Use of a Cytokine Gene Expression Signature in Lung Adenocarcinoma and the Surrounding Tissue as a Prognostic Classifier

BackgroundA 17-cytokine gene expression signature in noncancerous hepatic tissue from patients with metastatic hepatocellular carcinoma (HCC) was recently found to predict HCC metastasis and recurrence. We examined whether the cytokine gene expression profile of noncancerous lung tissue could predict the metastatic capability of adjacent lung adenocarcinoma.
