Objective Multiple forms of endometriosis have been shown to harbour somatic cancer-driver alterations. Previous studies have focused on the inter-patient heterogeneity of genetic alterations in endometriosis, analyzing lesions collected fr…

OBJECTIVE: To investigate the heterogeneity of somatic cancer-driver mutations within patients and across endometriosis types. DESIGN: A single-center cohort, retrospective study. SETTING: Tertiary specialist-care center at a university h…

Abstract Endometriosis symptoms are heterogeneous with controversy on whether it constitutes a single disease or multiple distinct types. Our previous work found recurrent somatic cancer-driver alterations in endometriosis; however, these h…

Endometriosis has yielded controversy on whether it constitutes a single disease or distinct types. Current classification systems poorly correlate with the severity of symptoms and do not provide prognostic tools that can guide management …

The advent of next generation sequencing has vastly improved the resolution of mutation detection, thereby both increasing the resolution of the analysis of cancer tissues and shining light on the existence of somatic driver mutations in no…

Abstract The presence of somatic driver mutations in endometriosis has previously been believed to represent early events in transformation, however our group and others have described such mutations in roughly one-third of cases of deep in…

Endometriosis is a common gynecological disease characterized by the ectopic growth of endometrium-like tissue. Despite the widespread prevalence of endometriosis, its pathogenesis remains poorly understood. A recent study by Noë et al prov…

The clinical presentation of endometriosis is highly heterogeneous. In a landmark study we have shown somatic cancer-driver mutations in deep infiltrating endometriosis, with at least one case having multiple sites harboring the same driver…

STUDY QUESTION: Does incisional endometriosis (IE) harbor somatic cancer-driver mutations? SUMMARY ANSWER: We found that approximately one-quarter of IE cases harbor somatic-cancer mutations, which commonly affect components of the MAPK/RAS…

Endometriosis is a common gynecological disease and precursor of clear cell and endometrioid ovarian carcinomas. We recently demonstrated that one form of endometriosis with little malignant potential, deep infiltrating endometriosis (DE), …

Introduction: Endometriosis is a chronic, inflammatory gynecological disease characterized by the ectopic growth of endometrial-like tissue. Previous studies have established endometriosis as the precursor to clear cell and endometrioid ova…

Abstract BACKGROUND: Endometriosis affects ~10% of reproductive–aged women and is characterized by extra–uterine biphasic growth of uterine endometrial epithelium and stroma. Endometriosis is widely considered to be a hormonally–dependent i…

BACKGROUND: Endometriosis, defined as the presence of ectopic endometrial stroma and epithelium, affects approximately 10% of reproductive-age women and can cause pelvic pain and infertility. Endometriotic lesions are considered to be benig…
