Expression Of Cd147, Pcna, Vegf, Mmps And Their Clinical Significance In The Giant Cell Tumor Of Bones

Background: Giant cell tumor of bone (GCT) is a potentially malignant tumor. CD147 is a multifunctional protein, which expresses itself in many tumors. In this study, we have investigated the correlation between CD147 and PCNA, VEGF, MMPs expression in giant cell tumor of bones. We have also explored the relationship between its clinical pathology and prognosis. Results: A significant difference of the expression level of CD147, MMPs was found in cases of GCT with Jaffe grading and prognosis (P<0.05). But, it was not in accordance with the patient's age and sex. An expression of CD147 was positively correlated with MMP-9, VEGF, MVD, PCNA (r=0.271, P=0.025; r=0.411, P=0.000; r=0.872, P=0.000; r=0.394, P=0.001). Conclusion: The expression level of CD147 in giant cell tumors of bones is correlated with the development of cancers and relapse. There was a positive correlation between expressions of CD147 and MMP-9, VEGF, MVD, PCNA, and CD147. This is an important indicator in evaluating the malignant degree and prognosis of giant cell tumors of bone. It may be the new target for ensuring chemopreventive strategies.
