Epidemiologic studies have suggested that diabetes mellitus (DM) might be associated with risk of ovarian cancer; however, the results have been inconsistent. The aim of this study was to determine the relationship between DM and the incidence of ovarian cancer on the basis of cohort studies.Relevant studies from PubMed, Embase, and the Cochrane Library until September 2016 were collected. The summary risk ratio (RR) was used as the effect measure in a random effects model. Sensitivity analysis, subgroup analysis, and calculation of publication bias were conducted...

Laparoscopic entry techniques vary amongst surgeons and gynaecologists, with gynaecologists favouring Veress needle entry. Recent RCOG/BSGE recommendations have recommended retrieval of ovarian masses via the umbilical port with resultant less postoperative pain and a faster retrieval time than with retrieval through lateral ports of the same size. This is a prospective observational study reviewing the Hasson entry technique and the introduction of retrieval of specimens via the umbilicus in patients scheduled for a laparoscopy procedure at our day surgery unit...

Gastric metastasis from ovarian cancer is exceptionally rare and generally occurs in advanced stages. A 71-year-old woman presented with a solitary gastric submucosal mass 8 years after the diagnosis of a stage IA ovarian serous adenocarcinoma. Endoscopy showed a tumor covered with normal gastric mucosa. Initially, a gastrointestinal stromal tumor was suspected, but biopsy revealed a histology of invasive micropapillary carcinoma, similar to the histological findings of the previously resected ovarian tumor...

OBJECTIVE: We report a rare case of vaginal cuff dehiscence with small bowel evisceration at 7 months post robotic-staging surgery. CASE REPORT: A 41-year-old woman was sent to the emergency room with sudden onset of abdominal pain, vaginal bleeding, and vaginal protruding mass after sexual activity. She had a history of synchronous uterine and ovarian cancer treated with robotic-staging surgery 7 months before. Then she received six courses of postoperative adjuvant chemotherapy, and the last chemotherapy ended 1 month ago...

OBJECTIVE: Ovarian juvenile granulosa cell tumor has an interesting association with multiple enchondromatosis (Ollier disease and Maffucci syndrome) and should be considered a leading diagnosis when an ovarian mass is found in young patients with these conditions. Besides the association with nonskeletal malignancies, there is a high risk of malignant transformation of enchondroma in chondrosarcoma as was also the case in this instance. CASE REPORT: The report uses multiple images to document the representative and characteristic markers of multiple enchondromas in a 22-year-old patient with Ollier disease complicated by malignant transformation of chondrosarcoma and in whom the disease is associated with ovarian juvenile granulosa cell tumor of the right ovary...

Melittin, the main peptide present in bee venom, has been proposed as having potential for anticancer therapy; the addition of melittin to cisplatin, a first line treatment for ovarian cancer, may increase the therapeutic response in cancer treatment via synergy, resulting in improved tolerability, reduced relapse, and decreased drug resistance. Thus, this study was designed to compare the metabolomic effects of melittin in combination with cisplatin in cisplatin-sensitive (A2780) and resistant (A2780CR) ovarian cancer cells...

Reimplantation of cryopreserved ovarian tissue (OT) can successfully restore ovarian function in young cancer patients after gonadotoxic treatment. However, for patients with leukaemia, there is a risk of malignant cell transmission. Our objective was to evaluate minimal disseminated disease in OT from leukaemia patients and test a follicle isolation technique to obtain disease-free follicle suspensions. Cryopreserved OT from 12 leukaemia patients was thawed and analysed by histology and long-term xenografting in immunosuppressed mice...

BACKGROUND: Several conflicting studies with results on the biological variability of serum anti-Müllerian hormone (AMH) levels have been reported. Most of the studies have not focused on whether the level of AMH fluctuations shows variability by a baseline ovarian follicular reserve. AIM: To reveal whether intracyclic variation in AMH levels occurs among women with adequate, high and diminished ovarian reserve patterns. STUDY DESIGN: In this prospective cross-sectional study, 171 infertile women between the ages of 18 and 42 years were recruited...

BACKGROUND: Ovarian cancer is one of the highest mortality cancers in gynaecology. Discrimination of benign masses from malignant ones may sometimes become a challenge for the clinician since there is not a reliable tumour marker, thus some unnecessary, highly morbid operations can be performed. AIMS: To explore the efficacy of human epididymis 4 (HE 4) and cancer antigen 125 (CA 125) markers in differentiating malignant and benign pelvic masses of ovarian origin and to identify the cut-off points for those markers...

Ovarian high-grade serous carcinoma (HGSC) results in the highest mortality among gynecological cancers, developing rapidly and aggressively. Dissimilarly, serous borderline ovarian tumors (BOT) can progress into low-grade serous carcinomas and have relatively indolent clinical behavior. The underlying biological differences between HGSC and BOT call for accurate diagnostic methodologies and tailored treatment options, and identification of molecular markers of aggressiveness could provide valuable biochemical insights and improve disease management...

Dietary polyunsaturated fatty acids (PUFAs) are critical to the success of ovarian development in marine crustaceans, especially for domesticated species such as the black tiger shrimp Penaeus monodon. These fatty acids are stored in a midgut gland called the hepatopancreas and subsequently serve as an energy source or are incorporated in yolk during ovarian development. PUFAs are known precursors of hydroxy fatty acids, including hydroxyeicosatetraenoic acid and hydroxyeicosapentaenoic acid (HEPE), which are catalyzed by lipoxygenases (LOX)...

BACKGROUND: Ovarian tumours are a leading cause of death in Ghana. Even though geographical and racial differences exist in the frequency, types and age distribution of primary ovarian tumours, information about the clinical and pathological characteristics of ovarian tumours in Ghana and its neighboring countries is scanty. We determined the frequency, age distribution, histopathological types and clinical features of primary ovarian tumours diagnosed at the Korle-Bu Teaching Hospital in Ghana to aid in the management of patients...

We investigated the effects of angiotensin-converting enzyme (ACE) inhibition and aerobic physical training on the heart of old female rats (82-wk-old) submitted to premature ovarian failure (10-wk.-old). We used different approaches: morphology and function by echocardiography, reactivity of the coronary bed and left ventricular contractibility (Langendorff Technique). Female Wistar ovariectomized (OVX) rats (n=42) were assigned to one of four groups: OVX, vehicle treated only; OVX-EM, Enalapril Maleate only (EM, 10mg·kg(-1)·d(-1)); OVX-T, aerobic trained only; and OVX-EMT, treated with Enalapril Maleate and aerobic trained...

Ovarian superstimulation with exogenous gonadotropins has been extensively used to produce in vivo-derived embryos for embryo transfer in cattle. This process modifies the antral follicle microenvironment and affects oocyte and embryo quality as well the differentiation of granulosa cells. Lipids play significant roles in the cell, such as energy storage, cell structure, and fine-tuning of the physical properties and functions of biological membranes. The phospholipid (PL) contents as well as the effects of superstimulatory treatments on the PL profile of follicular fluid from cows, however, remain unknown...

Oct4A is a master regulator of self-renewal and pluripotency in embryonic stem cells. It is a well-established marker for cancer stem cell (CSC) in malignancies. Recently, using a loss of function studies, we have demonstrated key roles for Oct4A in tumor cell survival, metastasis and chemoresistance in in vitro and in vivo models of ovarian cancer. In an effort to understand the regulatory role of Oct4A in tumor biology, we employed the use of an ovarian cancer shRNA Oct4A knockdown cell line (HEY Oct4A KD) and a global mass spectrometry (MS)-based proteomic analysis to investigate novel biological targets of Oct4A in HEY samples (cell lysates, secretomes and mouse tumor xenografts)...

BACKGROUND: The advent of effective chemotherapeutic agents for ovarian carcinoma has made radical abdomino-pelvic radiation redundant. Nevertheless, palliative pelvic radiotherapy still has a role in palliating local symptoms. However, its effect on progression-free survival (PFS) may be debated. AIMS: To study the outcome of fractionated palliative pelvic radiotherapy in relapsed ovarian cancers in terms of symptom control and PFS. METHODS: Twenty-three patients of ovarian cancers, heavily pretreated with chemotherapy and with recurrent or residual pelvic masses, were planned for palliative pelvic radiotherapy to the dose of 46-50 Gy in 23-25 fractions in 4...

Elevated levels of human chitinase-like proteins (CLPs) are associated with numerous chronic inflammatory diseases and several cancers, often correlating with poor prognosis. Nevertheless, there is scant knowledge of their function. The CLPs normally mediate immune responses and wound healing, and when upregulated, they can promote disease progression by remodeling tissue, activating signaling cascades, stimulating proliferation and migration, and by regulating adhesion. We identified Imaginal disc growth factors (Idgfs), orthologs of human CLPs CHI3L1, CHI3L2, and OVGP1, in a proteomics analysis designed to discover factors that regulate tube morphogenesis in a Drosophila melanogaster model of tube formation...
