Serum Markers as Predictors of Esophageal Squamous Dysplasia and Early Cancer
Abstract:
Objective Squamous dysplasia is the precursor lesion for esophageal squamous cell carcinoma (ESCC). A primary screening test for ESCC which identified this lesion could lead to a reduction in disease-specific mortality and provide clues to early detection of ESCC. Methods We conducted a population-based screening study in Linzhou, China, a region with high rates of ESCC. All subjects provided blood samples and underwent endoscopy with Lugol s iodine staining and biopsy. We selected a subset of 84 subjects st...
