OBJECTIVE: to assess the ability of Pap smear and hybrid capture II (HCII) to detect clinically significant cervical lesions (CIN2/3) in women referred to hospital due to atypical squamous cells of unknown significance (ASCUS) or low-grade squamous intraepithelial lesions (LSIL). METHODS: a cross-sectional study comprising 161 women referred to the Taubaté University Hospital due to ASCUS/LSIL, between August 2000 and September 2002. All women responded to a questionnaire regarding sociodemographic and reproductive characteristics and were subjected to gynecological examination with specimen collection for Pap test and HCII, along with colposcopy and eventual cervical biopsy. The relationship between HCII results and age, use of condom, oral hormonal contraception, and smoking were evaluated by the chi-square test. The sensitivity, specificity, positive and negative predictive values of both Pap test and HCII were calculated. All calculations were performed within 95% confidence intervals. RESULTS: sixty-seven percent of the women that tested positive for HPV were less than 30 years old. Pap smear and HCII showed the same 82% sensitivity in detecting CIN2/3 when the threshold for a positive Pap result was ASCUS, LSIL or HSIL. Pap smear specificity and positive predictive values were substantially increased when only HSIL results were considered as positive (from 29 to 95% and 12 to 50%, respectively). These figures were superior to those of HCII, but at the expense of an expressive loss of sensitivity (from 82% to 41%). CONCLUSIONS: our results substantiate the potential of HCII in detecting CIN2/3 among women referred due to ASCUS/LSIL.

PURPOSE: to evaluate the detection of high oncogenic risk human papillomavirus DNA (HPV-DNA) immediately before and 4±1.25 months after large loop excision of the transformation zone (LLETZ) in the treatment of cervical intraepithelial neoplasia (CIN). METHODS: in this clinical prospective study, 78 patients submitted to LLETZ from February to December 2001 were enrolled. All patients were submitted to colposcopic evaluation and had Pap smear and hybrid capture II (HC II) specimens collected immediately before LLETZ and four months after the procedure. Statistical analysis was made through odds ratio (OR) calculations with 95% confidence interval (95% CI). RESULTS: before excision, 67 (86%) women had positive HC II for high oncogenic risk HPV-DNA, while four months afterwards only 22 (33%) maintained positive HC II results. Positive results of HPV-DNA after treatment were not associated with previous viral load, compromised margins in the surgical specimen or age. Four months after the procedure, detection of HPV-DNA was significantly associated with cytological abnormalities (OR = 4.8; CI 95%: 1.7-13.7) but not with histological residual disease or relapse (OR = 6.0; CI 95%: 0.8-52.3). CONCLUSION: HPV-DNA detection was significantly reduced after treatment of CIN, but was not associated with the presence of histologic residual disease or relapse.
