Based on immunohistochemical staining of DC‐SIGN (hereafter DCsign: DC‐specific ICAM‐3‐grabbing nonintegrin; CD209)‐positive cells, our group recently demonstrated morphological differences between the sentinel and non‐sentinel nodes of early gastric cancer patients without metastasis (Sonoda et al., 2025). The gene discussed is CD209; the disease is gastric cancer.
