针对有创乳腺癌分级的痛点,本研究融合优化后的CDI^s与DWI构建多参数MRI,基于更大患者队列微调全层预训练MONAI模型,将分级预测的留一法交叉验证准确率提升至95.79%,较此前结果高8%以上。

摘要:

2015年至2020年间,有超过780万名女性被诊断出患有乳腺癌。分级在乳腺癌治疗方案规划中起着至关重要的作用。然而,当前的肿瘤分级方法需要从患者体内提取组织,会给患者带来压力与不适,且医疗成本高昂。近期一篇研究利用合成相关扩散成像(CDI$^s$)的体积深度影像组学特征进行乳腺癌分级预测,展现出无创分级方法的巨大潜力。受CDI$^s$优化对前列腺癌勾画的增益效果启发,本文探究了使用优化后的CDI$^s$改进乳腺癌分级预测的效果。我们将优化后的CDI$^s$信号与弥散加权成像(DWI)融合,为每位患者构建多参数MRI。本研究采用了更大的患者队列,并对预训练MONAI模型的所有层进行训练,最终留一法交叉验证准确率达到95.79%,较此前报道的结果高出8%以上。

英文摘要:

Breast cancer was diagnosed for over 7.8 million women between 2015 to 2020. Grading plays a vital role in breast cancer treatment planning. However, the current tumor grading method involves extracting tissue from patients, leading to stress, discomfort, and high medical costs. A recent paper leveraging volumetric deep radiomic features from synthetic correlated diffusion imaging (CDI$^s$) for breast cancer grade prediction showed immense promise for noninvasive methods for grading. Motivated by the impact of CDI$^s$ optimization for prostate cancer delineation, this paper examines using optimized CDI$^s$ to improve breast cancer grade prediction. We fuse the optimized CDI$^s$ signal with diffusion-weighted imaging (DWI) to create a multiparametric MRI for each patient. Using a larger patient cohort and training across all the layers of a pretrained MONAI model, we achieve a leave-one-out cross-validation accuracy of 95.79%, over 8% higher compared to that previously reported.
