Staging Strategies and Their Association With Prognosis and Therapy in Lung Cancer With Cystic Airspaces

This is a research study (not a treatment trial) examining whether the way a specific type of non-small cell lung cancer — one that appears with air pockets or cysts inside the tumor on a CT scan — is staged affects treatment outcomes and survival. Researchers will review existing medical records and imaging. **You may be eligible if...** - You have been diagnosed with non-small cell lung cancer (NSCLC) - You have already had surgery to remove the lung tumor - Your pre-surgery CT scan showed air-filled (cystic) spaces within the tumor - Complete pre-surgery CT imaging data is available **You may NOT be eligible if...** - You have a history of lung diseases that produce cysts (such as tuberculosis, emphysema, or certain genetic conditions) - You received chemotherapy, radiation, or targeted therapy before surgery - You had another cancer at the same time - Your pre-surgery CT imaging is incomplete or poor quality Talk to your doctor to see if this trial is right for you.
