18F-FDG PET-CT对食管癌术后放疗后局部复发的诊断价值

Clinical Value of 18F-FDG PET-CT for Local Recurrence of Esophageal Carcinoma After Postoperative Radiotherapy

目的评估18F-FDG PET-CT在食管癌术后放疗后局部复发中的诊断价值。方法回顾性分析16例食管癌术后放疗后临床怀疑复发而行检查患者的临床及影像学资料,结合细胞学及病理学结果分析其18F-FDG PET-CT检查结果。结果 16例患者中,12例吻合口局部代谢明显增高,以标准摄取值最大值SUVmax≥2.5为阳性诊断标准,18F-FDG PET-CT对局部复发的敏感性和特异性分别为100%、80%。结论18F-FDG PET-CT对食管癌术后放疗后局部复发有很好的诊断价值,是检测食管癌术后放疗后局部复发的有效手段。

Objective To evaluate the clinical value of 18F-FDG PET-CT imaging in the diagnosis of local recurrence of esophageal carcinoma after postoperative radiotherapy. Methods The clinical data of 16 patients with suspected recurrence after postoperative radiotherapy for esophageal carcinoma surgery were retrospectively analyzed.According to the results of cytology and pathology,18F-FDG PET-CT was analyzed. Results In the 16 patients,12 patients with anastomotic local metabolism increased significantly,with the maximum standard uptake value SUVmax ≥2. 5 for positive diagnosis standard,the sensitivity and specificity of 18F-FDG PET-CT for local recurrence of were 100% and 80%. Conclusion 18F-FDG PET-CT has good diagnostic value for local recurrence of esophageal carcinoma after postoperative radiotherapy. It is an effective method to detect the local recurrence of esophageal carcinoma after postoperative radiotherapy.
