Detailed Description
PRIMARY OBJECTIVES:
I. Assess diffusion-weighted MRI as an early predictor for tumor response in patients with non-small cell lung cancer (NSCLC).
II. Establish the potential of individualized radiotherapy targeting of radioresistant tumor sub-volumes.
OUTLINE:
Patients undergo diffusion-weighted MRI within 4 weeks of radiation start (baseline), during the second week of radiation therapy, during the fourth week of radiation therapy, and at 3 months after radiation therapy (post-treatment). Patients also undergo standard of care 4-dimensional (4D) computed tomography (CT) and fludeoxyglucose F 18 (FDG)-positron emission tomography (PET) at the same time points.

Intervention / TreatmentIntervention / Treatment |
|---|---|

Experimental: Diagnostic (diffusion-weighted MRI, 4D CT, FDG-PET)
Patients undergo 15 imaging studies: 5 chest CT scans, 5 chest MRI scans, 5 PET scans.
Each scan will be obtained before treatment begins, weeks 2 and 4 during radiation therapy, 3 months and 1 year following radiation therapy.
THe chest CT obtained pre-treatment, at 3 months post treatment and 1 year post treatment are considered routine and would be obtained regardless of study participation.
The pre-treatment PET scan is also considered routine.
All other scans are being done for the purposes of this research.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Measurement of gross tumor volume and involved lymph nodes
Time Frame: Up to 3 months
|
A paired sample t-test could be applied to test the difference between MRI, CT, and PET-CT contours.
Parameters used for comparison will include volume size, volume overlap, such as Dice similarity coefficients and Jaccard index, and surface distance maps including Hausdorff distance.
|
Up to 3 months
|
|
Change in functional response
Time Frame: Baseline to 3 months
|
Patients will be classified into responders and non-responders based on their PET signal which will serve as the reference method for response assessment.
Although this is a little different from the three group analysis of variance (ANOVA) used in the power calculation, it is expected that there will be similar high power when the partial responders and non-responders are combined.
Receiver operating characteristic (ROC) analysis will be used to define a threshold of apparent diffusion coefficient (ADC) change to stratify between metabolic responders vs. non-responders.
|
Baseline to 3 months
|
|
Spatial concordance of multimodality imaging for whole image registration
Time Frame: Up to 3 months
|
A paired sample t-test will be used.
|
Up to 3 months
|
|
Temporospatial registrations of radioresistant sub-volumes
Time Frame: Up to 3 months
|
A paired sample t-test will be used.
ROC analysis will be performed only for radioresistant sub-volumes to identify which diffusion weighted-MRI functional signal thresholds correlate with levels of tumor activity defined on PET.
|
Up to 3 months
