Abstract: Described herein are multifactorial methods for detecting, diagnosing or aiding in the diagnosis of lung disorders or disease, e.g., lung cancer. The methods disclosed utilize multiple diagnostic paradigms, for example, to improve diagnostic sensitivity, specificity, negative predictive value and/or positive predictive value over each of the paradigms alone. For example, a clinicogenomic model is disclosed for lung cancer diagnosis which combines clinical factors and gene expression, particularly a sensitive and specific gene expression biomarker.
