Abstract ABSTRACT - Sixty-five chemicals were coded and examined for their ability to induce lung tumors in strain A/St (laboratory A) or strain AJ (laboratory B) mice. Thirty-five chemicals were tested in laboratory A only, 8 in laboratory B only, and 24 in both laboratories. Two-year carcinogenicity test results as well as genotoxicity test data are available for most of these chemicals. There was poor interlaboratory agreement in strain A test results for the 24 chemicals tested in both laboratories. In addition, there was poor agreement between strain A test results from either laboratory and 2-year carcinogenicity test results or genotoxicity results. Possible explanations for these findings include selection of a large number of aromatic amines in the group of chemicals submitted for strain A testing, differences in strain A testing protocols and in statistical analysis of results from the two laboratories, low sensitivity of the strain A/St mice used in this particular study, and general problems inherent in comparing any relatively short-term animal tumor model with 2-year carcinogenicity tests. Since there is no absolute reference for carcinogenicity, no one test system is better than another. Carcinogenicity test data are relevant only to the test model employed.-JNCI 1986; 76:1101-1112.
