A missense single-nucleotide polymorphism (SNP) in the immune modulatory gene IL1A has been associated with ovarian cancer risk (rs17561). Although the exact mechanism through which this SNP alters risk of ovarian cancer is not clearly unde…

Background and objectivesThe goal of this study is to obtain updated surveillance statistics for hysterectomy procedures in the United States and identify factors associated with undergoing a minimally invasive approach to hysterectomy.Meth…

Survival in epithelial ovarian cancer (EOC) is influenced by the host immune response, yet the key genetic determinants of inflammation and immunity that affect prognosis are not known. The nuclear factor-κB (NF-κB) transcription factor fam…

OBJECTIVE: To harmonize standard operating procedures (SOPs) and standardize the recording of associated data for collection, processing, and storage of human tissues relevant to endometriosis. DESIGN: An international collaboration involvi…

OBJECTIVE: To harmonize the collection of nonsurgical clinical and epidemiologic data relevant to endometriosis research, allowing large-scale collaboration. DESIGN: An international collaboration involving 34 clinical/academic centers and …

OBJECTIVE: To harmonize standard operating procedures (SOPs) and standardize the recording of associated data for collection, processing, and storage of fluid biospecimens relevant to endometriosis. DESIGN: An international collaboration in…

STUDY QUESTION: Is there a relationship between body mass index (BMI), body shape and endometriosis? SUMMARY ANSWER: Endometriosis is inversely associated with early adult BMI and may correlate with a peripheral body fat distribution. WHAT …

PurposeThe majority of previous studies have observed an increased risk of mucinous ovarian tumors associated with cigarette smoking, but the association with other histological types is unclear. In a large pooled analysis, we examined the …

HNF1B is overexpressed in clear cell epithelial ovarian cancer, and we observed epigenetic silencing in serous epithelial ovarian cancer, leading us to hypothesize that variation in this gene differentially associates with epithelial ovaria…

Whilst previous studies have reported that higher BMI increases a woman's risk of developing ovarian cancer, associations for the different histological subtypes have not been well defined. As the prevalence of obesity has increased dramati…

PurposeTest the hypothesis that puerperal mastitis may alter immunity related to the mucin (MUC) family of glycoproteins and lower risk of ovarian cancer.MethodsIn two case-control studies conducted in New England between 1998 and 2008, we …

BackgroundStudies evaluating the association between alcohol intake and ovarian carcinoma (OC) are inconsistent. Because OC and ovarian borderline tumor histologic types differ genetically, molecularly and clinically, large numbers are need…

STUDY QUESTION: Do reproductive risk factor associations differ across subgroups of invasive epithelial ovarian cancer (EOC) defined by the dualistic model (type I/II) or a histologic pathway-based classification? SUMMARY ANSWER: Associati…

Previous studies have observed that tubal ligation and hysterectomy are associated with a decreased risk of ovarian cancer; however, little is known about whether these associations vary by surgical characteristics, individual characteristi…

BACKGROUND: Endometriosis is a risk factor for epithelial ovarian cancer; however, whether this risk extends to all invasive histological subtypes or borderline tumours is not clear. We undertook an international collaborative study to asse…

Prolactin (PRL) and thyroid stimulating hormone (TSH) serve important roles in the reproductive and other systems. Active smoking is associated with changes in PRL and TSH secretion, but the relationship between secondhand tobacco smoke (ST…

BackgroundTelomeres protect chromosomal ends, shorten with cellular division, and signal cellular senescence, but unchecked telomere attrition can lead to telomere dysfunction, upregulation of telomerase, and carcinogenesis. Shorter telomer…

OBJECTIVE: To develop a risk-factor score that may provide additional guidance to women and their physicians regarding elective bilateral salpingo-oophorectomy at the time of hysterectomy. METHODS: From a case-control study conducted from 1…

OBJECTIVE: To investigate the association between self-reported endometriosis and the putative functional promoter +331C/T single nucleotide polymorphism and the PROGINS allele. DESIGN: Control subjects from ovarian cancer case-control stu…

ObjectiveThe purpose of this prospective study was to study the association between rotating nightshift work and endometriosis risk within the Nurses' Health Study II.Study designWe found 89,400 women without diagnosed endometriosis at base…

BackgroundInfertility and early pregnancy loss are prevalent as is exposure to secondhand tobacco smoke (STS). Previous research has suggested a relationship between STS exposure and early pregnancy loss, but studies have been limited by sm…

BACKGROUND: An inverse association between adult body mass index (BMI) and risk of endometriosis has frequently been reported. However, the association between body size during childhood and early adulthood and endometriosis is not as well …

ObjectiveCA125 at presentation of ovarian cancer carries important prognostic significance; but, other than tumor characteristics, little is known about factors that influence CA125 levels. We examined the effect of epidemiologic variables …

BACKGROUND: In the one study examining the relationship, adolescent physical activity was not associated with risk for endometriosis. Case-control studies have shown 40-80% reductions in risk for adult activity, while only an 11% reduction …

BACKGROUND: Regular exercise has been associated with a 40%-80% reduction in risk for endometriosis in several case-control studies. However, women experiencing symptoms prior to their diagnosis may be less likely to exercise than healthy c…
