Title: PRIME: Prototype-Driven Multimodal Pretraining for Cancer Prognosis with Missing Modalities

Abstract:
arXiv:2604.04999v1 Announce Type: cross Abstract: Multimodal self-supervised pretraining offers a promising route to cancer prognosis by integrating histopathology whole-slide images, gene expression, and pathology reports, yet most existing approaches require fully paired and complete inputs. In practice, clinical cohorts are fragmented and often miss one or more modalities, limiting both supervised fusion and scalable multimodal pretraining. We propose PRIME, a missing-aware multimodal self-su
