[A case of recurrent breast cancer successfully treated with docetaxel]

A 53-year-old female underwent mastectomy for left breast cancer in April, 1993. She was given oral tamoxifen but this had to be discontinued due to its side effects. In March, 1998, she developed bone and lung metastases, in spite of treatment with combination chemotherapy (CEF). We thus treated here with docetaxel 90 mg three times and 40 mg six times. After the chemotherapy, she achieved complete remissions of the lung metastases and a decrease in serum CEA, CA 15-3, NCC-ST439, and BCA225. Adverse reactions to docetaxel were grade 2 alopecia, grade 4 neutropenia, dysgeusia, and fluid retention. All were tolerable. This new agent may play an important future role in chemotherapy for recurrent breast cancer.
