Abstract:
Objective To explore the clinical significance of some risk factor,such as blood calcium serum alkaline phosphatase (ALP) and hemoglobin (Hb) for predicting or diagnosing bone metastases from urinary bladder neoplasms.Methods A total of 35 patients diagnosed as urinary bladder neoplasms and bone metastasis based on the histopathologic analysis (bone metastasis group,BM),and 105 cases of age-,sex-and follow-up time matched urinary bladder neoplasms patients without bone metastasis (non bone metastasis group,NBM) were included in present study.The correlations between clinical-pathological parameters (blood calcium,ALP,Hb) and bone metastases from urinary bladder neoplasms were analyzed and the risk factors for predicting or diagnosing bone metastases were identified.Results The levels of blood calcium,ALP and Hb were significantly higher at first diagnosis and follow-up period in BM group than in NBM group (P＜0.05).Multivariate logistic regression analysis indicated that the levels of calcium,ALP and Hb at first diagnosis were the independent risk factors for predicting the later incidence of bone metastases (P＜0.05).The levels of calcium,ALP and Hb in follow-up period were the independent risk factors for diagnosing bone metastases (P＜0.05).Receiver operating characteristic (ROC) curves analysis showed that the levels of calcium,ALP,Hb may give a more accurate prediction on bone metastases (AUC:0.615,0.704,0.692;cut-off:2.55mmol/L,97.0U/L,101.5g/L,respectively) or diagnosing bone metastases (AUC:0.706,0.776,0.829;cut-off:2.46mmol/L,112.5U/L,103.5g/L,respectively).Conclusion The levels of blood calcium,ALP and Hb may be used to predict the risk of bone metastases for patients firstly diagnosed as urinary bladder neoplasms,and predict whether the patients will be complicated with bone metastases during follow-up period.
