摘要 放化疗综合治疗是食管癌非手术治疗的主要方法。以往常规放疗因受到正常组织的剂量限制,肿瘤剂量无法提高,疗效不满意。近年来,随着三维适形放疗的应用,其准确的靶区勾画、良好的剂量分布,使食管癌的放疗效果有了明显的提高。在此基础上,同期放化疗的应用更进一步改善了食管癌的治疗效果。 Chemoradiotherapy is the main therapeutic modality for unresectable esophageal carcinoma. The curative effect of conventional radiotherapy is not satisfied. Because of the normal tissue dose constraints, the tumor dose cannot be improved. In recent years ,three-dimensional conformal radiotherapy with the accurate target outline and a good dose of distribution, has significantly improved the effect of radiotherapy for esophageal carcinoma. On this basis, concurrent chemoradiotherapy further improve the effectiveness of the treatment for esophageal carcinoma.
