Background: High-grade serous ovarian carcinoma (HGSOC) can be subdivided into four prognostic molecular subtypes based on gene expression: C1/Mesenchymal (C1.MES), C2/Immunoreactive (C2.IMM), C4/Differentiated (C4.DIF) and C5/Proliferative…

BACKGROUND: Malignant ascites is a common complication of advanced ovarian cancer (OC) and gastrointestinal cancer (GI), significantly impacting metastasis, quality of life, and survival. Increased intestinal permeability can lead to blood …

AIMS: Mesonephric-like adenocarcinoma (MLA) of the endometrium is often a diagnostic challenge, due to its morphological resemblance to other more common Müllerian neoplasms. This study aimed to retrospectively identify overlooked MLA in a …

Background: Deep endometriosis (DE) is a special form of endometriosis, one of the most common benign diseases in gynecology. In the specific case of DE, ectopic endometrium can be found not only in peritoneal but also in deeper tissue laye…

Background: Endometriosis is known to be a common chronic disease that often affects the quality of life of patients. Especially for deep endometriosis (DE), the most challenging form of the disease, surgery remains an important component o…

DNA methyltransferase and poly(ADP-ribose) polymerase inhibitors (DNMTis, PARPis) induce a stimulator of interferon (IFN) genes (STING)-dependent pathogen mimicry response (PMR) in ovarian (OC) and other cancers. We now show that combining …

BACKGROUND: Adhesions after endometriosis resection are frequent and the most common causes for chronic pain and secondary infertility. Primary results of our randomized controlled trial (RCT) on adhesion prevention after deep infiltrating …

Our objective was to test whether p53 expression status is associated with survival for women diagnosed with the most common ovarian carcinoma histotypes (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], and clear cell carci…

PURPOSE: Endometrioid ovarian carcinoma (ENOC) is the second most-common type of ovarian carcinoma, comprising 10%-20% of cases. Recently, the study of ENOC has benefitted from comparisons to endometrial carcinomas including defining ENOC w…

BACKGROUND: The poor prognosis of ovarian cancer patients is strongly related to peritoneal metastasis with the production of malignant ascites. However, it remains largely unclear how ascites in the peritoneal cavity influences tumor metab…

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…

PURPOSE: Adhesion formation after endometriosis surgery is a severe problem affecting up to 90% of patients. Possible complications include chronic pain, ileus, and secondary infertility. Therefore, effective adhesion prophylaxis is desirab…

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…

Abstract ARID1A (BAF250a) is a component of the SWI/SNF chromatin modifying complex, plays an important tumor suppressor role, and is considered prognostic in several malignancies. However, in ovarian carcinomas there are contradictory repo…

ARID1A (BAF250a) is a component of the SWI/SNF chromatin modifying complex, plays an important tumour suppressor role, and is considered prognostic in several malignancies. However, in ovarian carcinomas there are contradictory reports on i…

BACKGROUND: PTEN loss is a putative driver in histotypes of ovarian cancer (high-grade serous (HGSOC), endometrioid (ENOC), clear cell (CCOC), mucinous (MOC), low-grade serous (LGSOC)). We aimed to characterise PTEN expression as a biomarke…

Zielsetzung Bei bis zu 90% der Patientinnen kommt es nach Endometriose-Resektion zur Ausbildung von Adhäsionen. Diese wiederum können die Ursache für eine Vielzahl von Komplikationen sein, von denen die häufigsten Schmerzen, Darmobstruktion…

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 …

Zielsetzung Die chirurgische Therapie ist der Goldstandard in der Behandlung der TIE. Diese ist die anspruchsvollste und damit am schwierigsten zu behandelnde Endometrioseform. Unsere Untersuchung verfolgte das Ziel, den postoperativen Verl…

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…

DIE is the most challenging type of endometriosis and may be associated with severe pain and infertility. Complete minimally invasive resection is the gold standard treatment, leading to pain relief and increased fertility in a high number …

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…

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), …
