Thoracoscopy in Patients With Stage IIIA Non-Small Cell Lung Cancer
RATIONALE: Diagnostic procedures such as thoracoscopy may help to measure a patient's response to previous treatment.
PURPOSE: Diagnostic trial to determine the accuracy of thoracoscopy in patients who have stage IIIA non-small cell lung cancer.

OUTLINE: The purpose of this study is to test the usefulness and safety of restaging the patient's cancer by a procedure called a thoracoscopy. Restaging is a process by which physicians measure the response of the patient to treatment. The primary and secondary objectives are described below.
1. Evaluate the feasibility of using videothoracoscopy to access and identify residual viable cancer in mediastinal lymph nodes and/or evaluate for other conditions which render patients unresectable (pleural carcinomatosis or T4 primary tumors) following prior mediastinoscopy and a period of neoadjuvant therapy for Stage IIIA N2 non-small cell lung cancer.
- Evaluate the safety (morbidity and mortality) of pre-resectional, thoracoscopic restaging of patients who have undergone prior mediastinoscopy and induction therapy for Stage III (N2) NSCLC.
- Assess the accuracy (false-negative rate) of thoracoscopic mediastinal node restaging after prior mediastinoscopy and induction therapy.
