OUTLINE: This is a multicenter study. Patients are stratified according to bevacizumab-appropriate status (yes vs no), smoking status (current or former [no smoking ≥ 1year] vs never [< 100 cigarettes lifetime]), and stage (M1a vs M1b). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive carboplatin IV over 30 minutes and paclitaxel IV over 3 hours with or without bevacizumab IV over 30-90 minutes on day 1. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 courses, patients receiving bevacizumab may continue to receive bevacizumab (as above) in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients receive carboplatin and paclitaxel with or without bevacizumab as in arm I. Patients also receive cetuximab IV over 1-2 hours on days 1, 8, and 15. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 courses, patients may continue to receive cetuximab with or without bevacizumab (as above) in the absence of disease progression or unacceptable toxicity.
Plasma and tissue samples are collected periodically for further laboratory analysis.
After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months for 2 years.

- Clinically significant peripheral vascular disease
- No known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies (e.g., trastuzumab [Herceptin®] or epoetin alpha)
- No other prior malignancy except for any of the following:
- Adequately treated basal cell or squamous cell skin cancer
- In situ cervical cancer
- Adequately treated stage I or II cancer from which the patient is currently in complete remission
- Any other cancer from which the patient has been disease-free for 5 years
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- Prior radiotherapy allowed provided patients have recovered from all associated toxicities at the time of study registration
