Associations of tubal ligation and hysterectomy with serum androgen and estrogen metabolites among postmenopausal women in the Women's Health Initiative Observational Study.
Cancer causes & control : CCC ·doi:10.1007/s10552-024-01882-4

PurposeHysterectomy is associated with subsequent changes in circulating hormone levels, but the evidence of an association for tubal ligation is unclear. We evaluated whether circulating concentrations of androgens and estrogens differ by …

Circulating estrogens and postmenopausal ovarian and endometrial cancer risk among current hormone users in the Women's Health Initiative Observational Study.
Cancer causes & control : CCC ·doi:10.1007/s10552-019-01233-8

PurposeMenopausal hormone therapy (MHT) use induces alterations in circulating estrogens/estrogen metabolites, which may contribute to the altered risk of reproductive tract cancers among current users. Thus, the current study assessed asso…

Modification of the Associations Between Duration of Oral Contraceptive Use and Ovarian, Endometrial, Breast, and Colorectal Cancers.
JAMA oncology ·doi:10.1001/jamaoncol.2017.4942

ImportanceAlthough oral contraceptive (OC) use is common, the influence of OC use on carcinogenesis is not fully understood. A recent Agency for Healthcare Research and Quality report identified a need to understand the consistency of OC us…

Analysis of serial ovarian volume measurements and incidence of ovarian cancer: implications for pathogenesis
Journal of the National Cancer Institute ·doi:10.1093/jnci/dju262

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…

Pre-diagnostic serum levels of inflammation markers and risk of ovarian cancer in the prostate, lung, colorectal and ovarian cancer (PLCO) screening trial
Gynecologic oncology ·doi:10.1016/j.ygyno.2014.08.025

OBJECTIVE: Pro-inflammatory mechanisms may explain the increased ovarian cancer risk linked to more lifetime ovulations, endometriosis, and exposure to talc and asbestos, as well as decreased risk with non-steroidal anti-inflammatory drugs.…

2013
Hormonal risk factors and invasive epithelial ovarian cancer risk by parity.
British journal of cancer ·doi:10.1038/bjc.2013.344

BackgroundRecent studies have suggested that several ovarian cancer risk factors differ by parity status, but these findings have not been confirmed. We evaluated whether known risk factors of ovarian cancer differ between nulliparous and p…

Risk prediction for breast, endometrial, and ovarian cancer in white women aged 50 y or older: derivation and validation from population-based cohort studies.
PLoS medicine ·doi:10.1371/journal.pmed.1001492

BackgroundBreast, endometrial, and ovarian cancers share some hormonal and epidemiologic risk factors. While several models predict absolute risk of breast cancer, there are few models for ovarian cancer in the general population, and none …
