Could your lifestyle or genes cause lung cancer before 50? new study investigates.
NCT ID NCT04640259
First seen Jun 26, 2026 · Last updated Aug 05, 2026 · Updated 3 times
Summary
This 100% remote study surveys 250 people diagnosed with non-small cell lung cancer before age 50. Participants answer questions about their environment, lifestyle, and family history, and may donate blood. The goal is to uncover factors linked to genetic changes that drive young lung cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help identify risk factors and genetic patterns that lead to lung cancer in younger people, potentially guiding future prevention or early detection strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It relies on self-reported surveys and voluntary blood samples, which may have biases or limited data. Results may not directly change care.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
A minimum of 250 subjects distributed with at least 50 subjects among the most common driver mutation groups will be enrolled into the study: 1. EGFR (del19 and L858R) - 50 subjects 2. ROS1 - 50 subjects 3. ALK - 50 subjects 4. KRAS - 50 subjects 5. Other Groups: 1. Uncommon activating mutation for which specific targeted therapy exists (RET fusion, NTRK fusion, BRAF V600E, MET Exon14 skipping mutations, other activating EGFR mutations) - 25 subjects 2. Non-targetable other mutations (p53, NF1, ATM, PIK3CA, RB, non-V600E BRAF, NTRK mutation) or no identified mutation. - 25 subjects Subjects with more than one mutation will be included.
