The anticarcinogenic efficacy of the polyamine biosynthesis inhibitor, alpha-difluoromethylornithine (DFMO), was assessed in three rodent models of human epithelial cancer. In DMBA-induced female, Sprague-Dawley rats, DMFO treatment (3.2 or 6.4 g/kg diet) for 180 days significantly inhibited mammary carcinogenesis and reduced tumor-related intercurrent mortality compared to untreated controls. In male, C57BL/6x DBA/2F1 mice induced with N-butyl-N(4-hydroxybutyl)nitrosamine (OH-BBN), DFMO treatment (2 or 4 g/kg diet) concurrent with the period of carcinogen administration significantly reduced the incidence and severity of urinary bladder carcinomas. In methylnitrosourea (MNU)-induced male Syrian golden hamsters, DFMO (3.2 g/kg diet) numerically reduced the incidence and size of tracheal carcinoma relative to untreated controls. DFMO-mediated toxicity was not evident in any of the animals on study, although a slight reduction in mean body weight gain was evident in rats and mice.
