Borderline ovarian tumors primarily affect younger women and are associated with favorable prognosis, making fertility-sparing surgery a viable option. However, owing to recurrence and malignant transformation risks, careful monitoring is r…

IN BRIEF: By tissue-selective next-generation sequencing, we showed that adenomyotic epithelium harbored genomic alterations thought to be relevant to the development and progression of adenomyosis, including somatic mutations in several ca…

Endometriosis is known to be associated with an increased risk of endometrioid and clear cell ovarian cancer. However, the association between endometriosis and endometrial cancer is controversial. Therefore, we retrospectively analyzed the…

Endometriosis is a common condition associated with debilitating pelvic pain and infertility. A genome-wide association study meta-analysis, including 60,674 cases and 701,926 controls of European and East Asian descent, identified 42 genom…

STUDY QUESTION: Is there a shared genetic or causal association of endometriosis with asthma or what biological mechanisms may underlie their potential relationships? SUMMARY ANSWER: Our results confirm a significant but non-causal associat…

Evidence from observational studies indicates that endometriosis and depression often co-occur. However, conflicting evidence exists, and the etiology as well as biological mechanisms underlying their comorbidity remain unknown. Utilizing g…

STUDY QUESTION: Are there common mutation profiles between epithelial and stromal cells in ovarian endometriotic tissue and the normal endometrium? SUMMARY ANSWER: Our study revealed no common mutations between epithelial and stromal cells …

Endometriosis is characterized by ectopic endometrial-like epithelium and stroma, of which molecular characteristics remain to be fully elucidated. We sequenced 107 ovarian endometriotic and 82 normal uterine endometrial epithelium samples …

Levonorgestrel is used worldwide as an emergency oral contraceptive. There have been occasional reports of ectopic pregnancy after oral levonorgestrel use. We present a case of ectopic tubal pregnancy after the use of oral levonorgestrel as…

Abstract Endometriosis is a common complex inflammatory condition characterised by the presence of endometrium-like tissue outside the uterus, mainly in the pelvic area. It is associated with chronic pelvic pain and infertility, and its pat…

Endometriosis is a heritable hormone-dependent gynecological disorder, associated with severe pelvic pain and reduced fertility; however, its molecular mechanisms remain largely unknown. Here we perform a meta-analysis of 11 genome-wide ass…

BackgroundEndometrial cancer arising in adenomyosis (EC-AIA) is a rare entity of endometrial cancer, and its clinical significance has not been well studied. This study aimed to examine the tumor characteristics and survival outcomes of EC-…

Our previous genome-wide association study has demonstrated that single-nucleotide polymorphisms (SNPs) located in intronic and downstream regions of IL1A (interleukin 1α) were associated with the risk of endometriosis. These SNPs on the ge…

We conducted a genome-wide association meta-analysis of 4,604 endometriosis cases and 9,393 controls of Japanese and European ancestry. We show that rs12700667 on chromosome 7p15.2, previously found to associate with disease in Europeans, r…

BACKGROUND: Endometriotic cells display invasive characteristics, despite their benign histological appearance. Recently, the epithelial-mesenchymal transition, in which epithelial cells acquire mesenchymal and migratory properties, has att…

To identify susceptibility genes for endometriosis in Japanese women, genome-wide association (GWA) analysis was performed using two case-control cohorts genotyped with the Affymetrix Mapping 500K Array or Genome-Wide Human SNP Array 6.0. I…
