Where this comes from

Abstract

In a retrospective analysis of patients with unresectable melanoma, higher pretreatment tissue densities of CD16+ macrophages were associated with clinical benefit from combined CTLA-4 and PD-1 blockade. With further validation, this biomarker could serve as a tool in selecting between immune checkpoint inhibitor regimens. See related article by Lee et al., p. 2513.
