This study was aimed to investigate the expression of osteopontin (OPN) in central nervous system leukemia (CNSL) and to understand its clinical significance. The expression level of OPN in serum of 62 pediatric patients (22 cases of CNSL, 20 cases of acute leukemia without extramedullary infiltration and 20 cases of nontumor patients) and 19 cases of CNSL with complete remission (CR)were assayed by ELISA; the expression changes of OPN mRNA in bone marrow of the CNSL patients were detected by RT-PCR. The results indicated that the serum OPN level was significantly higher in CNSL group (25.21 ± 6.87 ng/ml) than that in acute leukemia group (13.24 ± 2.73 ng/ml) (P < 0.001) and nontumorous group (3.14 ± 1.60 ng/ml) (P < 0.001); the serum OPN level (4.35 ± 1.50 ng/ml) in CNSL group with CR decreased obviously (P < 0.001) after therapy; RT-PCR analysis showed that the expression of OPN mRNA was higher in CNSL group as compared with other two groups (P < 0.01). It is concluded that the OPN expression may play a role in central nervous system infiltration of leukemia, the mechanism of which remains to need further clinical exploration.
