AMSA and peptichemio in the treatment of advances metastatic breast cancer: a phase II study.

A combination of AMSA and peptichemio was evaluated in patients with advanced breast cancer refractory to conventional chemotherapy. Of 33 evaluable patients, five patients (15%) achieved partial remission, two patients (6%) had less-than-partial remission, nine patients (27%) had stable disease, and seventeen patients (52%) had progressive disease. The median duration of response was 6 months (range: 3-8 months). The median duration of stable disease was 5 months (range: 2-7 months). Myelosuppression was the dose-limiting toxicity. This combination of AMSA and peptichemio did not result in an improved response rate or duration of remission compared to the previous experience with single-agent therapy with either of these agents.
