HCC patients with tumors expressing KIF23 V1 tended to correlate with better 3-year survival, but without statistical significance (P = 0.1604, Fig. 5a), while KIF23 V1-expressing patients had significantly longer OS (35 months) than the patients whose tumors did not express KIF23 V1 (15 months) (P = 0.0052, Fig. 5b). The gene discussed is KIF23; the disease is hepatocellular carcinoma.
