Endoscopic screening for esophageal squamous-cell carcinoma in high-risk patients: a prospective study conducted in 62 french endoscopy centers

Abstract

Lugol dye staining increases the sensitivity of esophageal endoscopy for the detection of high-grade dysplasia and cancer. The prevalence of dysplasia and cancer reached 9.9 % in group 1, and we therefore believe that an endoscopic screening program could be justified for patients with head and neck or tracheobronchial cancer.
