1. A method of selecting a treatment for a subject having cancer, comprising: assaying cancer associated macrophage-like cells (CAMLs) and circulating tumor cells (CTCs), and optionally one or more of epithelial to mesenchymal transition CTCs (EMTCTCs) and cancer associated vascular endothelial cells (CAVEs), isolated from a subject having cancer for PD-L1 expression, wherein when PD-L1 expression is detected, the subject is identified as a subject to receive an immune checkpoint inhibitor treatment, and wherein the immune checkpoint inhibitor is an antibody.
