Estrogen and progesterone receptor expression in patients with uterine leiomyosarcoma and correlation with different clinicopathological parameters.

Abstract

In conclusion, the present study observed that estrogen and progesterone receptors are frequently expressed in uterine leiomyosarcoma. However, their expression did not correlate with clinical stage, age, vascular space involvement and recurrence of disease and had no influence on overall and disease-free survival. Despite the lack of prognostic impact, further clinical studies with larger numbers of cases need to be performed to verify if estrogen and progesterone receptor-positive tumors can be treated by hormonal manipulation.
