BACKGROUND
Adjuvant epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) show promising outcomes in early-stage non-small cell lung cancer (NSCLC) with EGFR mutations, but accurately identifying patients who would derive the greatest benefit remains a clinical challenge. We compared the predictive performance of clinicopathological factors and the 14-gene assay to assess postoperative prognosis and predict the potential benefit of adjuvant EGFR-TKIs in stage I NSCLC.
METHODS
From March 2013 to February 2019, patients with completely resected stage I NSCLC [8th edition tumor-node-metastasis (TNM) classification staging] and EGFR mutation were included. The 14-gene assay, assessed through quantitative reverse transcription polymerase chain reaction (qPCR), was developed and subsequently validated across diverse international cohorts. Clinicopathological high-risk factors included any feature indicating a higher risk of recurrence based on the National Comprehensive Cancer Network (NCCN) guidelines. The primary endpoint of this study was the 5-year disease-free survival (DFS) rate.
RESULTS
Diagnostic values were evaluated in 180 stage I NSCLC patients. The 14-gene assay demonstrated superior performance compared to clinicopathological factors in predicting recurrence events. Patients with molecular high-risk, rather than clinicopathological high-risk factors, showed a more favorable response to adjuvant EGFR-TKIs. Specifically, adjuvant EGFR-TKIs benefited molecular high-risk patients, regardless of clinicopathological high-risk (DFS rate increased from 65.9% to 95.0%, P=0.02) or low-risk subgroups (80.0% to 100%, P=0.04). Patients with molecular low risk did not show any benefit from EGFR-TKIs, regardless of clinicopathological high-risk (DFS rate increased from 93.3% to 100%, P=0.37) or low-risk subgroups (97.0% to 100%, P=0.73).
CONCLUSIONS
The 14-gene assay is proven to be superior to clinicopathological factors, offering valuable guidance for adjuvant EGFR-TKIs decisions in stage I NSCLC.
背景
辅助性表皮生长因子受体酪氨酸激酶抑制剂（EGFR-TKIs）在伴有EGFR突变的早期非小细胞肺癌（NSCLC）中显示出有前景的疗效，但准确识别能从治疗中获得最大益处的患者仍是一项临床挑战。我们比较了临床病理因素和14基因检测在评估I期NSCLC术后预后及预测辅助性EGFR-TKIs潜在获益方面的预测性能。
方法
纳入2013年3月至2019年2月期间完全切除的I期NSCLC（第8版肿瘤-淋巴结-转移（TNM）分类分期）且伴有EGFR突变的患者。通过定量逆转录聚合酶链反应（qPCR）评估的14基因检测方法已开发完成，并随后在不同国际队列中进行了验证。临床病理高危因素包括基于美国国立综合癌症网络（NCCN）指南提示复发风险较高的任何特征。本研究的主要终点是5年无病生存率（DFS）。
结果
对180例I期NSCLC患者的诊断价值进行了评估。在预测复发事件方面，14基因检测显示出优于临床病理因素的性能。分子高危而非临床病理高危因素的患者对辅助性EGFR-TKIs表现出更良好的反应。具体而言，辅助性EGFR-TKIs使分子高危患者获益，无论其临床病理为高危（DFS率从65.9%提高到95.0%，P=0.02）还是低危亚组（从80.0%提高到100%，P=0.04）。分子低危患者未显示从EGFR-TKIs中获得任何益处，无论其临床病理为高危（DFS率从93.3%提高到100%，P=0.37）还是低危亚组（从97.0%提高到100%，P=0.73）。
结论
14基因检测被证明优于临床病理因素，为I期NSCLC辅助性EGFR-TKIs治疗决策提供了有价值的指导。
