In gynecological oncology, ovarian cancer (OC) remains the most lethal, highlighting its significance in public health. Our research focused on the role of long non-coding RNA (lncRNA) in OC, particularly senescence-related lncRNAs (SnRlncRNAs), crucial for OC prognosis. Utilizing data from the genotype-tissue expression (GTEx) and cancer genome Atlas (TCGA), SnRlncRNAs were discerned and subsequently, a risk signature was sculpted using co-expression and differential expression analyses, Cox regression, and least absolute shrinkage and selection operator (LASSO). This signature's robustness was validated through time-dependent receiver operating characteristics (ROC), and multivariate Cox regression, with further validation in the international cancer genome consortium (ICGC). Gene set enrichment analyses (GSEA) unveiled pathways intertwined with risk groups. The ROC, alongside the nomogram and calibration outcomes, attested to the model's robust predictive accuracy. Of particular significance, our model has demonstrated superiority over several commonly utilized clinical indicators, such as stage and grade. Patients in the low-risk group demonstrated greater immune infiltration and varied drug sensitivities compared to other groups. Moreover, consensus clustering classified OC patients into four distinct groups based on the expression of 17 SnRlncRNAs, showing diverse survival rates. In conclusion, these findings underscored the robustness and reliability of our model and highlighted its potential for facilitating improved decision-making in the context of risk assessment, and demonstrated that these markers potentially served as robust, efficacious biomarkers and prognostic tools, offering insights into predicting OC response to anticancer therapeutics.

在妇科肿瘤学中,卵巢癌(OC)仍然是最致命的,凸显了其在公共卫生中的重要性。我们的研究聚焦于长链非编码RNA(lncRNA)在OC中的作用,特别是衰老相关lncRNA(SnRlncRNAs),其对OC预后至关重要。利用基因型-组织表达(GTEx)和癌症基因组图谱(TCGA)的数据,识别出SnRlncRNAs,随后通过共表达和差异表达分析、Cox回归以及最小绝对收缩和选择算子(LASSO)构建了一个风险特征。通过时间依赖的受试者工作特征(ROC)和多变量Cox回归验证了该特征的稳健性,并在国际癌症基因组联盟(ICGC)中进一步验证。基因集富集分析(GSEA)揭示了与风险组相关的通路。ROC以及列线图和校准结果证明了该模型具有强大的预测准确性。特别值得注意的是,我们的模型已证明优于几个常用的临床指标,如分期和分级。与其他组相比,低风险组患者表现出更强的免疫浸润和不同的药物敏感性。此外,共识聚类根据17种SnRlncRNAs的表达将OC患者分为四个不同的组,显示出不同的生存率。总之,这些发现强调了我们模型的稳健性和可靠性,并突出了其在风险评估背景下促进改善决策的潜力,证明这些标志物有可能作为强大、有效的生物标志物和预后工具,为预测OC对抗癌治疗的反应提供见解。
