Methods: The study was performedon 70 consecutive newly diagnosed pediatric acute lymphoblastic leukemia (ALL) patients, of which 56 were evaluatedfor both bone marrow miR-128 and let-7b (all 70 for let-7b) by real-time quantitative reverse transcriptase polymerasechain reaction (RT-qPCR). In addition, seven age and sex matched healthy controls were assessed. Results: miR-128expression was significantly higher in ALL patients compared with healthy controls (p<0.001). However, the expressionlevels of let-7b showed no statistical significant difference between the groups. No significant links were noted withclinical details, laboratory data and response to treatment. Conclusion: The results suggest that determination ofmiR-128 expression level may provide a tool for confirmation of a diagnosis of childhood ALL, follow up for responseof treatment and a possible predictor of early relapse. Any role of let-7b in pediatric ALL needs to be further assessed. %U https://journal.waocp.org/article_66498_f3d28e2705cd9a8b2be493648b5770e7.pdf
