Abstract
BACKGROUND
The aim of the study was to assess the toxicity profile, activity in terms of response rate, time to progression, overall survival, and quality of life of pegylated liposomal doxorubicin (PLD) and gemcitabine combination in chemo-naïve and pretreated metastatic breast cancer (MBC) women.
METHODS
Patients were eligible if they had disease progression to prior chemotherapy (anthracycline-including or not) for early breast cancer or MBC. Patients received PLD 25 mg/m(2) intravenously on day 1 plus gemcitabine 800 mg/m(2) intravenously on days 1 and 8 of each 21-day cycle.
RESULTS
Of 50 patients enrolled, 37 had received prior adjuvant chemotherapy (24 with an anthracycline) and 23 prior chemotherapy for metastatic disease (6 with an anthracycline). Two complete responses and 20 partial responses were achieved in 46 assessable patients (overall response rate: 47.8%). Responses were observed in 14 (46.6%) of 30 patients with previous anthracycline exposure. Median response duration was 7 months, median duration of clinical benefit 8 months, time to progression 7 months. At a median follow-up of 10 months, 79.4% patients were alive at 1 year. No neutropenic complication was observed. Non-hematological toxicities were mild. One patient previously treated with an anthracycline developed a transient decrease (26%) in the left ventricular ejection fraction, with cardiac function recovering within 6 months.
CONCLUSION
Because of the non-overlapping toxicity profiles of both PLD and gemcitabine, this combination can be regarded as a reliable therapeutic option for patients who have failed previous treatments, including anthracycline, for MBC.
