Expression pattern of miR-16-2-3p and its prognostic values on pediatric acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is a debilitating illness that easily occurs in adolescents. microRNAs (miRNAs) are potential biomarkers for multiple diseases. This paper was to elaborate on the expression of in childhood ALL and its clinical values on ALL diagnosis and prognosis. First, serum expression in ALL children and healthy volunteers was measured using RT-qPCR. Next, diagnostic potential and prognostic values of on ALL were analyzed through receiver operating characteristic (ROC) curve, Kaplan-Meier survival curve, and multivariate Cox regression analysis, respectively. No significant difference was observed in the clinical baseline data between ALL patients and healthy children. ALL patients showed downregulated serum (0.65 ± 0.27) ( < .01), whose area under the ROC curve was 0.837 with a cut-off value of 0.745 (67.92% sensitivity, 96.94% specificity). ALL patients with higher expression had higher survival rates than those with lower expression. Low expression predicted poor prognosis of ALL patients. After adjusting LDH and lymphomyelocyte proportion ( = 0.003, HR = 0.003, 95%CI = 0.000-0.145), was recognized as an independent prognostic factor for ALL patient survival. Briefly, low serum expression in ALL children could aid ALL diagnosis and predict poor prognosis.
