Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Stereotactic body radiation therapy may be able to deliver x-rays directly to the tumor and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well stereotactic body radiation therapy works in treating patients with inoperable stage I or stage II non-small cell lung cancer.

- timeFrame
- From the start of treatment to 2 years
- description
- Local control is defined as absence of local failure, which is defined as the combination of primary tumor failure (PTF) or involved lobe failure (ILF). PTF was defined based on meeting two criteria: 1. Local enlargement defined as ≥ 20% increase in the longest diameter of the gross tumor volume (GTV) per computerized tomography (CT), and 2. Evidence of tumor viability. Tumor viability could be affirmed by either demonstrating positron emission tomography (PET) imaging with uptake of a similar intensity as the pretreatment staging PET, or by repeat biopsy confirming carcinoma. PTF included marginal failures occurring within 1 cm of the planning target volume (PTV). ILF is defined as failure beyond the primary tumor but within the involved lobe. Local control time is defined as time from start of treatment to the the date of local recurrence, last known follow-up (censored), or death without local failure (censored). Rates are estimated using the Kaplan-Meier method.

* T3 (≤ 5 cm), N0, M0 (chest wall primary tumors only)
* No primary tumor of any T-stage within or touching the zone of the proximal bronchial tree\* NOTE: \*Defined as a volume 2 cm in all directions around the proximal bronchial tree (carina, right and left main bronchi, right and left upper lobe bronchi, intermedius bronchus, right middle lobe bronchus, lingular bronchus, and right and left lower lobe bronchi)
* No primary T3 tumors involving the central chest (≤ 2 cm toward carina invasion) or structures of the mediastinum
* Any hilar or mediastinal lymph nodes \> 1 cm on CT scan OR demonstrating suspicious uptake on positron-emission tomography scan must be biopsied and confirmed negative for NSCLC
* The primary tumor must be deemed technically resectable with a reasonable possibility of obtaining a gross total resection with negative margins (defined as a potentially curative resection (PCR))
