Human leukocyte antigen-G (HLA-G) is a non-classical major histocompatibility complex class Ib molecule that acts as a specific immunosuppressor. Some studies have demonstrated that human papillomavirus (HPV) seems to be involved in lower or absent HLA-G expression, particularly in cervical cancer. In this study, we performed a cross-sectional study,(More)
P53 protein function is frequently down-regulated in cervical cancer by complexing with human papillomavirus (HPV) E6 protein, leading to degradation of p53, genomic instability, and mutations. Results are controversial, however, on the prognostic value of p53 protein expression in cervical cancer. In this study, a cohort of 220 Brazilian women with FIGO(More)
The purpose of this study is to investigate the expression of p53, c-erbB-2, Ki-67, and angiogenic activity and their correlation with the clinicopathologic characteristics in a series of granulosa cell tumors of the ovary (GCTO). Eighteen GCTO cases assisted at the Department of Obstetrics and Gynecology, School of Medical Science, UNICAMP, after(More)
The etiopathogenesis of vulvar intraepithelial neoplasia (VIN III) and invasive squamous cell carcinoma are largely unknown. Since there are few studies on Brazilian patients, our purpose was to determine the frequency of human papillomavirus (HPV) infection and the expression of p53 in these lesions, and associate them with other factors such as age,(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)
This manuscript evaluates whether specific symptoms, a symptom index (SI), CA125 and HE4 can help identify women with malignant tumors in the group of women with adnexal masses previously diagnosed with ultrasound. This was a cross-sectional study with data collection between January 2010 and January 2012. We invited 176 women with adnexal masses of(More)
The c-myc protein is known to regulate the cell cycle, and its down-regulation can lead to cell death by apoptosis. The role of c-myc protein as an independent prognostic determinant in cervical cancer is controversial. In the present study, a cohort of 220 Brazilian women (mean age 53.4 years) with FIGO stage I, II and III (21, 28 and 51%, respectively)(More)
Proapoptotic molecules have been studied in epithelial ovarian neoplasms as possible indicators of the pathogenetic pathways, as targets for new therapeutic approaches, and as prognostic markers. PTEN and p53 are proteins that have many different regulatory functions, including apoptosis. We have studied their immunohistochemical expression in 70 cases of(More)
Ovarian mucinous carcinomas are uncommon, and the differential diagnosis is metastatic carcinoma mainly from the gastrointestinal tract. The aim was to verify the importance of immunohistochemical reactions and the algorithm described in literature on the basis of laterality and tumor size. Twenty-five cases identified as metastatic mucinous adenocarcinomas(More)
INTRODUCTION Cervical intraepithelial lesions due to HPV infection are common in Brazil. An understanding of the mechanisms of the interaction between HPV and host factors is still incomplete. In spite of the high incidence of cervical cancer in Brazil, such studies with Brazilian patients are scarce. The purpose of this study was to correlate the presence(More)
