放射治疗是食管癌治疗的一种有效治疗手段,但食管癌放疗后局部区域复发是最常见的失败模式,复发率高达44%~61%。食管癌放化疗后局部区域复发的处理:(1)争取挽救性根治切除,患者及家属不容易接受;(2)再程放疗,需严格选择适应证,而且疗效差并发症多;(3)支架置入和扩张术,只能短暂解决食管畅通的问题,很快肿瘤生长再度出现梗阻,远处转移;(4)光动力治疗是食管癌放疗后复发的较好治疗选择;

Radiation therapy is an effective treatment for esophageal cancer treatment, but local recurrence after esophageal cancer radiotherapy is the most common failure mode, the recurrence rate as high as 44% to 61%. Radiotherapy and chemotherapy after esophageal local recurrence of the treatment: (1) for salvage radical salvage, patients and their families are not easy to accept; (2) re-radiotherapy, need to be strictly selected indications, and poor curative effect and complications; (3) Stent implantation and dilatation, esophageal cancer can only be a temporary solution to the problem of unblocked, and soon again tumor growth obstruction, distant metastasis; (4) photodynamic therapy is a better choice for esophageal cancer recurrence after radiotherapy;
