Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. 10-20% of the patients present with bone marrow (BM) involvement which predicts a worse survival. This study aimed to determine the prognostic significance of serum miR-222-3p, miR-26b-5p, EBV-miR-BHRF1-2-5p, and EBV-miR-BHRF1-2-3p and correlate their levels to clinical and haematological markers in DLBCL with special emphasis on the lymphocyte-monocyte ratio (LMR) and neutrophil-monocyte ratio. We also studied the role of BM BMI1 and PIM2 proteins in predicting BM infiltration. Serum miRNAs were studied on 40 DLBCL and 18 normal individuals using qRT-PCR. BMI1 and PIM2 proteins were studied on BM biopsies by immunohistochemistry. The results were correlated with clinical and follow-up data. All the studied miRNAs were dysregulated in DLBCL serum samples. BMI1 and PIM2 were expressed in 67% and 77.5% of BM samples, respectively. LMR was significantly associated with disease-free survival (DFS) (P = 0.022), miR-222-3P (P = 0.043), and miR-26b-5p (P = 0.043). EBV-miR-BHRF1-2-3p was significantly correlated to haemoglobin level (P = 0.027). MiR-222-3p, miR-26b-5p, and EBV-miR-BHRF1-2-5p expressions were significantly correlated to each other (P = 0.001). There was no significant correlation between the studied markers and follow-up data. LMR is a simple method for predicting survival in DLBCL. MiR-222-3p and miR-26b-5p may be implicated in an immunological mechanism affecting patients' immunity and accordingly influence LMR. The correlation between miR-222-3p, miR-26b-5p, and EBV-miR-BHRF1-2-5p may indicate a common mechanism among the 3 miRNAs that may explain DLBCL pathogenesis.
弥漫性大 B 细胞淋巴瘤 (DLBCL) 是最常见的非霍奇金淋巴瘤类型。10-20%的患者存在骨髓 (BM) 受累，这预示着预后更差。本研究旨在确定血清 miR-222-3p、miR-26b-5p、EBV-miR-BHRF1-2-5p 和 EBV-miR-BHRF1-2-3p 的预后意义，并将其水平与 DLBCL 的临床和血液学标志物相关联，特别强调淋巴细胞-单核细胞比值 (LMR) 和中性粒细胞-单核细胞比值。我们还研究了 BM BMI1 和 PIM2 蛋白在预测 BM 浸润中的作用。使用 qRT-PCR 研究了 40 例 DLBCL 和 18 例正常人的血清 miRNA。通过免疫组织化学研究 BM 活检中的 BMI1 和 PIM2 蛋白。结果与临床和随访数据相关联。所有研究的 miRNA 在 DLBCL 血清样本中均失调。BMI1 和 PIM2 在 67%和 77.5%的 BM 样本中表达。LMR 与无病生存 (DFS) 显著相关 (P = 0.022)、miR-222-3P (P = 0.043) 和 miR-26b-5p (P = 0.043)。EBV-miR-BHRF1-2-3p 与血红蛋白水平显著相关 (P = 0.027)。miR-222-3p、miR-26b-5p 和 EBV-miR-BHRF1-2-5p 之间的表达呈显著相关性 (P = 0.001)。研究标记物与随访数据之间无显著相关性。LMR 是预测 DLBCL 生存的一种简单方法。miR-222-3p 和 miR-26b-5p 可能参与影响患者免疫的免疫机制，并因此影响 LMR。miR-222-3p、miR-26b-5p 和 EBV-miR-BHRF1-2-5p 之间的相关性可能表明这 3 个 miRNA 之间存在共同机制，该机制可能解释了 DLBCL 的发病机制。
