Study Summary
RATIONALE: 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. PURPOSE: This phase II trial is studying how well conformal radiation therapy works in treating patients with metastatic cancer outside the brain.
Primary Outcome
Local control (e.g. absence of local progression) is defined as Complete response (CR), partial response (PR) or stable disease (SD) of the treated site(s). Complete response is the disappearance of the target lesion. Partial response is a \>/= 50% decrease in maximal dimension compared to pretreatment imaging. Stable disease does not qualify for CR, PR, or progression.Progression is an interval increase in the maximal dimension of the target lesion.
Interventions
- OTHER questionnaire administration
- RADIATION hypofractionated radiation therapy
- RADIATION image-guided radiation therapy
- RADIATION 3-dimensional conformal radiation therapy
- RADIATION tomotherapy
