Liquid Biopsy for Lung Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
The trial aims to assess the practicality of using a liquid biopsy—a blood test that detects tiny bits of DNA from lung cancer cells—to screen individuals at high risk for lung cancer. If a liquid biopsy indicates cancer, individuals might be more inclined to undergo a low-dose CT scan to confirm the results. This approach could help detect lung cancer earlier, making it easier to treat. The trial seeks participants who have smoked heavily, quit within the last 15 years, and are willing to provide a blood sample and potentially undergo a CT scan. As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could enhance early lung cancer detection.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this liquid biopsy is safe for lung cancer screening?
Research has shown that cell-free DNA liquid biopsies are generally safe for patients. In one study, the Galleri test, a type of liquid biopsy, accurately detected lung cancer, identifying it in most cases with a sensitivity of 78.4% and a specificity of 99.5%.
A liquid biopsy involves taking a blood sample to look for DNA from cancer cells. This method is easy on patients because it only requires a simple blood draw, unlike traditional biopsies that may need tissue samples from the body. Studies have not reported any major side effects, making it a low-risk option for patients.
Overall, cell-free DNA liquid biopsy is considered safe and does not involve significant adverse events. It is already used in some cases to check for cancer changes in people who cannot have a regular biopsy.12345Why are researchers excited about this trial?
Researchers are excited about the liquid biopsy for lung cancer because it offers a non-invasive method to detect cancer using a simple blood test. Unlike traditional methods like tissue biopsies or low-dose CT scans (LDCT), which can be invasive or expose patients to radiation, liquid biopsies analyze cell-free DNA in the blood to identify cancer markers. This method can potentially detect cancer earlier and with less discomfort for patients. Additionally, liquid biopsies may provide quicker results and be repeated easily to monitor cancer progression or response to treatment.
What evidence suggests that this trial's methods could be effective for lung cancer screening?
Research has shown that liquid biopsies, which test for tiny amounts of cancer DNA in the blood, hold promise for detecting lung cancer. In this trial, participants in Cohort A will undergo a liquid biopsy, with the option for a low-dose CT scan (LDCT) if results are positive. Conversely, participants in Cohort B will undergo an LDCT, with the option for a liquid biopsy on the same day. A clinical study found that the Galleri test, a type of liquid biopsy, correctly identified lung cancer 78.4% of the time and non-cancer 99.5% of the time. Sensitivity measures how often the test detects cancer when present, while specificity measures how often it correctly identifies the absence of cancer. High specificity means few false alarms, making it a reliable tool. Unlike traditional biopsies, liquid biopsies are non-invasive and can detect genetic changes in cancers, aiding early diagnosis. Overall, this method could help catch lung cancer earlier, possibly leading to better outcomes.12367

Are You a Good Fit for This Trial?
This trial is for English-speaking individuals aged 50-80 who are at high risk for lung cancer due to a smoking history of 20 or more pack-years and, if they've quit, it was within the last 15 years. They must consent to screening with liquid biopsy or CT scan and have insurance covering LDCT at specified centers. Excluded are those with any recent cancer diagnosis (except non-melanoma skin cancer) or symptoms of lung cancer.Inclusion Criteria
