Predictive ability of estrogen receptor (ER), progesterone receptor (PR), COX-2, Mlh1, and Bcl-2 expressions for regression and relapse of endometrial hyperplasia treated with LNG-IUS: A prospective cohort study

We found that poor expression of ER and PR is weakly associated with persisting endometrial hyperplasia and COX-2, Mlh1, and Bcl-2 expressions are not predictive. None of the biomarkers is predictive for relapse in women with endometrial hyperplasia treated with LNG-IUS.
