ConclusionsEndometriosis is not independently associated with the prognosis of OEC and OCCC among young patients. The intrinsic relationship between endometriosis and ovarian cancer warrants further investigation.

Purpose of review To investigate the JZE alterations in gynecological and obstetrical disorders and impact on diagnosis, prognosis and treatment. Recent findings JZE was found to be significantly extended in patients with endometriosis, leading to the conclusion that endometriosis is a primary disease of the uterus, much like adenomyosis. Statistical correlation was then demonstrated between the severity of endometriosis and the depth of the adenomyosis infiltrates, hence the thickening of the JZE. Stem cells, predominantly found in the JZE were also found in histological sections of leiomyoma, suggested to be the ori...

The mechanism by which endometriosis-associated ovarian cancer (EAOC) avoids anti-tumor immune surveillance by macrophages remains unclear, but CD47 is a very important immune checkpoint for macrophage phagocytosis. Therefore, we collected 36 clinical ovaria...

Abstract Endometriosis is considered a high risk factor for the development of ovarian carcinoma, including clear cell and endometrioid malignancies. The mechanism by which endometriosis-associated ovarian cancer (EAOC) avoids anti-tumor immune surveillance by macrophages remains unclear, but CD47 is a very important immune checkpoint for macrophage phagocytosis. Therefore, we collected 36 clinical ovarian samples and detected the protein profile of CD47 by immunohistochemistry and analyzed the correlation with clinical pathological features using statistical software. We found that CD47 expression was relatively ...

This study investigated the clinical-pathologic characteristics and outcome of EAOC compared with other ovarian carcinomas that are not associated with endometriosis (non-EAOC) in a large cohort. Seven hundred two patients meeting the inclusion criteria were further subclassified as group I when patients had ovarian carcinoma associated with or arising within endometriosis (EAOC) and group II when patients had non-EAOC. Age, gross features, histologic type, International Federation of Gynecology and Obstetrics stage, and disease-free survival (DFS) were compared between the groups. One hundred sixty-eight (23.9%) patients ...

Endometrium is the mucosal lining of the uterus which expressed a cyclic process of proliferation, secretion and scaling under the control of hormones secreted by the ovary, and it also plays an indispensable role in the embryo implantation, the constitution of fetal-maternal interface, and the maintaining of pregnancy. In pathophysiological conditions, the abnormality or disorder of endometrium may lead to endometrium-related diseases, such as endometriosis, endometrium hyperplasia and even endometrial carcinoma. In recent years, more and more evidence revealed that autophagy exists in both the endometrium stroma cells an...

This review is an appraisal of the current state of knowledge of 2 enigmatic histotypes of ovarian carcinoma: endometrioid and clear cell carcinoma. Both show an association endometriosis and the hereditary nonpolyposis colorectal cancer (Lynch) syndrome, and both typically present at an early stage. Pathologic and immunohistochemical features that distinguish these tumors from high-grade serous carcinomas, each other, and other potential mimics are discussed, as are staging, grading, and molecular pathogenesis.

ConclusionsEAOC is a distinct disease that affects women with benign endometriosis at younger ages than classic ovarian cancer. Understanding the imaging features of malignant transformation of endometriosis is essential for early diagnosis and timely definitive treatment.

CONCLUSIONS: The EAOC patients were often diagnosed at a younger age, an earlier stage, and related to nulliparity and infertility. Patients with EAOC had a better prognosis than non-EAOC, early stage rather than association with endometriosis may be the driver of survival. PMID: 30913953 [PubMed - as supplied by publisher]
