Identification of a Plasma Proteomic Signature for Lung Cancer


About this study

The primary objective is to identify a panel of plasma and/or serum proteins that differentiates the absence or presence of lung malignancy in samples obtained from subjects enrolled in this IRB/EC approved study with pulmonary nodules.
