Considering both tumor locations together (Fig. 3A), we have found CXCL1 transcript level (sensitivity = 84.21, specificity = 82.98, ROC Area = 0.8694, threshold = 0.1389) as a strong candidate biomarker for distinguishing cancerous from normal tissue, and IL6 (sensitivity = 71.70, specificity = 70.83, ROC Area = 0.7858, threshold = 0.8144) and IL1b (sensitivity = 76.79, specificity = 70.83, ROC Area = 0.7902, threshold = 0.1958) as weaker candidate biomarkers. The gene discussed is IL6; the disease is neoplasm.
