To first evaluate the levels of neutrophils in GC tissues, we examined CD15+ neutrophil numbers in tumoral tissues, peritumoral tissues, or non‐tumor tissues of patients with GC with various stages, and we found that GC patients demonstrated higher CD15+ neutrophil numbers in tumoral tissues than those in peritumoral tissues and/or non‐tumor tissues (Figure 1A and B). The gene discussed is FUT4; the disease is neoplasm.
