title: The carcinogenic effect of 1,1-diethyl-3-methyl-3-nitrosourea in Syrian golden hamsters.
abstract: 1,1-Diethyl-3-methyl-3-nitrosourea (Et2MNU) was subcutaneously injected in Syrian golden hamsters once weekly for 52 weeks. The animals developed mainly papillomas and squamous cell carcinomas of the nasal cavity and forestomach and hemangioendotheliomas of the spleen. Although survival time and tumour latency showed dose-dependency, tumour incidence did not.
