Background: The aim of this study was to evaluate whether molecular classification prognosticates treatment response in women with endometrial cancers and endometrial intraepithelial neoplasia (EIN) treated with levonorgestrel intrauterine system (LNG-IUS). Methods: Patients treated with LNG-IUS for endometrial cancer or EIN from 2013 to 2018 were evaluated. Using immunohistochemistry and single gene sequencing of POLE, patients were classified into four groups as per the Proactive Molecular Risk Classifier for Endometrial cancer (ProMisE): POLE-mutated, mismatch repair-deficient (MMRd), p53 wild type (p53wt), and p53-abnormal (p53abn). Groups were assessed relative to the primary outcome of progression or receipt of definitive treatment. Results: Fifty-eight subjects with endometrioid endometrial cancer or EIN treated with LNG-IUS were included. Of these, 22 subjects (37.9%) had endometrial cancer and 36 subjects (62.1%) had EIN. Per the ProMisE algorithm, 44 patients (75.9%) were classified as p53wt, 6 (10.3%) as MMRd, 4 (6.9%) as p53abn, and 4 (6.9%) as POLE-mutated. Of the 58 patients, 11 (19.0%) progressed or opted for definitive therapy. Median time to progression or definitive therapy was 7.5 months, with p53abn tumors having the shortest time to progression or definitive therapy. Conclusions: Molecular classification of endometrial cancer and EIN prior to management with LNG-IUS is feasible and may predict patients at risk of progression.

Endometrial Intraepithelial Neoplasia

Endometrial cancer represents worldwide the sixth most common malignant pathology in the female population, the endometroid type constitutes the most common form, usually developed from a typical sequence of endometrial hyperplasia secondary to sustained exposure to unopposed estrogens balanced by progestogens. Different classification systems for endometrial hyperplasia have been described, the most recent, published by the World Health Organization in 2014, proposes two categories: 1) hyperplasia without atypia, and 2) atypical hyperplasia or endometrial intraepithelial neoplasia. This classification avoids confusion due to the different terms in use and reflects a better understanding of the pathology behavior. Atypical hyperplasia or endometrial intraepithelial neoplasia is considered a precursor lesion to endometrial carcinoma type I. Health professionals must handle standardized terminology, accurately diagnose this entity, and ensure proper treatment of it. Keywords: Endometrial intraepithelial neoplasia, Endometrial hyperplasia, Atypical hyperplasia, Endometrial cancer.

Background: Endometrial hyperplasia is the precursor lesion of most endometrial cancers of endometrioid type. The most commonly used classication system for endometrial hyperplasia is WHO 1994 classication system in which architecture disruption and cytological atypia are used to identify four types of endometrial hyperplasia including simple or complex hyperplasia with or without atypia. Newer EIN diagnosis by cytological atypia is of great consideration for the progression to endometrial cancer. Material And Methods: The study consists of 100 cases of WHO classied endometrial hyperplasia for period of 4 yrs from 2015 to 2019. Type of sampling procedures- dilation & curettage, endometrial biopsy and fractional curettage. Objective: 1. To discuss revised criteria for recognition of endometrial intraepithelial neoplasia (EIN). 2. To nd out the sensitivity of endometrial intraepithelial neoplasia (EIN) classication in predicting the risk of malignancy. Results: This study consists of 100 cases of endometrial hyperplasia. Patients were mostly postmenopausal & presented with abnormal vaginal bleeding. From WHO classied endometrial lesions, 2 out of 35 cases of simple typical hyperplasia, 10 out of 14 cases of complex typical hyperplasia,12 out of 20 cases of simple atypical hyperplasia and 20 out of 21 cases of complex atypical hyperplasia were reclassied as EI N. Conclusion: To estimate the risk of progression to carcinoma and guide clinical management, the histo-pathologic diagnosis of endometrial hyperplastic lesion is very important, specially the diagnosis of EIN lesions. EIN carries a much greater risk of progression to endometrial cancer than other WHO classied endometrial hyperplasia.
