    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.

    PURPOSE: to evaluate the diagnostic procedures used in women with Pap smear result of atypical glandular cells. PATIENTS AND METHODS: a prospective study with 159 women with atypical glandular cells was carried out between January and December 2000. All women were submitted to a new colpocytology and to colposcopy. Directed biopsy was performed in 50 cases, endocervical curettage in 21 and conization in 75. The performance of the diagnostic procedures was described by estimating the sensitivity, specificity, predictive values and likelihood ratio, considering histological results as gold standard. RESULTS: the histological evaluation showed 51 intraepithelial squamous lesions, 29 low grade and 22 high grade. Five women presented in situ adenocarcinoma and six patients presented invasive neoplasias. Colpocytology alone showed sensitivity and specificity of 88.5 and 39%, respectively, and colposcopy alone, 74 and 42%. The association of colpocytology with colposcopy increased the sensitivity to 98.4%, with a significantly lower specificity of 10%. Endocervical curettage showed low sensitivity (25%). CONCLUSION: the presence of atypical glandular cells on colpocytology was associated with preinvasive and invasive cervical lesions in 62.2% of the cases with histological evaluation. Repeating colpocytology and performing colposcopy allowed to select the women who needed histological evaluation. Conization was an adequate procedure when examination continued to show morphologic alterations.

    OBJECTIVE: to evaluate the performance of Pap smear, hybrid capture II (HC II), and visual inspection with acetic acid in the detection of pre-invasive and invasive cervical lesions. METHODS: a total of 2281 women were submitted to a clinical exam, including Pap smear, HC II for HPV DNA detection and visual inspection with 5% acetic acid (VIA). When at least one of the tests was positive, colposcopy was performed and targeted biopsies were taken from suspicious lesions. Colposcopy was also performed in 420 women with negative results. Test performance was evaluated, using colposcopy as the gold standard, with or without biopsy. RESULTS: Pap smear, VIA and HC II were positive in 9.2, 10.9 and 17.5% of all women screened, respectively. Although at least one positive test was found in 671 women (29.4%), only 82 (3.6%) presented histologically confirmed disease (50 NIC1, 20 NIC2, 7 NIC3, and 5 invasive carcinoma). VIA and HC II sensitivities were similar and significantly higher than Pap smear. Pap smear showed better specificity than VIA and than HC II. In women with a negative Pap smear result, VIA showed better performance than HC II. CONCLUSION: Pap smear combined with VIA performed better than Pap smear combined with HC II or than Pap smear alone.

    Purpose: to determine the factors associated with the detection of a microinvasive carcinoma in the cervical cone of women with a previous colposcopically directed biopsy compatible with cervical intraepithelial neoplasia (CIN) 3 and to evaluate the proportion of involved margins. Patients and methods: we reviewed the medical records of 385 women (mean age: 39 years) submitted to cold conization or conization by high frequency surgery (HFS) with a loop during the period from January 1993 to July 2000. These procedures were indicated on the basis of a biopsy compatible with (CIN) 3. Results: the diagnosis of the cone was compatible with (CIN) 3 in 243 (63%) women and with (CIN) 2 in 13 (3%). Only 10 presented HPV/CIN 1 (3%) and eight had no residual disease in the cone. However, 101 (26%) women presented a microinvasive carcinoma in the cone and 10 (3%) presented a frankly invasive carcinoma. Age, menstrual status and number of deliveries were not related to the severity of the cone lesion. Women with oncologic colpocytology changes suggestive of invasion presented a significantly higher risk of having a microinvasive or invasive carcinoma as determined by final histology (p<0.01), although 52 of the 243 women with CIN 2 or CIN 3 in the cone also showed a suggestion of invasion at colpocytology. Among the women with CIN 2 or 3, the epithelium was white in 44%, dotted in 21%, and mosaic-like in 17%. This proportion was similar for women with a microinvasive or invasive carcinoma, with these images being detected in 37%, 23% and 21% of the cases, respectively. Involvement of the cone margins was significantly higher among women submitted to HFS (49%) than among those submitted to cold conization (29%). Conclusion: the absence of independent clinical and colposcopic factors associated with the detection of a microinvasive carcinoma in women submitted to conization on the basis of a biopsy compatible with (CIN) 3 justifies the conical excision of the squamocolumnar junction in high grade cervical lesions.

    PURPOSE: to investigate women’s age at their first sexual intercourse and its correlation with their present age, human papillomavirus (HPV) infection and cytological abnormalities at Pap smear. METHODS: women from the general population were invited to be screened for cervical cancer and pre-malignant lesions. After answering a behavior questionnaire, they were submitted to screening with cervical cytology and high-risk HPV testing with Hybrid Capture 2 (HC2). This report is part of the Latin American Screening (LAMS) study, that comprises centers from Brazil and Argentina, and the data presented herein refer to the Brazilian women evaluated at the cities of Porto Alegre, São Paulo and Campinas. RESULTS: from 8,649 women that answered the questionnaire, 8,641 reported previous sexual activity and were included in this analysis. The mean age at the interview was 38.1±11.0 years and the mean age at the first sexual intercourse was 18.5±4.0 years. The age at the first sexual intercourse increased along with the age at the interview, i.e., younger women reported they had begun their sexual life earlier than older women (p<0.001). From the total of women who had already begun having sexual intercourse, 3,643 patients were tested for high-risk HPV infection and 17.3% of them had positive results. In all the centers, it became clear that the women with the first sexual intercourse at ages below the mean age of all the population interviewed presented higher rates of HPV infection (20.2%) than the women with the first sexual intercourse at ages above the mean (12.5%) - Odds Ratio (OR) 1.8 (IC95% 1.5-2.2;p<0,001). According to the cytology, the women with first sexual intercourse at ages under the mean, presented higher percentage of abnormal cytology > or = ASC-US (6.7%) than the women with the first sexual intercourse at ages above the mean (4.3%) - OR 1.6 (IC95% 1.3-2.;p<0.001). CONCLUSIONS: the high-risk HPV infection and cytological abnormalities identified during the asymptomatic population screening were significantly associated to the women’s age at the first sexual intercourse. Additionally, we have also identified that the women’s age at the first sexual intercourse has decreased during the last decades, suggesting an important contribution to the increase of HPV infection and the subsequent cervical lesions.
