Low-dose CT Scan for Lung Cancer
(SHIELD Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate how effectively the blood test GuardantLUNAR-2 detects cancer in individuals at high risk. It specifically targets those undergoing routine lung cancer screenings with low-dose CT scans. Suitable candidates include current or recent smokers (those who quit within the last 15 years) with a history of smoking at least 20 pack-years (an average of one pack a day for 20 years). Participants must agree to a blood draw during their CT scan visit and commit to a year-long follow-up. As a Phase 2 trial, this research measures the blood test's effectiveness in an initial, smaller group, allowing participants to contribute to significant advancements in cancer detection.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are taking anti-cancer or certain immune-modifying drugs, you may not be eligible to participate.
What prior data suggests that the GuardantLUNAR-2 test and low-dose CT scan are safe for lung cancer screening?
Research shows that the GuardantLUNAR-2 test is generally easy for people to handle because it is just a blood test. Blood tests are common and safe, and no specific problems have been reported with the GuardantLUNAR-2 test.
The low-dose CT scan is a regular part of lung cancer screening. Studies indicate it is safe and effective for detecting lung cancer in high-risk individuals. Although it uses a small amount of radiation, this is considered safe for regular check-ups.
Overall, available research indicates that both the blood test and the low-dose CT scan are safe for participants.12345Why are researchers excited about this trial?
Researchers are excited about the GuardantLUNAR-2 test because it offers a non-invasive way to screen for lung cancer by analyzing blood samples, potentially making early detection easier and more accessible. Unlike traditional low-dose CT scans, which require imaging equipment and radiation exposure, this blood test could provide a simpler, safer, and quicker alternative. By identifying cancer-related signals in the blood, the GuardantLUNAR-2 test aims to catch lung cancer at an earlier stage, which could significantly improve treatment outcomes.
What evidence suggests that the GuardantLUNAR-2 test and low-dose CT scan are effective for detecting high frequency cancer?
Research has shown that the GuardantLUNAR-2 test holds promise for detecting cancer. In earlier studies, this blood test correctly identified 76.3% of 12 specific types of cancer. For early-stage cancers, it detected 53.5% of stage I–II cases, indicating its potential to find cancer early, which is crucial for successful treatment. In this trial, participants in the Lung Cancer Screening Cohort will undergo standard low-dose CT scanning according to guidelines, and an investigational blood draw will evaluate the GuardantLUNAR-2 test's effectiveness in early lung cancer detection. Although more research is needed, these results suggest it could be a valuable tool for early cancer detection, including lung cancer.36789
