Functional Lung Avoidance Radiation Therapy Using Hyperpolarized Xenon-129 MRI

Detailed Description
Customized 3D planning of radiation therapy for lung cancer delivers a lethal dose to the tumor region while avoiding important structures (spine) and organs (esophagus, heart, lungs). Since radiation dose to functioning lung is associated with acute radiation pneumonitis and chronic radiation fibrosis, researchers seek to shift dosage preferentially away from lung regions with highest function. Several lung functional imaging modalities have been investigated (ventilation-perfusion SPECT and PET, 4DCT, hyperpolarized 3He). These studies indicate that regional ventilation is not the optimal biomarker. What is needed is a high-resolution imaging modality, tolerable to patients who have difficulty holding their breath, that delineates regions of full lung function warranting preservation, and also identifies regions whose function is irrevocably gone.
The investigators propose a translational study applying Hyperpolarized Xenon (HXe) MRI to improve lung-health outcomes for lung cancer patients treated with radiation therapy. This study will focus on a patient cohort with significant heterogeneity: new patients with lung cancer and GOLD stage 3+ emphysema as a comorbidity and patients receiving RT for their second (primary) lung cancer. Optimizing radiation therapy treatment plans could provide a statistically significant benefit within a manageably small patient cohort. Maps will delineate three regions of functionality: regions of full function, having both ventilation and gas exchange to blood (where radiation should be reduced), regions where function is irrevocably absent (where radiation dose can be increased), and regions where function may be present or recoverable (where radiation should remain at the normal dose limit). In the first year the investigators will conduct an open-label Phase 1 clinical trial to optimize the hardware and functional imaging protocols, as well as generate and perform targeted RT treatment in a limited number of patients, with safety as the primary endpoint.

Description
Inclusion Criteria:

- 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.

---|---|
Experimental: Standard-of-care Radiation Therapy for lung cancer using HXe MRI for diagnosis.
Patients with non-small cell lung cancer scheduled for radiation therapy will be voluntarily enrolled in this study, where 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.
However, for this part of the study, subjects will still follow the standard-of-care radiation treatment plan.
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.
|
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 maps for functional lung avoidance and post-RT changes in the lung function and compared to standard-of-care assessment methods.

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