This study examined the risk factors and treatment results of pediatric ALL in Thailand. This multicenter study included newly diagnosed children (< 18 years) with ALL in 19 centers between January 1, 2015, and December 31, 2019. Most of the 1,157 patients (97.6%) were treated according to ThaiPOG protocols. The genetic testing was performed in 71% of patients. The patients were classified as standard (n = 539), high (n = 402), and very high (n = 130) risks. The 5-year event-free survival (EFS) and overall survival (OS) rates were 75% (95% confidence intervals (CI), 72%-77.8%) and 81.7% (95% CI, 78.9%-84.1%), respectively. The 5-year EFS rates of the standard-, high-, and very high-risk groups were 78.5% (95% CI, 74.1%-82.3%), 73.6% (95% CI, 68.5%-78%) (p = 0.761), and 65% (95% CI, 55.1%-73.3%) (p = 0.001), respectively, and the 5-year OS rates were 86.9% (95% CI, 83.1%-89.9%), 77.3% (95% CI, 72.5%-81.4%) (p = 0.001), and 73.1% (95% CI, 63.7%-80.4%) (p = 0.001), respectively.

The primary endpoint was achieved with a median PFS of 25.4 months (95% CI, 15.7 to 29.0). However, a major limitation of idelalisib is its toxicity. With a median follow-up of 70.9 months, median OS was still not reached, and 5-year OS was 72.9% (95% CI, 61.3 to 86.6). We confirm that CXCR4 mutations had no impact on PFS or OS.

However, the biological functions and precise mechanisms of miR-525-5p remain unclarified in Burkitt's lymphoma (BL). This study aimed to explore the roles of miR-525-5p in BL, with the goal of ascertaining its regulatory effects on the nuclear factor-kappaB (NF-κB) signaling pathway by targeting Myeloid differentiation factor 88 (MyD88). The expression levels of miR-525-5p and MyD88 were measured by quantitative real-time PCR and immunohistochemical staining, respectively. The effects of miR-525-5p overexpression on BL cell proliferation, colony-forming, and migration were evaluated by cell counting kit-8, soft agar colony-forming, and transwell assays, while cell cycle and cell apoptosis were analyzed by flow cytometry. Possible interactions between miR-525-5p and MyD88 was examined via luciferase reporter assay. The expression of MyD88 and NF-κB signaling pathway-related proteins, including p65, p-p65, IκBa, and p-ΙκBa was determined by western blotting. BL cells overexpressing miR-525-5p were treated with phorbol 12-myristate 13-acetate (PMA), and Hoechst 33258 staining and Calcein AM/EthD-I staining were used to analyze the changes in chemotherapy sensitivity of BL cells to doxorubicin (DOX). Compared with reactive lymphoid hyperplasia, miR-525-5p was dramatically downregulated in BL tissues, while the rate of MyD88 protein positivity was significantly increased. Upregulation of miR-525-5p suppressed cell proliferation, colony-forming, and migration, induced cell cycle arrest and apoptosis, and enhanced the chemosensitivity to DOX in BL cells. MiR-525-5p targeted MyD88 to inhibit the activation of NF-κB signaling pathway. PMA treatment reactivated the NF-κB pathway and reversed apoptosis mediated by miR-525-5p overexpression. These findings revealed that miR-525-5p acts as a tumor suppressor, targeting MyD88 to modulate proliferation, cell cycle progression, and apoptosis in BL cells by regulation of NF-κB signaling pathway.</p>","PeriodicalId":8068,"journal":{"name":"Annals of Hematology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142566307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Race/ethnicity was categorized into three main subsets: non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB), and 'other races' that included Hispanics (H), American Indian/Alaskan Native (AI/AN), Asian or Pacific Islander (A/PI).

A multifactor logistic regression analysis model was used to assess the independent risk factors affecting critical illness in children with infection-associated HLH, and the Receiver Operating Characteristic (ROC) curve analysis was used to evaluate the predictive value of risk factors for critical illness in children with infection-associated HLH. Children in the critical group with HLH had a younger age at onset. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), gamma-glutamyl transferase (GGT), D-dimer (DD), and triglycerides (TG) were significantly higher in the critical group, while albumin (ALB) was significantly lower, showing statistical significance (P < 0.05). Multifactorial logistic regression analysis of age, ALB, and TG showed that younger age and lower ALB were associated with a higher risk of MODS in children with infection-associated HLH, with age and ALB being independent risk factors for critical illness. ALB predicted the ROC area under the curve for critical children with infection-associated HLH was 0.765 (95% CI: 0.643-0.888, P = 0.011), with the optimal cut-off value being 32.50 g/L (sensitivity = 68.3%, specificity = 84.2%); age predicted the ROC area under the curve for critical children with infection-associated HLH was 0.711 (95% CI: 0.570-0.851, P = 0.009), with the optimal cut-off value being 1.50 years (sensitivity = 70.7%, specificity = 68.4%).
