Study 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%. 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.

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2018 (actual). Primary completion is estimated for Mar 2019, 13 months after the start.

Of 356 non-industry observational studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 126. This study's planned 13 months is below that.

Counting every sponsor, half of 498 studies reached it within 55 months; a quarter within 35 and three quarters within 83.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 31, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
