Etiological variations in hepatocellular carcinoma (HCC) exist across different geographic areas. To gain better control of HCC, we retrospectively studied the secular trends and geographic variations in hepatitis B virus (HBV)-related and hepatitis C virus (HCV)-related HCCs in Taiwan. A total of 18,423 HCC cases enrolled in 8 medical centers from 1981 to 2001 were reviewed. Overall, 67% of male HCC in Taiwan was related to HBV infection whereas 55.2% of female HCC in Taiwan was related to HCV infection. The mean age of patients with HBV-related HCC was 53.2 6 13.6 years, while the mean age of patients with HCV-related HCC was 65.1 6 9.1 years (p < 0.001). The male/female ratio was 6.4 for HBV-related HCC, while it was 1.7 for the HCV-related HCC (p < 0.001). The percentage of HBV-related HCC progressively decreased from 81.5 to 66.2% in males, and from 66.7 to 41.4% in females over the study period. Our study demonstrates that the percentage of HBV-related HCC has progressively decreased over the last 20 years. The relative decrease in HBV-related HCC was not due to a decrease in HBV-related HCC death. Instead, it was caused by an increase in HCV-related HCC. Prevention of new HCV infection and the treatment of chronic hepatitis C should be the primary goals, which will result in better control of HCC in the future, even in an HBV-endemic area like Taiwan. ' 2006 Wiley-Liss, Inc.Key words: hepatocellular carcinoma; hepatitis B virus; hepatitis C virus; secular trend; geographic variation; Taiwan Hepatocellular carcinoma (HCC) is one of the most common malignancies in the world, especially in sub-Saharan Africa and Southeast Asia. Since 1984, it has been the leading cause of cancer death in Taiwan, 1 accounting for approximately 7,000 death annually. In addition, around 8,000 new HCC cases are diagnosed each year. 2 High-risk groups for HCC include patients chronically infected with hepatitis B virus (HBV) or hepatitis C virus (HCV), liver cirrhosis patients, and people with a family history of HCC. Chronic HBV and HCV infections are the 2 major etiologies of HCC in Taiwan. 3 About 15-20% of the general population in Taiwan are chronic carriers of hepatitis B surface antigen (HBsAg). 4 HBV carriers have a 20-to 98-fold increased risk of HCC, 5,6 especially among the hepatitis B e antigen (HBeAg)-positive group. 7 A recent prospective study has further confirmed that positivity for HBeAg is associated with an increased risk of HCC. 8 To combat HBV infection in Taiwan, a mass immunization program has been launched on July 1, 1984, aiming first at the prevention of perinatal mother-to-infant, chronic HBV infection. 9 This nationwide vaccination program has markedly decreased the HBV carrier rate 10 and childhood HBVrelated HCCs (B-HCCs). 11 An 80-85% decrease in HCC among Taiwanese adults up to 3-4 decades later is anticipated. 12 The prevalence of anti-HCV antibody (anti-HCV) is 2-4% among the general population of Taiwan, 13 while it ranges from 0.95 to 2.2% in Taiwanese blood donors. 13,14 The anti-HCV prevalen...

“…Some authors indicated that active viral replication of HBV increases the risk of HCC in subjects with chronic HBV infection [5][6][7][8][9]. Yang et al [6] reported that the incidence of HCC was significantly higher in those who were HBsAg and HBeAg positive than in those who were HBsAg positive only.…”

Introduction The Asian Pacific Association for the Study of the Liver (APASL) convened an international working party on the management of hepatocellular carcinoma (HCC) in December 2008 to develop consensus recommendations. Methods The working party consisted of expert hepatologist, hepatobiliary surgeon, radiologist, and oncologist from Asian-Pacific region, who were requested to make drafts prior to the consensus meeting held at Bali, Indonesia on 4 December 2008. The quality of existing evidence and strength of recommendations were ranked from 1 (highest) to 5 (lowest) and from A (strongest) to D (weakest), respectively, according to the Oxford system of evidence-based approach for developing the consensus statements. 123Hepatol Int (2010) 4: 439-474 DOI 10.1007/s12072-010-9165-7 Results Participants of the consensus meeting assessed the quality of cited studies and assigned grades to the recommendation statements. Finalized recommendations were presented at the fourth APASL single topic conference on viral-related HCC at Bali, Indonesia and approved by the participants of the conference.

Hepatocellular carcinoma (HCC) is an important cause of death all over the world, more so in Asia and Africa. The representative data on epidemiology of HCC in India is very scanty and cancer is not a reportable disease in India and the cancer registries in India are mostly urban. 45 million people who are suffering from chronic Hepatitis B virus (HBV) infection and approximately 15 million people who are afflicted with chronic Hepatitis C virus (HCV) infection in India. HBV and HCV infection is considered an important etiologic factor in HCC. Positive association between HCC and consumption of alcohol where alcohol contribute as a cofactor for hepatotoxins and hepatitis viruses. Aflatoxin contamination in the diets, Hepatitis B virus infection and liver cirrhosis in Andhra Pradesh, India and direct chronic exposure to aflatoxins was shown to cause liver cirrhosis. Cirrhosis of liver of any cause lead to develop about 70%-90% of HCC. Aflatoxin interact synergistically with Hepatitis B virus (HBV)/Hepatitis C virus (HCV) infection which increase the risk of HCC. HBV infection, HBV infection with Aflatoxin exposure, viral infection and alcohol consumption leading to overt cirrhosis of the liver, alcohol consumption leading to cirrhosis of the liver with viral infection are the predominant risk factor for the development of HCC. HCV and alcohol are also associated with HCC in India. Indians develop diabetes at younger age, Asians have strong genetic susceptibility for type II diabetes. Diabetes mellitus is identified as a risk factor for HCC. Prevention of viral infection by universal vaccination against hepatitis virus, HCC surveillance program, preventing alcoholic liver diseases, fungal contamination of grains and ground crops to prevent basically Aflatoxin exposure are important measures to prevent liver diseases and HCC among those at risk.
