Less may be more: smaller lung surgery tested against standard removal
NCT ID NCT07169903
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compares two types of surgery for people with a specific kind of lung cancer (adenocarcinoma) that is 2-3 cm in size and has a low-to-intermediate grade. One surgery removes just the part of the lung with the tumor (segmentectomy), while the other removes an entire lobe (lobectomy). The goal is to see if the smaller surgery works just as well at preventing the cancer from coming back, while possibly helping patients keep more lung function. About 587 participants will be followed for 5 years after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
surgery (segmentectomy or lobectomy)
What this could lead to
If successful, this could show that a less extensive surgery (segmentectomy) is as effective as a larger one (lobectomy) for certain lung cancers, potentially preserving more lung function and improving recovery.
What could go wrong
This is a Phase 3 trial, but results are years away. The benefit may be small or not apply to all patients. Surgery always carries risks like infection or complications.
