ABSTRACT
Objective To explore the feasibility of Lugol's iodine staining in association with P53 oncoprotein test to detect early esophageal cancer and precancerous lesions through endoscopy. Methods Lugol's iodine was sprayed on esophageal mucosa under endoscopy in 78 patients with suspected early malignancy. Severe dysplasia which taken from unstained position by iodine were prepared immunohistochemically for P53 oncoprotein study. Then endoscopic mucosal resection (EMR) was performed to these severe dysplasia with P53 oncoprotein- positive mucosa. Results There were 31 unstained areas (25 patients) including squamous cell carcinomas (n=3) and severe dysplasias (n=16). Expression of P53 was found in 7 severe dysplasia (43.8% ),and 1 carcinoma in situ was found by EMR. Conclusion This modified method seemed feasible not only to detect early esophageal cancer,but also to resect severe dysplasia mucosa selectively by EMR.
