Abstract
In order to make a more individualized therapy possible in endometrial cancer we investigated the prognostic ability of steroid receptor concentration and the DNA content in individual cells as measured by flow cytometry. We found that although the steroid receptor concentration was a prognostic parameter, the DNA content proved to be a better parameter than all other known prognostic parameters in endometrial carcinomas stage I—II, Thus it was possible to divide the tumors into three groups; 1) diploid tumors with a relapse rate of 6%, 2) aneuploid tumors with a high estradiol receptor concentration and without myo-metrial invasion of more than the inner third, and with a relapse rate of 18%, 3) aneuploid tumors, poorly differentiated with a low estradiol receptor concentration or myometrial invasion and with a relapse rate of 44%.
