[A case of recurrent breast cancer with life-threatening multiple lung metastasis markedly responding to CMF as third-line chemotherapy].

A 35-year-old woman with taxane and anthracycline-resistant recurrent breast cancer with multiple lung metastasis and carcinomatous lymphangitis was treated with CMF as third-line chemotherapy. A complete response was achieved,and the toxicities were tolerable. We thought that CMF could be a useful regimen as third-line chemotherapy for metastatic breast cancer.
