CD4 and breast carcinoma: In breast cancer patients, a higher proportion of M0 macrophages indicated decreased DFS (HR=1.67, 95% CI 1.22~2.27, p<0.01), while increased OS was associated with relatively higher fractions of resting memory CD4+ T cells (HR=0.70, 95% CI 0.55~0.90, p=0.02) and γδ T cells (HR=0.66, 95% CI 0.51~0.85, p<0.01).
