THE ROLE OF TUMOR-INFILTRATING LYMPHOCYTES IN TRIPLE NEGATIVE BREAST CANCER

Abstract

Triple-negative breast cancer (TNBC), which lacks the expression of hormone receptors and human epidermal growth factor receptor-2 (HER2) represents the breast cancer subtype with the poorest prognosis. We report a 58-year-old post-menopausal woman with triple-negative breast cancer (TNBC). Histopathological examination of core needle biopsy (CNB) of the right breast tumor showed breast infiltrative carcinoma with high Tils and negative axillary lymph nodes.
