Brief Summary:

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells.

PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy in treating patients with non-small cell lung cancer that cannot be surgically removed.

Condition or disease Intervention/treatment Phase
Lung Cancer Radiation: radiation therapy Phase 1 Phase 2

Detailed Description:

OBJECTIVES: I. Assess the treatment related morbidity associated with escalating doses of 3-dimensional conformal radiotherapy (3D-CRT) in patients with locally advanced, inoperable, non-small cell lung cancer. II. Determine the maximum tolerated dose of 3D-CRT in these patients. III. Evaluate the morbidity associated with high dose 3D-CRT for carcinoma of the lung.

OUTLINE: This is a dose escalation study. Patients are stratified by the percentage of total lung volume (TLV) receiving greater than 20 Gy of radiation (less than 25% vs 25% to less than 37% vs at least 37%). As of 7/1/1999, the third stratum closed to accrual. Patients receive 3-dimensional conformal radiotherapy (3D-CRT) 5 days a week for either 6-7 weeks, 7-8 weeks, or 9-10 weeks (depending on the cohort). Within each TLV stratum, cohorts of 15-36 patients receive escalating doses of 3D-CRT until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which less than 15% of patients experience dose limiting toxicity. Patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 15-36 patients per cohort will be accrued for this study within 1 year. As of 7/1/1999, the third stratum closed to accrual.
