Study of a New Device to Control Breathing Movement During Radiotherapy for Lung Cancer

What this Trial Is About

Researchers are studying the safety and effectiveness of abdominal pressure devices to reduce respiratory movement in patients with non-small cell lung cancer. The main goal is to determine if these devices can limit tumor movement during breathing in patients undergoing stereotactic radiotherapy. This observational study is led by Tianjin Medical University Cancer Institute and Hospital and focuses on lung cancer patients suitable for this targeted treatment. Participants will be grouped based on whether they use breathing management with abdominal compression or have no breathing management. The study involves two types of scans CT4DCT scans with and without breathing management. The abdominal compression device is applied to suppress respiratory movement to help control tumor motion during treatment. During the study, participants will record how much they use the abdominal pressure devices. Researchers will monitor tumor displacement range within six months after enrollment using imaging scans. This helps assess how well the device controls tumor movement. The study lasts up to six months, focusing on safety, effectiveness, and patient adherence to using the device during radiotherapy.
