Prognostic and predictive value of tumor-infiltrating lymphocytes in a phase III randomized adjuvant breast cancer trial in node-positive breast cancer comparing the addition of docetaxel to doxorubicin with doxorubicin-based chemotherapy: BIG 02-98

Tumor-infiltrating lymphocytes, breast cancer subtypes and therapeutic efficacy

By analyzing over 2000 samples from a randomized clinical trial, we have recently associated high levels of tumor-infiltrating lymphocytes with an excellent prognosis among triple negative breast cancer patients as well with improved clinical responses to immunogenic chemotherapy among patients bearing HER2 over-expression. These findings suggest that immunomodulation could represent a new approach to treat these aggressive breast cancer subtypes.
