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。 Chemotherapy combined chemotherapy is the main method of non-surgical treatment of esophageal cancer. Conventional radiotherapy due to the normal tissue dose limit, the tumor dose can not be improved, the effect is not satisfied. In recent years, with the application of three-dimensional conformal radiotherapy, the accurate target area delineation and good dose distribution have greatly improved the radiotherapy effect of esophageal cancer. On this basis, the application of concurrent radiotherapy and chemotherapy to further improve the therapeutic effect of esophageal cancer.
