Location characteristics of superficial esophageal squamous cell carcinoma.

ABSTRACT: The location-specific characteristics of superficial esophageal squamous cell carcinoma (ESCC) have not been determined. This study analyzed the locational characteristics of superficial ESCC. Medical records of patients with superficial ESCC treated between December 2008 and November 2024 at Pusan National University Yangsan Hospital were retrospectively reviewed. ESCC locations and final pathological results confirmed by surgery or endoscopic resection were compared. A total of 150 patients with 163 superficial ESCCs were analyzed. Lesions were located in in the upper thoracic (n = 16, 9.8%), mid-thoracic (n = 104, 63.8%), and lower thoracic regions (n = 43, 26.4%). Although upper thoracic lesions had higher deep submucosal cancer (62.5% vs. 29.8%, p = 0.015) and poorly differentiated ca
