- Abstract
Objectives: To establish a deep learning (DL) model for predicting tumor grades and expression of pathologic markers of meningioma. Methods: A total of 1192 meningioma patients from two centers who underwent surgical resection between September 2018 and December 2021 were retrospectively included. The pathological data and post-contrast T1-weight images for each patient were collected. The patients from institute I were subdivided into training, validation, and testing sets, while the patients from institute II served as the external testing cohort. The fine-tuned ResNet50 model based on transfer learning was adopted to classify WHO grade in the whole cohort and predict Ki-67 index, H3K27me3, and progesterone receptor (PR) status of grade 1 meningiomas. The predictive performance was evaluated by the accuracy and loss curve, confusion matrix, receiver operating characteristic curve (ROC), and area under curve (AUC). Results: The DL prediction model for each label achieved high predictive performance in two cohorts. For WHO grade prediction, the area under the curve (AUC) was 0.966 (95%CI 0.957–0.975) in the internal testing set and 0.669 (95%CI 0.643–0.695) in the external validation cohort. The AUC in predicting Ki-67 index, H3K27me3, and PR status were 0.905 (95%CI 0.895–0.915), 0.773 (95%CI 0.760–0.786), and 0.771 (95%CI 0.750–0.792) in the internal testing set and 0.591 (95%CI 0.562–0.620), 0.658 (95%CI 0.648–0.668), and 0.703 (95%CI 0.674–0.732) in the external validation cohort, respectively. Conclusion: DL models can preoperatively predict meningioma grades and pathologic marker expression with favorable predictive performance. Clinical relevance statement: Our DL model could predict meningioma grades and expression of pathologic markers and identify high-risk patients with WHO grade 1 meningioma, which would suggest a more aggressive operative intervention preoperatively and a more frequent follow-up schedule postoperatively. Key Points: WHO grades and some pathologic markers of meningioma were associated with therapeutic strategies and clinical outcomes. A deep learning–based approach was employed to develop a model for predicting meningioma grades and the expression of pathologic markers. Preoperative prediction of meningioma grades and the expression of pathologic markers was beneficial for clinical decision-making.
