DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed non-small cell lung cancer

  • Stage IIIB (by pleural effusion only) or stage IV disease

  • No predominately squamous cell carcinoma

    • Mixed tumors will be categorized by predominant cell type

• Must have completed 4 courses of platinum-based, doublet chemotherapy and bevacizumab*, has no disease progression, and meets the following criteria:

  • Platinum agent may have included carboplatin or cisplatin

  • A change in the platinum doublet is acceptable provided the following are true:

    • Basis for change was toxicity rather than disease progression
    • Total number of courses of any platinum doublet plus bevacizumab was 4
  • At least 3 of 4 courses must have included bevacizumab NOTE: *Patients age 70 and over may have completed 4 courses of single-agent chemotherapy plus bevacizumab; single agent chemotherapy may have included paclitaxel, docetaxel, gemcitabine hydrochloride, vinorelbine ditartrate, or pemetrexed disodium
• No brain metastases by brain MRI or head CT scan
