复发和抗拒性是食管癌患者治疗的一个挑战[1],因为对于这些患者来说,再放疗后疗效和高并发症是主要考虑的问题。最近在许多复发的肿瘤上,包括头颈部肿瘤、胶质瘤、肺癌和肠癌,再放疗的成功应用取得了令人满意的结果。现代精确放疗允许在肿瘤周围产生适形的剂量分布,降低邻近关键器官的放疗剂量,提高肿瘤的受量,如再联合化疗,将有可
Recurrence and resistance are a challenge for the treatment of patients with esophageal cancer [1], because the efficacy and high complication after reradiation are the main concerns for these patients. Recent successful applications in many recurrent tumors, including head and neck cancer, glioma, lung cancer and bowel cancer, have yielded satisfactory results. Modern precise radiotherapy allows to create a conformal dose distribution around the tumor, reduce the dose of radiotherapy adjacent to key organs and increase the amount of tumor, such as combined with chemotherapy, there will be
