Abstract
目的 探讨18F-FDG PET/CT显像和血清肿瘤标志物(CEA、NSE、CFRA21-1)检测联合在肺单发结节诊断中的价值.方法 91例经病理确诊的肺单发结节患者进行18F-FDG PET/CT显像,同时取静脉血4mL分离取血清在低温冰箱保存,用放免法集中测量血肿瘤标志物CEA、NSE、CFRA21-1.结果 18 F-FDG PET/CT检查对肺单发结节恶性肿瘤检出的灵敏度为84.8%(56/66),对肺单发结节诊断的准确率为86.8%(79/91);18 F-FDG PET/CT显像联合血肿瘤标志物(CEA+NSE+CFRA21-1)检测对肺单发结节恶性肿瘤检出的灵敏度为93.9%(62/66),对肺单发结节诊断的准确率为95.6%(87/91),和18F-FDG PET/CT检查相比,灵敏度和准确率差异具有统计学意义(P均﹤0.05).结论 18 F-FDG PET/CT显像和血肿瘤标志物(CEA、NSE、CFRA21-1)检测联合能提高对肺单发结节诊断的灵敏度和准确性,有较高的临床应用价值.
