Cancer mortality of thorotrast patients in Japan: the second series updated 1998.
The 150 male patients exposed to Thorotrast who were confirmed by a 1975-1978 national survey with diagnostic X rays of 50,860 war-wounded soldiers were followed up between 1979 and 1998 (Aichi series or second series). Age-adjusted rate ratios of deaths from all causes were 3.0 times higher in Thorotrast patients compared to controls; this was statistically significant. Rate ratios for liver cancer, liver cirrhosis and leukemia were 35.0, 7.5 and 18.2, respectively.
