ABSTRACT
OBJECTIVE@#To detect the expression levels of FAM19A5 in patients with mantle cell lymphoma (MCL), and to determine the relationship between FAM19A5 and the prognosis of MCL patients.@*METHODS@#Twenty-five MCL patients were choosen in the study, cytometric bead assay was used to detected the concentration of FAM19A5 in serum and immunohistochemical analysis were used to detect the expression levels of FAM19A5 in lymph nodes. The relationship of the FAM19A5 expression in serum and tissue were analyzed, the relationship of FAM19A5 and clinical characteristics of MCL patients, treatment and prognosis of MCL patients was analyzed.@*RESULTS@#The average serum concentration of FAM19A5 in MCL patients was 90.55±38.24 (ng/ml), which was significantly higher than that in control (P=0.0461). The proportion of high, medium, and low expression of FAM19A5 in lymph nodes was 32%, 36% and 32%, respectively, which showed significant difference from that in control group (P=0.001). The expression of FAM19A5 in serum and lymph nodes showed significant correlation (r=0.8683,P=0.001). The serum concentration of FAM19A5 showed positive correlation with the proportion of Ki67 (P=0.0222, r=0.4554). The mean survival time without relapse/death of MCL patients with high, middle and low expression of FAM19A5 was 17, 27 and 37.5 months, respectively,which showed significant statistical difference (P=0.0360). ROC curve analysis showed that serum concentration of FAM19A5 could predict the therapeutic effect in MCL patients, the cut-off value was 91.49 ng/ml. The proportion of recurrent/death in AML patients with FAM19A5 >91.49 ng/ml was significantly higher than that in patients with FAM19A5<91.49 ng/ml (P=0.0156).@*CONCLUSION@#The expression level of FAM19A5 is increased in MCL patient, and patients with high expression of FAM19A5 are more likely to relapse or die. FAM19A5 may be a new prognostic marker and potential therapeutic target for MCL.
