Exclusion Criteria

• Patients with distant bone metastases at original diagnosis or relapse (patients with only skip lesions will be eligible)
• Patients with concurrent local and pulmonary recurrence at the time of enrollment; note: patients who had local recurrence previously that has been treated and now present with an isolated pulmonary recurrence and meet the surgical resection criteria stated above will be eligible
• Patients with primary refractory disease with progression of the primary tumor on initial therapy
• Patients with CNS disease or other sites of extra-pulmonary metastases at the time of most recent episode of disease recurrence preceding enrollment
