Application of a novel examination of esophageal cell collector-esophageal exfoliative cytology in early esophageal cancer screening
Objective To evaluate the diagnostic efficacy of a novel test of esophageal cell collector-esophageal exfoliative cytology in early screening of esophageal cancer.Methods This study included eligible medical examination population in Sichuan Provincial People's Hospital,Nanchong Central Hospital,and Yanting County People's Hospital.They were subjected to gastroscopy and new esophageal cell collection.Gastroscopy-pathology results were taken as the gold standard,the diagnostic efficacy of this test in different esophageal lesions was evaluated.ROC curves analysis was performed to evaluate its screening efficacy for early esophageal cancer.Results The novel test of esophageal cell collector-esophageal exfoliative cytology had the best screening ability for high-grade intraepithelial neoplasia with 90.91%of sensitivity and 99.737%of specificity.For the screening of early esophageal cancer,the area under the ROC curve(AUC)was 0.946(95%CI=0.899~0.994).The sensitivity was 84.20%.The specificity was 96.20%and the Yordon index was 0.804.Conclusions The novel test of esophageal cell collector-esophageal exfoliative cytology has a specificity of over 90%for the screening of each esophageal lesion.It is suitable as a screening tool for early esophageal cancer.
