In September 2016, the 11th biennial ovarian cancer research symposium was presented by the Rivkin Center for Ovarian Cancer and the American Association for Cancer Research. The 2016 symposium focused on 4 broad areas of research: Mechanisms of Initiation and Progression of Ovarian Cancer, Tumor Microenvironment and Models of Ovarian Cancer, Detection and Prevention of Ovarian Cancer, and Novel Therapeutics for Ovarian Cancer. The presentations and abstracts from each of these areas are reviewed in this su...
Ovarian cancer is the most lethal gynaecologic cancer. Disease prevention may be the only method to reduce the incidence of ovarian cancer. The Society of Gynecologic Oncology advised that salpingectomies may be an appropriate and feasible strategy for ovarian cancer risk reduction. This study conducted an economic evaluation from a societal perspective of bilateral salpingectomies versus conventional sterilization techniques in the prevention of ovarian cancer.
Ovarian cancer is frequently diagnosed at an advanced stage and 70% of patients experience recurrence months to years from initial diagnosis. The expression of paraneoplastic antigens can result in the occurrence of onconeural autoantibodies in ovarian cancer that may be associated with neurological disorders that are clinically manifested in patients before diagnosis of ovarian cancer. These paraneoplastic antigens can serve as excellent biomarkers not only for early detection but also for monitoring ovari...
Ovarian cancer remains to be the most lethal of all gynecologic malignancies. There is no effective screening test proven to reduce the mortality associated with this disease. Costs of treating ovarian cancer are substantial and among the highest of all cancer types. Therefore, it is essential to pursue strategies to prevent ovarian cancer that are cost-effective in the context of our health care system. There are 2 subgroups of women for whom ovarian cancer prevention strategies have been evaluated for eff...
Ovarian cancer is one of the leading gynecologic malignancies globally, the 5-year survival rate for patients with advanced stage ovarian cancer is very low. Our objective was to test the hypothesis that miR-335 was associated with the survival of patients with ovarian cancer.
The aim of this study was to review the latest research advances on the topics of the ovarian cancer tumor microenvironment and models of ovarian cancer.
Metastasis accounts for the most lethal reason for the death of ovarian cancer patients, but remains largely untreated. Epithelial-mesenchymal transition (EMT) is critical for the conversion of early-stage ovarian tumours into metastatic malignancies. Thus the exploration of the signalling pathways promoting EMT would open potential opportunities for the treatment of metastatic ovarian cancer. Herein, the putative role of MDM2 in regulating EMT and metastasis of ovarian cancer SKOV3 cells was investigated.
A large variety of mouse models for cancer exist, also in the field of ovarian cancer. Each model possesses different features, which makes it difficult to interpret their translational value. This review provides an overview of the available ovarian cancer mouse models and their possible use in search for new treatments.
Findings from in vitro studies suggest that increased exposure to thyroid hormones can influence progression of ovarian tumours. However, epidemiologic evidence on this topic is limited.
There have been no major improvements in the overall survival of ovarian cancer patients in recent decades. Even though more accurate surgery and more effective treatments are available, the mortality rate remains high. Given the differences in origin and the heterogeneity of these tumors, research to elucidate the signaling pathways involved is required. The Transforming Growth Factor (TGFβ) family controls different cellular responses in development and cell homeostasis. Disruption of TGFβ signaling has...
S100A1 is a calcium-binding protein belonging to the family of S100 proteins, and is highly expressed in ovarian cancer. However, its role in ovarian cancer has not yet been fully elucidated. In this study, we examined S100A1 expression in ovarian cancer tissues and normal tissue controls and analyzed the correlation between S100A1 expression and clinicopathological parameters. We found that S100A1 expression was significantly upregulated in ovarian cancer tissues compared with fallopian and normal ovarian ...
Ovarian cancer is one of most common malignancies in women and is associated with high reoccurrence rate and poor prognosis. This study is designed to investigate the anti-tumor effects of amentoflavone (AF), one of the major active ingredients of S. tamariscina, against ovarian cancer.
Freezing strips of ovarian cortex before chemotherapy followed by transplantation is an experimental method to preserve fertility for reproductive-aged women with cancer. We report a case of a cancer patient who developed a mucinous cystadenoma in a grafted piece of ovarian cortex.
Abdominal obesity is linked with a higher risk of developing ovarian cancer. However, the link between abdominal obesity and survival after diagnosis of ovarian cancer is unknown. The purpose of this study was to determine the impact of abdominal obesity on progression-free survival in patients with ovarian cancer.
Identification of families at risk for ovarian cancer offers the opportunity to consider prophylactic surgery thus reducing ovarian cancer mortality. So far, identification of potentially affected families in Germany was solely performed via family history and numbers of affected family members with breast or ovarian cancer. However, neither the prevalence of deleterious variants in BRCA1/2 in ovarian cancer in Germany nor the reliability of family history as trigger for genetic counselling has ever been ev...
Ovarian cancer incidence differs substantially by race/ethnicity, but the reasons for this are not well understood. Data were pooled from the African American Cancer Epidemiology Study (AACES) and 11 case-control studies in the Ovarian Cancer Association Consortium (OCAC) to examine racial/ethnic differences in epidemiological characteristics with suspected involvement in epithelial ovarian cancer (EOC) aetiology.
Preclinical models are relatively underutilized and underfunded resources for modeling the pathogenesis and prevention of ovarian cancers. Several reviews have detailed the numerous published models of ovarian cancer. In this review, we will provide an overview of experimental model systems, their strengths and limitations, and use selected models to illustrate how they can be used to address specific issues about ovarian cancer pathogenesis. We will then highlight some of the preclinical prevention studies...
The potential predictive value of genetic polymorphisms in ovarian cancer first-line treatment is inconsistently reported. We aimed to review ovarian cancer pharmacogenetic studies to update and summarize the available data and to provide directions for further research.
Objective: To analyze patients' tendency towards genetics counseling and tests based on a prospective cohort study on hereditary ovarian cancer. Methods: From February 2017 to June 2017, among 220 cases of epithelial ovarian cancer in Peking Union Medical College Hospital, we collected epidemiological, pathological and tendency towards genetics counseling and tests via medical records and questionnaire.All patients would get education about hereditary ovarian cancer by pamphlets and WeChat.If they would rec...
In this study, we aimed to examine the expression of SLC4A11 in ovarian cancer and in normal ovarian tissues, its prognostic value and the possible mechanism of its dysregulation. Bioinformatic analysis was performed by using data from the GEO datasets, the Cancer Genome Atlas-Ovarian Cancer (TCGA-OV) and the Human Protein Atlas (HPA). Results showed that SLC4A11 was upregulated in ovarian cancer compared with normal ovarian epithelial tissues. In patients with primary serous ovarian cancer in TCGA-OV, the ...
To examine the cumulative incidence of subsequent ovarian cancer among young women with stage I endometrioid endometrial cancer who had ovarian conservation at surgical treatment.
A mortality benefit from screening for ovarian cancer has never been demonstrated. The aim of this study was to evaluate the screening outcomes for different histologic subtypes of ovarian cancers.
Long non-coding RNA SNHG20 has been demonstrated as playing crucial regulatory roles in a many types of cancer. However, the biological function of lncRNA SNHG20 in ovarian cancer are still unclear. In this study, we found that lncRNA SNHG20 was significantly increased in ovarian cancer. In addition, lncRNA SNHG20 knockdown suppressed the ovarian cancer progression, whereas overexpression of SNHG20 showed the opposite effects. Moreover, our results also revealed that lncRNA SNHG20 knockdown inhibited Wnt/β...
A host of studies have revealed that long non-coding RNAs (lncRNAs) are critically involved in the development and progression of epithelial ovarian cancer. LncRNA TUBA4B is recently identified to be a critical mediator in non-small cell lung cancer. However, the clinical roles and biological functions of lncRNA TUBA4B in epithelial ovarian cancer have yet to be fully clarified. The present study was conducted to explore the expression of lncRNA TUBA4B in human epithelial ovarian cancer tissues and potentia...
Ovarian clear cell carcinoma (OCCC) and high grade serous ovarian cancer (HGSOC) are associated with the highest risk of VTE among patients with epithelial ovarian cancer (EOC). Tissue factor (TF) is a transmembrane glycoprotein which can trigger thrombosis. We sought to evaluate if there is an association between VTE and tumor expression of tissue factor (TF), plasma TF, and microvesicle TF (MV TF) activity in this high-risk population.
