研究目的:

本研究提出基于机器学习,利用肺癌患者的临床资料、影像组学和病理组学数据构建临床预测模型,协助临床工作者在免疫治疗前准确识别CIP高危患者,期望协助指导临床用药,提升对CIP的及时治疗能力,对于改善肺癌患者预后、提高生存率有重要的意义。  

Objectives of Study:

This study proposes a machine learning-based approach that utilizes clinical data, radiomics, and pathomics data of lung cancer patients to develop a clinical predictive model. The model aims to assist clinicians in accurately identifying high-risk patients for checkpoint inhibitor pneumonitis before initiating immunotherapy, with the expectation of guiding clinical decisions and enhancing the ability for timely treatment of CIP. It holds significant implications for improving the prognosis and survival rates of lung cancer patients.

测量时间点:

模型构建完成后

测量方法:

在模型构建完成后,计算模型对每个样本的预测分数,将样本根据预测分数从高到低排序。此时,每个独特的预测分数都可以作为一个潜在的分类阈值,从最高分(最严格阈值)开始,逐步降低阈值。在每个阈值下计算该阈值对应的 TPR 和 FPR,这个(FPR, TPR)对就是ROC曲线上的一个点。将所有计算出的(FPR, TPR)点用线段连接起来,并计算这条折线下的面积作为AUC。

Measure time point of outcome:

completion of the model construction

Measure method:

Once the model has been constructed, calculate the prediction score for each sample, and rank the samples from highest to lowest based on their prediction scores. At this point, each unique prediction score can serve as a potential classification threshold. Starting from the highest score (the strictest threshold), gradually lower the threshold. For each threshold, calculate the corresponding TPR and FPR. This (FPR, TPR) pair represents a point on the ROC curve. Connect all the calculated (FPR,

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

通过提取入组受试者常规临床诊疗记录、免疫治疗前基线胸部CT图像、肿瘤HE病理切片获取这项研究的数据,研究者在整个监测期间根据原始病历记录中的信息输入到研究的记录表中。研究记录做任何更正时只能划线,旁注改后的数据,说明理由,由研究者签名并注明日期,不得擦涂、覆盖原记录。此外,原始诊疗数据不外送。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The data for this study were acquired by extracting routine clinical diagnostic and treatment records of enrolled subjects, baseline chest CT scans prior to immunotherapy, and H&E-stained pathological sections of tumors. Throughout the monitoring period, investigators entered the information from the source medical records into the study case report forms. Any corrections to the study records must be made by drawing a single line through the original entry, adding the amended data alongside, providing a reason for the change, and having the investigator sign and date the correction. The original record must not be erased or obscured. Furthermore, the original clinical data will not be transferred externally.
