Abstract

Doxorubicin is highly effective and widely used in breast cancer; however, its use is limited by cardiotoxicity related to its cumulative dose. In previous studies, pegylated liposomal doxorubicin (PLD) has shown an acceptable toxicity profile with minimal cardiotoxicity. Between June 2006 and October 2009, 27 metastatic breast cancer patients were treated with first-line PLD and vinorelbine at the University of Florence, Radiotherapy Unit. PLD (30 mg/m 2) was administered on day 1, and oral vinorelbine (60 mg/m 2) was administered on days 1 and 8 of a 4-week cycle. All patients were previously treated with anthracycline-based adjuvant chemotherapy. Median age was 52 years (range 38-69) and median time to metastasis was 78.5 months. There were no treatment interruptions or discontinuation for cardiac toxicity and no treatment-related deaths. Grade 3 hematological toxicity was observed in 18.6% of patients, and 3.7% had grade 3 non-hematological adverse events. With a median follow-up of 13.2 months (range 3-33), median response duration was 6.1 months, and median PFS was 5.3 months. The overall clinical benefit rate was 55.5%. Our experience adds to evidence supporting the activity and cardiac safety of PLD and vinorelbine in metastatic breast cancer patients previously treated with anthracycline-based adjuvant chemotherapy.
