Expression of cyclooxypenase-2 and the relation between cyclooxypenase-2 and CD_(105)in osteosarcoma / 肿瘤研究与临床

Objective To study the expression of cyclooxypenase-2(COX-2),prognosis of patients and the correlation between COX-2 and CD_(105)in osteosarcoma.Methods The expression of COX-2 and CD_(105)in human osteosarcoma was detected with immunohistochemistry.Then to count the microvessl density (MVD)were marked with CD_(105),The prognosis of the patients with osteosarcoma was analyzed by Cox multi- variate survival analysis.Results The positive rate of COX-2 expression was 77.5 %,The expression of COX-2 was positively correlated with surgical grade and metastasis of osteosarcoma;There were significant difference between surgical grade Ⅰ and Ⅱ b、grade Ⅰ and Ⅲ(P0.05);Metastatic cases had higher MVD than those without metastasis(P
