Abstract:
:Since our previous findings had indicated that the androgenic steroid medroxyprogesterone acetate (MPA) exerts potent inhibitory effects on 7,12-dimethylbenz(a)anthracene (DMBA)-induced tumor growth, we have studied the effect of low doses of MPA released from Depo-Provera and from 50:50 poly[DL-lactide-co-glycolide] microspheres in the same DMBA-induced tumor model. The present data show that single subcutaneous injection of a 4-month controlled-release formulation of biodegradable 50:50 poly[DL-lactide-co-glycolide] microspheres containing 10 mg of MPA giving serum levels of 3.14 +/- 0.32 ng/ml (8.12 +/- 0.83 nM) MPA causes a maximal or near-maximal 60% inhibition of tumor growth measured 56 days later. Such data suggest that controlled-release formulations giving constant and low blood levels of MPA could be used for the treatment of breast cancer in women. Such a low concentration of MPA should avoid the side effects observed with the high doses of the compound.
