Genetic Changes in Patients With Non-Small Cell Lung Cancer Who Are Receiving Vinorelbine and Gemcitabine Before Surgery

DISEASE CHARACTERISTICS:

• Histologically confirmed non-small cell carcinoma of the lung
• May be confirmed at the initial bronchoscopy and mediastinoscopy
• Stage IB (T2, N0, M0)
• Stage IIA (T1, N1, M0)
• Stage IIB (T2-3, N0-1, M0)
• Stage IIIA (T1-3, N1-2, M0)
• stage IIIB (2 lesions in 1 lobe [T4])
• No N3 lymph nodes (contralateral mediastinal/hilar and supraclavicular/scaline) OR T4 primary tumor (malignant pleural effusion or mediastinal invasion) by clinical staging criteria (seen on CT or PET scan and proven by mediastinoscopy)
• No metastatic disease (except N1 or N2 disease) or malignant pleural effusion* detected on preoperative evaluation
• No exudative effusions (even if cytologically negative)
• Pleural fluid is considered exudative if the following apply:
• Ratio of pleural fluid protein to serum protein is greater than 0.5
• Ratio of pleural fluid lactic dehydrogenase (LDH) to serum LDH is at least 0.6
• Pleural fluid LDH is greater than 200 IU/L
• No multiple areas of fluorodeoxyglucose (FDG) uptake** outside the area of the primary tumor in the lung NOTE: *Effusions visible only on CT scan and not large enough for safe thoracentesis are allowed

NOTE: **If only 1 area shows an increase in FDG uptake, the area of concern requires further evaluation (e.g., biopsy) to exclude metastatic disease

• Bidimensionally measurable or evaluable disease* NOTE: *Lesions apparent on chest CT scan (e.g., ill-defined masses associated with post obstructive changes and mediastinal or hilar adenopathy measurable in 1 dimension) are considered evaluable
