Case Reports[A case of anthracycline- and taxane-resistant recurrent advanced breast cancer successfully treated with S-1 monotherapy].
We experienced a case of anthracycline- and taxane-resistant recurrent breast cancer with multiple liver metastases and multiple bone metastases showing marked improvement by S-1. A 52-year-old woman visited our hospital because of her liver dysfunction in May 2008. She underwent a partial mastectomy preserving chest muscles in another hospital in 2000, but further details were unknown. ⋯ Then the oral treatment with S-1 was started, and at the end of the second course, a significant reduction of abnormal accumulation in PET was noted. She has been quite well without any adverse effects from S-1. S-1 monotherapy was thus considered to be an effective treatment for advanced or recurrent breast cancer resistant to anthracyclines and taxanes.
