Abstract | BACKGROUND: METHODS: Serum samples from 254 previously untreated ML patients were examined to measure GP88 concentrations using a sandwich human GP88 ELISA kit. Immunohistochemical analyses were performed to examine GP88 tumor tissue expression. RESULTS: The median serum GP88 concentration of ML patients was 91.3ng/ml, and was significantly higher than that of the control group (median, 57.7ng/ml) (p<0.0001). Association between GP88 serum concentrations and overall survival (OS) was examined in patients with diffuse large B cell lymphoma (DLBCL) who had been stratified based on their serum GP88 concentrations. Kaplan Meier survival analysis showed that patients with serum GP88 concentrations of ≤116 and >116ng/ml, had 5-y OS rates of 70% and 50%, respectively (p=0.02). The immunohistochemical analyses of GP88 tumor expression revealed that DLBCL patients had lymphoma cells that were positive for GP88. CONCLUSIONS: High serum GP88 concentrations are associated with poor prognosis in patients with DLBCL.
