FEATURES OF EXPRESSION OF TRANSFORMING GROWTH FACTOR BETA IN ESTROGEN-POSITIVE BREAST CANCER

Changes in the activity of growth factors and their receptors play a key role in shaping the response to treatment with anticancer hormonal drugs. The aim of this work was to study the relationship between the TGFβ1 and TGFβR1 expression and the progression of breast cancer (BC) during tamoxifen therapy.
