Abstract

The effect of dose was evaluated for the bladder carcinogenicity of N-[4-(5-nitro-2-furyl)-2-thiazolyl] formamide (FANFT). The chemical was fed to male weanling F344 rats for 30 weeks followed by 74 weeks of control diet. The incidences of bladder carcinoma were 100, 100, 87, 0, 0 and 0% for doses of 0.2, 0.1, 0.05, 0.01, 0.005 and 0.001%, respectively. There was an inverse relationship between dose and latency period. There was no increased incidence of tumors of other tissues.
