THE EFFICACY OF PACLITAXEL REGIMEN FOR RECURRENT OR METASTATIC IN BREAST CANCER
Main Article Content
Abstract
Objectives: Describe the clinical and paraclinical characteristics of metastatic breast cancer patients and evaluate the efficacy of paclitaxel regimen for recurrent or metastatic in breast cancer. Patients and methods: Retrospective, descriptive study on 39 patients with recurrent or metastatic of breast cancer, were treated with paclitaxel chemotherapy regimen at National Cancer Hospital. Results: The mean age was 56,8 ±9,8. In 32 patients of recurrent, mean time to first recurrence was 39 months. The overall response rate (ORR) of the regimen was 33,3 %. The complete response rate was 5,1%, the partial response rate was 28,2%, 46,2% of the patients were stable. ORR in first-line therapy was better than that in the second-line of treatment (ORR: 40,7% vs 25%; p=0,031). The median progression-free survival was 5,6 ± 0,3 months. The common toxicity was neutropenia (33,5%), anemia (38,6%), 10,3% for thrombocytopenia, hair loss (38,5%), and 51,3% for neurotoxicity. Conclusion: Paclitaxel regimen chemotherapy is effective in high response rates and progression-free survival for patients with recurrent or metastatic of breast cancer. It is well tolerated by patients. Therefore, it can be widely applied in clinical practice.
