Abstract
Methods of using detection of PD-L1 expression by circulating cancer cells in the screening, monitoring, treatment and diagnosis of cancer in subjects are disclosed. The methods are based on assaying one or more of circulating tumor cells (CTCs), epithelial to mesenchymal transition CTCs (EMTCTCs), cancer associated macrophage-like cells (CAMLs), and cancer associated vascular endothelial cells (CAVEs) isolated from a subject having cancer for PD-L1 expression.
