Combined features

This study utilized data on the status of station 4 lymph nodes in non-small cell lung cancer (NSCLC) spanning January 2017 to January 2024. Radiomics features were extracted from regions of interest (ROIs) in station 4 lymph nodes across pN0-pN2 stages, derived from venous-phase CT imaging, and integrated with clinically relevant features collected from hospital records to develop a multimodal predictive model. The combined model aims to improve the accuracy of predicting metastasis in NSCLC station 4 lymph nodes.
