BACKGROUND: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, widespread environmental contaminants, and some are endocrine disrupting. Studies of gynecologic cancers are limited; we evaluated ovarian cancer, a rare, ofte…

BACKGROUND: Colorectal cancer (CRC) affects a growing number of females. Our objective was to evaluate the impact of CRC on sexual health outcomes among females, while controlling for age. METHODS: We conducted a cohort study using adminis…

BACKGROUND: Women with a family history of breast and/or ovarian cancer have an increased ovarian cancer risk. Yet it remains uncertain if common ovarian cancer risk factors-especially those that are modifiable-affect this high-risk populat…

OBJECTIVE: Proteomics may discover pathophysiological changes related to hepatocellular carcinoma, an aggressive and lethal type of cancer with low sensitivity for early stage diagnosis. DESIGN: We measured 1305 prediagnostic (median = 12.…

Generally, risk stratification models for cancer use effect estimates from risk/protective factor analyses that have not assessed potential interactions between these exposures. We have developed a 4-criterion framework for assessing intera…

BACKGROUND: Gynecologic surgery is hypothesized to reduce risk of breast cancer; however, associations may be modified by subsequent hormone use. Our objective was to examine the association between gynecologic surgery and breast cancer inc…

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…

BACKGROUND: Epidemiological studies have found that menopausal hormone therapy (MHT) use is associated with an increased ovarian cancer risk. However, whether different MHT types confer the same level of risk is unclear. We estimated the as…

BACKGROUND: Known risk alleles for epithelial ovarian cancer (EOC) account for approximately 40% of the heritability for EOC. Copy number variants (CNVs) have not been investigated as EOC risk alleles in a large population cohort. METHODS:…

BACKGROUND: Parity is associated with decreased risk of invasive ovarian cancer; however, the relationship between incomplete pregnancies and invasive ovarian cancer risk is unclear. This relationship was examined using 15 case-control stud…

BACKGROUND: Long-term effects of assisted reproductive technology (ART) on ovarian tumor risk are unknown. METHODS: This nationwide cohort study comprises 30 625 women who received ovarian stimulation for ART in 1983-2000 and 9988 subferti…

BACKGROUND: The causes of racial disparities in epithelial ovarian cancer (EOC) incidence remain unclear. Differences in the prevalence of ovarian cancer risk factors may explain disparities in EOC incidence among African American (AA) and …

BACKGROUND: Experimental evidence supports a role of lipid dysregulation in ovarian cancer progression. We estimated associations with ovarian cancer risk for circulating levels of four lipid groups, previously hypothesized to be associated…

BACKGROUND: Aspirin use is associated with reduced risk of several cancers. A pooled analysis of 12 case-control studies showed a 10% decrease in ovarian cancer risk with regular aspirin use, which was stronger for daily and low-dose users.…

BACKGROUND: Pelvic inflammatory disease (PID) has been associated with ovarian cancer risk. To clarify the role of Chlamydia trachomatis and other infectious agents in the development of ovarian cancer, we evaluated the association of serol…

BACKGROUND: Recent studies have called into question the long-held belief that hysterectomy without oophorectomy protects against ovarian cancer. This population-based longitudinal record-linkage study aimed to explore this relationship, ov…

With recent ovarian cancer screening studies showing no clinically significant mortality benefit, preventing this disease, identifying high-risk populations, and extending survival remain priorities. However, several challenges are impeding…

BACKGROUND: While progestin addition to estrogen mitigates endometrial cancer risk, the magnitude of the effect on incidence, specific endometrial cancer histologies, and endometrial cancer mortality remains unsettled. These issues were ass…

Metastases are tumors that develop at a distance from their primary origin and are responsible for the death of 90% of cancer patients. For over a century the notion of seed (migrating cells) and soil (the locus where those cells anchor) pr…

BACKGROUND: Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy, responsible for 13 000 deaths per year in the United States. Risk prediction based on identifying germline mutations in ovarian cancer susceptibility g…

BACKGROUND: The evidence for an association between migraine and breast cancer risk is inconclusive. While female sex hormones have been proposed as one underlying mechanism, data on sex hormone levels in migraineurs are sparse. METHODS: W…

BACKGROUND: Accumulating evidence suggests that many ovarian cancers represent metastases from occult fallopian tube carcinomas or tumors arising within ovarian endometriosis. We hypothesized that small ovarian volumes, as reflected in nonv…

BACKGROUND: Regular aspirin use is associated with reduced risk of several malignancies. Epidemiologic studies analyzing aspirin, nonaspirin nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen use and ovarian cancer risk have bee…

The Ovarian Task Force of the Gynecologic Cancer Steering Committee convened a clinical trials planning meeting on October 28-29, 2011, with the goals to identify key tumor types, associated molecular pathways, and biomarkers for targeted d…
