Predicting pathological subtypes of pure ground-glass nodules using Swin Transformer deep learning model
This study developed a deep learning model based on the Swin Transformer network to predict the pathological subtypes of pure ground-glass nodules (pGGN) on CT scans, distinguishing between AAH/AIS, MIA, and IAC. The model achieved an accuracy of 91.41% and an F1-score of 91.42% on an external validation set, significantly outperforming radiologists. This non-invasive tool can improve diagnostic accuracy, optimize treatment selection, and enhance patient prognosis for pulmonary pGGN.

Performance Comparison: Model vs. Radiologists
| Metric | Deep Learning Model | Radiologists |
|---|---|---|
| Accuracy | 91.41% | 71.88% |
| Precision | 91.94% | 73.43% |
| Recall | 91.41% | 71.88% |
| F1-score | 91.42% | 72.01% |
Impact on Clinical Decision Making
The high accuracy of the Swin Transformer model in distinguishing pGGN subtypes could lead to more precise treatment recommendations. For instance, distinguishing between AAH/AIS (observation) and MIA/IAC (surgical intervention) is critical. This reduces unnecessary surgeries for benign lesions and ensures timely intervention for invasive ones, significantly improving patient outcomes and reducing healthcare costs.
Methodology
The study utilized a Swin Transformer network, a novel deep learning architecture adept at computer vision tasks, trained on a large dataset of CT images. It employed five-fold cross-validation and external validation across multiple institutions to ensure robustness and generalization.

Future Implications
This model represents a significant step towards integrating AI into radiological workflows for early lung cancer diagnosis. Future work will focus on expanding the dataset, including more pGGN types (e.g., focal inflammation), and integrating the model seamlessly into PACS systems for automated image analysis.
Optimizing Patient Prognosis
By providing accurate preoperative diagnosis, this AI model empowers clinicians to make informed decisions regarding patient management. Early and precise classification of pGGN invasiveness ensures that patients receive the most appropriate care, from watchful waiting to targeted surgical intervention, ultimately leading to improved 5-year survival rates and quality of life.
