Purpose: to evaluate the efficacy of cytology and colposcopy-directed biopsy to distinguish preclinical invasive cervical carcinoma from intraepithelial lesions. Patients and Methods: 441 patients submitted to conization, hysterectomy and Wertheim-Meigs operation from 1978 to 1995 in the University Hospital "Clementino Fraga Filho", Federal University of Rio de Janeiro, Cervical Pathology Outpatient Clinic. We estimated sensitivity, specificity, predictive values, likelihood ratio and confidence intervals of each study, which were divided into four classes: 1) normal and inflammatory; 2) mild and moderate dysplasias; 3) severe dysplasia and carcinoma in situ; 4) microcarcinoma and invasive carcinoma. Biopsies were analyzed as a whole and separated in accordance with the type of the colposcopic result (satisfactory and unsatisfactory). Results: cytology has shown sensitivity of 50%, specificity of 89%, positive predictive value of 63% and negative predictive value of 82%. The likelihood ratios were 4.4 for stromal invasion diagnosis, 0.7 for severe dysplasia and carcinoma in situ, 0.1 for mild and moderate dysplasia, 2.2 for normal and inflammatory report and 0.6 for the negative results for invasion as a whole. Satisfactory colposcopic guided biopsy white a visible lesion showed sensitivity of 59%, specificity of 100% positive predictive value of 100% and negative predictive value of 83%. Likelyohood ratios were: tending to infinity for invasion, 0.5 for severe dysplasia and carcinoma in situ, zero for mild and moderate dysplasia, zero for negative and inflammatory and 0.4 for all negative results for invasion.

PURPOSE: to determine the prevalence of high-grade squamous intraepithelial lesions (HSIL) and cancer in women with cytological diagnosis of persistent ASCUS (atypical squamous cells of undetermined significance) for 6 months in the last 7 years. We also assessed if age could be a predictive factor for presence of HSIL/cancer in this group. METHODS: we included 215 cases of non-pregnant and HIV-seronegative women with cytological diagnosis of persistent ASCUS (unespecific) with at least 6 months of interval between smears. This cytological diagnosis was compared to histological diagnosis obtained by biopsy (large loop excision of the transformation zone) or cone biopsies, and considered negative when colposcopy was satisfactory without lesions or, when unsatisfactory, no lesion was detected after at least one cytological and colposcopic follow-up. RESULTS: among the 215 cases, 49.3% had negative results (CI 95%: 42.6-55.9). The prevalence of histological confirmed low-grade squamous intraepithelial lesion was 38.6% (CI 95%: 32.1- 45.1) and HSIL was 10.7% (CI 95%: 6.5-14.8). Cases of cancer were found in 1.4% of patients (CI 95%: 0-2.9). We could not find a significant difference between the prevalence of HSIL/cancer according to age group using the cutoff point of 35 years. CONCLUSION: HSIL/cancer prevalence observed in this study has shown the risk of finding this kind of lesions in about 12% of women assisted in our public health system with two cytological diagnosis of ASCUS. A higher probability of HSIL/cancer in the different age groups was not found but this result was limited by our small sample size.
