Abstract

Endometrial cancer (EC) is the most common gynecologic malignancy in the United States. Hormone therapies and hysterectomy are viable treatments for early-stage EC and atypical endometrial hyperplasia (AEH), a high-risk precursor to EC. Prediction of patient response to hormonal treatment is useful for patients to make treatment decisions. We have previously developed a mix-supervised model: a weakly supervised deep learning model for hormonal treatment response prediction based on pathologist-annotated AEH and EC regions on whole slide images of H&E stained slides. The reliance on pathologist annotation in applying the model to new cases is cumbersome and subject to inter-observer variability. In this study, we automate the task of ROI detection by developing a supervised deep learning model to detect AEH and EC regions. This model achieved a patch-wise AUROC performance of 0.974 (approximate 95% CI [0.972, 0.976]). The mixsupervised model yielded a patient-level AUROC of 0.76 (95% CI [0.59, 0.92]) with ROIs detected by our new model on a hold-out test set in the task of classifying patients into responders and non-responders. As a comparison, the original model as tested on pathologist-annotated ROIs achieved an AUROC of 0.80 with 95% CI [0.63, 0.95]. Our results demonstrate the potential of using weakly supervised deep learning and supervised ROI detection model for predicting hormonal treatment response in endometrial cancer patients.
