Stereotactic Radiosurgery in Treating Patients With Stage I or Stage II Non-Small Cell Lung Cancer
Feasibility and Outcome of Cyberknife® Precision Hypofractionated Radiosurgery for the Curative Management of Non-Small Cell Lung Cancer
RATIONALE: Stereotactic radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue.
PURPOSE: This phase I trial is studying the side effects and best dose of stereotactic radiosurgery in treating patients with stage I or stage II non-small cell lung cancer.

OBJECTIVES:
- To establish the maximum tolerated dose of CyberKnife® hypofractionated stereotactic radiosurgery in patients with medically inoperable, stage I or II non-small cell lung cancer.
- To establish the relationship between positron emission tomography (PET) response and local control and survival using fludeoxyglucose F 18 PET/CT imaging before treatment and at 1, 3, 6, and 12 months after treatment.
OUTLINE: Patients undergo placement of 3 gold fiducial markers by CT-guidance or bronchoscopy. Patients then undergo CyberKnife® hypofractionated stereotactic radiosurgery over 45-120 minutes twice weekly for 2 weeks.
Patients undergo fludeoxyglucose F 18 PET/CT scan at baseline and at 1, 3, 6, and 12 months after completion of treatment.
After completion of study treatment, patients are followed periodically for up to 4 years.

Beschrijving
Inclusion Criteria:
DISEASE CHARACTERISTICS:
Histologically confirmed non-small cell lung cancer
Stage I or II disease (T1-3, N0, M0)
- T2 or T3 tumor ≤ 5 cm
- No T3 tumors involving the central chest or mediastinum (only chest wall involvement allowed)
Tumor deemed technically resectable, in the opinion of an experienced thoracic surgeon, AND patient deemed "medically inoperable"
- Patients with fluorodeoxyglucose (FDG)-avidity in mediastinal lymph nodes are eligible provided they are able to undergo mediastinoscopy to confirm N0 status
PATIENT CHARACTERISTICS:
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Not pregnant or nursing
- Fertile patients must use effective contraception during and for ≥ 6 months after completion of study treatment
Exclusion Criteria:
- No history of contrast allergy
- No psychological issues that would preclude the completion of study treatment
PRIOR CONCURRENT THERAPY:
- No prior radiotherapy or chemotherapy
- No suspected nodal metastasis that cannot be falsified by mediastinoscopy (i.e., hilar or mediastinal nodes that are either fludeoxyglucose F 18 [FDG]-avid or measure > 1 cm in short axis diameter on CT scan)
- No tumor within or touching the proximal bronchial tree, defined as a volume of 2 cm in all directions around the proximal bronchial tree (carina, right and left main stem bronchi, right and left upper lobe bronchi, bronchus intermedius, right middle lobe bronchus, lingular bronchus, right and left lower lobe bronchi)
