Generalizability
Overview: Our innovative framework allows any neural network to stratify patients based on survival heterogeneity, irrespective of data modality. This is achieved by reformulating the multivariate logrank statistic into a differentiable optimization criterion, enabling direct optimization for prognostically distinct patient groups.
Real-World Impact: Applied to Multiple Myeloma (MM) patients using routine blood work, the model successfully identified three prognostically distinct risk groups. Post-hoc explainability revealed clinically meaningful features aligning with established disease biology and even outperformed the R-ISS standard in some aspects.
Imaging Insights: For Non-Small Cell Lung Cancer (NSCLC), our CNN model, trained on CT images, achieved significant survival separation. Explainability analyses revealed the model's focus on branching infiltrative tumor tissue and cardiac morphology, autonomously identifying key prognostic features without explicit annotations.
Versatility: The approach's robustness was confirmed through external validation on independent cohorts (GMMG-MM5 for MM, institutional data for NSCLC), demonstrating its generalizability across different clinical settings and data protocols, a known challenge in radiomics.

4
Years Median Survival (High-Risk MM)
High-risk MM patients (Cluster 0) identified by our model had a median survival of approximately 4 years, demonstrating clear stratification.
Uncovering Novel MM Prognostic Signatures
Our MM model successfully identified clinically meaningful patterns aligning with established disease biology. For instance, high β2m and Cr levels were associated with higher risk, while elevated Alb and Hb levels correlated with lower risk, without explicit prior knowledge of these factors. This autonomous feature discovery capability extends beyond established markers, leveraging the nuances of routine blood work to identify novel prognostic signatures.
0.57
C-index in NSCLC (CT Imaging)
The CNN model for NSCLC patients achieved a c-index of 0.57 on CT imaging data, demonstrating significant survival separation between risk groups.
Interpretable Imaging Biomarkers in NSCLC
Despite being trained without tumor annotations, the CNN autonomously focused on intrapulmonary regions containing tumor infiltrates. SHAP analyses revealed attention patterns on branching infiltrative tissue and cardiac vessels in high-risk patients, aligning with known aggressive disease and cardiovascular comorbidity. This demonstrates the model's ability to identify clinically relevant imaging features purely from survival outcomes.
