摘要:目的:探討血清CA153和BAKP在乳腺癌骨轉移顯像診斷中的應用。方法:對92例乳腺癌患者的核素骨顯像結果、血清CA153和BAKP結果進行回顧性研究。結果:①血清CA15-3和B-AKP的值隨著骨轉移分期的增高而逐步升高,且差異顯著(P lt;0. 01);②血清CA15-3和B-AKP與骨轉移的數目呈正相關;③血清CA15-3 gt;25 U/mL時,骨轉移的陽性率為63.3%,血清CA15-3 lt;25 U/mL時,骨轉移的陰性預測值為94. 5%;血清B-AKP gt;20 U/L時,骨轉移的陽性率為59. 6%時,骨轉移的陰性預測值為73.5%;當血清CA15-3 lt;25 U/mL同時B-AKP lt;20 U/L時,骨轉移的陰性預測值為100%。結論:血清CA15-3和BAKP測定在乳腺癌骨顯像診斷中具有重要的應用價值。
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.
