ChronoSurv: A Clinical Pathway-Guided Graph Framework for Multimodal Survival Analysis

arXiv:2606.19140v1 Announce Type: new Abstract: Accurate survival prediction is essential for personalized treatment planning in head and neck cancer, yet remains challenging due to the heterogeneous and high-dimensional nature of multimodal clinical data. While deep survival models have improved predictive performance over classical statistical approaches, existing methods typically rely on static fusion strategies or temporally agnostic modeling, limiting their ability to capture structured clinical workflows. In this work, we propose ChronoSurv, a heterogeneous hierarchical directed graph f

Why this matters
Why now

The proliferation of multimodal clinical data and advancements in graph neural networks are enabling more sophisticated approaches to patient-specific survival prediction.

Why it’s important

Improved predictive models for cancer survival directly inform personalized treatment strategies, potentially enhancing patient outcomes and healthcare efficiency.

What changes

This work introduces a more dynamic and clinically pathway-guided approach to survival analysis, moving beyond static fusion methods to better represent temporal clinical workflows.
