简要总结
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Computer systems that allow doctors to create a 3-dimensional picture of the tumor in order to plan treatment may result in more effective radiation therapy.
PURPOSE: Phase I trial to study the effectiveness of high-dose radiation therapy planned using a 3-dimensional picture of the tumor in treating patients who have stage I, stage II, or stage III non-small cell lung cancer.
详细描述
OBJECTIVES:
- Determine the maximum dose of external beam irradiation deliverable using conformal 3-dimensional treatment planning in patients with non-small cell lung cancer.
- Determine the feasibility and efficacy of 3-dimensional treatment planning in delivering high doses of external beam radiotherapy to these patients.
- Determine whether computer-generated dose-volume histograms and normal tissue complication probability models can predict the degree of pulmonary toxicity resulting from external beam radiotherapy.
- Determine the relationship between dose of external beam radiotherapy and the degree of pulmonary function change.
OUTLINE: This is a dose escalation study.
Patients undergo 3-dimensional conformal external beam radiotherapy 5 days a week for 8-10 weeks.
Cohorts of 10 patients receive escalating doses of radiotherapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 20% of patients experience dose-limiting toxicity.
