BACKGROUND: Menopausal estrogen-alone therapy is a risk factor for endometrial and ovarian cancers. When a progestin is included with the estrogen daily (continuous estrogen-progestin combined therapy), there is no increased risk of endomet…

OBJECTIVE: Endometriosis is a common gynecologic disorder often associated with severe pelvic pain and infertility with few known modifiable risk factors. We investigated whether in utero and early life exposures are associated with surgica…

PURPOSE OF REVIEW: The purpose of this review is to discuss the most up to date research on endometriosis and chronic disease risk, highlighting the role treatments for endometriosis may play in these associations. RECENT FINDINGS: Previou…

BACKGROUND: Epithelial ovarian, fallopian tube, and primary peritoneal cancers have shared developmental pathways. Few studies have prospectively examined heterogeneity in risk factor associations across these three anatomic sites. METHODS…

STUDY QUESTION: Is recreational and residential sun exposure associated with risk of endometriosis? SUMMARY ANSWER: Tanning bed use in early adulthood, sunscreen use and history of sunburns were associated with a greater risk of endometrio…

BACKGROUND: Adolescents with endometriosis are a particularly underserved population who struggle with chronic pain. Despite widespread use, there are no published trials examining the individual effects of vitamin D and omega-3 (n-3) fatty…

Repeated exposure to the acute proinflammatory environment that follows ovulation at the ovarian surface and distal fallopian tube over a woman's reproductive years may increase ovarian cancer risk. To address this, analyses included indivi…

As a follow-up to genome-wide association analysis of common variants associated with ovarian carcinoma (cancer), our study considers seven well-known ovarian cancer risk factors and their interactions with 28 genome-wide significant common…

BACKGROUND: Modifiable risk factors such as diet may be important in both the etiology and progression of endometriosis as well as the prevalence of pain symptoms and infertility associated with this condition. In adults, higher intake of d…

Uterine leiomyomata (UL) are the most common neoplasms of the female reproductive tract and primary cause for hysterectomy, leading to considerable morbidity and high economic burden. Here we conduct a GWAS meta-analysis in 35,474 cases and…

BACKGROUND: Only 2 case-control studies have examined the associations between consumption of meat products and endometriosis risk with inconsistent results. Consumption of animal products has the potential to influence endometriosis risk t…

We aimed to validate the prognostic association of p16 expression in ovarian high-grade serous carcinomas (HGSC) and to explore it in other ovarian carcinoma histotypes. p16 protein expression was assessed by clinical-grade immunohistochemi…

STUDY QUESTION: Is there an association between physical and sexual abuse occurring in childhood or adolescence and risk of laparoscopically-confirmed endometriosis? SUMMARY ANSWER: Early life sexual and physical abuse was associated with …

STUDY QUESTION: Is there an association between intake of fruits and vegetables and risk of laparoscopically confirmed endometriosis? SUMMARY ANSWER: Higher intake of fruits, particularly citrus fruits, is associated with a lower risk of e…

Uterine leiomyomata (UL), also known as uterine fibroids, are the most common neoplasms of the reproductive tract and the primary cause for hysterectomy, leading to considerable impact on women’s lives as well as high economic burden 1,2 . …

Background: One model of ovarian cancer development model divides tumors into two types. Type I tumors are characterized by KRAS and BRAF mutations, which can activate mitogen-activated protein kinase (MAPK). Type II tumors are characterize…

Much evidence suggests a role for inflammation in the pathogenesis of endometriosis. Although investigators in numerous case-control studies have found elevation of inflammatory markers in patients with endometriosis, results were not consi…

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…

Menstrual pain, a common gynecological condition, has been associated with increased risk of ovarian cancer in some, but not all studies. Furthermore, potential variations in the association between menstrual pain and ovarian cancer by hist…

OBJECTIVE: To investigate the association between endometriosis and systemic lupus erythematosus (SLE) in prospectively collected population-based data. METHODS: We conducted a case-control study using Swedish registers, identifying female…

OBJECTIVES: The aetiologies of endometriosis, systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are all characterised by immune dysfunction. SLE and RA occur more often in women, and reproductive and hormonal factors have bee…
