Background: The use of anthracyclines in metastatic breast cancer (MBC) is limited by cumulative dose-dependent cardiotoxicity mostly in elderly women with comorbidities. 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. Methods: 84 elderly women >70 years of age (median age 78 years) with MBC HER2 negative were enrolled. Performance Status in 58 patients was ECOG-0 and in 26 patients was ECOG-1. Results: 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). Hematologic toxicity with neutropenia was the most frequent adverse event, but the treatment was well tolerated maintained a manageable cardiotoxicity. Conclusion: 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.

Abstract

Background: The use of anthracyclines in metastatic breast cancer (MBC) is limited by cumulative dose-dependent cardiotoxicity mostly in elderly women with comorbidities. 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. Methods: 84 elderly women >70 years of age (median age 78 years) with MBC HER2 negative were enrolled. Performance Status in 58 patients was ECOG-0 and in 26 patients was ECOG-1. Results: 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). Hematologic toxicity with neutropenia was the most frequent adverse event, but the treatment was well tolerated maintained a manageable cardiotoxicity. Conclusion: 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.
