S100A9 and neoplasm: Table 1 shows that the tumoral S100A9+ cell number did not significantly correlate with patient sex, age, HBsAg, AFP, ALT, cirrhosis, differentiation, tumor multiplicity, tumor size, Barcelona Clinic Liver Cancer (BCLC) stage or TNM stage. However, nontumoral S100A9+ cell density, but not tumoral S100A9+ cell density, was associated with sex, tumor size, BCLC stage and TNM stage.
