Study Summary

We will conduct a prospective clinical study involving up to 40 non-Small Cell Lung Cancer (nSCLC) patients to determine dose thresholds for central and peripheral BSS elements. All imaging will be performed under motion control (e.g., with or without abdominal compression) defined as breathing with a resultant motion ≤5mm by fluoroscopy. In this study, a high-resolution breath-hold CT scan (BHCT) will be acquired from each patient immediately before or after the 4DCT scan. A follow-up high resolution BHCT (also under motion control) will be acquired from each patient 8-12 months post-SabR, and BSS elements will be segmented in LungPointRT. A radiation oncologist will compare the pre- and post-SabR contours to determine segmental collapse.

Primary Outcome

Evaluating the association between radiation-induced collapse of Branching Serial Structures (BSS) elements, characterized by segmental collapse, and localized change in pulmonary function. a map of collapsed and open BSS elements will be generated from the contoured BSS trees in the pre- and post-SAbR BHCT scans to determine the impact of radiation-induced collapse of BSS elements and localized changes to pulmonary function.
