Abstract
Esophagectomy has been the traditional therapy for high-grade dysplasia and intramucosal cancer. Though surgery can completely resect the cancer and the affected lymph nodes, it carries significant morbidity and mortality (often exceeds 2%). New developments in endoscopy have provided less-invasive therapies that can also be used to stage tissue invasion of cancer; they include esophageal mucosal resection (EMR) and endoscopic submucosal dissection. Additional endoscopic therapies include photodynamic therapy, radiofrequency ablation (RFA) and argon plasma coagulation. Combining EMR that targets the cancer and RFA that targets the surrounding Barrett's esophagus offers an alternative to the operative approach when there is no lymph node metastasis. Arguments for surgical esophagectomy include concern for missed lymph node metastasis and incomplete endoscopic resection. Based on EMR's high neoplasia eradication rate and its fewer and more manageable complications, EMR, especially when combined with RFA, appears to be a viable alternative to surgery in early submucosal cancers, that is, sm1.
