[Efficacy of weekly docetaxel therapy for advanced or recurrent breast cancer]

To evaluate the safety and efficacy of weekly docetaxel (weekly TXT) in cases of advanced or recurrent breast cancer, 31 patients were enrolled in this pilot study of weekly TXT given at 25 mg/m2/w. Each cycle consisted of 3 weeks of therapy followed by a 1-week treatment break in an outpatient setting. Patients received a median of 15 infusions with a median cumulative dose of 680 mg. The median time to treatment failure was 8 months. The overall response rate was 32.3%, and 22.6% of patients had stable disease for at least 6 months. The response rate was consistent regardless of prior chemotherapy with anthracycline. There was no grade 3 or 4 toxicity, and the regimen was generally well tolerated. Although 37.5% of patients had grade 1 or 2 nail change, myelosuppression, fatigue, nausea, vomiting and fluid retention were mild. Weekly TXT seems to be an effective and feasible treatment for advanced or recurrent breast cancer patients.
