A 73-year-old woman underwent chemotherapy, radiotherapy, and hormonal therapies for right advanced breast cancer (T4, N3, M1, Stage IV) in 1993. She obtained a complete response in pathological evaluation (pCR) in 1998. For adjuvant therapies, she had been treated with hormonal therapies for five years until 2003. After the interruption of hormonal therapies, the serum levels of tumor markers had been elevated, and she had a right axillary local recurrence and a right ovarian metastasis detected by a FDG-PET/CT in February 2006. The right axillary local recurrence lesion was then resected, and she has since been treated with hormonal therapy of aromatase inhibitor (AI). The serum levels of tumor markers have been remarkably reduced, and FDG-PET/CT has showed the disappearance of the right axillary local recurrence, and the decrease of FDG accumulation of the right ovarian metastases in February 2007. We present a case of non-operated advanced breast cancer with local recurrence surviving successfully long term when treated with AI.
