PROGNOSTIC VALUE OF EXPRESSION OF ANDROGENETIC RECEPTORS IN DIFFERENT MOLECULAR TYPES OF BREAST CANCER

Introduction. So far in the literature there is no consensus on the relationship between the level of androgens and their metabolites in various biological fluids and tissues with the development of breast cancer. As suggested by many researchers, determining the level of androgenetic receptors (AR) in the tumor in patients with breast cancer are able to access a number of promising directions in the study of prognosis of the disease and the search for new approaches to endocrine therapy of different molecular subtypes of breast cancer. Objective. To evaluate the clinical and prognostic significance of the immunohistochemical expression of AR in different molecular types of breast cancer. Materials and methods. In the present work we have studied the expression of AR in tumor tissue in patients of different molecular types of breast cancer. Results. The risk of death in patients with AR-positive breast cancer is 88 % lower than in patients with AR-negative tumors. Conclusion. It was concluded that the study of the expression of AR, is a promising direction not only in the assessment of the prognosis of the disease, but when searching for additional approaches to the treatment of breast cancer.
