Predicting Lung Cancer Survival with Attention-Based CT Slices Combination

This research introduces a novel deep learning methodology for predicting 2-year overall survival (OS) in NSCLC patients from CT scans. By integrating EfficientNetB0 with a soft attention mechanism and a DeepHit risk-assessment network, we overcome challenges of computational complexity and data limitations, achieving superior prognostic accuracy and enhanced interpretability.

Our approach outperforms conventional 3D networks, achieving a mean Ctd-index of 0.584 on the LUNG1 dataset. Furthermore, transfer learning significantly boosts performance in limited data scenarios, demonstrating robust generalization.

Impact on Clinical Prognosis & Operational Efficiency

Leveraging attention-based insights from CT scans, our AI model provides clinicians with a powerful tool for more accurate and timely lung cancer prognosis, improving treatment planning and patient outcomes while optimizing resource utilization.

Proposed Survival Prediction Workflow

Our innovative methodology streamlines lung cancer survival prediction by intelligently processing CT scan data through a series of specialized AI stages.

Import & Interpolation (1,1,3 mm voxels)
Area Filtering (>2% lung area slices)
ROI Extraction (lungs bounding box)
Resize (224x224 pixels)
EfficientNetB0 (slice representations)
Soft Attention Mechanism (weighting relevant slices)
Volume Representation (3D feature vector)
DeepHit Risk Assessment (OS Prediction)
0.584 Peak Ctd-index Achieved on LUNG1

Our attention-based approach significantly outperforms all 3D baselines, establishing a new benchmark for 2-year OS prediction.

Feature Proposed Method (EfficientNetB0 + Soft Attention) 3D Baselines (ResNet3D, DenseNet3D, MST)
Architectural Approach
  • 2D CNN (EfficientNetB0) with Soft Attention, lower parameters.
  • Full 3D CNNs (ResNet3D, DenseNet3D) or MST, higher complexity.
Generalization for Limited Data
  • Superior generalization, especially with feature extractor strategy, less overfitting.
  • Limited generalization with small datasets, prone to overfitting.
Computational Cost
  • Significantly lower GFLOPS and parameter count.
  • Higher computational demands for processing volumetric data.
Temporal Dynamics
  • DeepHit integrates time-dependent risk assessment, handles censored data.
  • Often focuses on fixed time points, less dynamic.

Robustness & Transferability: CLARO Dataset

Our model's ability to adapt and perform well on new, limited datasets like CLARO, after pretraining on LUNG1, underscores its strong generalizability and the critical role of domain-specific transfer learning.

  • Direct Application (LUNG1 pretrained, no fine-tune on CLARO): Ctd-index of 0.5608, showing learned representations retain prognostic relevance.
  • Training From Scratch (CLARO): Average Ctd-index 0.503 ± 0.017.
  • Transfer Learning (LUNG1 pretrained, fine-tune on CLARO): Average Ctd-index 0.577 ± 0.021.
  • Statistical Significance: Wilcoxon signed-rank test confirmed significant difference (p < 0.05, large effect size r ≈ 0.899).

Attention-Based Interpretability for Clinical Insights

The soft attention mechanism provides valuable interpretability by highlighting CT slices most relevant for prognosis, aligning with clinical evidence and enhancing trust.

  • Focus on Basal Regions: Model consistently assigns higher attention weights to basal lung regions, aligning with clinical evidence for worse outcomes.
  • Enhanced Decision-Making: Provides a transparent window into the model's predictions, aiding clinicians in understanding prognostic factors.
  • Example Patient (LUNG1-040): Tumor in lower slices (stage III NSCLC) with corresponding high attention, and observed survival time (19 months) aligns with predicted death probability (0.61), validating the model's clinical relevance.
