Brief Summary

Cancer radiation treatment plans that employ lung functional avoidance methods require 3D maps that differentiate regions of healthy lung function from regions of functional compromised tissue to deliver sufficient dose to the tumor while preserving as much functioning lung as possible. Hyperpolarized xenon-129 MRI can provide maps of ventilatory function and gas exchange to the bloodstream. Improving treatment plans based on this novel imaging modality could reduce risk or severity of radiation pneumonitis and improve post-treatment quality of life.

Outcome Measures

Primary Outcomes (1)

• Changes in DLCO at 6-month post RT treatment.

  Subjects will have measurements of DLCO at baseline (before RT) and at 6-month post RT. An independent-sample t-test will be used to compare change in DLCO.

  1-year

Secondary Outcomes (4)

• Change in Quality of Life questionnaires from baseline to 6-month post-RT.

  1-year

• Change in HXe lung MRI metrics from baseline to 6-month post-RT.

  1-year

• Change in FEV1 from baseline to 6-month post-RT.

  1-year

• Incidence/severity of pneumonitis.

  1-year

Study Arms (1)

Guided Radiation Therapy for lung cancer using HXe MRI for functional lung avoidance and diagnosis.

EXPERIMENTAL

Patients with non-small cell lung cancer scheduled for radiation therapy will be voluntarily enrolled in this study. They will have their lung ventilation and function imaged with hyperpolarized xenon MRI. The 3D HXe images will be used in determining a functional lung avoidance treatment map. Patients will follow radiation therapy optimized for functional lung avoidance. At 6-month follow up the subjects will be imaged again with HXe to assess lung ventilation and function post-RT compared to baseline (pre-RT). Additionally, standard-of-care lung testing (DLCO, PFT) and quality-of-life questionnaires will be assessed at several time points during the study.

Combination Product: Hyperpolarized xenon MRI

Interventions

Hyperpolarized xenon MRI COMBINATION_PRODUCT

Patients with non-small cell lung cancer scheduled for radiation therapy willing to take part in this study will undergo hyperpolarized xenon MRI at several time points prior and post RT. Images will be used to determine radiation treatment maps for functional lung avoidance. Reported adverse events caused by radiation induced lung injury and post-RT changes in the lung function will be compared to standard-of-care.

Eligibility Criteria

• Age: 18 Years - 85 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients over 18 years with a diagnosis of non-small lung cancer and planned for a definitive course of radiation therapy.
• Preferred patients will have had successful radiation therapy for a prior lung cancer and developed a secondary lung cancer for which are to be treated.
• Other de-nuovo lung cancer patients planned for radiation therapy with lung heterogeneity from natural co-morbidities (e.g., COPD stage 3+).

You may not qualify if:

• Patients less than 18 years old
• Patients known to be pregnant - a positive pregnancy test will be used to respectively exclude pregnant patients,
• Any known contraindication to MRI examination
• Anyone with an implanted metal device
• Inability to provide informed consent
• A language, communication, cognitive or behavioral impairment that might interfere with fully informed participation in the study.
• History of uncompensated organ failure (i.e. organ failure that is not stabilized through medical intervention), which will be assessed by the PI.
• Homelessness or other unstable living situation
• Active drug or alcohol dependence
• Claustrophobia
• Subjects weighting more than 300 pounds.
• Subjects with chest size larger than the bore of MRI machine can accommodate
