Extent of surgical resection for esophageal and gastroesophageal junction adenocarcinomas.
The early-stage lymphatic dissemination in esophageal cancer poses challenges for adequate surgical treatment. The role of extensive lymph node dissections remains a matter of debate. Results of the only available large randomized controlled trial suggest that fit patients who have esophageal cancer are treated best by a transthoracic esophagectomy with extended en bloc (two-field) lymphadenectomy. For less fit patients or patients who have junctional or cardiac tumors, transhiatal esophageal resection could suffice. In patients who have truly "early" adenocarcinoma (ie, with high-grade dysplasia or intramucosal carcinoma) endoscopic resectional or ablative treatments may be suitable. When the tumor invades the submucosal layer, the high risk for lymph node involvement and tumor recurrence probably necessitates more extensive treatment schedules for definitive cure.
