Tissue microarray immunohistochemical expression of estrogen, progesterone, and androgen receptors in uterine leiomyomata and leiomyosarcoma

Abstract

The rate of ER and PR expression was found to be significantly less in uterine LMS compared with LMA. ER, PR, and AR expression was observed in approximately 30-40% of uterine LMS cases. In the current series, PR and AR expression appeared to be associated with disease-free survival but were not found to correlate with overall survival.
