Procedure: neoadjuvant therapy
Procedure: quality-of-life assessment
Procedure: therapeutic conventional surgery
Procedure: thoracic surgical procedure

- Determine the positive threshold of lymph node radioactivity after fludeoxyglucose F 18, utilizing the gamma probe, in patients with resectable stage I or II non-small cell lung cancer.
- Compare the accuracy of detecting thoracic lymph node metastases using positron emission tomography-computed tomography (PET-CT) versus the intra-operative hand-held gamma probe in these patients.
- Determine the ability of the gamma probe to detect lymph node micrometastases, resulting in upstaging in these patients.
- Assess the clinical relevance of the gamma probe-detected lymph node metastases by measuring patient survival, tumor recurrence, impact on patient quality of life, and cost.
OUTLINE: Patients undergo a positron emission tomography-computed tomography (PET-CT) scan within 90 days before surgery. Beginning 1-4 hours before surgery on day 1, patients receive an injection of fludeoxyglucose F 18 (FDG) and a mediastinoscopy is performed. FDG-avid lymph nodes are obtained and may undergo immunohistochemical analysis or standard analysis. Patients with mediastinal lymph node micrometastasis do not undergo primary tumor resection. Patients with ipsilateral mediastinal micrometastases undergo neoadjuvant chemotherapy prior to surgical resection. Patients with contralateral mediastinal micrometastases undergo definitive chemoradiotherapy. In the absence of mediastinal lymph node metastases (micro or macro), complete surgical resection is performed after the mediastinoscopy, including complete thoracic lymphadenectomy. The tumor and lymph nodes (both from mediastinoscopy and thoracotomy) undergo radioactivity measurements with the hand-held gamma probe. Fresh tumor and lymph node samples are stored for future studies.
Patients complete the Short Form 36 Health Survey (SF-36) before surgery and at 1, 3, and 6 months after surgery to assess the potential impact of the gamma probe on patient quality of life.
After completion of study, patients are followed every 6 months for 2 years, and then annually for 3 years.
