BACKGROUND: The role of ovulation in epithelial ovarian cancer (EOC) is supported by the consistent protective effects of parity and oral contraceptive use. Whether these factors protect through anovulation alone remains unclear. We explore…

Our objective was to test whether p53 expression status is associated with survival for women diagnosed with the most common ovarian carcinoma histotypes (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], and clear cell carci…

PURPOSE: In many diseases, it is possible to classify a heterogeneous group into subgroups relative to tumor biology, genetic variations, or clinical and pathological features. No such classification is available for endometriosis. In our r…

BACKGROUND: PTEN loss is a putative driver in histotypes of ovarian cancer (high-grade serous (HGSOC), endometrioid (ENOC), clear cell (CCOC), mucinous (MOC), low-grade serous (LGSOC)). We aimed to characterise PTEN expression as a biomarke…

Einleitung: Die Endometriose ist mit ihren vielseitigen Erscheinungsformen ein Chamäleon unter den Erkrankungen. Eine eindeutige Ätiologie ist bislang nicht bekannt und die Heterogenität der klinischen Symptomatik erschwert die frühzeitige …

Zielsetzung Endometriose ist eine heterogene Erkrankung mit unterschiedlichen Erscheinungsformen und Ausprägungsgrade. Eine Einteilung in Untergruppen ist bisher nicht bekannt. Ziel dieser Fall-Fall-Studie ist es, eine Population von Endome…

Zielsetzung: Endometriose ist eine heterogene Erkrankung mit unterschiedlichen Erscheinungsformen und Ausprägungsgraden. Bisher existiert jedoch keine etablierte Einteilung in Untergruppen. Ziel dieser Fall-Fall-Studie ist es, eine Populati…

It is known that endometriosis is associated with an increased risk for certain forms of ovarian cancer. However it is unknown, which kind of endometriosis is associated with ovarian cancer and furthermore, if endometriosis is associated wi…

Sowohl für das Ovarialkarzinom als auch für Endometriose sind genetische Varianten als Risikofaktoren validiert. Endometriose ist als Risikofaktor für das klarzellige, das endometrioide und das low grade seröse Ovarialkarzinom beschrieben. …

Epidemiological, biological, and molecular data suggest links between endometriosis and endometrial cancer, with recent epidemiological studies providing evidence for an association between a previous diagnosis of endometriosis and risk of …

Several genetic variants have been validated as risk factors for endometriosis, endometrial and ovarian cancer. Endometriosis has also been described as a risk factor for endometrial and ovarian cancer. The aim of the present study was to t…

Endometrial cancer is the most commonly diagnosed cancer of the female reproductive tract in developed countries. Through genome-wide association studies (GWAS), we have previously identified eight risk loci for endometrial cancer. Here, we…

OBJECTIVE: Several genetic variants have been validated as risk factors for ovarian cancer. Endometriosis has also been described as a risk factor for ovarian cancer. Identifying genetic risk factors that are common to the two diseases migh…

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptib…

BACKGROUND: Regulatory T (Treg) cells, a subset of CD4+ T lymphocytes, are mediators of immunosuppression in cancer, and, thus, variants in genes encoding Treg cell immune molecules could be associated with ovarian cancer. METHODS: In a po…

BACKGROUND: In vitro and observational epidemiological studies suggest that vitamin D may play a role in cancer prevention. However, the relationship between vitamin D and ovarian cancer is uncertain, with observational studies generating c…

OBJECTIVE: Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3' UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as wit…

Disruption in circadian gene expression, whether due to genetic variation or environmental factors (e.g., light at night, shiftwork), is associated with increased incidence of breast, prostate, gastrointestinal and hematologic cancers and g…

BACKGROUND: No screening programs are available for ovarian or endometrial cancer. One reason for this is the low incidence of the conditions, resulting in low positive predictive values for tests, which are not very specific. One way of ad…

There is no screening program for ovarian or endometrial cancer. One reason for that could be the relatively low incidence with subsequently low positive predictive values for tests with low specifity. One way to address the problem could b…

OBJECTIVE: To evaluate whether endometriosis-associated genetic variation affects risk of ovarian cancer. DESIGN: Pooled genetic analysis. SETTING: University hospital. PATIENT(S): Genetic data from 46,176 participants (15,361 ovarian ca…

Common variants in the hepatocyte nuclear factor 1 homeobox B (HNF1B) gene are associated with the risk of Type II diabetes and multiple cancers. Evidence to date indicates that cancer risk may be mediated via genetic or epigenetic effects …

Genome-wide association studies (GWAS) have identified 12 epithelial ovarian cancer (EOC) susceptibility alleles. The pattern of association at these loci is consistent in BRCA1 and BRCA2 mutation carriers who are at high risk of EOC. After…

BACKGROUND: Medical research studies are becoming increasingly important for optimizing the prevention, diagnosis and treatment of illnesses. Participation in research studies can have many benefits for patients. In randomized and controlle…

Epidemiological studies have demonstrated associations between endometriosis and certain histotypes of ovarian cancer, including clear cell, low-grade serous and endometrioid carcinomas. We aimed to determine whether the observed associatio…
