Objective. This cross-sectional study was intended to assess the association between immunohistochemical analysis of p16INK4A and fragile histidine triad (FHIT) and the presence of precancerous cervical lesions. Materials and Methods. Women seen at Pe´ rola Byington Hospital, São Paulo, Brazil, with histologically confirmed cervicitis (n = 31), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2,3 (n = 3...
To evaluate the performance of a new, manual, simplified liquid-based system, DNA-Citoliq (Digene Brasil), employed under routine conditions as compared to conventional smears collected from six collaborating private laboratories. Methods: A panel of cytopathologists, who served as the gold standard diagnosis, adjudicated discordant opinions. Results: Of 3206 pairs of slides considered valid for comparison, the...
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 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...
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, ...
O HPV é causa essencial, mas não suficiente, para o desenvolvimento de lesões pré-neoplásicas e neoplásicas do colo uterino. Sua identificação é fundamental para a avaliação de risco, sendo que o método de Captura Híbrida® apresenta reconhecida eficácia para esse fim. Por sua vez, os métodos morfológicos, colposcopia, citologia e histopatologia, demonstram as alterações celulares e tissulares sugestivas da ação...
Introduction: DCS is a new liquid-base cytology system for cell collected in UCM. Objective: assess technical aspects of DCS under different pro-tocols. Methods: the first experiment was performed with 144 samples. After cervical scraping with Ayre spatula and endocervical brushing, the sample was immediately smeared on the slide and alcohol-fixed. The same brush with residual cells was used to scrap the ectoce...
