食管癌根治性放疗后局部复发诊断和再治疗进展

Progress in diagnosis and treatment of local recurrence after radical radiotherapy for esophageal cancer

食管癌放化疗后复发的诊断需要依靠影像学（食管X片、CT、EUS、PET—CT）和食管镜的动态变化和活检病理的结合。复发后再程治疗主要有挽救性手术、放（化）疗、内镜下黏膜切除术、化疗等治疗手段，总生存较姑息治疗有所提高，但还不能令人满意。复发的早期发现是提高疗效的根本。

The diagnosis of local recurrence after radiochemotherapy for esophageal cancer requires the combination of multiple imaging methods （esophageal X-ray, computed tomography, endoscopic uhrasonography, and positron emission tomography-computed tomography ） , dynamic changes in esophagoscopy, and biopsy. The main treatment of recurrence includes salvage surgery, radiochemotherapy, endoscopic mucosal resection, and chemotherapy. The overall survival rate after the above treatment is improved compared with palliative care but still unsatisfactory. Early diagnosis of recurrence is fundamental for improved treatment outcomes.
