The expression analysis of the estrogen and progesterone receptors in endometrial carcinomas.

The aim of the study was the analysis of expression of estrogen (ER) and progesterone (PR) receptors in endometrial carcinomas. The expression of each of the receptors was examined with reference to such parameters as: patients' age, the relation to menopause, histological type and grading, the depth of myometrial infiltration and the presence of endometrial hyperplasia adjacent to the tumour. There were found very significant correlations between the degree of histological grading and expression of ER and PR and between values of index ER and PR. There was obtained correlation between the expression and endometrial hyperplasia only for PR.
