Abstract

BACKGROUND.

Previous data from an institutional pilot study in patients with advanced or recurrent squamous cell carcinoma of the head and neck (SCCHN) who received treated a combined chemotherapy regimen of paclitaxel, cisplatin, and 5-fluorouracil indicated an overall response rate of 60% and a median survival of 6 months. To validate these results and to determine the feasibility of this combination, a Phase II study was conducted by the Southwest Oncology Group (SWOG S0007).

METHODS.

Patients with advanced or recurrent SCCHN were eligible if they had received 1 previous regimen of induction/adjuvant chemotherapy or no prior systemic therapy. Patients received treatment with paclitaxel (135 mg/m2 on Day 1), followed by cisplatin (75 mg/m2 on Day 1), and 5-fluorouracil (1000 mg/m2per day as a 96-hour continuous infusion on Days 1–4) every 21 days.

RESULTS.

Seventy-six patients received a combined total of 286 cycles of chemotherapy. Sixty-nine patients were evaluable for response. There were 5 complete responses (7%) and 23 partial responses (33%) partial responses, for an overall response rate of 41%. The median progression-free survival was 4 months, and the median overall survival was 10 months. Six treatment-related deaths were documented, including deaths in 2 patients who had a Zubrod PS of 2. Grade 3 or 4 neutropenia (according to National Cancer Institute Common Toxicity Criteria [version 2.0]) was observed in 47% of patients. Other Grade 3 or 4 adverse events included mucositis (34% of patients), nausea (20% of patients), anemia (9% of patients), and neuropathy (8% of patients).

CONCLUSIONS.

The combination of paclitaxel, cisplatin, and 5-fluorouracil had efficacy similar to that of standard treatment regimens in patients with advanced or recurrent SCCHN but with increased toxicity. Cancer 2006. © 2006 American Cancer Society.
