摘要
目的评价18F-2-氟代脱氧葡萄糖正电子发射型断层成像技术(PET-CT)诊断食管癌术后复发转移的临床应用价值。方法复阅并分析2003年6月至2004年6月同期行PET-CT和CT检查的食管癌术后复发转移患者31例的PET-CT和CT影像资料及临床资料,评价其敏感性、特异性和准确性。结果本组31例患者共检查出43处病变部位。PET-CT用于本组患者临床诊断的准确性为97.7%,敏感性为100%,特异性为85.7%;CT分别为77.3%,61.7%和78.6%,PET-CT敏感性高于CT(χ2=4.161,P=0.041)。结论PET-CT对食管癌术后复发转移的诊断敏感性高于CT,对食管癌术后复发转移的检测有重要意义。
Objective To evaluate the clinical value of the whole-body （18） F-fluoro-deoxy-Dglucose positron emission tomography with computerized tomography （PET-CT） for recurrence and distant metastasis after curative resection of the esophagus cancer. Methods From June 2003 to June 2004, thirty-one patients with clinical or radiologic suspicion of recurrent disease underwent conventional diagnostic work-up, including a spiral CT scan, and a dedicated whoh-body PET-CT. All cases were examined by pathology or followed-up for 6 months. Results Among the 31 cases, recurrences were found in 23 patients, and 43 recurrent lesions were detected, including 14 perianastomotic lesions and 43 regional and distant hsions. For the diagnosis of recurrence, the accuracy, sensitivity and specificity of PET-CT were 97. 7%, 100%, and 85. 7%, while those of conventional CT were 77.3%, 61.7%, and 78. 6% respectively. The sensitivity of PET-CT was significantly higher than that of conventional CT （100% vs 61.7% ; X^2 = 4. 161, P = 0. 041） . Conclusions The sensitivity of PET-CT is higher than that of conventional CT. PET-CT will play an important roh in the diagnosis of postoperative recurrence and metastasis of esophageal
