Previous studies validated the prognostic significance of lymphocyte to monocyte ratio (LMR) in patients with solid tumors and some hematologic malignancies. However, the correlation between LMR and Myelodysplastic Neoplasms (MDS) was unclear. The study intends to investigate the prognostic impact of LMR on MDS patients. 91 newly diagnosed MDS patients were included in this retrospective study. The cut-off of LMR was 3.2 by X-Tile. All patients were divided into the low LMR group (<3.2) and the high LMR group (≥3.2). Clinical characteristics were compared between the two groups. Patients in the high LMR group (n = 67) had better OS (P = 0.007) from the Kaplan-Meier survival curves. The results of the univariate analysis demonstrated that LMR was a prognostic factor for OS [hazard ratio (HR) = 2.070, 95%CI 1.201-3.571, P = 0.009]. After multivariate cox analysis, low LMR was confirmed to be an independent predictor of poor OS in MDS patients (HR = 1.872, 95%CI 1.084-3.230, P = 0.024). LMR, a representative marker of systematic inflammation and immune response, has potential prognostic significance in MDS patients. [ABSTRACT FROM AUTHOR]

Controlling nutritional status (CONUT) score, based on three indexes including serum albumin (ALB), total cholesterol (CHO), and absolute lymphocyte count (ALC), has been closely associated with the prognosis of cancer patients. Multiple studies revealed the significance of CONUT score in hematological malignancies, including diffuse large B-cell lymphoma (DLBCL), peripheral T-cell lymphoma (PTCL), multiple myeloma (MM), and leukemia. This review aimed to explore the prognostic role of CONUT score in hematological malignancies. We conducted this review through Pubmed to summarize the published studies on the CONUT score in hematological malignancies, using the terms: Controlling nutritional status, CONUT score, hematological malignancy, lymphoma, multiple myeloma, and leukemia. CONUT score can reflect not only the nutritional status but also the inflammatory status of patients with hematological malignancies. It can assist in predicting the survival of patients with DLBCL, PTCL, MM, adult T-cell leukemia (ATL), myelodysplastic syndrome (MDS), and acute myeloid leukemia with myelodysplasia related changes (AML-MRC). CONUT score plays an important role in predicting the prognosis of patients with hematological malignancies. [ABSTRACT FROM AUTHOR]

Objectives: Circular RNA (circRNA), a covalently closed loop structure lacking poly-adenylated tails, has attracted attention with the rapid development of its detection techniques such as bioinformatics and RNA sequencing. CircRNA plays important roles in several cell signaling pathways that are associated with cancer biogenesis, including acting as miRNA sponges, transcriptional regulators, protein adaptors and protein translators. The role of circRNA in hematological malignancy has been revealed recently. The purpose of this study was to explore the role of circRNA in hematological malignancy. Methods: A comprehensive literature review was conducted through Pubmed to summarize the published evidence on the circRNAs in hematological malignancies. English literature sources since 1976 were searched, using the terms circRNA, hematological malignancy. Results: CircRNAs can regulate the gene expression of hematological malignancies mainly through adsorbing several miRNAs. Some circRNAs are potential biomarkers and therapeutic targets in hematological malignancies, such as acute myloid leukemia (AML), chronic myeloid leukemia (CML) and chronic lymphocytic leukemia (CLL). Conclusion: CircRNAs play an important biological function and have great diagnostic and prognostic value in hematological malignancies. [ABSTRACT FROM AUTHOR]
