Abstract:
OBJECTIVE:To evaluate the correlation of long non-coding RNA small nucleolar RNA host gene 1 (lnc-SNHG1) expression with clinical characteristics and prognosis in pediatric AML patients.
METHODS:209 newly diagnosed pediatric AML patients and 67 patients without malignant hematologic disease (as controls) who underwent bone marrow biopsy and with matched age and gender were enrolled in this study. The baseline characteristics of pediatric AML patients were recorded. Bone marrow samples from all the participants were collected before treatment, and lnc-SNHG1 expression in bone marrow mononuclear cells (BMMNC) was detected by qRT-PCR. The treatment response, event-free survival (EFS) and overall survival (OS) of pediatric AML patients were assessed as well.
RESULTS:lnc-SNHG1 expression in pediatric AML patients was higher than that in contros (P＜0.001); up-regulated expression of lnc-SNHG1 showed a good value in predicting the prevalence of pediatric AML with an area under curve of ROC of 0.837 (95%CI: 0.785-0.888) and correlated with the poor prognosis risk stratification (P=0.004) as well. Moreover, the up-regulated expression of lnc-SNHG1 related with lower complete remission (CR) rate in pediatric AML patients (P＜0.001), and further multivariate logistic regression analysis indicated that lnc-SNHG1 high expression was independent factor related with worse CR (P＜0.001). In addition, pediatric AML patients with high expression of lnc-SNHG1 had shorter EFS time (P＜0.001) and OS time (P＜0.001), further multivariate logistic regression analysis showed that lnc-SNHG1 high expression was independent factors for predicting worse EFS (P=0.001) and OS (P=0.015) in pediatric AML patients.
CONCLUSION:lnc-SNHG1 is up-regulated in pediatric AML patients and can be used as an independent predicting factor for poor prognosis of pediatric AML patients.
