Trial Outcomes & Findings for Improving Pulmonary Function Following Radiation Therapy (NCT NCT02843568)
NCT ID: NCT02843568
Last Updated: 2024-10-10
Results Overview
The primary endpoint of this study will be the ratio of the tissue elasticity map following RT to the elasticity map before RT (i.e., the Jacobian ratio of (post RT /pre RT)) calculated from 4DCT at 3 months post-RT. Based on the randomness of our measurement technique, diminished expansion (i.e. substantial change) is defined as a Jacobian ratio \<0.94 (i.e., less than 94% of the pre-RT value).

Standard of Care
Subjects undergo four-dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning. Subjects undergo laboratory biomarker analysis, including spirometry, diffusion capacity (DLCO), and lung volumes (FEV, FEV1). Subjects complete a self-assessment, RTOG defined acute evaluation toxicity evaluation, RTOG late toxicity evaluation, and constitutional assessment.
Radiation doses between 60-66 Gy using standard fractionation (1.8-2.0 Gy/fx) and 40-60 Gy stereotactic body radiation therapy (SBRT) hypofractionation schemes are utilized. Treatment volumes are at the discretion of the treating radiation oncologist and should follow standard of care.
Laboratory Biomarker Analysis: Correlative studies
Standard fractionation: 60-66y Gy delivered in 1.8-2.0 Gy fractions over 30-36 treatments
Stereotactic Body Radiation Therapy (SBRT): 40-60 Gy delivered in 5-20 Gy fractions over 3-8 treatments
Four Dimensional Computed Tomographic Imaging (4DCT): Subjects undergo a total of 7 research-ordered four dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning.

Pulmonary Function Damage Reduction
All criteria and specifications in the standard of care arm are applicable for this arm, including the same 4DCT scans, and laboratory biomarker analysis. Subjects randomized to this arm of the trial will have the same prescribed radiation dose to the tumor volume and held to the same radiation dose criteria as the subjects in the standard of care arm (60-66 Gy using standard fractionation (1.8-2.0 Gy/fx) and 40-60 Gy stereotactic body radiation therapy (SBRT) hypofractionation). The fundamental difference will be radiation doses for these subjects will be redistributed away from regions predicted to cause the greatest reduction in pulmonary function if damaged.

n=61 participants at risk
Subjects undergo four-dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning. Subjects undergo laboratory biomarker analysis, including spirometry, diffusion capacity (DLCO), and lung volumes (FEV, FEV1). Subjects complete a self-assessment, RTOG defined acute evaluation toxicity evaluation, RTOG late toxicity evaluation, and constitutional assessment.
Radiation doses between 60-66 Gy using standard fractionation (1.8-2.0 Gy/fx) and 40-60 Gy stereotactic body radiation therapy (SBRT) hypofractionation schemes are utilized. Treatment volumes are at the discretion of the treating radiation oncologist and should follow standard of care.

Standard of Care
n=61 participants at risk
Subjects undergo four-dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning. Subjects undergo laboratory biomarker analysis, including spirometry, diffusion capacity (DLCO), and lung volumes (FEV, FEV1). Subjects complete a self-assessment, RTOG defined acute evaluation toxicity evaluation, RTOG late toxicity evaluation, and constitutional assessment.
Radiation doses between 60-66 Gy using standard fractionation (1.8-2.0 Gy/fx) and 40-60 Gy stereotactic body radiation therapy (SBRT) hypofractionation schemes are utilized. Treatment volumes are at the discretion of the treating radiation oncologist and should follow standard of care.
Laboratory Biomarker Analysis: Correlative studies
Standard fractionation: 60-66y Gy delivered in 1.8-2.0 Gy fractions over 30-36 treatments
Stereotactic Body Radiation Therapy (SBRT): 40-60 Gy delivered in 5-20 Gy fractions over 3-8 treatments
Four Dimensional Computed Tomographic Imaging (4DCT): Subjects undergo a total of 7 research-ordered four dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning.

Pulmonary Function Damage Reduction
n=55 participants at risk
All criteria and specifications in the standard of care arm are applicable for this arm, including the same 4DCT scans, and laboratory biomarker analysis. Subjects randomized to this arm of the trial will have the same prescribed radiation dose to the tumor volume and held to the same radiation dose criteria as the subjects in the standard of care arm (60-66 Gy using standard fractionation (1.8-2.0 Gy/fx) and 40-60 Gy stereotactic body radiation therapy (SBRT) hypofractionation). The fundamental difference will be radiation doses for these subjects will be redistributed away from regions predicted to cause the greatest reduction in pulmonary function if damaged.
Laboratory Biomarker Analysis: Correlative studies
Standard fractionation: 60-66y Gy delivered in 1.8-2.0 Gy fractions over 30-36 treatments
Stereotactic Body Radiation Therapy (SBRT): 40-60 Gy delivered in 5-20 Gy fractions over 3-8 treatments
Four Dimensional Computed Tomographic Imaging (4DCT): Subjects undergo a total of 7 research-ordered four dimensional computed tomographic imaging (4DCT) scans: 1 at simulation, and 2 scans at each of the 3 post-radiation therapy time points (3, 6, and 12 months). 4DCT determines lung tissue elasticity and for standard of care radiation treatment planning.
