Combined Deep Inspiration Breath Hold (DIBH)-Expiration Planning Technique in Patients With Lung Tumors in Close Proximity to the Chest Wall

NCT04507828 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 4

Summary

The purpose of this study is to evaluate a new radiation planning and treatment delivery technique called Deep Inspiration Breath Hold (DIBH) and expiration technique. This technique will be used to treat patients who have tumors close to the chest wall and are candidates for Stereotactic Body Radiation Therapy (SBRT). This study will assess the reduction of radiation to the chest wall during treatment using this technique.

Treatment Planning using the DIBH Technique

Different radiation plans will be generated-one using a DIBH scan with corresponding target and normal tissue contour and a second using an expiration scan with corresponding target and normal tissue contours. The expiration scan can be an expiratory gating scan averaging the expiratory breathing phases or an expiration breath hold scan as determined based on patient performance during simulation and relative tumor displacement compared to the DIBH scan. Then a third plan will be generated conceptually combining the two previous plans, named the DIBH-expiration composite plan.
