The aim of this observational retrospective study was to evaluate the efficacy of non-pegylated liposomal doxorubicin (Myocet®) and cyclophosphamide in elderly women as HER2 negative first-line MBC treatment....The drug was well tolerated, with overall response rates were >40%, median overall survival was 16.2 months (95%CI:14.6-18.8) and median progression free survival was 5.8 months (95%CI:4.4-8.6)....Non-pegylated liposomal doxorubicin may represent a valid therapeutic option in first-line for elderly patients with HER/2 negative MBC improving survival, anti-tumor response rate and de-creases cardiotoxicity.
