Perspectives in scintigraphic detection of gynecologic tumors using labeled estrogen

After having succeeded in imaging the prostate with 131I-Estracyt in our former experiments we tried to use the same method for scanning gynecological tumors. In about fifty per cent of the patients (34 cases) there was a convenient accumulation of the labeled estrogen, first of all the adenoid tumors, myomas of uteri and carcinomas can take up this radiopharmacon. Though the number of cases is rather low it is to be concluded that tumors of hormonal dependence can be scanned using estrogen hormon. Further investigations are in progress.
