Figure 3. High numbers of tumor-infiltrating γδ T cells predict poor overall survival and shorter relapse-free survival in breast cancer patients.

Kaplan-Meier curves for overall survival and relapse-free survival stratified by the high and low numbers of γδT cells in all breast cancer patients (A), ER-positive patients (B) and HER2-postive patients (C). The median expression of γδ T cells (9) in breast cancer tissues was used as a cutoff point to define γδ T cell-high and γδ T cell-low groups. A total of 46 breast cancer patients were analyzed. P values were calculated with use of the log-rank test.
