PDCD1LG2 and gastric cancer: Herein, we show that a novel FasL+PD‐L2+ neutrophil subset that constitutes more than 20% of all neutrophils in advanced GC exhibits a unique phenotype differing from that of the conventional FasL−PD‐L2− peripheral neutrophils and, that their infiltration in GC is associated with disease progression and is negatively correlated with patient survival following surgery.
