensitivity of HPV E6/E7 mRNA test and HPV DNA test(90.0% vs. 95.0%, P > 0.05). The positive rates of HPV in the participants tested by HPV E6/E7 mRNA and HPV DNA were, respectively, 42.8%(214/500) and 62.8%(314/500), with statistical significance(P < 0.05).Conclusions: The HPV E6/E7 mRNA test was slightly less sensitivity than that of the HPV DNA test for diagnosing HSIL+ in patients with ASC-US and LSIL, but the difference was not significant, although the specificity of the former was significantly higher. HPV E6/E7 mRNA detection can effectively reduce overdiagnosis and overtreatment of patients with ASC-US and LSIL and has important clinical value in triage of patients with ASC-US and LSIL.展开更多
