Trial summary

Lung cancer is the most common cause of cancer death in Canada. For approximately 30% of patients that present with locally-advanced non-small cell lung cancer (NSCLC), the standard treatment is curative-intent concurrent chemoradiotherapy. Outcomes remain poor, with 5-year survival of only 20%. Read more about this study

  • Ages Any age
  • All sexes

Study population: Ultimately, the sample size was based upon practical considerations and that 20 NSCLC patients (10 Stage I/II and 10 Stage III) could be accrued relatively easily from new patient clinics, while sufficiently providing enough evidence to validate the imaging techniques to be used as a non-invasive measure for future clinical trials aimed at reducing or mitigating radiation-induced cardiac toxicity.

About this study

Official title: Identification of Acute Radiation-induced Cardiac Toxicity After Non-small Cell Lung Cancer Radiotherapy With Advanced Multi-modality Imaging (RICT-LUNG)

Lung cancer is the most common cause of cancer death in Canada. For approximately 30% of patients that present with locally-advanced non-small cell lung cancer (NSCLC), the standard treatment is curative-intent concurrent chemoradiotherapy. Outcomes remain poor, with 5-year survival of only 20%. Despite the long-held belief that higher radiation doses lead to improved overall survival (OS), the landmark randomized trial (RTOG 0617) showed the opposite. The investigators hypothesize that the inferior survival observed may be due to unexpected heart toxicity as secondary analysis revealed that the heart dose was a strong predictor of inferior OS. Up to now, change in heart function is typically detected histologically, requiring autopsy tissue. Therefore, a non-invasive marker of early heart damage is required. Hybrid PET-MRI has become available in Canada only recently. The ability to simultaneously perform metabolic imaging with functional and tissue imaging allows for novel assessment of heart toxicity. The primary objective is to examine the utility of hybrid PET-MRI and DCE-CT to assess acute changes in heart function and to measure inflammation before, and six weeks after NSCLC radiotherapy. A pilot of 20 patients with Stage I-III NSCLC will be enrolled. The findings of this study will aid in the design of new studies to reassess dose escalation for locally advanced NSCLC while limiting the risk of heart toxicity. FDG PET will be used to simultaneously assess both cardiac inflammation and tumour response. Quantitative DCE-CT will also be used to measure ventilation and perfusion changes in the normal lung and tumour after radiotherapy, providing image data that can comprehensively assess both tumour response and potential toxicity in both the heart and lungs. Such information is crucial in understanding the disease and its response to treatment. This data will also aid in the design of radiation techniques that spare the heart in other patients with any thoracic malignancies, including breast cancer, lymphoma, and esophageal cancer.

Read the detailed description

The investigators propose a longitudinal imaging pilot study composed of 20 Stage I-III NSCLC patients before, and six weeks after standard radiotherapy using a hybrid 3T-PET/MRI system (Biograph mMR, Siemens Healthcare) and a GE Revolution 256-slice CT scanner. The imaging protocol is designed to detect acute changes in myocardial perfusion, inflammation, edema, left ventricular ejection fraction, normal lung and tumour perfusion, and tumour metabolism. During each imaging session, patients will receive an 18F-FDG PET scan to image macrophage-related inflammation and tumour metabolism, MRI to identify edema, mature fibrosis or scar, and Dynamic contrast enhanced CT (DCE-CT) imaging to image perfusion and (LVEF). All images will be fused and rendered with radiation treatment planning dose distributions. Parameters such as Standard Uptake Value (SUV) will be used to compare PET scans, while heart volume and presence of Gadolinium enhancement will be used to compare MRI scans. Blood flow, blood volume, and permeability will be used to compare CT scans. Blood tests including Erythrocyte Sedimentation Rate (ESR), high sensitivity C-reactive protein, and troponin at each timepoint will also be performed to detect cardiac inflammation. Comparisons between Stage I/II and Stage III patients will allow us to determine whether our metrics for heart changes is radiation related. Relative differences from the six-week time point to baseline will be correlated with the radiation dose distribution to attempt to define a dose-response relationship between radiation dose and cardiac toxicity.
