全身骨显像联合血清CYFRA21-1检测诊断肺癌骨转移的价值

目的:探讨肿瘤标志物CYFRA21-1检测和核素骨显像对肺癌骨转移的诊断价值.方法:对138例肺癌患者及56例良性肺疾病患者行SPECT全身核素骨显像的同时,用电化学发光法测定血清CYFRA21-1,将两者的结果进行比较,结果:骨转移组CYFRA21-1值明显高于未转移组,未转移组高于对照组;转移组骨显像多数为阳性(97.4%),未转移组及对照组骨显像个别为阳性,均由手术或外伤引起.结论:全身骨显像与CYFRA21-1联合检测有助于提高骨转移的检出率.

The Value of Combined Examination of Serum CYFRA21 -1 Level and Bone Scan in the Diagnosis of Bone Metastasis in Lung Cancer

Objective To explore the value of combined examination of serum tumor markers CYFRA21-1 and bone scan in the diagnosis of bone metastasis in lung cancer. Methods Bone scan and serum CYFRA21-1 levels (with CLIA) determination were performed in 138 patients with lung cancer and 56 patients with benign lung diseases. Results The serum level of CYFRA21-1 were significantly higher in patients with bone metastasis than those in patients without bone metastasis. The levels were also higher in patients without bone metastasis than those in controls. Most patients with bone metastasis had positive results in bone scan (97.4%), only 2 of the 78 had negative bone scan but positive with CT or MRI. A few patients without bone metastasis and controls had positive bone scan results, caused by previous operation or injury. Conclusion The combined detection of CYFRA21-1 and bone scan were valuable in the diagnosis of bone metastasis of lung cancer.
