Strain A mouse pulmonary tumor test results for chemicals previously tested in the National Cancer Institute carcinogenicity tests.

Sixty-five chemicals were coded and examined for their ability to induce lung tumors in strain A/St (laboratory A) or strain A/J (laboratory B) mice. Thirty-five chemicals were tested in laboratory A only, 6 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.

Classics in oncology. Survival in untreated and treated cancer.

During 1935 to 1951, a total of 75,494 cancer cases occurred among the inhabitants of Connecticut, of whom there were 2,000,000 in 1950. The five-year survival rate has improved gradually from 12 and 19 percent of all males and females, respectively, in 1935 to 1940, to 20 and 32 percent, respectively, during 1947 to 1951. This improvement is not due to earlier diagnosis of the cases, as can be seen from the similar distribution of localized and disseminated cases during the whole period of study.
