RATIONALE: Radiation therapy may relieve symptoms in patients with non-small cell lung cancer. It is not yet known which regimen of radiation therapy is most effective in relieving symptoms in patients with non-small cell lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of radiation therapy to relieve symptoms in patients who have non-small cell lung cancer.

OBJECTIVES: I. Compare the efficacy of two schedules of radiotherapy in the palliation of symptoms in patients with non-small cell lung cancer. II. Compare the toxicity of these two regimens in these patients. III. Compare the quality of life and survival of patients treated with these two regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to center, weight loss in the previous 6 months (no greater than 10% vs greater than 10%), and performance status (ECOG 0 or 1 vs 2 or 3). Patients are randomized to undergo radiotherapy as 5 fractions over 5 days or 1 fraction on 1 day. Quality of life is assessed before treatment, weekly for 5 weeks, and monthly thereafter. Patients are followed weekly for 5 weeks, then every 2 months for 1 year.

PROJECTED ACCRUAL: A total of 210 patients will be accrued for this study.

• Fatigue
• Lung Cancer
• Nausea and Vomiting
• Pain
• Pulmonary Complications
• Quality of Life

• Procedure: fatigue assessment and management
• Procedure: nausea and vomiting therapy
• Procedure: pain therapy
• Procedure: quality-of-life assessment
• Radiation: radiation therapy
