研究目的:

非小细胞肺癌(NSCLC)是全球癌症相关死亡的首要原因,新辅助免疫治疗已成为可切除NSCLC的重要治疗手段,显著改善了部分患者的预后。但当前基于主要病理缓解(MPR)的评估标准存在局限,约20%的MPR患者仍会在3年内复发,且放射学评估误判率较高,同时缺乏无创、实时的疗效监测工具,难以早期识别无应答患者并及时调整治疗策略。呼出气中的挥发性有机化合物(VOCs)作为机体代谢活动的重要指标,其谱图变化与肿瘤代谢及治疗反应密切相关,为无创疗效预测提供了新思路。本研究为非干预、观察性临床研究,仅采集受试者治疗前、治疗中及术前的呼出气样本,不干预临床诊疗流程。通过自主研发的高气压光子电离-飞行时间质谱(HPPI-TOFMS)平台检测VOCs谱,筛选与治疗应答相关的差异标志物,构建并验证新辅助免疫治疗疗效预测模型,同时探索VOCs谱动态变化轨迹,确立早期评估关键时间点,为临床精准治疗决策提供无创、便捷的技术支持。  

Objectives of Study:

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths worldwide. Neoadjuvant immunotherapy has become a crucial treatment approach for resectable NSCLC, significantly improving the prognosis of some patients. However, current evaluation standards based on major pathological response (MPR) have limitations, as approximately 20% of patients with MPR still experience recurrence within three years. Radiological assessment also suffers from a high misjudgment rate, and there is a lack of non-invasive, real-time tools for monitoring treatment efficacy, making it difficult to identify non-responders early and adjust treatment strategies promptly. Volatile organic compounds (VOCs) in exhaled breath, as important indicators of metabolic activity in the body, exhibit profile changes closely related to tumor metabolism and treatment response, offering a novel approach for non-invasive efficacy prediction. This study is a non-interventional, observational clinical trial. It only collects exhaled breath samples from participants before treatment, during treatment, and before surgery, without interfering with clinical diagnosis and treatment procedures. Using a self-developed high-pressure photon ionization time-of-flight mass spectrometry (HPPI-TOFMS) platform, VOCs profiles are analyzed to identify differential biomarkers associated with treatment response. The study aims to construct and validate a predictive model for the efficacy of neoadjuvant immunotherapy
