Abstract | BACKGROUND: PATIENTS AND METHODS: Treatment included low doses of 180 mg/m2 nab-paclitaxel that were administered on day 1 of each 3-week cycle to 35 patients. The primary endpoint was the completion rate of six cycles of treatment. RESULTS: A total of 35 eligible patients were enrolled and received a median of eight (range 2-24) cycles of low-dose nab-paclitaxel therapy. The completion rate of six cycles of treatment was 66%. ORR and clinical benefit rate was 23 and 71%, respectively. Median PFS was 6.5 months and median OS was 44 months. Adverse events were relatively mild. Commonly observed grade 3/4 adverse events were neutropenia (46%), leukopenia (9%), and hypertension (3%). No grade 3-4 peripheral sensory neuropathy occurred. CONCLUSION: Treatment with a low dose of nab-paclitaxel once every 3 weeks was tolerable and of acceptable safety and might be beneficial for patients with metastatic or recurrent breast cancer.
