Kimura H, et al. - Via including a total of 104 superficial esophageal squamous cell carcinomas (SESCCs) in which Type B2 was observed by magnifying endoscopy, researchers examined risk factors for misdiagnosis in preoperative invasion depth staging. Using logistic regression analysis, the connection between misdiagnosis and endoscopic features, including distinct features, was assessed. Findings suggested that lesions with a small Type B2 area (<6 mm) and/or Type B2 vessels around erosion should be diagnosed as EP/LPM and lesions with distinct characteristics as SM2-3. Adjusted by these factors of misdiagnosis, the positive Type B2 predictive value improved significantly from 38% to 65%.
