摘要
背景：N6-甲基腺苷（m6A）甲基化被称为肿瘤表修饰的研究热点，与之相关的甲基转移酶样3（METTL3）在胃癌中显著差异表达，但其临床价值尚未被总结。这项荟萃分析旨在评估METTL3在胃癌中的预后意义：使用PubMed、EMBASE（Ovid平台）、Science Direct、Scopus、MEDLINE、Google Scholar、Web of Science和Cochrane Library等数据库来确定符合条件的相关研究。研究终点包括总生存期、无进展生存期、无复发生存期、进展后生存期和无病生存期。用危险比（HR）和95%置信区间（CI）将METTL3的表达与预后相关联。进行了亚组分析和敏感性分析：本次荟萃分析共收集了 7 项符合条件的研究，涉及 3034 名胃癌患者。分析表明，METTL3的高表达与总生存率明显较低有关（HR = 2.37，95% CI 1.66-3.39，P P P P P P P P P结论：METTL3的高表达可预测胃癌的预后：METTL3的高表达可预测胃癌的不良预后，表明METTL3有望成为一种预后生物标志物。系统综述注册：https://www.crd.york.ac.uk/prospero，ID = CRD42023408519。
Prognostic significance of N6-methyladenosine-modified related chemotransferase METTL3 in gastric carcinoma: Evidence from meta-analysis.
Background: N6-methyladenosine (m6A) methylation is known as the research hotspot for tumor epimodification, and its associated methyltransferase-like3 (METTL3) is significantly differentially expressed in gastric carcinoma, but its clinical value has not been summarized. This meta-analysis aimed to evaluate the prognostic significance of METTL3 in gastric carcinoma.
Material and methods: Databases, including PubMed, EMBASE (Ovid platform), Science Direct, Scopus, MEDLINE, Google Scholar, Web of Science, and Cochrane Library, were used to identify relevant eligible studies. The endpoints included overall survival, progression-free survival, recurrence-free survival, post-progression survival, and disease-free survival. Hazard ratios (HR) with 95% confidence intervals (CI) were used to correlate METTL3 expression with prognosis. Subgroup and sensitivity analyses were performed.
Results: Seven eligible studies involving 3034 gastric carcinoma patients were recruited for this meta-analysis. The analysis showed that high METTL3 expression was associated with significantly poorer overall survival (HR = 2.37, 95% CI 1.66-3.39, P < 0.01) and unfavorable disease-free survival (HR = 2.58, 95% CI 1.97-3.38, P < 0.01), as did unfavorable progression-free survival (HR = 1.48, 95% CI 1.19-1.84, P < 0.01)/recurrence-free survival (HR = 2.62, 95% CI 1.93-5.62, P < 0.01)/post-progression survival (HR = 1.53, 95% CI 1.22-1.91, P < 0.01). Subgroup analysis found that high METTL3 expression was associated with worse overall survival in patients with Chinese (HR = 2.21, 95% CI 1.48-3.29, P < 0.01), in studies with sample source from formalin-fixed, paraffin-embedded tissues (HR = 2.66, 95% CI 1.79-3.94, P < 0.01), and the reported directly from articles group (HR = 2.42, 95% CI 1.66-3.53, P < 0.01). The subgroup analysis that was performed based on sample size, detected method, and follow-up showed the same results.
Conclusions: High expression of METTL3 predicts poor prognosis in gastric carcinoma, indicating promise for METTL3 as a prognostic biomarker.Systematic review registration: https://www.crd.york.ac.uk/prospero, ID = CRD42023408519.
