Metabolic Biomarkers in Thoracic Cancers

This study is examining biological markers (called metabolic biomarkers) found in blood and tissue samples from patients with thoracic cancers — cancers of the chest area, including lung cancer, cancers of the windpipe, and chest wall tumors. The goal is to better understand the underlying biology of these cancers, identify patterns that distinguish different cancer types, and potentially uncover new ways to predict outcomes or guide more targeted treatments in the future. **You may be eligible if...** - You are 18 or older, of any race or ethnic background - You have a known or suspected cancerous tumor in the chest area that requires surgery - Your care plan already includes a surgical biopsy or surgical removal of the tumor as part of your standard treatment **You may NOT be eligible if...** - You are not a surgical candidate — meaning surgery is considered medically unsafe or inappropriate for you - You have diabetes that is poorly controlled and not being effectively managed with medication Talk to your doctor to see if this trial is right for you.
