Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which regimen of stereotactic body radiation therapy is more effective in treating patients with non-small cell lung cancer.

PURPOSE: This randomized phase II trial is studying the side effects of two radiation therapy regimens and to see how well they work in treating patients with stage I non-small cell lung cancer.

Conditions

Interventions

RADIATION

Single-fraction stereotactic body radiation therapy (SBRT)

34 Gy in 1 fraction to the prescription line at the edge of the planning target volume (PTV). The maximum dose must exist within the PTV, and the prescription isodose surface must be ≥ 60% and \< 90% of the maximum dose. 99% of the PTV must receive a minimum of 90% of the prescription dose. The maximum dose to any point ≥ 2 cm away from the PTV in any direction must be at least \< 50% of the prescription dose. The percent of the lungs (excluding PTV) receiving 20 Gy or more must be \< 10%.

RADIATION

Multiple-fraction stereotactic body radiation therapy (SBRT)

48 Gy in four 12 Gy fractions to the prescription line at the edge of the planning target volume (PTV). Treatments are given on 4 consecutive calendar days, but at least 18 hours apart. The maximum dose must exist within the PTV, and the prescription isodose surface must be ≥ 60% and \< 90% of the maximum dose. 99% of the PTV must receive a minimum of 90% of the prescription dose. The maximum dose to any point ≥ 2 cm away from the PTV in any direction must be at least \< 50% of the prescription dose. The percent of the lungs (excluding PTV) receiving 20 Gy or more must be \< 10%.
