PFS with advanced HER2-positive breast cancer on immune related protein. Positive CD8, CFR^high group and negative PDL1 group had significantly longer PFS than negative CD8, CFR^low group and positive PDL1 group, respectively: a (p = 0.045, log-rank), c (p = 0.007, log-rank), e (p = 0.040, log-rank). Other immune related protein expression were not related to PFS: b FOXP3, d PD1, f CD163, g PTEN, h LAG3
