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.

Abstract: A microfilter having a hydrophilic surface and suited for size-based capture and analysis of cells, such as circulating cancer cells, from whole blood and other human fluids is disclosed. The filter material is photo-definable, allowing the formation of precision pores by UV lithography. Exemplary embodiments provide a device that combines a microfilter with 3D nanotopography in culture scaffolds that mimic the 3D in vivo environment to better facilitate growth of captured cells.

Abstract: Circulating tumor cells (CTCs) are associated with metastasis of malignant solid tumors in a patient. Presented here is evidence that CTCs exhibit cell cycle phase variability and that there is a strong correlation between the number of CTCs in a mitotic cell cycle phase and the prospects for long term survival of the subject from which the cells were obtained. Also presented herein are methods of determining the mitotic cell cycle phase of CTCs from a patient having cancer and using the information in grading malignant solid tumors and predicting the likelihood of survival of the patient.
