Lymphocyte infiltration predicts survival in chemotherapy-naive, triple-negative breast cancer and identifies patients with intrinsically good prognosis: have we been bringing owls to Athens?

Invasive breast tumors that lack the expression of hormone receptors and lack overexpression/amplification of the human epidermal growth factor receptor 2 are defined as triple-negative breast cancers (TNBC) and warrant adjuvant chemotherapy. With the exception of very small tumors or patients not fit to receive cytotoxic treatment, there is ample clinical evidence to conform to these guidelines. Although TNBC constitute a group of biologically...
