title: The distribution and prognostic implications of steroid receptors in endometrial carcinomas.
abstract: Estradiol receptors (ER) were measured in 71 and progesterone receptors (PR) in 62 primary endometrial carcinomas. ER were found in 62 (87%) and PR in 56 (90%) of the tumors. Fifty-six tumors were ER+/PR+ and 4 were ER-/PR-. The frequency of receptor positive tumors was not significantly correlated to histological grade. Highly differentiated tumors were, however, more often ER and PR rich (greater than or equal to 30 fmole/mg protein) as compared to poorly differentiated tumors. The median ER and PR values for grade I tumors were also significantly higher than for grade III tumors. No significant differences were found in the frequency of patients with ER or PR rich tumors in the different FIGO or surgical stages. The receptor status was not related to depth of myometrial infiltration. Recurrence rates and death rates were significantly higher in patients with PR poor as compared to those with PR rich tumors. This prognostic information could not be shown for ER.
