Gender of a fetus is associated with maternal hormonal milieu and may therefore modify maternal risk of ovarian cancer following a birth. We evaluated the relation between gender of offspring and maternal risk of epithelial ovarian cancer in a large case-control study nested within a nationwide cohort. Cohort members were identified in the Swedish Fertility Register. Cases of invasive epithelia...

Deregulation of the transforming growth factor-β (TGFβ) signaling pathway in epithelial ovarian cancer has been reported, but the precise mechanism underlying disrupted TGFβ signaling in the disease remains unclear. We performed chromatin immunoprecipitation followed by sequencing (ChIP-seq) to investigate genome-wide screening of TGFβ-induced SMAD4 binding in epithelial ovarian cancer. Followi...

BACKGROUND The aim of this study was to evaluate HE4, CA125 and ROMA in the preoperative differentiation benign ovarian diseases from epithelial ovarian cancer depending on the menopausal status. METHODS In order to estimate markers' concentrations in the serum of women with benign ovarian disease (n = 128) and with epithelial ovarian carcinoma (n = 96) the electrochemiluminescence (ECLIA) te...

According to population statistics in Japan, approximately 3,800 women die of ovarian -cancer annually, and approximately 6,000 are affected by this disease. Ovarian cancer is -referred to as a "silent tumor", since patients have few subjective symptoms and by the time symptoms are observed, the cancer has progressed to Stage III or IV in about half of the patients. The basic treatment for adva...

PURPOSE SHP2 has roles in a variety of signal transduction pathways and in many important cellular processes, including proliferation, differentiation, movement regulation, and apoptosis. In addition, SHP2 expression is closely associated with multiple types of malignancies. In this study, we examined the role of SHP2 in epithelial ovarian cancer. PATIENTS AND METHODS SHP2 expression in cance...

OBJECTIVE To examine the correlation among the preoperative serum levels of five biomarkers presumed to be useful for early detection of epithelial ovarian cancer and evaluate the relationships between serum levels of these five biomarkers and epithelial ovarian cancer stage. METHODS We analyzed 56 newly diagnosed epithelial ovarian cancer patients. Preoperative serum levels of leptin, prolac...

The aim of this study was to evaluate serum human epididymis protein 4 (HE4) concentrations for the diagnosis and preoperative prediction of optimal debulking in epithelial ovarian cancer. The concentrations of serum HE4 and CA125 in 180 epithelial ovarian cancer patients, 40 benign ovarian tumor patients and 40 healthy female subjects were determined using enzyme-linked immunosorbent assays (E...

Lewis y is a difucosylated oligosaccharide carried by glycoconjugates on the cell surface. Elevation of Lewis y is frequently observed in epithelial-derived cancers. This study aimed to detect the expression and clinical significance of the Lewis y antigen and TGF-β1 (transforming growth factor β1) in ovarian epithelial tumors, and to evaluate the correlation between them. Immunohistochemical s...

Ovarian epithelial cancer is the most lethal gynecologic malignancy. The high mortality is attributed to the fact that most cases typically present in late stage when ovarian cancer (OC) has already spread beyond the ovary. Ovarian epithelial cancer cells are shed into intraperitoneal ascites and easily disseminate throughout the peritoneal cavity with preferential metastasis to the omentum, pe...

BACKGROUND The incidence of ovarian cancer is thought to be increasing in developing countries and little is known about the pattern and incidence of this disease in South-East Nigeria. AIMS The objectives of the study were to determine the incidence, describe the pattern and management of ovarian cancer at a tertiary medical center in Enugu South East Nigeria. MATERIALS AND METHODS This wa...
