Abstract:
Objective To explore the application value of serological markers in the screening of malignant tumor bone metastasis.Methods A total of 113 patients with malignant tumor bone metastasis first diag-nosed in a hospital from June 2023 to February 2024 were selected as case group.Another 80 patients with malignant tumor without bone metastasis diagnosed in the same period were selected as the control group.The levels of serological markers[serum calcium(Ca),parathyroid hormone(PTH),Ca/PTH,procollagen type 1 amino-terminal propeptide(P1NP),beta-C-terminal telopeptide of type 1 collagen(β-CTX)and N-terminal mid-fragment of osteocalcin]were compared between the two groups.Receiver operating characteristic(ROC)curves were plotted to analyze the value of serological markers in screening for bone metastases of lung canc-er,prostate cancer and breast cancer.Multivariate Logistic regression was used to analyze the related factors of malignant tumor bone metastasis.Results The levels of Ca,Ca/PTH,β-CTX and P1NP in case group were significantly higher than those in control group,while PTH in case group was lower than that in control group,with statistical significance(P<0.05).ROC curve results showed that Ca,PTH,Ca/PTH,P1NP and β-CTX had high efficacy in screening malignant tumor bone metastases,and the area under the curve(AUC)was 0.718,0.699,0.712,0.648 and 0.593,respectively.Multivariate Logistic regression analysis showed that Ca/PTH and P1NP were the influencing factors of bone metastasis in malignant tumor(OR=5.036,1.013,P<0.05).The AUC of Ca,PTH and Ca/PTH screening for bone metastasis of lung cancer were 0.781,0.652 and 0.669,respectively.The AUC of β-CTX and P1NP screening for bone metastasis of prostate cancer were 0.800 and 0.815 respectively.The AUC of Ca and P1NP screening for breast cancer with bone metastasis was 0.751 and 0.794,respectively.Conclusion Serological markers(Ca,PTH,Ca/PTH,P1NP and β-CTX)are valuable in screening for malignant tumor bone metastasis.
