Less may be more: smaller lung surgery tested against standard removal

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.
