[A complete response following treatment with Paclitaxel and bevacizumab for metastatic breast cancer].

A 60-year-old woman with left breast cancer underwent partial mastectomy and sentinel lymph node biopsy. Pathological examination revealed an invasive ductal carcinoma that was ER (+), PgR (-), HER2 (-), and node positive (1/1). She received adjuvant chemotherapy with doxorubicin and cyclophosphamide (AC), followed by weekly paclitaxel (PTX). After receiving radiation therapy, she was administered an aromatase inhibitor for 5 years. Six months after completion of therapy, she found a hard lymph node in the left infraclavicular area. Fine needle aspiration cytology of the lymph node indicated metastatic breast cancer. Fulvestrant was administered but disease progression was observed after 3 months. Systemic chemotherapy with PTX and bevacizumab (Bev) was begun. After 3 cycles of chemotherapy, computed tomography (CT) scan revealed a complete response (CR). After 6 cycles of chemotherapy, the CR has been maintained.
