Imaging Techniques for Lung Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two imaging techniques to determine if they reveal the same details for lung cancer. The study compares a new imaging method, SPECT/CT using 99mTc-EC-DG, against the standard PET/CT using 18F-FDG, to detect lung cancer lesions. Participants with confirmed or suspected lung cancer, based on previous tests, who are not currently receiving cancer treatment, qualify as good candidates for this study. As a Phase 3 trial, it represents the final step before FDA approval, offering participants the opportunity to contribute to potentially groundbreaking advancements in lung cancer imaging.
Do I need to stop my current medications to join the trial?
The trial protocol does not specify whether you need to stop taking your current medications. However, if you are undergoing any current treatment for cancer, you would not be eligible to participate.
Is there any evidence suggesting that this trial's imaging techniques are likely to be safe?
Research has shown that 18 F-FDG, a common substance used in PET/CT scans, is generally safe for people. It is widely used in medical imaging and has a strong safety record.
For the investigational agent 99m Tc-EC-DG, earlier studies suggest it is also safe for imaging lung cancer. One study found that using 99m Tc-EC-DG was practical and safe, with a dose similar to what will be used in this trial. The radiation levels from 99m Tc-EC-DG in these studies were similar to other medical imaging tests, which are generally considered safe when used correctly.
Although any radioactive material carries risks, studies so far show it is well-tolerated, and no unexpected side effects have been observed.12345Why are researchers excited about this trial?
Researchers are excited about these imaging techniques for lung cancer because they offer potentially more accurate and efficient diagnosis options. Unlike traditional imaging methods, which often rely on standard PET/CT scans, the 18 F FDG imaging agent is used with PET/CT to highlight areas of increased glucose metabolism, common in cancer cells, to better pinpoint tumors. Meanwhile, the 99m Tc ECDG imaging agent is distinctive because it combines with SPECT/CT imaging, potentially offering a different perspective by targeting glucose transporters and providing detailed images with less radiation exposure. These innovative approaches could lead to earlier and more precise detection of lung cancer, significantly impacting patient outcomes.
What evidence suggests that these imaging techniques are effective for lung cancer?
This trial will compare two imaging techniques for lung cancer: 18 F-FDG and 99m Tc-EC-DG. Research has shown that 18 F-FDG PET/CT scans are highly accurate in determining lung cancer stages, with one study finding an 87% accuracy rate in assessing cancer advancement. This accuracy aids doctors in understanding the cancer's severity. Meanwhile, early results suggest that 99m Tc-EC-DG, another imaging method under study, can also effectively image lung cancer, similar to 18 F-FDG. Both techniques provide clear images of the cancer, which is crucial for treatment planning.678910

Are You a Good Fit for This Trial?
This trial is for adults with confirmed lung cancer or strong clinical and CT evidence of it, who haven't started treatment yet. If they've had lung cancer before, they must have finished therapy at least 3 months ago. Participants need to agree to a tissue diagnosis if not already done.Inclusion Criteria

Trial Overview
The study compares two imaging techniques: SPECT/CT using a tracer called 99mTC-EC-DG versus PET/CT with the standard tracer 18F-FDG. It aims to see if SPECT/CT can match PET/CT in identifying primary and metastatic lung lesions.
