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.<i>See related article by Wang et al., p. 4287</i>.
