在个体化医疗时代,早期非小细胞肺癌(NSCLC)患者的辅助化疗(ACT)反应的预后和预测仍然很差。我们假设,细胞外基质(ECM)相关成分可能是更好的诊断和预后的潜在标志物,因为它们在1,943例原发性NSCLC肿瘤和303例正常肺组织中的差异表达。在这里,我们开发了一个29基因ECM相关的预后和预测指标(EPPI)。我们在多个独立的数据集中验证了EPPI风险评分系统的稳健性能,这些数据集共包括2,071例早期NSCLC肿瘤。当应用于临床环境时,根据基于EPPI的通用截止评分对患者进行分层;低风险组的生存结局明显更好。功能性EPPI基因集代表了一种潜在的基因组工具,可改善早期NSCLC患者的选择,以进一步获得ACT的最佳获益,并预防不必要的治疗或ACT相关的发病率。非小细胞肺癌辅助化疗反应的预后和预测具有重要的临床意义。在这里,作者表明,差异表达的29细胞外基质基因指标,EPPI,可以预测患者的结果。
The prognosis and prediction of adjuvant chemotherapy (ACT) response in early-stage non-small cell lung cancer (NSCLC) patients remain poor in this era of personalized medicine. We hypothesize that extracellular matrix (ECM)-associated components could be potential markers for better diagnosis and prognosis due to their differential expression in 1,943 primary NSCLC tumors as compared to 303 normal lung tissues. Here we develop a 29-gene ECM-related prognostic and predictive indicator (EPPI). We validate a robust performance of the EPPI risk scoring system in multiple independent data sets, comprising a total of 2,071 early-stage NSCLC tumors. Patients are stratified according to the universal cutoff score based on the EPPI when applied in the clinical setting; the low-risk group has significantly better survival outcome. The functional EPPI gene set represents a potential genomic tool to improve patient selection in early-stage NSCLC to further derive the best benefits of ACT and prevent unnecessary treatment or ACT-associated morbidity. Prognosis and prediction of adjuvant chemotherapy response in non-small cell lung cancer can have significant clinical impact. Here, the authors show that differential expression of a 29 extracellular matrix gene indicator, EPPI, can predict patient outcome.
