Continuous Positive Airway Pressure Device or Deep Inspiration Breath Hold in Reducing Tumor Motion in Patients Undergoing Stereotactic Body Radiation Therapy for Lung Cancer
What this study is about
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.
View original scientific description
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.

- The patient is uncooperative.
- The patient has reduced consciousness.
- The patient has sustained trauma or burns to the face.
- The patient has undergone any facial, esophageal, gastric or sinus surgery within the last 3 months.
- The patient has idiopathic pulmonary fibrosis (IPF) as documented in their medical history.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
