title: Local and systemic effects of 1-acetoxypropylpropylnitrosamine in Syrian golden hamsters.
abstract: 1-Acetoxypropylpropylnitrosamine (1-APPN) was synthesized and its biological effect examined in Syrian hamsters after subcutaneous (s.c.) administration. 1-APPN induced mesenchymal and epithelial neoplasms at the injection sites, as well as epithelial tumors in remote organs. Local neoplasms were a.c. sarcomas, mammary adenocarcinomas and Schwannomas, whereas tumors of the respiratory tract (papillary polyps, papillomas, adenomas, epidermoid carcinomas, and adenocarcinomas) were attributed to a systemic effect as were pancreas duct tumors. Neoplasms which originated in the upper digestive and genital tracts of females (papillomas, epidermoid carcinomas) may be related to a systemic and local effect of 1-APPN.
