dc.description.abstract | Background—Combination cytotoxic agents in breast cancer carry dose-limiting toxicities. We hypothesize that nanocarrier-conjugated doxorubicin and cisplatin will have improved tumor efficacy with decreased systemic toxicity over standard drugs, even at lower doses.Methods—Female Nu/Nu mice were injected in the breast with human MDA-MB-468LN cells and treated with either standard or nanocarrier-conjugated combination therapy (doxorubicin +cisplatin) at 50% or 75% MTD, and monitored for efficacy and toxicity over 12-weeks.Results—Efficacy results for mice treated with HA-conjugated doxorubicin/cisplatin at 50% MTD include:[complete responses(CR)=5, partial responses(PR)=2, and stable disease(SD)=1]and for HA-conjugated dox/cis at 75% MTD:[CR=7,PR=1; all CR’s confirmed histologically]. In comparison, mice given standard dox/cis(50% MTD)demonstrated:[progressive disease(PD)=6, SD=1, and PR=1] and for standard dox/cis(75% MTD):[PD=5,SD=3; p<0.0001 on multivariate ANOVA]. At 75% MTD, standard drug-treated mice had significant weight loss compared to nanocarrier drug-treated mice(p<0.001).Conclusion—Subcutaneous nanocarrier-delivery of doxorubicin and cisplatin demonstrated significantly improved efficacy with decreased toxicity compared to standard agent combination therapy at all doses tested achieving complete pathologic tumor response. | en_US |
