Context: Androgen excess in women is predominantly due to underlying polycystic ovary syndrome (PCOS). However there is a lack of clarity regarding patterns and severity of androgen excess that should be considered predictive of non-PCOS pathology. Objective: We examined the diagnostic utility of simultaneous measurement of serum dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4) and testosterone (T) to delineate biochemical signatures and cut-offs predictive of non-PCOS disorders in women with androgen excess...

PURPOSE: Fully sialylated alpha-chain of complement 4-binding protein (A2160) is a member of the glycoprotein family and has recently been identified as a diagnostic biomarker for epithelial ovarian cancer. This study examined the utility of A2160 as a prognostic biomarker for this disease. METHODS: This is a retrospective analysis of prospectively collected plasma samples from 93 women with stage I-IV epithelial ovarian cancer who underwent primary cytoreductive surgery between 2009 and 2014...

Chemotherapy is one of the main approach for ovarian cancer. Cancer stem cells (CSCs) escape chemotherapy and lead to chemoresistance. We previously demonstrated that cordycepin (Cd) inhibited metastasis in human ovarian carcinoma cells, the aim of this study is to investigate the effects of Cd on ovarian cancer stemness. TGF-beta was used to induce chemoresistance of chemotherapeutic agent cisplatin in SKOV-3 ovarian cancer cells. After treating with 100 μM of Cd, cell viability, the percentage of cancer stem cells, and the levels of matrix metalloproteinases (MMPs) were decreased in TGF-beta-induced SKOV-3 cells...

Bivalent chromatin domains containing both active H3K4me3 and repressive H3K27me3 histone marks define gene sets poised for expression or silencing in differentiating embryonic stem (ES) cells. In cancer cells aberrantly poised genes may facilitate changes in transcriptional states after exposure to anti-cancer drugs. In this study, we used ChIP-seq to characterize genome-wide positioning of H3K4me3 and H3K27me3-associated chromatin in primary high-grade serous ovarian carcinomas and in normal ovarian surface and fallopian tube tissue...

The initial molecular events that lead to malignant transformation of the fimbria of the fallopian tube (FT) through high-grade serous ovarian carcinoma (HGSC) remain poorly understood. In this study, we report that increased expression of signal transducer and activator of transcription 3 (pSTAT3 Tyr705) and suppression or loss of protein inhibitor of activated STAT3 (PIAS3) in FT likely drive HGSC. We evaluated human tissues-benign normal FT, tubal peritoneal junction (TPJ), p53 signature fallopian tube tissue, tubal intraepithelial lesion in transition (TILT), serous tubal intraepithelial carcinoma (STIC) without ovarian cancer, and HGSC for expression of STAT3/PIAS3 (compared with their known TP53 signature) and their target proliferation genes...

The distinction of primary mucinous ovarian carcinoma (PMOC) from other primaries or secondaries is essential for selecting therapeutic options and prognostication. We aimed to characterize the immunohistochemical profile of 36 PMOCs using an extended immunohistochemical panel, with clinicopathologic features and outcome. PAX8 was negative in 30 (83.3%), and SATB2 was negative in 32/35. HNF1B, AMACR, and napsin-A were detected in 33 (91.7%), 35 (97.2%), and 0 (0%), respectively. MMR proteins and ARID1A were retained in 100%; PTEN was lost in 4 (11...

Ovarian fibromas are the most common benign solid ovarian tumors, which are often difficult to diagnose preoperatively. Ovarian fibromas, especially in bilateral cases, may be cases of Gorlin-Goltz syndrome (GGS), a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. This case report describes a 25 year-old female with GGS, bilateral ovarian fibroma, endometriosis and septated uterus, which was referred to the Gynecology Clinic of Rasoul-e-Akram Hospital in October 2016...

BACKGROUND: Secreted frizzled-related protein 4 (SFRP4) is a glycoprotein that act as a competitor of both canonical and non-canonical Wnt pathways. SFRP4 is mostly expressed in ovary and played a significant role as a target molecule to cure ovarian carcinoma. OBJECTIVE: Multiple chemical agonists are being used to cure ovary melanoma. We are interested to theoretically analyze the compounds through computational approaches for their inhibitory effects against SFRP4...

Ovarian cancer often presents at an advanced stage with widespread peritoneal and/or extra-abdominal metastases. Complete cytoreduction is the mainstay of treatment for disease confined to peritoneum. But in patients with distant metastases, the role and rationale is less obvious. One of the the most common sites of extra-abdominal disease is the cardiophrenic lymph node (CPLN). In this paper, we described the management of a patient with International Federation of Gynecology and Obstetrics (FIGO) stage IVB epithelial ovarian carcinoma and widespread peritoneal and extra-abdominal metastases to the CPLN, who underwent complete cytoreduction including excision of enlarged CPLN, following neoadjuvant chemotherapy...

Corilagin, a gallotannin, is one of the major active components of many ethnopharmacological plants. It was isolated from Caesalpinia coriaria (Jacq.) Willd. (dividivi) by Schmidt in 1951 for the first time. In the past few decades, corilagin was reported to exhibit anti-tumor, anti-inflammatory and hepatoprotective activities, etc. However, little attention was paid to its pharmacological properties due to the complicated and inefficient extract method. In recent years, with the development of extraction technology corilagin was much easier to obtain than before...

BACKGROUND: Serous borderline tumor (SBT) of the micropapillary type (SBT-MP) became one of the major pathological SBT diagnoses in addition to typical SBT, and was also defined as "non-invasive" low-gradeserous carcinoma according to the World Health Organization (WHO) classification in 2014. In this study, we investigated the MRI appearance of SBT-MP compared to that of typical SBT in order to identify specific imaging features of SBT-MP that correspond to pathological findings. METHODS: MR images of 6 histologically proven ovarian SBT-MP in four patients and 14 typical SBT in ten patients were reviewed retrospectively...

Endometriosis is a risk factor for type I epithelial ovarian cancer but an issue to be clarified is the site of origin of endometriosis associated ovarian cancer. Here we proposed that the uterus may be the organ of origin of ovarian endometrioid cancer associated with endometriosis. Thus, the first neoplastic transformation would characterize the uterine cells migrating in the pelvis via retrograde menstruation and they would implant secondarily on the ovary. Supporting this hypothesis, an higher incidence of synchronous precancerous and cancerous endometrial pathology in patients affected by ovarian endometrioid cancer associated with endometriosis was showed...

BACKGROUND: Risk-reducing salpingo-oophorectomy (RRSO) is recommended for BRCA1/2 mutation carriers because of their increased risk of ovarian carcinoma. Despite RRSO, metachronous peritoneal carcinomatosis occasionally is diagnosed. METHODS: The literature was searched for BRCA1/2 mutation carriers with peritoneal carcinomatosis after risk-reducing surgery. The authors were asked for additional data. Clinical and histopathological data were descriptively analyzed...

OBJECTIVE: Two distinct types of endometrial carcinoma (EC) with different etiology, tumor characteristics, and prognosis are recognized. We investigated if the prognostic impact of comorbidity varies between these 2 types of EC. Furthermore, we studied if the recently developed ovarian cancer comorbidity index (OCCI) is useful for prediction of survival in EC. MATERIALS AND METHODS: This nationwide register-based cohort study was based on data from 6487 EC patients diagnosed in Denmark between 2005 and 2015...
