目的 探讨18F-氟代脱氧葡萄糖 (18F-FDG)正电子发射断层显像术/计算机 体层扫描(PET/CT)显像联合血清糖类抗原 19-9(CA19-9)对宫颈癌复发及转移的诊断 价值。方法 回顾性分析2015年1月-2018 年1月我院收治的62例宫颈癌根治术后疑 似复发和转移患者的临床资料。所有患 者均行18F-FDG PET/CT检查，以组织病理 学或随访结果为“金标准”，评价PET/ CT检查、血清CA19-9检测以及两者联合检 查对宫颈癌复发及转移的诊断价值，并比 较差异性。结果 18F-FDG PET/CT、联合 检查诊断对宫颈癌复发及转移的灵敏度、 特异度、准确率均高于血清CA19-9检测 (P﹤0.05)，且与组织病理学或随访结果 的吻合度高(kappa值=0.763、0.950，P﹤ 0.05)。结论 18F-FDGPET/CT显像可清晰准 确显示宫颈癌患者术后复发及转移情况， 联合血清CA19-9联合诊断价值较高，有助 于全面评估患者病情。

Objective To explore the diagnostic value of 18F-fluorodeoxyglucose (18FFDG) positron emission tomography/computed tomography (PET/CT) imaging combined with serum carbohydrate antigen 19-9 (CA19-9) on the recurrence and metastasis of cervical cancer. Methods The clinical data of 62 patients with suspected recurrence and metastasis after radical resection of cervical cancer from January 2015 to January 2018 were analyzed retrospectively. All patients were given 18F-FDG PET/CT examination. Histopathology or follow-up results were regarded as gold standards to evaluate the diagnostic value of PET/CT, serum CA19-9 and combined examination for recurrence and metastasis of cervical cancer and compare the differences. Results The sensitivity, specificity and accuracy of 18F-FDG PET/CT and combined examination for recurrence and metastasis of cervical cancer were higher than those of serum CA19-9 (P<0.05), and they were highly consistent with histopathology or follow-up results (kappa value=0.763, 0.950, P<0.05). Conclusion 18F-FDG PET/CT imaging can clearly and accurately show the recurrence and metastasis of patients with cervical cancer. Serum CA19-9 has high diagnostic value, and can comprehensively evaluate the patients' conditions.
