OBJECTIVE Accumulated studies have investigated the prognostic significance of estrogen receptor expression in epithelial ovarian cancer, but results remain controversial. The aim of this study was to perform a meta-analysis to clarify the prognostic value of estrogen receptor expression in epithelial ovarian cancer. METHODS A systematic search was performed in PUBMED, EMBASE, and COCHRANE da...

Ovarian cancer is the fifth most common cancer among women and causes more deaths than any other type of female reproductive cancer. Currently, treatment of ovarian cancer is based on the combination of surgery and chemotherapy. While recurrent ovarian cancer responds to additional chemotherapy treatments, the progression-free interval becomes shorter after each cycle, as chemo-resistance incre...

OBJECTIVE The purpose of our study was to evaluate the diagnostic accuracy of FDG positron emission tomography (PET) in comparison with CT in detecting recurrent ovarian carcinoma and its ability to reveal small tumor recurrence. MATERIALS AND METHODS We reviewed the records of 31 consecutive patients with pathologically proven epithelial carcinoma who underwent FDG PET 1 month before second-...

Epithelial Ovarian cancer is the leading cause of cancer mortality among women all over the world. As chemotherapeutics has many side effects, researchers have focused on the potential use of medicinal plants as natural antitumor agents. Xanthium strumarium studied in this work as an herbal anticancer agent. This study aimed to evaluate the antitumor effect and metabolic alterations ca...

Despite a good initial response to chemotherapy, the majority of patients with epithelial ovarian cancer will eventually recur and die of their disease. The introduction of targeted therapies to traditional chemotherapy regimens has done little to improve overall survival in women with ovarian cancer. It has become increasingly apparent that the cancer epigenome contributes significantly to the...

Purpose: More effective, less toxic treatments for recurrent ovarian cancer are needed. Although more than 60% of ovarian cancers express the estrogen receptor (ER), ER-targeted drugs have been disappointing due to drug resistance. In other estrogen-sensitive cancers, estrogen activates Src to phosphorylate p27 promoting its degradation and increasing cell-cycle progression. Because Src is acti...

Unlike many other human solid tumors, ovarian tumors express many epithelial markers at a high level for cell growth and local invasion. The phosphoprotein Pinin plays a key role in epithelial cell identity. We showed that clinical ovarian tumors and ovarian cancer cell lines express a high level of Pinin when compared with normal ovarian tissues and immortalized normal ovarian surface epitheli...

Surgery plays a critical role in the optimal management of all stages of ovarian carcinoma. In apparent early-stage ovarian cancer, a comprehensive surgical evaluation allows stratification of patients into low- and high-risk categories. Low-risk patients may be candidates for fertility-sparing surgery and can safely avoid chemotherapy and be observed. Treatment of patients with high-risk early...

More than 95% of ovarian cancers originate from the epithelial cells on the surface of the ovary, which are termed ovarian surface epithelium (OSE). These OSE cells are modified peritoneal mesothelial cells separated from underlying ovarian surface stromal tissue by a basal lamina of dense collagenous connective tissue. Mesenchymal-epithelial cell interactions between stromal cells and OSE cell...

Epithelial ovarian cancer (EOC) is the leading cause of death for gynecological cancer. Most patients are not diagnosed until the cancer is at an advanced stage with poor prognosis. Notch1 signaling pathway plays an oncogenic role in EOC. There have been few studies on enzymatic activity of γ-secretase and the mechanism of how γ-secretase inhibitor works on cancer cell. Here, we show that Jagge...
