NCT03422302

Brief Summary

This pilot phase I/II trial studies how well a continuous positive airway pressure device or deep inspiration breath hold works in reducing tumor movement in patients undergoing stereotactic body radiation therapy (SBRT) for lung cancer. The continuous positive airway pressure device works by blowing air into the lungs while patients wear a face mask or nozzle to help expand their airways and lungs. Deep inspiration breath hold is a standard technique that uses active breath-holding to restrict movement of the body. Using a continuous positive airway pressure device may work better than deep inspiration breath hold in lowering the amount of tumor movement during stereotactic radiation body therapy.

Outcome Measures

Primary Outcomes (1)

  • Estimation of decrease in tumor motion

    Paired t-test will be used to compare continuous positive airway pressure (CPAP) to deep inspiration breath hold (DIBH) in the decrease of tumor motion from free breathing. Linear regression may be used to evaluate the difference between CPAP and DIBH in the decrease of tumor motion from free breathing with the adjustment of important demographic and clinical variables in the model.

    Up to 10 days

Secondary Outcomes (2)

  • Increase in lung volume

    Up to 10 days

  • Assessment of time to deliver the planned radiation dose by using the most appropriate method

    Up to 10 days

Study Arms (1)

Treatment (CT simulation, CPAP, DIBH, SBRT, BiPAP)

EXPERIMENTAL

Patients undergo free-breathing, DIBH, and CPAP CT simulation scans. If patient has difficulty exhaling on CPAP, then patient undergo BiPAP CT simulation. The attending physician then compares all 3 simulation treatment plans (free-breathing, DIBH, and CPAP/BiPAP) and determines which method to use during SBRT. If CPAP/BiPAP is chosen as preferred method, patients wear CPAP/BiPAP over 1 hour prior to SBRT, then again during SBRT over 30-60 minutes. All other patients complete free-breathing or DIBH during SBRT over 30-60 minutes.
