Tumour‐infiltrating lymphocytes and expression of programmed death ligand 1 (PD‐L1) in melanoma brain metastases

Abstract

Melanoma BM showed considerable lymphocytic infiltrates and expression of PD-L1 in the majority of investigated specimens, with high PD-L1 expression found predominantly in regions of abundant inflammation. Our data indicate that clinical studies should investigate the value of checkpoint inhibitors in patients with melanoma BMs.
