28th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) 2025 Conference
This paper presents a Multimodal Representation Decoupling Network (MurreNet) to advance cancer survival analysis. Specifically, we first propose a Multimodal Representation Decomposition (MRD) module to explicitly decompose paired input data into modality-specific and modality-shared representations, thereby reducing redundancy between modalities. Furthermore, the disentangled representations are further refined then updated through a novel training regularization strategy that imposes constraints on distributional similarity, difference, and representativeness of modality features. Finally, the augmented multimodal features are integrated into a joint representation via proposed Deep Holistic Orthogonal Fusion (DHOF) strategy. Extensive experiments conducted on six TCGA cancer cohorts demonstrate that our MurreNet achieves state-of-the-art (SOTA) performance in survival prediction.

IEEE Transactions on Medical Imaging 2024 Journal
This study proposed HGPT, a novel framework that jointly considers geometric and global representation for cancer diagnosis in histopathological images. HGPT leverages a multi-head graph aggregator to aggregate the geometric representation from pathological morphological features, and a locality feature enhancement block to highly enhance the 2D local feature perception in vision transformers, leading to improved performance on histopathological image classification. Extensive experiments on Kather-5K, MHIST, NCT-CRC-HE, and GasHisSDB four public datasets demonstrate the advantages of the proposed HGPT over bleeding-edge approaches in improving cancer diagnosis performance.

We proposed a novel weakly-supervised framework, Geometry-Aware Transformer (GOAT), in which we urge the model to pay attention to the geometric characteristics within the tumor microenvironment which often serve as potent indicators. In addition, a context-aware attention mechanism is designed to extract and enhance the morphological features within WSIs. Extensive experimental results demonstrated that the proposed method is capable of consistently reaching superior classification outcomes for gigapixel whole slide images.

We propose the Mutual-Guided Cross-Modality Transformer (MGCT), a weakly-supervised, attention-based multimodal learning framework that can combine histology features and genomic features to model the genotype-phenotype interactions within the tumor microenvironment. Extensive experimental results on five benchmark datasets consistently emphasize that MGCT outperforms the state-of-the-art (SOTA) methods.
