DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed non-squamous, non-small cell lung cancer (NSCLC), including any of the following subtypes*:

  • Adenocarcinoma
  • Large cell
  • Bronchioloalveolar
  • NSCLC not otherwise specified NOTE: *Mixed tumors will be categorized by the predominant cell type unless small cell or squamous cell elements are present, in which case the patient is ineligible

• Advanced disease, as defined by any of the following:

  • Stage IV (M1a or M1b)* disease based on the TNM staging system
  • Recurrent disease after prior radiotherapy or surgery NOTE: *In the current revision of the AJCC staging system (v7, 2009), former stage IIIB with malignant pleural effusion will now be classified as Stage IV (M1a).

• Measurable disease, as defined by RECIST (PET and the PET portion of PET/CT are not acceptable methods of evaluation for response)

  • No prior radiotherapy to the only area of measurable disease unless there is progression of disease documented by physical examination, imaging tests, or pathology in this region

• Brain metastases are allowed, provided they have been treated with surgery and/or radiotherapy, the patient is neurologically stable, and repeat brain imaging shows no progression in the brain

  • Patients must undergo head CT scan or MRI within 4 weeks prior to randomization for evaluation
  • At least 6 weeks since prior craniotomy and ≥ 4 weeks since prior radiotherapy
