摘要： 目的:探讨PET/CT显像在食管癌放射治疗中的临床价值。方法:对50例患者进行PET,CT,PET/CT常规检查,检测食管沟LN,大体肿瘤区GTV,与术后的病理条件下的检测结果进行回顾性分析,比较PET,CT,PET/CT三种方法在诊断食管癌淋巴结组转移上的敏感性、特异性、准确性。结果:共切取淋巴结107个,病理确定的转移淋巴结31个,平均直径1.4cm,PET确定的转移淋巴结26个,平均直径1.5cm,敏感性和特异性分别为57.5%和86.7%,CT确定的转移淋巴结26个,平均直径1.7cm,敏感性和特异性分别为47.5%和96.7%,18F-FDG-PET/CT确定淋巴结转移28个,平均直径1.5cm,敏感性和特异性分别为93.1%和94.7%。结论:18F-FDG-PET/CT诊断食管癌淋巴结转移的敏感性为93.1%,特异性为94.7%,准确性为94%。18F-FDG-PET/CT显像技术对于食管癌的放射治疗具有前瞻性意义。

Abstract: Objective:To evaluate the clinical value of the treatment of esophagealcarcinoma using PET-CT imaging.Methods:Analysis and comparison GTV and metastatic lymph nodes of 50 cases of esophageal cancer patients by using barium meal,PET,CT,PET / CT before radiotherapyin with esophageal cancer and statistical analysis.Results:A total of 107 lymph nodes were cut,pathological lymph node metastases identified 31,the average diameter is 1.4cm,PET identified metastatic lymph node 26,the average diameter of 1.5 cm,the sensitivity and specificity were 57.5% and 86.7%,CT to determine the 26 metastatic lymph nodes,the average diameter of 1.7 cm,the sensitivity and specificity were 47.5% and 96.7%,18F-FDG PET / CT identified 28 lymph node metastasis,the average diameter of 1.5 cm,the sensitivity and specificity were 93.1% and 94.7%.Conclusion:The sensitivity of FDG PET-Ctdiagnosis lymph node metastasis in esophageal cancer was 93.1%,specificity was 94.7%,and accuracy was 94%.18F-FDG PET / CT imaging has the forward-looking sense for esophageal cancer.
