In this study, we assessed the triage value of human papillomavirus （HPV） 16/18 genotyping in 273 patients with LSIL/CINI. HPV16/18 genotyping was performed at baseline and follow-up was at 6-monthly intervals for up to 2 years. At each follow-up, women positive for cytology or high-risk HPV （hrHPV） were referred for colposcopy. Enrollment cytology, HPV16/18 genotyping, and questionnaire-obtained factors were linked to the 2-year cumulative progression rate. Univariate and multivariate analyses were performed taking into account time-to-event with Cox proportional hazard regression. The results showed that 190 cases （69.6%） regressed, 37 （13.6%） persisted, and 46 （16.8%） progressed. HPV16/18 positivity （hazard ratio （HR）, 2.708; 95% confidence interval （CI）, 1.432-5.121; P=-0.002） is significantly associated with higher 2-year cumulative progression rate. Sub-analysis by enrollment cytology and age restricted the positive association among patients preceded by mildly abnormal cytology and aged 30 years or older. Immediate treatment is a rational recommendation for the high-risk subgroup, when good compliance is not assured.展开更多

Methods: Findings from 825 women submitted to E6/E7 RNAm survey and 422 women submitted to LGT biopsies were analyzed. Results: A larger percentage of E6/E7 in ASC-US and LSIL cytologies occurred. Negative results of RNAm expression were in accordance with negative cytologies and negative anatomopathological exam. In positive cases, the infection by a single HPV type was most prevalent, with the type 16 being the most common. Conclusions: the expression of mRNA was most prevalent in ASC-US and LSIL cytologies, comparing with the negative ones. The findings of SIN 1 biopsies were related to the positive expression of mRNA and negative cytologies;the negative expression was in agreement with negative anatomopathological exam. The infection by a HPV type was more frequent in cases of positive expression, the HPV type 16 being most frequently found. Patients with low grade intraepithelial lesion cytologies had a higher percentage of multiple infections.展开更多
