title: [Complete response of advanced breast cancer with lymph node metastases to nab-paclitaxel therapy-report of a case].
abstract: We report a case of breast cancer with lymph node metastases. A complete response was recognized in response to nab-paclitaxel as a first-line therapy after recurrence. The patient was a 50-year-old woman who had a tumor in her right breast. We palpated a mass with clear boundaries in her right breast. The tumor was 2 cm in diameter. Core-needle biopsy of the breast tumor led to a diagnosis of invasive ductal carcinoma (estrogen receptor-, progesterone receptor-, and human epidermal growth factor receptor 2-negative). She received 4 cycles of EC (E: 90 mg/m2/tri-weekly; C: 600 mg/m2 /tri-weekly) plus 4 cycles of TC(T: 75 mg/m2/tri-weekly; C: 600 mg/m2/tri-weekly)as preoperative adjuvant chemotherapy. After chemotherapy, she underwent quadrantectomy plus axillary lymph node dissection. Six months after the operation, lymph node metastases were observed in her right supraclavicular lymph nodes. She received 8 cycles of nab-paclitaxel(260 mg/m2/tri-weekly) therapy. After 8 cycles of treatment, ultrasonography and computed tomography revealed the disappearance of the metastatic lymph nodes. Therefore, a clinical complete response was observed.
