A negative correlation for the GP88-positive IC was detected with tumor grade (rs = −0.171; p = 0.017), lymph node stage (rs = −0.196; p = 0.006), CK20 (rs = −0.189; p = 0.008), adjuvant chemotherapy (rs = −0.189; p = 0.008), and molecular subtype (rs = −0.349; p < 0.001; Supplementary Table S2). The gene discussed is GRN; the disease is neoplasm.
