Thoracoscopy in Patients With Stage IIIA Non-Small Cell Lung Cancer

Overview

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. OBJECTIVES: Primary Objective: 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. Secondary Objectives: 1. 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. 2. Assess the accuracy (false-negative rate) of thoracoscopic mediastinal node restaging after prior mediastinoscopy and induction therapy.
