Hepatocellular carcinoma (HCC) is one of the most common malignant tumors and has the third highest mortality rate among malignancies in South Korea. Despite the continuing efforts for the early detection of HCC, the mortality rate and prognosis have not been improved yet. Its clinical behavior is quite different from other cancers. High recurrence rate after curative treatment might be the reason for poor prognosis. Several methods including chemoprevention, blocking the development of HCC, have been under investigations. The vaccine for hepatitis, in the form of primary prevention, is considered to be the most effective one inhibiting the development of liver disease. Furthermore, keeping away from hepatotoxic agents is another way for preventing liver cell injuries. Secondary prevention is to stop the development of HCC in chronic liver diseases. Since the level of DNA in hepatitis B virus (HBV) hepatitis patients is closely related with the development of HCC, it is helpful to lower the DNA level using anti-viral agents. In addition, IFN, one of the anti-viral agents, can inhibit HCV hepatitis from tumorigenesis. Cyclo-oxygenase (COX)-2 inhibitors are also alleged to have a function in interrupting the development of HCC. Tertiary prevention means the prevention of recurrence of HCC after successful treatment. Because of high recurrence rate, the prevention of recurrence should be one of the important factors affecting the prognosis of HCC. Up to now, COX inhibitors, retinoic acids, vitamin K2, glycyrrhizin epigallocatechin-3-gallate (EGCG), and ginseng had been reported to be effective for the chemoprevention of HCC. Further studies are required for an advancement in the prevention of HCC.
