Abstract

Accurate prediction of 1p/19q status is important for glioma diagnosis and prognosis. Existing deep learning methods usually treat 1p/19q codeletion prediction as a binary classification task, ignoring the individual deletion status of 1p and 19q. In this paper, we propose D2TMIL, a disentangled dual-task multiple instance learning framework for 1p/19q status prediction from whole-slide histopathological images. The proposed method decomposes codeletion prediction into two subtasks, 1p deletion prediction and 19q deletion prediction, and estimates the final codeletion probability through their joint distribution. A dual-task cross-attention module and a mutual-information dual-task coupling module are introduced to enhance cross-task feature interaction and model task correlations. Experiments on a glioma dataset show that D2TMIL outperforms baseline methods in both single-arm deletion prediction and 1p/19q codeletion prediction.
