The effect of estrogen receptor status on survival in patients with endometrial cancer.

This study demonstrates a significantly increased survival time for women with estrogen receptor-positive adenocarcinoma of the endometrium when compared with that of those with estrogen receptor-negative tumors (p less than 0.05). This prognostic factor provides information which is additional to, and independent of, that provided by the histologic grade and myometrial penetration of the tumor.
