ESCCHGDLGDNo dysplasiaNo pathologyFor the detection of an SPTFor the detection of an SPT/LGDWLE, white-light endoscopy; NBI, narrow-band imaging; ESCC, esophageal squamous cell carcinoma; HGD, high grade dysplasia; LGD, low grade dysplasia; SPT, second primary tumor.No NBI was used during one endoscopy owing to patient discomfort.No Lugol’s staining was used during 12 endoscopies because it had no additional diagnostic value for the assessment of SPTs, patient discomfort, or allergy.Number of SPTs detected with endoscopic screening technique/total number of SPTs detected in the included patients.Calculated for the total number of lesions with pathological confirmation (n = 51). Patients with nonsquamous lesions, including esophageal adenocarcinoma or gastric cancer, are not shown (n = 2).
