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(More)
PD-L1 and PD-L2 constitute an important antitumor immune response. In breast cancer, their prognostic value is still to be defined. In this study, we investigate the correlation between PD-L1 and PD-L2 protein expressions with clinical and pathologic features and disease-free survival and overall survival. To assess PD-L1 and PD-L2 expressions, we conducted(More)
OBJECTIVES This is a European Commission (EC)-funded ongoing study known as the LAMS (Latin American Screening) study, where PAP smear/liquid-based cytology and screening colposcopy were compared with i) three optional screening tools [visual inspection with acetic acid (VIA), or Lugol's iodine (VILI), cervicography] and with ii) Hybrid Capture II from a)(More)
OBJECTIVE The goal of this work was to evaluate retrospectively, as quality control, the accuracy of frozen section diagnosis in ovarian tumors. METHOD We compared 243 frozen section results with the final diagnosis in paraffin sections, from cases studied from January 1994 to April 1999. RESULTS Results with the two methods were analyzed on two(More)
OBJECTIVE We compared the performance of cervical cytology and HPV DNA test in detection of residual or recurrent disease following the treatment of cervical intraepithelial neoplasia (CIN) 2/3 with loop electrosurgical excision procedure (LEEP). SUBJECTS AND METHODS A series of 107 women subjected to LEEP due to histologically confirmed CIN 2/3 between(More)
BACKGROUND Exposure of ovarian cells to estrogen, which is detoxified by glutathione S-transferases (GSTs), has been associated with epithelial ovarian cancer (EOC) development. OBJECTIVES We tested in this study whether the GSTM1, GSTT1 and GSTP1 Ile105Val polymorphisms alter the risk of EOC. MATERIALS AND METHODS Genomic DNA from 132 EOC patients and(More)
BACKGROUND The objective of this study was to evaluate the correlation between the 2001 Bethesda classification of endocervical glandular abnormalities and histological diagnosis. STUDY DESIGN A series of 155 women with endocervical glandular abnormalities on cervical smears were included: 91 with atypical glandular cells (AGC) not otherwise specified(More)
The study was designed to evaluate the prognostic importance of clinical and pathologic variables with p53 and Bcl-2 in epithelial ovarian cancer using multivariate analysis. Tumor tissues from 90 patients were analyzed immunohistochemically for p53 and Bcl-2 expression. Hazard ratios were calculated in univariate and multivariate survival analyses.(More)
Aluminum is used in a wide range of applications and is a potential environmental hazard. The known genotoxic effects of aluminum might play a role in the development of breast cancer. However, the data currently available on the subject are not sufficient to establish a causal relationship between aluminum exposure and the augmented risk of developing(More)
BACKGROUND The purpose of this study was to assess the effect of smoking on the prevalence and incidence of high-risk human papillomavirus (hr-HPV) infection and cervical intraepithelial neoplasia (CIN) in a large sample of Latin American women. METHODS The study examines baseline data on over 12,000 women included in the Latin American Screening Study(More)
