目的
2
构建基于CT影像组学的胰腺导管腺癌(pancreatic ductal adenocarcinoma,PDAC)预后预测模型,为个体化治疗决策提供依据。
方法
2
回顾性纳入2020年1月至2023年12月在陆军军医大学第一附属医院就诊的118例PDAC患者,按7∶3比例将患者分为训练组(
n
=83)和验证组(
n
=35)。采用ITK-SNAP软件对术前增强CT动脉期图像进行3D分割,通过pyradiomics提取影像组学特征。经ICC分析(
>
0.85)筛选高重复性特征,采用LASSO回归确定核心特征并构建Rad-score。基于Cox回归分析构建影像组学模型及联合临床特征的综合模型,用于预测PDAC患者总生存时间。采用受试者工作特征(ROC)曲线及校准曲线对模型进行评价。
结果
2
共提取1 453个影像组学特征,经筛选最终确定7个核心特征构建Rad-score。基于Rad-score构建的影像组学预测模型在训练组和验证组的1年生存预测AUC分别为0.796(95%
CI
:0.702~0.890)和0.744(95%
CI
:0.589~0.899)。联合临床特征的综合预测模型分别为0.906(95%
CI
:0.842~0.970)和0.872(95%
CI
:0.753~0.992)。校准曲线显示模型具有良好的预测准确性
。
结论
2
基于CT影像特征构建的影像组学模型和联合临床特征的综合预测模型具有良好的生存时间预测效能。
Objective To develop a CT radiomics-based prediction model for prognosis of pancreatic ductal adenocarcinoma (PDAC) in order to provide evidence for individualized treatment decisions.
Methods
2
A retrospective study was carried on 118 PDAC patients admitted in the First Affiliated Hospital of Army Medical University between January 2020 and December 2023. They were assigned into a training group (
n
=83) and a validation group (
n
=35) at a 7∶3 ratio. ITK-SNAP software was used to perform 3-D segmentation on the preoperatively enhanced arterial phase CT images
and radiomic features were extracted using pyradiomics. High-reproducibility features were selected through ICC analysis (
>
0.85)
and core features were determined using LASSO regression to construct the Rad-score. Cox regression analysis was employed to develop both a radiomics model and a model integrating radiomic and clinical features for predicting overall survival in PDAC patients. Receiver operating characteristic (ROC) curves and calibration curves were plotted to evaluate the prognostic models for survival prediction.
Results
2
From 1 453 extracted radiomic features
7 core features were finally selected to construct the Rad-score. The radiomics prediction model based on the Rad-score achieved an AUC value of 0.796 (95%
CI
: 0.702~0.890) and 0.744 (95%
CI
: 0.589~0.899) for 1-year survival prediction in the training and validation groups
respectively. The integrated model combining 2 types of features together demonstrated improved performance with an AUC value of 0.906 (95%
CI
: 0.842~0.970) and 0.872 (95%
CI
: 0.753~0.992) in the 2 groups. Calibration curve analysis indicated good prediction accuracy for both models.
Conclusion
2
Both the CT radiomics-based model and the integrated model incorporating clinical features demonstrate good predictive performance for survival outcomes.
