放射治疗(放疗)在食管癌的辅助治疗中发挥越来越重要的作用,通过术前或术后放疗缩小肿瘤体积和(或)使肿瘤降级,使得本来不能手术的患者能够享有手术治疗的机会,然而相同分期、相同病理类型的食管癌患者放疗后预后却有很大差异,对食管癌放疗敏感性相关的分子标志物的研究则有利于预测食管癌放疗疗效,为患者制订合理有效的治疗方案。 Radiation therapy (radiotherapy) plays an increasingly important role in the adjuvant treatment of esophageal cancer, which reduces the tumor volume and / or degrades the tumor by preoperative or postoperative radiotherapy and allows patients who would otherwise have no surgical treatment to have the opportunity to undergo surgery However, the same stage, the same pathological type of esophageal cancer prognosis after radiotherapy have very different prognosis of esophageal cancer radiosensitivity related molecular markers research is conducive to predict the efficacy of esophageal cancer radiotherapy for the development of patients with reasonable and effective treatment Program.
