Radiation Therapy Using 3-Dimensional Treatment Planning in Patients With Non-small Cell Lung Cancer

Phase 1
Completed
Conditions
Lung Cancer
Interventions
Radiation: radiation therapy
Registration Number
NCT00002484
Lead Sponsor
Memorial Sloan Kettering Cancer Center
Brief Summary

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.

Detailed Description

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.

Patients are followed at 1 month and then every 4 months thereafter.

PROJECTED ACCRUAL: A total of 60-70 patients will be accrued for this study within 3 years.
