Which lung surgery leaves patients breathing easier? new study aims to find out
NCT ID NCT07477158
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares how patients feel after two minimally invasive surgeries for early-stage lung cancer: segmentectomy (removing a small part of the lung) and lobectomy (removing a whole lobe). Researchers will track shortness of breath, physical function, and quality of life for one year after surgery. 180 participants will answer questionnaires before surgery and at several follow-up points. The goal is to see which procedure leads to better breathing and well-being.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- minimally invasive lung surgery (segmentectomy or lobectomy via VATS or RATS)
- What this could lead to
- If it works, this could help doctors choose the surgery that gives patients less shortness of breath and better quality of life after lung cancer treatment.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures outcomes after standard surgery, so it won't test a new drug or cure. Results may not apply to all lung cancer patients.
