目的 探究自噬相关基因在肾细胞癌发展中的作用,基于自噬相关的基因及CT影像特点构建肾细胞癌患者预后模型。方法 从TCGA数据库下载肾透明细胞癌患者相关资料,结合自噬相关基因集,探索基于自噬相关基因的肾癌分子亚型及构建个体化自噬评分系统;通过分析TCIA数据库中肾细胞癌患者CT资料,构建自噬相关基因风险模型及影像组学模型预测肾癌患者预后。结果 将肾透明细胞癌分为两种新的分子亚型,预后较差的亚型患者伴有大量免疫细胞浸润(P<0。05),且临床分级更高、分期更晚(P<0。05)。高自噬评分患者的肿瘤基因突变频率明显增加、肿瘤体积更大、更晚期、预后更差(P<0。05)。影像组学联合自噬相关基因模型可较准确预测肾癌患者预后(曲线下面积0。922,95%CI:0。852~0。993)。结论 自噬评分高的肾癌患者预后较差,影像组学联合自噬相关基因模型在预测肾癌患者预后中有较好前景。
Construction of a prognostic model for renal cell carcinoma patients based on autophagy-related genes and CT imaging characteristics
Objective To explore the role of autophagy-related genes in the development of renal cell carcinoma and construct a prognostic model for renal cell carcinoma patients based on autophagy-related genes and CT imaging characteristics.Methods The relevant data of patients with renal clear cell carcinoma were downloaded from the TCGA database.Combined with the autophagy-related gene set,the molecular subtypes of renal carcinoma based on autophagy-related genes and the construction of an individualized autophagy scoring system were explored;by analyzing the CT data of patients with renal cell carcinoma in the TCIA database,the autophagy-related gene risk model and the imaging omics model were constructed to predict the prognosis of patients with renal cancer.Results Renal clear cell carcinoma was divided into two new molecular subtypes.Patients with poor prognosis are accompanied by a large number of immune cell infiltration(P<0.05),and have higher clinical grades and more advanced stages(P<0.05).Patients with high autophagy scores have significantly increased tumor gene mutation frequencies,larger tumor volumes,more advanced stages,and worse prognoses(P<0.05).Radiomics combined with autophagy-related gene model can accurately predict the prognosis of patients with renal cancer(AUC:0.922,95%CI:0.852-0.993).Conclusion Renal cancer patients with high autophagy scores have a poor prognosis.Radiomics combined with autophagy-related gene model has good prospects in predicting the prognosis of patients with renal cancer.
