[A long-term survival case of metastatic breast cancer treated with trastuzumab and paclitaxel].

We report a long-term survival case of metastatic breast cancer treated with trastuzumab and paclitaxel. The patient was a 50-year-old female. She underwent left mastectomy with axillary lymphadenectomy for advanced breast cancer with liver metastases. Histological examination showed papillotublar carcinoma, f, T3, ly3, v2, N2 (24/34), histological grade III, ER (-), PgR (-), HER2 (3+). Trastuzumab and paclitaxel was performed. One year after the operation, any lesions of liver were not detected by CT and she was diagnosed as a complete response. No evidence of viable lesions has been found for 7 years. Breast cancer with liver metastases often could be a life threatening, and therefore an optimal chemotherapy should be applied as soon as possible. Trastuzumab and paclitaxel would be one of the optimal chemotherapies for HER2 positive breast cancer.
