Abstract
145 Background: We tried to analyze and deduce a treatment guideline after endoscopic resection of superficial esophageal squamous cell carcinoma in a retrospective analysis. Methods: Medical records of 37 patients who had been treated by endoscopic resection during a 6-year period in single institution were retrospectively analyzed. Results: Mean tumor size was 11.5±5.5 mm (range 3-31). Thirty-one lesions (83.8%) were treated by endoscopic submucosal dissection and 6 lesions by endoscopic mucosal resection (16.2%). En bloc resection rate and complete resection rate was 91.9% and 81.8%, respectively. The tumor invasion depth was diagnosed as epithelium: 5(13.5%), lamina propria mucosa: 12 (32.4%), muscularis mucosa: 10 (27.0%), submucosa: 10 (27.0%) respectively. The lymphovascular invasion was 3 lesions (8.1%). The rates of adverse events were 13.5% including 3 cases (8.1%) of perforation. Ten patients of the invasion depth as muscularis mucosa and submucosa received additional treatments including 6 patients of esophagectomy, 3 patients with radiotherapy and 1 patient with chemoradiotherapy. One patient of lamina propria received radiotherapy due to resection margin positive. The median follow-up duration was 22 month (range, 4-79) and there was no recurrence or metastasis during follow-up. Conclusions: We propose that adequate tailored management strategy after endoscopic resection of superficial esophageal squamous cell carcinoma may provide the favorable clinical results in outcome in treating early stage esophageal carcinoma.
