摘　　要：目的分析^(18)F-脱氧葡萄糖(^(18)F-FDG)PET/CT在胃癌术后复发及转移监测中的应用价值。方法将83例胃癌术后患者作为研究对象,所有患者均进行^(18)F-FDG PET/CT检查,患者病历资料完整,胃癌术后复发及转移病灶均根据病理组织检查和临床随访证实。结果83例胃癌术后患者病理组织检查和临床随访证实胃癌术后复发者14例,肿瘤转移者36例,转移病灶共74个。^(18)F-FDG PET/CT检查显示复发病灶SUVmax为(6.15±2.28),较未复发病灶的高(3.88±1.70,P<0.05)。^(18)F-FDG PET/CT诊断胃癌术后复发的灵敏度为85.71%,特异度为97.10%,准确度为95.18%。^(18)F-FDG PET/CT检查显示有33例患者出现病灶转移,共70个转移病灶,其诊断胃癌术后腹膜转移的准确度为92.31%,诊断腹腔、腹膜后淋巴结转移的准确度为92.31%,诊断远处转移的准确度为91.43%。结论^(18)F-FDG PET/CT在胃癌术后复发及转移监测中具有重要应用价值。Objective To analyze the application value of^(18)F-deoxyglucose(^(18)F-FDG)PET/CT in monitoring recurrence and metastasis after gastric cancer surgery.Methods 83 patients after gastric cancer surgery were enrolled as study objects.All patients underwent^(18)F-FDG PET/CT.The case data of patients were complete.The recurrence and metastasis lesions after gastric cancer surgery were confirmed by pathological tissue examination and clinical follow-up.Results Of the eighty-three patients after gastric cancer surgery confirmed by pathological tissue examination and clinical follow-up,there were 14 cases with recurrence and 36 cases with tumor metastasis.There were 74 metastasis lesions.^(18)F-FDG PET/CT showed that SUVmax of recurrence lesions was higher than that of non-recurrence lesions[(6.15±2.28)vs.(3.88±1.70)](P<0.05).The sensitivity,specificity,and accuracy of^(18)F-FDG PET/CT for diagnosis of recurrence after gastric cancer surgery were 85.71%,97.10%,and 95.18%,respectively.^(18)F-FDG PET/CT examination showed that there were 33 patients with lesion metastasis.And there were 70 metastasis lesions.The accuracy rates of^(18)F-FDG PET/CT for diagnosis of peritoneal metastasis after gastric cancer surgery,abdominal and retroperitoneal lymph node metastasis,and distant metastasis were 92.31%,92.31%,and 91.43%,respectively.Conclusion^(18)F-FDG PET/CT is of significant application value in monitoring recurrence and metastasis after gastric cancer surgery.
