Endometrial hyperplasia is abnormal proliferation of the endometrial glands and stroma, defined as diffuse smooth thickening >10 mm One of the main. Endometrial hyperplasia involves the proliferation of endometrial glands that results in a greater than normal gland-to-stroma ratio. This results.

J Obstet Gynaecol Br Commonw. MPA prevents overgrowth in the uterine lining in postmenopausal women receiving estrogen hormone and decreases the risk of EH progression.

Endometrial Hyperplasia – ACOG

Multiple neutralizing antibodies and small chemical inhibitors of IGF-R1 are being studied in EC and could have applicability to treat EH if their toxicity profiles prove acceptability for a cancer prevention application [ 54 ]. Accordingly, further study is needed to determine the usefulness of GnRH analogues before it can be recommended for clinical use in patients with atypical hyperplasia [ ].

Metformin promotes progesterone receptor expression via inhibition of mammalian target of rapamycin mTOR in endometrial cancer cells. Contributed by Carlos Parra-Herran, M. Endometriosis of ovary Female infertility Anovulation Poor ovarian reserve Mittelschmerz Oophoritis Ovarian apoplexy Ovarian cyst Corpus luteum cyst Follicular cyst of ovary Theca lutein cyst Ovarian hyperstimulation syndrome Ovarian torsion.


Women’s Health Care Physicians

However, women with atypical EH or persistent EH without atypia that are symptomatic abnormal uterine bleeding are treated with hysterectomy. Combination with progestin or cyclic therapy of tamoxifen for breast cancer treatment needs more attention to prevent tamoxifen induced hyperplasia of endometrium.

Table 1 Different classification systems of endometrial hyperplasia. Pathophysiology and management of endometrial hyperplasia hjperplasia carcinoma.

Inhibition of tumor-associated fatty acid synthase activity antagonizes estradiol- and tamoxifen-induced agonist transactivation of estrogen receptor ER in human endometrial adenocarcinoma cells. Estrogen causes the lining to grow and thicken to prepare the uterus for pregnancy.

Overview of endometrial hyperplasia, risk factors, classification and treatment options. Various other old classifications are summarized in Table 1.

EH represents a continuum of histologically distinct processes, starting from simple EH without atypia and then progress to complex EH with atypia, followed by well-differentiated endometrial carcinoma Fig. Available therapeutic options for EH, such as progestin, danazol, genistein, metformin and GnRH therapy or surgery have restricted efficacy due to high cost, side effects and drug resistance.

Effect of the side chain and its position on the activity of 2,3-diaryl-2Hbenzopyrans. Several conditions associated with steroid hormone imbalances cause increased risk of EH and EC.

Endometrial hyperplasia

EM, a novel antiestrogen, acts as a pure antagonist of the transcriptional functions of estrogen receptors alpha and beta. Comparing letrozole with medroxyprogesterone acetate MPA as hormonal therapy for simple endometrial hyperplasia without atypia in adult and middle-aged women.


Postmenopausal, nulliparous, and infertile women are at greater risk of developing EH [ 4243 ]. In patients having only partial response, MPA may be continued for another 3 months orally at a dose of 10 mg, four times per day. Oxid Med Cell Longev. Moreover, therapeutic options for EH patients who wish to preserve fertility are challenging and require nonsurgical management.

Endometdium phase-III double-blind, randomized, multi-center study of norethisterone in postmenopausal women was conducted from to Find articles by Doris Mangiaracina Benbrook. Case 1 Case 1. Mechanisms involved in the evolution of progestin resistance in human endometrial hyperplasia–precursor of endometrial cancer. Towards such an approach, pure antiestrogens represent endocrine-targeted therapy whose mechanism of action involves competition with the ER ligands and ER down regulation.
