Prognostic analysis of salvage esophagectomy after definitive chemoradiotherapy for esophageal squamous cell carcinoma: The importance of lymphadenectomy

Pts undergoing salvage esophagectomy after definitive chemoradiotherapy were evaluated for perdictors of survival.  5-year survival was 30%, which was related to tumor recurrence rather than residual tumor, complete resection, N status, M status, and dissection of more than 15 nodes.  Additional neck dissection was not found to provide additional benefit.
