Estrogen receptor (ER) and progesterone receptor (PR) levels have been measured in 374
tumors from patients with primary breast cancer and compared with axillary nodal status and …

It has been demonstrated that progesterone receptor (PR) is at least as valuable as estrogen
receptor (ER) for predicting the outcome in breast cancer patients. Retrospective analysis …

The value of estrogen receptor (ER) measurements for predicting recurrence and survival
rates in primary breast cancer was examined in 121 women who were followed from 5 to 12 …

The value of estrogen receptor (ER) analysis in primary breast cancer samples as a
potential prognostic factor was examined in three clinical situations: time to recurrence in …

Abstract From October 1977 to December 1983, estrogen receptor (ER) and progesterone
receptor (PR) levels were measured in 645 tumors from women with primary, unilateral …

To investigate whether or not hormone receptor determination gives independent prognostic
information for long term survival of patients with carcinoma of the breast, we studied 1,392 …

The aims of this study were as follows: to confirm that the presence of estrogen (ER) and
progesterone (PgR) receptors is an indicator of clinical behavior of human breast cancer …

Estradiol receptor alone or estradiol and progesterone receptors (ER, PgR) have been
measured in tumors from 307 women who were treated for primary breast adenocarcinoma …

Our present state of knowledge regarding estrogen and progesterone receptors (ER and
PgR) has led to changes in. treatment strategies: patients without receptors in their tumor …

The presence of estrogen receptors in breast cancers is now accepted as a predictor of
extended disease-free survival, but the relative value of progesterone receptors for this …
