Early Fibrosis but Late Tumor Stage and Worse Outcomes in Hepatocellular Carcinoma Patients Without Hepatitis B or Hepatitis C
Background and Aims
The features of non-viral, nonalcohol hepatocellular carcinoma (NBNC-HCC) remain elusive. The aim of this study was to investigate this clinical characteristics and overall survival of NBNC-HCC compared to hepatitis B- (HBV-HCC) and hepatitis C-related (HCV-HCC) HCC.
We analyzed the etiologies, fibrosis stages, clinical data, and outcomes of newly diagnosed patients with HCC.
A total of 1777 HCC patients were recruited, including 332 patients with NBNC-HCC, 682 patients with HBV-HCC, 680 patients with HCV-HCC, and 83 patients with HBV/HCV HCC. Patients with NBNC-HCC were older (69.9 ± 11.9 years). Patients with NBNC-HCC exhibited a higher prevalence of diabetes (43.9%) compared to the HBV-HCC (27.1%, p < 0.05) and HCV-HCC (30.2%, p < 0.05) groups. Compared to patients from the viral-related HCC groups, patients with NBNC-HCC exhibited a significantly lower fibrosis stage. NBNC-HCC patients exhibited a higher proportion of Barcelona Clinic Liver Cancer (BCLC) classification stage C and stage D compared to patients from the HBV-HCC and HCV-HCC groups. With a mean of 2.33 ± 2.31 years of follow-up, the median survival of patients with NBNC-HCC was 1.75 (95% CI 1.33–2.17) years, which was significantly lower than that of patients with HBV-HCC (p = 0.041) and HCV-HCC (p < 0.001).
Patients with NBNC-HCC have a higher risk of diabetes than patients with HCC of viral etiologies. Although patients with NBNC-HCC exhibited a milder fibrosis stage, their more advanced HCC stages and worse overall survival should be taken into consideration in clinical care.
