The presence of androgen receptor (AR) in the cells of triple negative breast cancer was detected immunohistochemically. Androgen receptors were found in 11 (22%) from 50 cases of triple-negative breast cancer. The number of malignant cells with androgen receptor from the total breast cancer cells number was from 1 to 55%, the mean value ľ 25 ▒ 22%.
There were not metastases in regional lymph nodes in any case of the AR+ triple-negative breast cancer. AR+ cells of the triple negative breast cancer metastasize to regional lymph nodes significantly slower compared with AR-cells of the triple negative breast cancer. There were metastases to the regional lymph nodes in 5 cases (12.8%), distant metastases - in 1 case (2.6%) in patients with AR-triple negative breast cancer. The androgen receptors determination in breast cancer cells by immunohistochemistry is prognostically valuable.
