Study patients were divided into four groups according to their intratumoral α-SMA density and MVD values: group I (HCC/PC: n = 68/14), low α-SMA and low MVD; group II (HCC/PC: n = 84/15), high α-SMA and low MVD; group III (HCC/PC: n = 86/13), low α-SMA and high MVD; and group IV (HCC/PC: n = 67/15), high α-SMA and high MVD (see Table S9 in File S1, the detailed clinicopathological features of patients of different subgroups of α-SMA and MVD). The gene discussed is ACTA1; the disease is hepatocellular carcinoma.
