Abstract
Surgical resection remains the mainstay of potentially curative therapy for gastroesophageal junction (GEJ) tumors. However, because of the location of the tumor at the boundary between the esophagus and stomach, GEJ tumors have been a source of controversy in regard to their definition, classification, staging and surgical management. The definition of GEJ tumors was addressed with the development of the three-tiered Siewert's classification scheme. There remain many controversies regarding the appropriate surgical approach and the extent of the lymphadenectomies for these tumors. For locally advanced, resectable GEJ tumors, an aggressive surgical resection should be considered and the approach predicated by tumor location as defined by the Siewert's classification. Limited resections for earlier stage tumors have also been evaluated.
