[Clinical study of cervical lymph node metastasis in oral tongue squamous carcinoma by a machine learning model based on contrast-enhanced CT radiomics].

Purpose: To investigate the value of machine learning model based on enhanced CT imaging features and clinical parameters in predicting cervical lymph node metastasis in patients with tongue squamous cell carcinoma (TSCC).

Methods: A total of 75 patients with TSCC who were treated in the Affiliated Stomatology Hospital of Nanjing Medical University from January 2015 to July 2022 were collected. All patients had complete clinical data, enhanced CT image data and postoperative cervical lymph node pathological examination results.
