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: Analisar a história de rastreamento citológico anterior em mulheres que apresentaram alterações citológicas e confirmação histológica para câncer cervical. MÉTODOS: Estudo transversal com 5.485 mulheres (15-65 anos) que se submeteram a rastreamento para o câncer cervical entre fevereiro de 2002 a março de 2003, em São Paulo e Campinas, SP. Aplicou-se questionário comportamental e foi feita a coleta da...

We compared the performance of the Whole, Turret and Step techniques of 100% rapid rescreening (RR) in detection of falsenegatives in cervical cytology. We tested RR performance with cytologists trained and among those without training. We revised 1,000 consecutive slides from women participating in an ongoing international screening trial. Two teams of experienced cytologists performed the RR techniques: one t...
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...
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 ...
This study was designed to analyze the cross-sectional comparison of the p16 INK4A and Ki-67 immunocytochemical expression in negative and equivocal (atyp-ical squamous cells of undetermined significance (ASC-US)) liquid-based cytology (LBC) samples testing positive for high-risk human papillomavirus (HPV) types with HC2 assay or polymerase-chain reaction (PCR). A series of 199 consecutive LBC speci-mens derive...
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, ...
