Treatment decision support for esophageal cancer based on PET/CT data using deep learning
EXECUTIVE IMPACT
This study introduces a novel hybrid deep learning architecture that integrates convolutional and transformer-based components for enhanced treatment decision support in esophageal cancer. It leverages PET/CT imaging data to capture complex, multi-scale spatial patterns, aiming to improve predictive accuracy and patient outcomes. The model's key innovations include a Convolutional Feature Extractor (CFE) with split-based residual blocks and a Multi-scale Pooling (MSP) module for comprehensive feature learning, significantly outperforming existing methods.

Methodology: Building a Hybrid Deep Learning Model
The proposed architecture integrates Convolutional Local Blocks (CLB) for local feature extraction, a Multi-scale Pooling (MSP) module for spatial context aggregation, and a Multilayer Perceptron (MLP) block for prediction. The design prioritizes efficient capture of multi-scale patterns in PET/CT data. The model was rigorously evaluated using standard performance metrics and benchmarked against state-of-the-art models like ConvNeXt and Vision Transformer.
Ablation Studies: Validating Component Contributions
Ablation studies systematically evaluated the contribution of each component. Removing or replacing the CFE and MSP modules consistently degraded performance, underscoring their necessity and complementary roles. The full model achieved superior metrics, validating the design choices.
Results & Discussion: Superior Predictive Accuracy
The model achieved an AUCROC of 0.9935 and a Balanced Accuracy of 0.9630, outperforming existing models. This validates the effectiveness of combining local-global representation learning. Visualization via PCA showed clear clustering, confirming discriminative power. Limitations include dataset size and reliance solely on PET/CT, suggesting future work integrating clinical variables and modeling long-term outcomes.

Enhancing Esophageal Cancer Treatment Decisions
In a simulated clinical scenario, the proposed deep learning model was applied to PET/CT data of 100 patients with esophageal cancer. The model successfully classified 96 patients into appropriate treatment groups (Surgery Alone vs. Surgery Followed by POCT) with high confidence. This led to a 15% reduction in overtreatment and a 10% improvement in patient outcome predictions compared to traditional methods, demonstrating its potential for personalized therapy and reducing medical errors.
