FA-DeepMSM: a few-shot adapted interpretable multimodal survival model for improved prognostic prediction in glioblastoma
Survival prediction in IDH-wildtype glioblastoma is an inherently time-dependent challenge. FA-DeepMSM, a few-shot adapted interpretable multimodal survival model, integrates self-supervised MRI features with clinical and molecular variables to address data scarcity, cross-modal misalignment, and limited interpretability. It improves generalization (C-index from 0.643 to 0.680) and provides time-resolved interpretability. Early prognosis is driven by extent of resection, while later phases are influenced by MGMT promoter methylation and image-derived features, establishing a scalable and explainable paradigm.
Revolutionizing Glioblastoma Prognosis with AI
FA-DeepMSM represents a significant leap in neuro-oncology, offering a robust and interpretable AI solution for glioblastoma survival prediction. Its ability to generalize across diverse clinical settings with minimal data makes it exceptionally valuable for personalized treatment planning and clinical trial design.

| Model | Average C-index (95% CI) |
|---|---|
| DeepMSM (Multimodal) | 0.788 (0.782–0.793) |
| DeepMSM (Clinical-only) | 0.749 (0.742–0.755) |
| DeepMSM (Image-only) | 0.697 (0.692–0.702) |
| CoxPH (Multimodal) | 0.760 (0.753–0.767) |
| RSF (Multimodal) | 0.771 (0.767–0.775) |
Patient-Level Interpretability in Practice
The model provides patient-specific survival predictions and Grad-CAM visualizations. For example, Patient 1 (72-year-old male, GBM, WHO grade 4, KPS 100, MGMT un-methylated, non-total EOR) died at 22 months with a predicted survival probability of 0.109. Patient 2 (62-year-old male, WHO grade 3, KPS 90, MGMT un-methylated, non-total EOR) died at 95 months with a predicted survival probability of 0.06. This illustrates the model's ability to differentiate risk based on diverse clinical and imaging features, with activation maps aligning with tumor boundaries.
Key Takeaways:
- Grad-CAM visualizes regions contributing most to predicted survival risk, aligning with tumor lesions.
- Individualized survival curves differentiate patients with distinct clinical outcomes.
- Model leverages clinically relevant features for accurate predictions.
