Thorotrast induced liver cancer: Update of the German Thorotrast study

摘要

The German Thorotrast study was started in 1968. It com- prises 2, 326 Thorotrast patients and 1. 890 contemporary matched controls. 899 Thorotrast patients and 662 patients of the control group have been examined clinically and biophysi- cally every two years. The evaluation of the causes of death demonstrates a statistically significant excess rate of malignant liver tumors, liver cirrhoses, myeloid leukaemias and bone marrow failures.
