近年来随着对食管癌根治术后失败模式的研究,发现局部区域淋巴结复发是主要的失败原因之一。食管癌根治术后预防性放射治疗的靶区根据术后常见复发的部位有针对性预防照射,避免大范围照射引起的并发症,从而对提高局部晚期以及淋巴结阳性食管癌患者生存率有意义。全文就食管癌根治术后预防性放射治疗价值及照射靶区的研究进展作一综述。
In recent years, with the failure mode of esophageal cancer after radical resection, found that local regional lymph node recurrence is one of the main causes of failure. Preventive radiotherapy for esophageal cancer after radical radiotherapy target area according to the common postoperative recurrence of the targeted prevention of radiation, to avoid the complications caused by a wide range of radiation, and thus improve the survival rate of locally advanced and lymph node-positive esophageal cancer patients. The article reviews the value of prophylactic radiation therapy after radical resection of esophageal cancer and the research progress of irradiation target area.
