[Anti-tumor effects of adriamycin, 4'-Epi-adriamycin, THP-adriamycin and mitoxantrone on rat mammary cancer induced by 7,12-dimethyl benz (A) anthracene].

Comparative studies of the anti-tumor effects of Adriamycin, 4'-Epi-Adriamycin, THP-Adriamycin and Mitoxantrone on rat mammary cancer induced by 7, 12-DMBA were performed. All 4 drugs were effective on the tumors, three administrations of Adriamycin, 4'-Epi-Adriamycin or Mitoxantrone at 1-week intervals showed remarkable tumor regression in each group. Mitoxantrone was not so effective in comparison with the other 3 drugs. Decrease in the body weight of the rats was most remarkably observed in the Mitoxantrone-treated group.
