A Phase II Trial Of Fractionated Vinorelbine/Doxorubicin As First-line Therapy For Advanced Breast Cancer

Very promising results have been obtained by combining vinorelbine and doxorubicin, two of the most active drugs in metastatic breast cancer. However, despite the activity reported, this combination has shown a 10% rate of grade 2–4 cardiac toxicity, mainly due to the total cumulative doses of anthracycline delivered. The aim of this study was to divide the total dose of doxorubicin into two administrations on days 1 and 8, in order to cut down its toxicity while maintaining the same activity. Fifty-two chemotherapy naive patients with metastatic breast cancer entered into the study and were treated with vinorelbine 25 mg/m2 plus doxorubicin 25 mg/m2 both on days 1 and 8 every three weeks. Fifty-one patients were eligible and evaluable for toxicity while 47 of them were evaluable for activity. Haematological toxicity was predominantly related to neutropenia, with grade 3/4 in 16% of cycles. Non-haematological toxicity ...
