MIB1 as a possible predictor of recurrence in low-grade endometrial stromal sarcoma of the uterus.

Objective: Immunohistochemical analysis of MIB1, p53, estrogen, and progesterone receptors can provide prognostic information in endometrial adenocarcinoma. Since predictors of recurrence for low-grade endometrial stromal sarcoma (LESS) are still unknown, a battery of immunostains was performed to find markers, which might be useful to predict prognosis.

Methods: Eleven patients with an average age of 43.
