Abstract:
Objective To determine the serum levels of cross-linked telopoptide of type Ⅰ collagen (ICTP),alkaline phosphatase (ALP) in patients with primary malignant bone tumor,primary benign bone tumor and malignant tumor metastasized to the bone,and to explore the clinical value of ICTP and ALP in identification and diagnosis of bone tumor.Methods Sixteen primary malignant bone tumor patients,16 primary benign bone tumor patients and 18 malignant tumor metastasized to the bone patients in 2012 were studied.Serum ALP was assayed by SFBC rate method and ICTP by enzyme linked immunosorbent assay (EIA).Results The serum levels of ICTP was not significantly different between primary benign bone tumors and normal control group (P ＞ 0.05),but the other between-groups had statistically significant difference (P ＜ 0.05).The serum levels of ALP in malignant tumor metastasized to the bone was significantly higher than the rest of the group (P ＜0.01),but the difference between the remaining groups was not statistically significant (P ＞ 0.05).The area under roc curve (AUC) of ICTP for diagnosis of primary benign bone tumors,malignant tumor metastasized to the bone,primary malignant bone tumor (0.923,0.926,0.874) was higher than the ALP (0.354,0.702,0.865).Conclusions Serum ICTP and ALP were sensitive and convenient biochemical indices which reflected metabolism of patients with bone tumor.Serum ICTP was more specific and sensitive than ALP and they have clinical importance for differential diagnosis as an index of bone tumor.
