The performance of ZBTB4 mRNA content in peripheral blood in the diagnosis of pancreatic cancer was evaluated using ROC diagnostic curves based on the expression levels; the ROC results indicated that ZBTB4 mRNA content in peripheral blood was of high diagnostic significance with an area under the ROC curve of 0.873 (Fig. 6B). The gene discussed is ZBTB4; the disease is pancreatic neoplasm.
