Description

Immune checkpoint drugs have changed the outlook for esophageal squamous cell cancer, but many patients still do not respond. Kosuke Kanemitsu and co-authors search tumor samples from forty-five treated patients for signs that separate responders from the rest. They stain the samples for immune markers, the PD-L1 signal, and the HLA molecules that present targets to immune cells.

High PD-L1 on tumor cells and on the macrophages around them marked the patients who benefited. Those tumors also drew in more T cells, though cell counts alone did not predict response. Responders oddly showed less of one HLA family and stray amounts of another. Gene data from single cells linked macrophage PD-L1 to T-cell growth. The authors argue both marker families belong in prediction tests.
