Polyglutamate Paclitaxel Plus Carboplatin Compared With Paclitaxel Plus Carboplatin in Treating Patients With Advanced or Recurrent Non-Small Cell Lung Cancer

DISEASE CHARACTERISTICS:

Histologically or cytologically confirmed non-small cell lung cancer (NSCLC) meeting 1 of the following criteria:

Locally advanced or recurrent disease previously treated with radiotherapy and/or surgery
Stage IIIB and not a candidate for combined modality therapy
Stage IV
No evidence of small cell carcinoma, carcinoid, or mixed small cell/non-small cell histology

Cytological diagnosis must be based on the following:

No cellular diagnosis by sputum cytology alone
Cytologic specimens obtained from brushings, washings, or needle aspiration of a defined lesion or pleural effusion are acceptable
Measurable or nonmeasurable disease

Brain metastases allowed provided patient received prior standard antitumor therapy for CNS metastases (e.g., whole brain radiotherapy, stereotactic radioablation, or surgery) and the following conditions are met:

Neurologic function stable for at least 2 weeks before study entry
Off steroid therapy or on a tapering regimen
Recovered from prior therapy
