Study start date: May 1, 2004

Actual date on which the first participant was enrolled.

OBJECTIVES: Primary * Determine whether treatment with stereotactic body radiotherapy results in acceptable local control (i.e., ≥ 80%) in patients with medically inoperable stage I or II non-small cell lung cancer. Secondary * Determine treatment-related toxicity in patients treated with this therapy. * Determine disease-free survival, overall survival, and patterns of failure in patients treated with this therapy. OUTLINE: This is a multicenter study. Patients receive 3 fractions of stereotactic body radiotherapy over 8-14 days in the absence of disease progression or unacceptable toxicity. Patients are followed up at 6 and 12 weeks, every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 52 patients will be accrued for this study within 26 months.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

59 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
