子宫内膜癌(EC)是女性生殖系统三大恶性肿瘤之一,约3%~14%发生在40岁以下的年轻女性,其中80%以上未曾生育或仍有生育愿望。如何保留年轻EC患者的女性特征和生育功能是当前妇科临床亟待解决的问题。左炔诺孕酮宫内缓释系统(LNG-IUS)通过每天恒定释放20μg的左炔诺孕酮至宫腔,拮抗雌激素作用,逆转增生或癌变的内膜组织,在早期EC保留生育功能治疗中的应用越来越受到关注。本文重点就其治疗机制、适应
Endometrial cancer (EC) is one of the three major malignant tumors of the female reproductive system, about 3% to 14% of young women under the age of 40, of whom more than 80% have never had any childbirth or still have a desire to reproduce. How to preserve the female characteristics and reproductive function in young patients with EC is the urgent problem to be solved in the gynecological clinic. The levonorgestrel-releasing intrauterine release system (LNG-IUS) retains fertility in early EC by consistently releasing 20 μg of levonorgestrel per day to the uterine cavity to antagonize estrogen effects and reverse hyperplastic or cancerous endometrial tissue The application of treatment is receiving more and more attention. This article focuses on its treatment mechanism, adaptation
