摘要:

模型表达其自身预测不确定性的能力是维持临床用户信心的基本属性,因为计算生物标志物被部署到现实世界的医疗环境中。在癌症数字组织病理学领域,我们描述了一种新的,面向临床的方法,用于全切片图像的不确定性量化(UQ),使用dropout估计不确定性,并计算训练数据的阈值,以建立低置信度和高置信度预测的截止值。我们训练模型来识别肺腺癌与鳞状细胞癌,并表明高置信度预测在交叉验证和跨多个机构的两个大型外部数据集的测试中优于没有UQ的预测。我们的测试策略非常接近真实世界的应用程序,使用预定阈值在无监督、无注释的幻灯片上生成预测。此外,我们表明,UQ阈值在域转移的设置中仍然是可靠的,对于分布外的非肺癌队列,腺癌与鳞状细胞癌具有准确的高置信度预测。

英文摘要:

A model's ability to express its own predictive uncertainty is an essential attribute for maintaining clinical user confidence as computational biomarkers are deployed into real-world medical settings. In the domain of cancer digital histopathology, we describe a novel, clinically-oriented approach to uncertainty quantification (UQ) for whole-slide images, estimating uncertainty using dropout and calculating thresholds on training data to establish cutoffs for low- and high-confidence predictions. We train models to identify lung adenocarcinoma vs. squamous cell carcinoma and show that high-confidence predictions outperform predictions without UQ, in both cross-validation and testing on two large external datasets spanning multiple institutions. Our testing strategy closely approximates real-world application, with predictions generated on unsupervised, unannotated slides using predetermined thresholds. Furthermore, we show that UQ thresholding remains reliable in the setting of domain shift, with accurate high-confidence predictions of adenocarcinoma vs. squamous cell carcinoma for out-of-distribution, non-lung cancer cohorts.
