Popis: Background and Aims So far, long noncoding RNAs (lncRNAs) signatures in acute myeloid leukemia (AML) are poorly understood. The present study aims to explore the prognostic significance of eleven cancer-related lncRNAs in bone marrow (BM) samples from adult Egyptian AML patients. Materials and Methods In this study, we analyzed eleven lncRNAs using the qRT-PCR assay in the bone marrow (BM) of 79 de novo AML adult patients before receiving any therapy. Results Five lncRNAs out of 11 were aberrantly expressed, and two lncRNAs influenced significantly the patient’s overall survival (OS). LncRNA-XIST was favorable when overexpressed (in univariate and multivariate analysis, P -value = .001). LncRNA-GAS5 adversely affected the OS (only in multivariate analysis P -value = .02). Two other lncRNAs (UCA1 and HIFAL) impacted complete remission induction (CR) significantly in univariate analysis ( P -value = .046 for both). Furthermore, lncRNA-UCA1 affected CR significantly in multivariate COX regression analysis ( P -value = .004). The 4 previously mentioned lncRNAs were among the 9 downregulated lncRNAs. Instead, the only 2 upregulated lncRNAs (SNHG15, MALAT1) did not significantly influence neither CR induction nor OS. LncRNA-PTCSC3, a fifth lncRNA, emerged as the only one that could predict relapse occurrence in an upfront original BM sample. Conclusion Two lncRNAs out of eleven (lncRNA-XIST and GAS5) impacted OS, and two other lncRNAs (UCA1 and HIFAL) affected CR in adult de novo AML patients. LncRNA-PTCSC3 predict relapse, however, further validation is still required.
