title: Multimodal endoscopic therapy for multifocal intraepithelial neoplasia and superficial esophageal squamous cell carcinoma - a case series.
abstract: Local endoscopic procedures are increasingly used and accepted treatments for unifocal superficial esophageal squamous cell carcinoma (SESCC). In multifocal SESCC, esophagectomy with or without chemoradiotherapy is often regarded as standard therapy. However, a combination of local endoscopic resection and new techniques such as radiofrequency ablation may play an increasing role in the treatment of selected patients with multifocal SESCC. The aim of this series was to evaluate the feasibility of a multimodal endoscopic approach. We report a case series of six consecutive patients from a European tertiary center who underwent endoscopic treatment for multifocal SESCC. The treatment comprised endoscopic mucosal resection using the cap technique or endoscopic submucosal dissection, in combination with radiofrequency ablation. The main outcome measure was complete tumor eradication after therapy and during the follow-up period. Using such an approach, complete eradication of cancer was achieved in all patients during follow-up. No major adverse events occurred. In conclusion, in selected patients with multifocal or residual SESCC, local resection techniques in combination with radiofrequency ablation may be safe and potentially curative alternative treatments.
