Implication

Randomized trial assesses radiomic features for lymphadenopathy differentiation in lung cancer and sarcoidosis, suggesting new non-invasive approaches.

Key Points

This study aims to evaluate the efficacy of CT-derived radiomic features in differentiating mediastinal lymphadenopathy caused by lung cancer from that caused by sarcoidosis.
Analyzed 204 histopathologically confirmed mediastinal lymph nodes using a single-center retrospective approach.
Extracted 107 radiomic features from contrast-enhanced thoracic CT images with multiple feature selection and dimensionality reduction techniques.
Implemented patient-level five-fold cross-validation for performance evaluation of different models.
The clinical-only ensemble model achieved an accuracy of 94.92% and ROC–AUC of 0.9733.
Combined clinical–radiomic models showed superior performance, with a correlation-filtered ensemble model achieving the highest accuracy of 97.78% and ROC–AUC of 1.0000.
Radiomics-only LASSO had an ROC–AUC of 0.9108, demonstrating lower performance compared to combined models in certain analyses.
