Immune system B-cells may be better in predicting HER2-positive breast cancer treatment response

Researchers at UNC Lineberger Comprehensive Cancer Center and colleagues have found that measuring activation of immune-system B cells may be better than measuring either T-cell activation or the total number of immune cells in and around a tumor, called tumor-infiltrating lymphocytes (TILs), in predicting whether HER2-positive breast cancer responds to treatment.
