Cervical cancer is one of the most common types of gynecological malignancies worldwide. This study aims to develop an immune signature to predict survival in cervical cancer.
The gene expression data of 296 patients with cervical cancer from The Cancer Genome Atlas database (TCGA) and immune-related genes from the Immunology Database and Analysis Portal () database were included in this study. The immune signature was developed based on prognostic genes. The validation dataset was downloaded from the Gene Expression Omnibus (GEO) database.
The immune signature namely immune-based prognostic score (IPRS) was developed with 229 genes. Multivariate analysis revealed that the IPRS was an independent prognostic factor for overall survival (OS) and progression-free survival (PFS) in patients with cervical cancer. Patients were stratified into high IPRS and low IPRS groups, and those in the high IPRS group were associated with better survival, which was validated in the validation set. A nomogram with IPRS and stage was constructed to predict mortality in cervical cancer.
We developed a robust prognostic signature IPRS that could be used to predict patients' survival outcome.
宫颈癌是全球最常见的妇科恶性肿瘤类型之一。本研究旨在开发一种免疫特征以预测宫颈癌患者的生存情况。
本研究纳入了来自癌症基因组图谱数据库(TCGA)的296例宫颈癌患者的基因表达数据以及来自免疫学数据库和分析门户(ImmPort)数据库的免疫相关基因。基于预后基因开发免疫特征。验证数据集从基因表达综合数据库(GEO)下载。
利用229个基因开发了免疫特征,即基于免疫的预后评分(IPRS)。多变量分析显示,IPRS是宫颈癌患者总生存期(OS)和无进展生存期(PFS)的独立预后因素。患者被分为高IPRS组和低IPRS组,高IPRS组患者的生存期更好,这在验证集中得到了验证。构建了一个包含IPRS和分期的列线图以预测宫颈癌患者的死亡率。
我们开发了一种可靠的预后特征IPRS,可用于预测患者的生存结局。
