[Oestrogen receptors determination in human breast cancer (author's transl)].

The AA. refer about the assessment of a charcoal-dextran method for the determination of oestrogens receptors in human breast cancer. Corrections for low affinity binding components are performed measuring bound 3H-17 beta estradiol in the absence and presence of non-radioactive 17 beta estradiol or diethylstilbestrol; the method has been previously studied on samples from pregnant rabbit uterus and then applied on human mammary tumors. Results achieved with the routine-utilisation of the present method are reported.
