Phase III Comparison of High-Dose Paclitaxel + Cisplatin + Granulocyte Colony-Stimulating Factor Versus Low-Dose Paclitaxel + Cisplatin in Advanced Head and Neck Cancer: Eastern Cooperative Oncology Group Study E1393

PURPOSE: To determine dose-response effects and the activity of paclitaxel combined with cisplatin in patients with incurable squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: Two hundred ten patients with locally advanced, recurrent, or metastatic disease were randomly placed in either Arm A, paclitaxel 200 mg/m2 (24-hour infusion) + cisplatin 75mg/m2 + granulocyte colony-stimulating factor, or Arm B, paclitaxel 135 mg/m2 (24-hour infusion) + cisplatin 75 mg/m2. Cycles were repeated every 3 weeks until progression or a total of 12 cycles for complete responses. Primary outcomes were event-free and overall survival. RESULTS: No significant differences in outcomes were observed between the high- and low-dose paclitaxel regimens. The estimated median survival was 7.3 months (95% confidence interval, 6.0 to 8.6). The 1-year survival rate was 29%, and event-free survival was 4.0 months. The objective response rate (complete response plus partial response) was 35% for the high-dose patients a...
