Myeloid Resistance is not Futile: Biomarkers of Immunotherapy in Bladder Cancer.

Abstract

The majority of patients with urothelial cancer do not respond to immune checkpoint blockade directed at the PD-(L)1 axis. Recently, robust profiling data were used to derive predictive biomarker signatures for both protumorigenic immunity and adaptive antitumor immunity; combining these has greater predictive power than either alone. Clinically, these results suggest that myeloid cells may be primary drivers of nonresponsiveness in urothelial cancer.See related article by Wang et al., p. 4287.
