Moreover, plasma level of POU3F3 could discriminate ESCC from normal controls with 72.8% sensitivity and 89.4% specificity, although the levels of HNF1A-AS1 and SPRY4-IT1 in plasma were less sensitive (32.7% and 48.2%) for ESCC detection. The gene discussed is HNF1A; the disease is esophageal squamous cell carcinoma.
