摘要
食管癌三维适形放疗（3DCRT）和调强放疗（IMRT）疗效确切,与常规放疗相比局部控制率和生存率均有明显提高,治疗失败的主要原因仍然是局部未控制和复发.就目前而言提高局部控制不能单纯依靠提高靶区剂量,同期放化疗的应用更进一步改善了食管癌的治疗效果.
Three dimensional conformal radiotherapy （3DCRT） or intensity modulated radiotherapy （IMRT） is effective for esophageal carcinoma treatment. Compared with conventional radiotherapy, these high precision radiotherapies can significantly improve local control and overall survival. However, local recurrence is still the most common reason for treatment failure. To improve local control, increasing target dose alone is not sufficient, while concurrent chemoradiotherpy may enhance the treatment effect for esophageal carcinoma.
