title: [Modern prospects for molecular-biochemical methods for evaluating biological "behavior" of breast neoplasms].
abstract: The paper presents recent data on the role of oncogenes and suppressive genes, receptors of steroidal hormones, secretory protein pS2, cathepsin D, urokinase and tissue plasminogen activators and their inhibitor PAI-I, polypeptide growth factors and somatostatin and their receptors in the evaluation of proliferative activity and drug therapy responses and in the prediction of disease and on the simultaneous estimation of the limited number of mutually complementing parameters that can characterize the proliferative activity of a tumor, its metastatic potential and sensitivity to different types of overall and regional regulation. The main task for investigators engaged in this area is to choose a qualitatively and quantitatively optimal ratio of molecular markers of breast cancer to evaluate the biological behavior of a tumor.
