The purpose of this study is to see if mesothelin, a protein found in blood and lung tissue, can serve as a marker of early-stage lung cancer. Markers may be used to help diagnose cancer, predict how well a patient will respond to treatment, monitor a patient’s response to treatment, or determine if cancer has returned.
In this study, researchers are comparing mesothelin levels in patients with adenocarcinoma of the lung before surgery to mesothelin levels in patients after surgery. They are examining mesothelin levels in patients’ blood and in lung tissue removed at the time of their cancer surgery. Their goal is to determine if this marker can serve as a predictor of cancer recurrence in patients with lung cancer.
