Abstract

Integrating histopathology with genetic/omics tabular data is central to computational oncology, yet most multimodal models simply concatenate image and gene features and never learn the biological correspondence between them. We introduce JPathGene, a cross-modal joint-embedding predictive framework that formulates image–genetic fusion as latent prediction. A single predictor unifies within-modality masked prediction (I-JEPA) and cross-modal prediction; because one tissue phenotype is compatible with a distribution of genetic programs, a conditional latent-diffusion predictor models that distribution (deterministic JEPA being its single-step limit) and yields a per-patient cross-modal uncertainty. CoRE-Fusionuses that uncertainty to gate an image expert that corrects a genomic anchor, weighting histology by its cross-modal reliability, without decoding raw expression. On a leakage-safe TCGA-BRCA benchmark with UNI2-h features, JPathGene achieves the highest multimodal AUC: it ties a strong but over-confident gene-only baseline on AUC while being significantly better calibrated (p<0.001) and best on proper scoring rules. On TCGA-LUAD, CoRE significantly beats gene-only on both AUC and calibration on a molecular endpoint, while on a non-saturated anatomic stage endpoint fusion adds large discrimination (+0.07 to +0.11 AUC). The benefit is thus contingent on feature quality and on whether genomics already saturates the endpoint. All code and models will be publicly available in our official repository: https://github.com/JianJiaXian/JPathGene.
