摘要
Abstract Background: To delineate the levels of serum Hepatitis B virus (HBV) RNA in patients with HBV-related hepatocellular carcinoma (HCC) and study comparisons with those of individuals afflicted with cirrhosis. Methods: Adult patients diagnosed with HBV-related cirrhosis or HCC (initial diagnosis) were enrolled in the cross-sectional study. Serum HBV DNA level was quantified through a real-time polymerase chain reaction assay with a lower limit of quantification (LLQ) of 20 IU/ml. Additionally, serum HBV RNA was quantified employing RNA real-time fluorescence thermostatic amplification detection technology with LLQ of 100 copies/ml. Propensity score matching (PSM) was conducted to ensure balance in between-group confounders. Results: A total of 187 patients (47 with HCC and 140 with cirrhosis) were recruited, among whom 140 (74.9%) had undergone antiviral therapy prior to their inclusion, with varying durations. Serum HBV RNA was detectable in 89.4% of HCC patients at the time of carcinoma diagnosis. After PSM, individuals with HCC exhibited significantly elevated levels of serum HBV DNA and HBV RNA compared to those with cirrhosis (median lgHBV RNA 3.1 vs 2.0 copies/ml, P = 0.001). Subgroup analysis, including 38 patients who exhibited ultrasensitive HBV DNA negativity, revealed similar results (median lgHBV RNA 3.0 vs 0.0 copies/ml, P < 0.001). Conclusions: Serum HBV RNA levels were significantly higher in HBV-related HCC patients compared to cirrhotic patients. The presence of serum HBV RNA positivity or elevated levels was associated with the onset of HCC.
