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]).
Clinicopathologic data and outcomes were compared retrospectively for HCC patients with hepatitis B virus, HCV, and NBC who had undergone hepatectomy.
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.
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.
"It remains controversial whether NBNC-HCC patients have comparable prognosis to HCC patients with HBV or HCV. In the previous studies, NBNC-HCC patients had a poorer prognosis than hepatitis virus-related HCC patients because NBNC-HCCs were often detected at an advanced stage incidentally without followup   . In contrast, a few "
[Show abstract][Hide abstract] ABSTRACT: We evaluated clinicopathological factors affecting survival and recurrence after initial hepatectomy in non-B non-C (NBNC) hepatocellular carcinoma (HCC) patients with comparison to hepatitis B or C virus, paying attention to relationship between alcohol consumption and histopathological findings. The medical records on the 201HCC patients who underwent initial hepatectomy between January 2000 and April 2013 were retrospectively reviewed. NBNC patients had higher prevalence of hypertension (47.4%), diabetes mellitus (35.5%), alcohol consumption (>20 g/day) (61.8%), and preserved liver function than hepatitis B or C patients. The 5-year survival rate of NBNC patients (74.1%) was significantly better than hepatitis B (49.1%) or C (65.0%) patients (NBNC versus B, P = 0.031). Among the NBNC patients, there was no relationship between alcohol consumption and clinicopathological findings including nonalcoholic fatty liver disease activity score (NAS). However, the 5-year OS and RFS rates in the alcohol-unrelated NBNC patients tend to be better than in the alcohol-related. By multivariate analysis, independent factors for OS in NBNC patients were Child-Pugh B/C, intrahepatic metastasis (im), and extrahepatic recurrence. NBNC patients, who were highly associated with lifestyle-related disease and preserved liver function, had significantly better prognosis compared to hepatitis B/C patients; however, there was no association between alcohol consumption and histopathological findings.
[Show abstract][Hide abstract] ABSTRACT: Background and aims: We compared clinicopathologic data and long-term clinical outcomes among patients with non-B and non-C hepatocellular carcinoma (NBNC-HCC) who underwent curative resection (group A, n=129), those with hepatitis B virus-related HCC (group B, n=62) and those with hepatitis C virus-related HCC (group C, n=284).
Methods: Clinicopathologic characteristics and cumulative overall survival (OS) and recurrence-free survival (RFS) after curative resection were compared among the three groups.
Results: The proportion of patients with non-liver cirrhosis (LC) or diabetes mellitus in group A was significantly higher than that in group B or group C. The mean maximum tumor size in group A was significantly larger than that of group B or group C. Cumulative 3-year OS rates after resection were 76% in group A, 79% in group B and 72% in group C (A vs. B, P=0.638; A vs. C, P=0.090; B vs. C, P=0.091; overall significance, P=0.088). The corresponding RFS rates after resection were 38% in group A, 36% in group B and 36% in group C (A vs. B, P=0.528; A vs. C, P=0.281; B vs. C, P=0.944; overall significance, P=0.557). In subgroup analyses in patients with LC, in those without LC and in those who satisfied the Milan criteria, similar results were obtained, i.e., the difference among the three groups did not reach significance in terms of OS and RFS.
Conclusion: Long-term clinical outcomes in patients NBNC-HCC after curative resection were comparable to those in patients with hepatitis virus-related HCC after curative resection.

[Show abstract][Hide abstract] ABSTRACT: Although most hepatocellular carcinoma (HCC) is related to viral infection, there is a substantial population of HCC patients (5-20%) who are negative for both markers of hepatitis B virus and hepatitis C virus infection [non-B, non-C (NBNC) hepatitis] in Japan and the incidence of NBNC-HCC has recently tended to increase. The most common cause of liver disease in developed countries is non‑alcoholic fatty liver disease (NAFLD), which includes non‑alcoholic steatohepatitis (NASH) and its related complications. Increased body mass index and diabetes mellitus are associated with developing NAFLD and NASH, which is a severe form of NAFLD. Furthermore, increasing clinical evidence supports the fact that NAFLD and NASH can progress to liver cirrhosis and even HCC. A detailed understanding of the epidemiology, etiology, molecular mechanism, clinical features and prognosis of NBNC-HCC could improve our screening and therapy of this disease. In this review, we primarily focus on clinical aspects of NBNC-HCC and refer to our current knowledge of this cancer.
