Abstrakt: Neuroblastoma (NB) accounts for 15% of all pediatric cancer fatalities (NB). Biomarkers that facilitate early NB detection are needed because by the time of diagnosis, over half of NBs had spread. MicroRNA-21(miR-21) and miR-155 are involved in cancer biology due to their immune modulation functions. Altered monocyte subset distribution is thought to be involved in a number of solid tumors due to its immunological role. We aimed to investigate the expression levels of miR-21 and miR-155 and their association with circulating monocytes subsets in NB and to evaluate if they correlate to the disease pathogenesis and outcome.
Patients and Methods: This case control study involved 79 children classified into 39 newly diagnosed NB children and 40 age and sex matched healthy children. Real-time PCR was used to assess the expression of plasma miR-21 and miR-155. The frequency of circulating monocytes subsets was assessed by flow cytometry.
Results: NB group showed significant up-regulation in expression of miR-21(20.9 folds) and miR-155 (1.8 folds) when compared to the control group (p < 0.001) and (p = 0.02) respectively. Also, frequency of circulating intermediate monocytes revealed significant up regulation in children with NB. In NB patients, there was a positive correlation between miR-21 and frequency of total and intermediate monocytes (r = 0.5 p < 0.001 and r = 0.7, p < 0.001, respectively). We found no discernible differences when we compared study markers between the high risk and intermediate risk groups. In addition, no significant difference was seen in study markers when patients were sub-grouped according to their induction treatment response. ROC curve analysis revealed that miR-21 up-regulation distinguished NB in childhood at an AUC of 0.94 (82% sensitivity and 100% specificity) while miR-155 up-regulation had less capacity to distinguish NB in childhood at an AUC of 0.65 (38% sensitivity and 93% specificity).
Conclusion: miR-21 can be utilized as a sensitive biomarker for childhood NB development. In pediatric NB, miR-21 was linked to intermediate monocyte plasticity. Both, miR-21 and miR-155 had no impact on NB outcome.
