Abstract

BACKGROUND AND AIM: Hepatitis C virus (HCV) is an important cause of hepatocellular carcinoma (HCC) in Asians; however, it is often overlooked due to the high prevalence of hepatitis B virus in Asians. This study examines HCV-related HCC in Asians.

METHODS: We conducted a retrospective cohort study of 792 consecutive Asian (n = 220) and non-Asian (n = 572) patients with HCV-related HCC identified at Stanford University Medical Center using International Classification of Diseases-9 diagnosis between July 1996 and June 2012.

RESULTS: Asian patients were much older [66 (38-88) vs. 56 (31-87) years, P < 0.0001] and more likely to be female (33 vs. 19 %, P < 0.0001). A larger proportion of Asians were diagnosed with HCC within 2 years of HCV diagnosis (35 vs. 20 %, P = 0.001). Asian patients were more likely to undergo palliative therapy (46 vs. 28 %) and less likely to be listed for liver transplantation (20 vs. 48 %, P < 0.001), despite similar rates of meeting Milan criteria (52 vs. 58 %, P = 0.16). Overall, there was a trend for higher median survival rates in Asians (30 vs. 21 months, P = 0.091). Asians had higher long-term survival with palliative therapy only (5-year survival: 28 vs. 10 %, P < 0.0001); however, survival was similar among patients listed for liver transplantation.

CONCLUSIONS: There were distinct differences in clinical presentations of Asian and non-Asian patients with HCV-related HCC. Asians with HCV-related HCC are less likely to undergo liver transplantation and more likely to have delayed HCV diagnosis. Improved strategies in HCV screening in Asians are needed, as it may lead to earlier diagnosis and treatment of HCV infection and possible prevention of HCC development.
