AIMS: To evaluate the role of hormonal contraceptives as a risk factor of high-risk human papillomavirus (HR-HPV), cervical intraepithelial lesions (CIN) and cervical cancer in our multi-center population-based LAMS (Latin American Screening) study. METHODS: A cohort study with >12,000 women from Brazil and Argentina using logistic regression to analyze the covariates of hormonal contraception (HOC - oral, inje...

OBJETIVO: descrever a idade de início da atividade sexual (sexarca) e a sua associação com a idade das mulheres com a infecção por papilomavírus humano (HPV) e com as alterações citológicas no exame de papanicolaou. MÉTODOS: mulheres da população geral foram recrutadas para participar de um estudo de rastreamento de câncer cervical e lesões pré-malignas. Após a aplicação de questionário comportamental, foram su...

Screening for cervical Cancer in high-risk populations : DNA pap test or hybrid...

This study was designed to evaluate whether Hybrid Capture II (HC2) test alone refer women to colposcopy as appropriately as DNA Papanicolaou (Pap) test, in the context of a high-risk group of women using the recently validated DNACitoliq LBC system. Women with suspected cervical disease were included in this crosssectional study at a tertiary center in São Paulo, Brazil, for further workup. All women had cervi...

Human papillomavirus testing as an optional screening tool in low-resource sett...

Hybrid capture II (HC II) test for oncogenic human papillomaviruses (HPV) was carried out in a cohort of 4284 women at their first clinical visit. Overall prevalence of HPV was 17.1%, decreasing with age from 33.9% among women below 20 years to only 11.0% among those older than 41 years. HPV prevalence was significantly higher among current smokers (odds ratio [OR] ¼ 1.31; 95% CI 1.1–1.6), in women with two or ...

O impacto do diagnóstico citológico de atipiasi indeterminadas no sistema públi...

As alterações citológicas de significado indeterminado representam uma importante limitação diagnóstica nos programas de escrutíneo de lesões cérvico-vaginais. A introdução de métodos biomoleculares, como o sistema de captura híbrida para detecção de HPV de alto risco contribui para a otimização da conduta clínica dessas pacientes, indicando colposcopia com precisão. Objetivo: avaliar o significado de lesões de...

DCS liquid-based system is more effective than conventional smears to diagnosis...

Objective. To compare the performances of Papanicolaou test (PapTest) and of a new liquid-based cytology method, DNA-CitoliqR System (DCS), in a high-risk population, with histology confirmation. Methods. Paired specimens of exfoliated cervical cells were collected under split-sample protocol. All patients were submitted to colposcopy and a biopsy taken when any atypical transformation zone was seen. Sensitivit...

Evaluation of visual inspection with acetic acid (VIA), Lugol’s iodine (VILI), ...

Objectives: To assess the performance indicators of visual inspection with acetic acid (VIA) and visual inspection with Lugol’s iodine (VILI) in four Latin American centres participating in the ongoing Latin AMerican Screening (LAMS) study, in settings with moderate incidence of cervical disease and with poorly to moderately well-organized cervical cancer screening. Setting: Three Brazilian centres (São Paulo, ...

The present study was designed to further assess the validity of the cytological description of morphological lesions said to be related to Papillomavirus (HPV) infections in senior women. The casuistic comprised 196 cervical smears from a group of women with no clinical or morphological evidence of neoplasia, collected simultaneously with samples submitted to detection of HPV DNA by PCR in a previous study.
