The use of radiotherapy in the management of carcinoma of the esophagus and gastro-esophageal junction has undergone much evolution over the past 2 decades. Advances to define its role have been slow with meta-analyses often providing the most useful data. In spite of this many institutions around the world are divided about the role of radiotherapy in this disease and attribute different roles to radiotherapy based on clinical stage, tumor site and histology. The purpose of this review is to try to define the role of radiotherapy given our current knowledge base and to review which current and future trials may fill the gaps of knowledge that we currently have. It will also highlight the difficulties in making firm recommendations about the use of radiotherapy especially in a time when technology and treatments are rapidly evolving.
Core tip: This review describes the history and develop-ment of radiotherapy in the pre-operative setting for resectable esophageal cancer. In particular it focuses on data from multicenter phase II and phase III trials as well as meta-analyses from across the world. The review concludes with a discussion about the role of new radiation technologies in the management of esophageal cancer.
