[Epidemiology of malignant liver tumors].
Interpretation of descriptive statistics on liver cancer is affected by misclassification problems, evolving diagnostic procedures and changes in international classifications. Chronic infection with virus B and aflatoxin are major determinants for liver cancer in high-risk areas. In low and intermediate risk areas, including Italy, alcohol and cirrhosis are the most important risk factors. Preventive measures are neonatal vaccination against hepatitis B, reduction in aflatoxin contamination of foods, alcohol and tobacco consumption. Screening programs cannot be recommended as a measure of public health, particularly in western countries.
