ESTROGEN AND PROGESTERONE RECEPTORS IN OVARIAN NEOPLASMS GYNECOLOGIC ONCOLOGY Ford, L. C., Berek, J. S., Lagasse, L. D., Hacker, N. F., Heins, Y., Esmailian, F., Leuchter, R. S., DELANGE, R. J. 1983; 15 (3): 299-304


The cytoplasmic receptors for 17 beta-estradiol (ER) and progesterone (PR) were measured in 39 malignant and 15 benign ovarian neoplasms. All eight endometroid carcinomas had positive ER sites, one-half contained PR. The number of ER binding sites decreased as tumor grade increased. Conversely, none of the 11 mucinous tumors contained either ER or PR receptors. One-half of the well-differentiated serous tumors had ER (57 +/- 23 fmole/mg protein) while none of the poorly differentiated tumors had measurable binding. In serous carcinomas, PR was only detected in well-differentiated lesions (447 +/- 240 fmole/mg protein). Only one of 15 benign neoplasms contained ER and PR receptors. Correlation of tumor grade and type may help to plan hormonal therapies in advanced ovarian malignancies.
