  • Title: Clinicopathologic characteristics of patients with non-B non-C hepatitis virus hepatocellular carcinoma after hepatectomy.
    Author: Kaibori M, Ishizaki M, Matsui K, Kwon AH.
    Journal: Am J Surg; 2012 Sep; 204(3):300-7. PubMed ID: 22591698.
    Abstract:
    BACKGROUND: A substantial population of hepatocellular carcinoma (HCC) patients is negative for markers of hepatitis B virus and hepatitis C virus (HCV) infection (non-B non-C hepatitis virus [NBC]). METHODS: Clinicopathologic data and outcomes were compared retrospectively for HCC patients with hepatitis B virus, HCV, and NBC who had undergone hepatectomy. RESULTS: The TNM stage was significantly higher, and the prevalence of cirrhosis was significantly lower, in the NBC group compared with the HCV group. Among patients with a maximum tumor diameter of 5 cm or less, the survival rates were significantly higher in the NBC group than in the HCV group. Multivariate analysis revealed that preoperative serum des-gamma-carboxy prothrombin (DCP) level was a prognostic factor for survival in NBC-HCC patients. The DCP/tumor size ratio was significantly higher in NBC-HCC patients with normal liver histology than in patients with hepatitis or cirrhosis. CONCLUSIONS: NBC-HCC patients had more advanced tumors compared with HCV-HCC patients, but significantly higher survival rates. Measurement of DCP potentially is significant for early diagnosis of NBC HCC, which may increase the chance of curative therapy without recurrence.
