Pulmonary Watershed Topographic Map Navigation for Lung Nodule Resection

This trial evaluates a new 3D mapping technique to guide surgeons in precisely removing small lung nodules while preserving as much healthy lung tissue as possible. **You may be eligible if...** - You have a small lung nodule in the outer two-thirds of your lung - Your lung cancer is early-stage (stage IA1 or IA2) based on clinical assessment - Your tumor is considered surgically removable - A preoperative 3D watershed analysis has been performed **You may NOT be eligible if...** - Surgical video or specimen records are unavailable - The surgeon cannot achieve an adequate margin around the nodule - The actual resection differs significantly from the surgical plan - Your final pathology shows a more advanced stage than expected - You have chronic lung diseases that complicate surgery - The surgeon determines a larger resection is needed Talk to your doctor to see if this trial is right for you.
