The oocyte's primary function is to be fertilised by a spermatozoon in order to create a viable embryo. Oocyte growth and development are initiated during embryogenesis and occur in parallel to follicular development. Factors produced by the oocyte bind to receptors on follicular cells, ensuring follicular development. Oocytes begin meiosis during foetal(More)
To assess physical and psychological morbidity, sexual functioning and social and relationship satisfaction among women treated with pelvic radiotherapy. Observational (case–control) study of 199 women: 98 submitted to pelvic radiotherapy for the treatment of uterine, rectal or anal cancers and 101 without a personal history of cancer and similar(More)
Endometrial cancer is the most frequent gynecological malignancy in developed world. Cancer stem cells (CSC) are recognized as a small proportion of cells among the tumor cell population that are capable of self-renewal, aberrant differentiation, and escape homeostasis. This review aims to systematize the existing evidence of CSC of endometrial cancer and(More)
Endometrial stromal tumor is a rare mesenchymal uterine tumor. We report the case of a patient with endometrial stromal sarcoma and concomitant bilateral endometrioid adenocarcinoma of the ovary in the context of pelvic endometriosis. The patient underwent a complete cytoreduction including total hysterectomy and bilateral adnexectomy, pelvic(More)
This study concerns the evaluation of epidemiologic, clinical and laboratory parameters and the comparison of the multiple parameters between benign and malignant tumors of the ovary to establish significant criteria allowing a Malignant Risk Index to be defined. The incidence of ovarian cancer was higher among post-menopausal women with no use of oral(More)
PURPOSE OF INVESTIGATION To characterize the risk factors for abnormal cervical cytology among women with human immunodeticiency virus (HIV), and to determine the relationship between antiretroviral therapy (ART) and cytology results. MATERIALS AND METHODS Retrospective study of clinical data of 115 HIV-infected women between January 2008 and December(More)
The aim of this study was to characterize the hematogeneous spread, in vivo, of breast cancer (BC) cell lines that express hormonal receptors (HR) comparing with triple-negative (TN) BC, particularly considering the lung and liver. Female Balb/c nu nu mice (n=30) were injected with two breast cancer cell lines (MCF7 and HCC1806). Nuclear medicine imaging(More)
Breast cancer patients are stratified in 3 groups: expressing hormonal receptors (HR), which respond to therapies targeting estrogen receptors; HER2+, candidates to trastuzumab; and triple negative (TN), for which, despite its more aggressive clinical behavior, chemotherapy is therapy available. In vitro studies proved that cells subjected to specific(More)
