摘要:目的:探讨血清CA153和BAKP在乳腺癌骨转移显像诊断中的应用。方法:对92例乳腺癌患者的核素骨显像结果、血清CA153和BAKP结果进行回顾性研究。结果:①血清CA15-3和B-AKP的值随着骨转移分期的增高而逐步升高,且差异显著(P lt;0. 01);②血清CA15-3和B-AKP与骨转移的数目呈正相关;③血清CA15-3 gt;25 U/mL时,骨转移的阳性率为63.3%,血清CA15-3 lt;25 U/mL时,骨转移的阴性预测值为94. 5%;血清B-AKP gt;20 U/L时,骨转移的阳性率为59. 6%时,骨转移的阴性预测值为73.5%;当血清CA15-3 lt;25 U/mL同时B-AKP lt;20 U/L时,骨转移的阴性预测值为100%。结论:血清CA15-3和BAKP测定在乳腺癌骨显像诊断中具有重要的应用价值。
Abstract: Objective: To evaluate the diagnosis value of serum CA153 and BAKP measurements for scanning bone metastatic images in patients with mammary Cancer. Methods: Retrospective study on the bone scan images and serum CA153 (with CLIA) and bone alkaline phosphatase (BAKP, with ELISA) levels were performed in 92 patients with confirmed mammary gland cancer. Results: ①The serum levels of CA153 and BAKP were increased step by step along with the advancement of bone metastatic grading from M0 to M3 with significant difference between values in successive gradings (P lt;0. 01).②The levels of CA153 and BAKP were significantly positively correlated. ③With serum CA153 gt;25 U/mL the positive rate of bone metastasiswas 63.2%, with CA153 lt;25 U/mL the negativepredictive value of bone metastasis was 94.5%, with BAKP gt;20 U/L,the positive rate of bone metastasis was 596%, with BAKP lt;20 U/L, the negative predictive value of bone metastasis was 73. 5%.However with Serum CA153 lt;25 U/mL and BAKP lt;20 U/L, the negative predictive value of bone metastasis was100%. Conclusion: The combined measurement of the serum CA153 and BAKP levels would play an important role for diagnosis of bone scan images in patients with prostate cancer.
