ABSTRACT
The immune system is very critical in suppression of cancer development. The composition of breast cancer-infiltrating lymphocytes has been widely investigated so far and it is accepted that the presence of high tumor-infiltrating lymphocytes (TILs) is associated with improved prognoses. The correlation between various TIL subpopulations and experimentally observed responses is still characterized by a certain grade of controversy. Modulating the immune system is promising treatment strategy in breast cancer, particularly in HER2 positive and triple-negative molecular subtypes. However, there is still much to be done to implement immunotherapy in this disease.
