Radiotherapy plays an important role in the treatment of locally advanced esophageal cancer. And, definitive chemoradiotherapy is widely accepted treatment methods for advanced esophageal cancer. Radiation dose-escalation has failed to improve local control or survivals. However, irradiation techniques have been advancing markedly. 3-dimensional radiotherapy, intensity modulated radiotherapy (IMRT), and particle beam therapy is a highly precise radiotherapy in which the dose distribution can be fitted according to the shape of tumor. Future Directions will evaluate the dose-escalation using highly precise radiotherapy and adequate radiation field for locally advanced radiotherapy.
