J Coll Physicians Surg Pak Jan ;15(4):200-3.

Objective: To evaluate the efficacy and toxicity of 1-hour weekly Paclitaxel in metastatic breast cancer along with evaluation of overall survival. Design: A phase II interventional trial. Place and Duration of Study: Oncology Department, Combined Military Hospital, Rawalpindi, between August 2001 to July 2003. Patients and Methods: Thirtysix patients were enrolled in the study. All patients with histologically confirmed and bidimensionally measurable metastatic breast cancer who had received previously either chemotherapy or hormone therapy were included in the study. Paclitaxel was administered in 1-hour weekly infusion in a dose of 100mg/m2 for 12 doses. Results: All patients had received previous chemotherapy with either CAF or CMF. Twentyfive patients had also received hormone therapy, 61% had two or more metastatic sites involved, and lung was the common site of involvement. Complete response was observed in 4 (11.1%) patients, partial response in 14 (38.8%) patients, with an overall response rate of 50.0%. Clinical benefit was 94.4% and median overall survival was 11 months. Treatment was well-tolerated with no grade 3 or 4 toxicity. Common side effects were arthralgias, myalgias and neutropenia. Conclusion: Treatment with 1-hour weekly infusion of Paclitaxel is a well-tolerated chemotherapy with a substantial degree of efficacy in patients with metastatic breast cancer.
