Weight loss could be key to spotting lung cancer sooner
NCT ID NCT06717334
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 2 times
Summary
This study looks at whether people with unexplained weight loss who are at high risk for lung cancer are more likely to develop the disease. Researchers will use low-dose CT scans and blood tests to screen 409 participants over one year. The goal is to see if adding weight loss to current screening guidelines helps find lung cancer at an earlier, more treatable stage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Low Dose CT imaging, blood draws, screening questionnaire
- What this could lead to
- If successful, this could show that adding unexplained weight loss to screening criteria helps catch lung cancer earlier, potentially improving survival.
- What could go wrong
- This is an observational study, not a treatment trial. It may not prove that screening changes outcomes, and results may not apply to all smokers.

Inclusion Criteria: * Eligible for American Cancer Society lung cancer screening, as follows as per the discretion of the screening team: * Age 50-80 years old * At least 20-pack year history of smoking * Weight loss of 3-10%, defined as UWL, within any timeframe over the past in the 18 months prior to enrollment, that cannot be attributed to an underlying medical condition at the discretion of the enrolling investigator * Note that patients who have 3-10% weight may still be enrolled if the enrolling investigator does not conclude that the weight loss can be attributed to the patient's intentional efforts. * Documented weight loss can be self-reported or extracted from weights obtained during physician visits. However, if self-reported weight loss is contradicted by weight loss documented in the medical record (e.g. a patients states that (s)he lost 10 lbs in the past 6 months, but a weight documented in the medical record does not support that history), the measured and quantified weight change will be used to ascertain eligibility * Life expectancy greater than 1 year, per assessment of the treating clinician. Exclusion Criteria: * Currently pregnant or trying to become pregnant via self-report * Prior history of recent CT scan of the chest either through LDCT screening or with a scan of the chest (standard, not LDCT) performed within the past 12 months * Prior history of NSCLC ○ Note that patients with a history of diagnosis of non-lung cancers are eligible for the study. * Currently undergoing or referred for diagnostic evaluation due to clinical suspicion for malignancy (e.g., referred to a medical or surgical oncologist, or scheduled for biopsy on the basis of a suspicious imaging abnormality). * Patients with a germline pathogenic genetic variant who have undergone whole body MRI within the past 12 months * Unable to comply with study procedures
