A high level of HEIH has been found significantly associated with HBV-related HCC recurrence (HR = 2.1; 95% CI: 1.2–3.7) [33], while another study found HCC patients with lower levels of GAS5 in tumor tissue had a worse overall survival than patients with higher expression (HR = 2.4; 95% CI: 1.6–4.1) [32]. The gene discussed is HEIH; the disease is hepatocellular carcinoma.
