[摘 要] 目的:基于 m1A 相关基因在多个数据库中差异表达情况与临床参数建立新的胰腺癌风险评估模型,为胰腺癌治
疗和预后分析提供理论依据。方法:通过分析 m1A 相关基因在 TCGA⁃GTEx 数据库中的差异表达,利用 Cox 分析与 LASSO 回
归构建胰腺癌预后风险模型,搭配 GEO 数据库和本中心胰腺癌病例的基因表达和临床数据验证该模型的准确性与敏感性。
结果:筛选出CRLS1与C7orf50两个基因共同构成风险模型,本研究系统验证了该模型有预测胰腺癌预后的显著效能,该模型
联合肿瘤突变负荷(tumor mutation burden,TMB)具有更强的预后预测能力。结论:该模型是预测胰腺癌患者预后的新工具。

[Abstract] Objective:To establish a new pancreatic cancer risk assessment model based on the differential expression of m1A⁃related
genes in multiple databases and clinical parameters,and provide theoretical basis for pancreatic cancer treatment and prognosis
analysis. Methods:Differential analysis of m1A⁃related genes was performed in the TCGA⁃GTEx database. Cox analysis and LASSO
regression were used to construct a pancreatic cancer prognosis risk model,and the accuracy and sensitivity of the model were verified
by gene expression and clinical data from the GEO database and pancreatic cancer cases in our center. Results:CRLS1 and C7orf50
were selected to form the risk model. The study systematically verified that the model had significant efficacy in indicating the
prognosis of pancreatic cancer,and the model combined with tumor mutation burden(TMB)had a stronger prognostic indication
ability. Conclusion:A new risk model is constructed to indicate the prognosis of pancreatic cancer patients.
