摘要

The study described in the report was initiated after results from two earlier studies revealed discrepancies in the rate at which two C3H substrains (C3H/HeJ and C3H/HeN-MTV+) developed mammary tumors. In addition to the substrain difference, the age at the start of DES treatment and several other experimental variables also differed between the two studies. An evaluation of the impact on mammary tumorigenesis of some of these experimental variables has already been reported (Greenman, Highman, and Schieferstein, 1983) for the two substrains in question. However, a third C3H substrain (C3H/HeN-MTV-) was to be used in another DES chronic-feeding study designed for implementation at the National Center for Toxicological Research (NCTR). The logistics involved in the production, assignment, and start of dosing of mice in the latter experiment resulted in a 7-day age range at the start of dosing. Thus, the present study was designed to evaluate the influence of age at the onset of DES treatment on tumorigenic responses in C3H/HeN-MTV- female mice.
