OBJECTIVES: Primary * Compare overall survival of patients with selected stage IIIB or stage IV non-small cell lung cancer treated with concurrent vs sequential paclitaxel, carboplatin, and cetuximab. Secondary * Compare response rates (confirmed and unconfirmed, complete and partial) in patients treated with these regimens. * Compare the toxic effects of these regimens in these patients. * Correlate epidermal growth factor receptor polymorphisms and downstream biomarkers with response to cetuximab in these patients. OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms. * Arm I (concurrent cetuximab): Patients receive cetuximab IV over 1 hour (over 2 hours on day 1 of course 1 only) on days 1, 8, and 15 and paclitaxel IV over 3 hours and carboplatin IV over 30 minutes on day 8. Treatment repeats every 21 days for a total of 4 courses (12 weeks) in the absence of disease progression or unacceptable toxicity. Beginning on week 13, patients receive single-agent cetuximab IV over 1 hour once weekly in the absence of disease progression or unacceptable toxicity. * Arm II (sequential cetuximab): Patients receive paclitaxel IV over 3 hours and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for a total of 4 courses (12 weeks) in the absence of disease progression or unacceptable toxicity. Beginning on week 13, patients receive single-agent cetuximab IV over 1 hour (over 2 hours on week 13 only) once weekly in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months for 1 year and then every 6 months for 2 years. PROJECTED ACCRUAL: A total of 180 patients (90 per treatment arm) will be accrued for this study within 9 months.
