Adjuvant Cetuximab and Chemoradiotherapy Using Either Cisplatin or Docetaxel in Treating Patients With Resected Stage III or Stage IV Squamous Cell Carcinoma or Lymphoepithelioma of the Head and Neck

OBJECTIVES:

Primary

• Compare disease-free survival of patients with resected stage III or IV squamous cell carcinoma or lymphoepithelioma of the head and neck treated with adjuvant cetuximab in combination with chemoradiotherapy comprising docetaxel vs cisplatin.

Secondary

• Compare the safety and efficacy of these regimens in these patients.
• Compare locoregional control and overall survival rates in patients treated with these regimens.
• Correlate epidermal growth factor receptor (total and phosphorylated), pMAPK, pAKT, Stat-3, Ki-67, cyclo-oxygenase-2, and cyclin B1 expression with outcome in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to Zubrod performance status (0 vs 1), risk category (positive margins vs high risk [i.e., ≥ 2 positive nodes or extracapsular nodal extension]) and use of intensity-modulated radiotherapy (no vs yes). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive cetuximab IV over 2 hours on day 1 (week 1). Patients then receive cetuximab IV over 1 hour and cisplatin IV over 1 hour before radiotherapy on days 8, 15, 22, 29, 36, and 43 (weeks 2-7). Patients undergo radiotherapy once daily, 5 days a week, beginning on day 8 for a total of 6 weeks (weeks 2-7).
• Arm II: Patients receive cetuximab and undergo radiotherapy as in arm I. Patients also receive docetaxel IV over 30 minutes before radiotherapy on days 8, 15, 22, 29, 36, and 43 (weeks 2-7).

Treatment in both arms continues in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years and then every 6 months for 4 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 230 patients (115 per treatment arm) will be accrued for this study within approximately 29 months.

DISEASE CHARACTERISTICS:

• Histologically confirmed squamous cell carcinoma of the head and neck meeting the following criteria:

• Site of tumor origin in the oral cavity, oropharynx, larynx, or hypopharynx (excluding lip, nasopharynx, or sinuses)
• Gross total resection must be completed within 7 weeks of randomization, with pathology demonstrating one or more of the following risk factors:

• Histologic extracapsular nodal extension
