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
