Renal cell carcinoma (RCC) is associated with poor prognostic outcomes. The current stratifying system does not predict prognostic outcomes and therapeutic benefits precisely for RCC patients. Here, we aim to construct an immune prognostic predictive model to assist clinician to predict RCC prognosis.
Herein, an immune prognostic signature was developed, and its predictive ability was confirmed in the kidney renal clear cell carcinoma (KIRC) cohorts based on The Cancer Genome Atlas (TCGA) dataset. Several immunogenomic analyses were conducted to investigate the correlations between immune risk scores and immune cell infiltrations, immune checkpoints, cancer genotypes, tumor mutational burden, and responses to chemotherapy and immunotherapy.
The immune prognostic signature contained 14 immune-associated genes and was found to be an independent prognostic factor for KIRC. Furthermore, the immune risk score was established as a novel marker for predicting the overall survival outcomes for RCC. The risk score was correlated with some significant immunophenotypic factors, including T cell infiltration, antitumor immunity, antitumor response, oncogenic pathways, and immunotherapeutic and chemotherapeutic response.
The immune prognostic, predictive model can be effectively and efficiently used in the prediction of survival outcomes and immunotherapeutic responses of RCC patients.
肾细胞癌(RCC)与不良预后相关。目前的分层系统不能准确预测 RCC 患者的预后结果和治疗获益。在这里,我们旨在构建一个免疫预后预测模型,以帮助临床医生预测 RCC 的预后。
本研究中,我们开发了一个免疫预后特征,并基于癌症基因组图谱(TCGA)数据集在肾透明细胞癌(KIRC)队列中验证了其预测能力。进行了几项免疫基因组学分析,以研究免疫风险评分与免疫细胞浸润、免疫检查点、癌症基因型、肿瘤突变负担以及对化疗和免疫治疗的反应之间的相关性。
免疫预后特征包含 14 个与免疫相关的基因,被发现是 KIRC 的独立预后因素。此外,免疫风险评分被确定为预测 RCC 总体生存结果的新型标志物。风险评分与一些重要的免疫表型因素相关,包括 T 细胞浸润、抗肿瘤免疫、抗肿瘤反应、致癌途径以及免疫治疗和化疗反应。
免疫预后、预测模型可有效地用于预测 RCC 患者的生存结果和免疫治疗反应。
