Estrogen and progesterone receptors expression in uterine malignant smooth muscle tumors: correlation with clinical outcome

J Chemother. 2003 Dec;15(6):596-602. doi: 10.1179/joc.2003.15.6.596.

Abstract

Uterine leiomyosarcomas are associated with a poor prognosis, although a considerable diversity in behavior may be found, and prolonged survival may occur. The aim of this study was to analyze the expression of estrogen (ER) and progesterone (PR) receptors in tumor specimens from uterine leiomyosarcomas, and to test their correlation with disease-free interval and cause-specific survival. This additional information may help the clinician differentiate between patients who have minimal risk of recurrence and those at greater risk of developing progressive disease. We examined specimens from 31 uterine leiomyosarcoma patients with clinical history and known follow-up. Disease-free interval and cause-specific survival rates were calculated according to the Kaplan-Meier method. According to univariate analysis, with Cox proportional hazards models, the ER expression (P=0.006 and P=0.016, respectively), PR expression (P=0.005 and P=0.016, respectively), and FIGO stage disease (P=0.011 and P=0.007, respectively) were independent predictors of the risk of recurrence and death from disease.
