Deep Learning-Based Automated Masseter Muscle Area on Routine CT Stratifies Survival in Oral Cancer
Challenge: Oral cancer survival rates remain challenging despite treatment advancements, underscoring the need for objective, scalable prognostic markers. Sarcopenia, a critical determinant of clinical outcomes, is difficult to assess routinely due to labor-intensive manual segmentation.
AI Solution: This study developed and validated a U-Net-based deep learning model for automated masseter muscle segmentation on routine head and neck CT scans. This AI-driven tool quantifies masseter muscle area (AI-MMA) rapidly and objectively, addressing limitations of manual methods.
Impact: The AI-MMA significantly correlated with overall survival in oral cancer patients, demonstrating its potential as an independent prognostic biomarker. Automated assessment facilitates earlier risk stratification and personalized treatment planning.

HR 2.584
Low AI-MMA is an independent predictor of mortality, demonstrating critical prognostic value.
The AI-derived masseter muscle area (AI-MMA) was independently associated with poorer overall survival (HR, 2.584; 95% CI, 1.132–5.898; p=0.024), alongside advanced tumor stage and low BMI. This underscores AI-MMA's clinical relevance as a prognostic biomarker beyond conventional staging, providing an objective measure of patient vulnerability.

Prognostic Stratification
Our U-Net based model achieved a Dice Similarity Coefficient (DSC) of 0.92, indicating high spatial overlap with manual segmentations. The model was trained on 348 patients and validated on an independent cohort of 247 patients, ensuring robustness and generalizability. This rigorous development process is key for reliable enterprise deployment.
| Feature | Manual Segmentation | AI-Automated Segmentation |
|---|---|---|
| Speed | 5-10 minutes per CT slice |
|
| Objectivity | Subject to inter/intra-observer variability |
|
| Scalability | Labor-intensive, limits widespread adoption |
|
| Integration | Requires specialized clinician time |
|
The AI model processes CT slices in less than 1 second, a significant reduction from the 5-10 minutes required for manual segmentation. This dramatically improves clinical workflow efficiency, allowing for rapid sarcopenia assessment and enabling clinicians to identify high-risk patients promptly. Such speed and accuracy are crucial for high-volume oncology centers.
