Abstract

Pyroptosis is a recently discovered programmed cell death that is involved in tumor formation, prognosis, and curative effect. Pyroptosis-related long non-coding ribonucleic acids (PR-lncRNAs) play key roles in tumorigenesis and tumor progression. However, the inherent relationship between PR-lncRNAs and the prognosis of pediatric acute myeloid leukemia (AML) remains unclear. For this reason, the association of PR-lncRNAs with the prognosis and tumor microenvironment features was analyzed using the Therapeutically Applicable Research to Generate Effective Treatment (TARGET) database. We classified three clusters based on PR-lncRNAs expressions and identified 841 differentially expressed PR-lncRNAs related to overall survival time. Seven key lncRNAs were then identified by least absolute shrinkage and selection operator (LASSO)-Cox and multivariate Cox. A signature based on these seven lncRNAs was also established, and the patients were separated into two groups according to their risk score. The high-risk group was characterized by poorer prognosis, lower expression of immune checkpoints, lower microsatellite instability or microsatellite stability (MSI-L/MSS), and lower drug sensitivity. The results demonstrated that PR-lncRNAs have a potential effect on the tumor immune microenvironment, clinicopathological features, and prognosis in pediatric AML. The nomogram and decision curve analysis suggested that the risk score is one of the most accurate of any other and provided a basis for the exploration of the immune microenvironment of the cell pyroptosis-associated subtypes in children with AML and the construction of a prognostic model with seven key PR-lncRNAs, which provides an approach to evaluate the prognosis of pediatric AML patients.
