Based on uc001ncr and AX800134 expression, these lncRNAs were determined to accurately diagnose HBV-positive HCC (AUC = 0.9494), including patients with an AFP of 400 ng/ml (AUC = 0.9371), indicating potential usefulness as biomarkers in diagnosing HCC [42]. The gene discussed is AFP; the disease is hepatocellular carcinoma.
