Promising but preliminary

Soluble HER2 promotes chronic antigen-mediated CD8(+) T-cell dysfunction and limits immunotherapy response in HER2-low triple-negative breast cancer.

HER2-low triple-negative breast cancer (TNBC) has emerged as a clinically relevant subgroup with distinct therapeutic implications. Clinically, HER2-low tumors showed a significantly reduced pathological complete response rate following PD-1-based immunotherapy.
