[Hormonal factors in the prediction of hormonedependency of breast cancer]

Abstract

Biological diagnostic of hormonedependency of breast tumors is important for the choice of treatment. Modifications of the metabolism of steroids, oestrogens, androgens, and glucocorticoids allowed a first approach. More recently, investigations have been made on breast tissue receptors for hormones that are involved in the growth of the normal gland. It is actually suggested that one could predict the hormonedependency of a tumor when it contains both receptors for oestradiol and progesterone.
