Predicting lymph node spread in early esophageal squamous cell carcinoma

Deep Learning and Radiomics for Prediction of Lymph Node Metastasis in Early-stage Esophageal Squamous Cell Carcinoma

Observational The First Affiliated Hospital of Anhui Medical University · NCT07050576

This project will use deep learning on preoperative CT scans to try to predict whether people with early-stage esophageal squamous cell carcinoma have lymph node metastasis.

What this trial studies

This observational effort uses contrast-enhanced CT images taken within two weeks before surgery from patients with pathologically confirmed T1 esophageal squamous cell carcinoma who have not received prior treatment. Radiomics features will be extracted from imaging and combined with deep-learning methods to build a predictive model of lymph node metastasis. The model development is based on surgical pathology as the reference standard and excludes cases with poor image quality or incomplete pathology. The goal is a non-invasive tool to help guide clinical treatment decisions about the need for more extensive surgery or additional therapies.

Who should consider this trial

Good fit: Ideal candidates are patients with pathologically confirmed T1 ESCC who have preoperative contrast-enhanced CT performed within two weeks before surgical resection and who have not received neoadjuvant or endoscopic therapy.

Not a fit: Patients with more advanced disease (beyond T1), prior neoadjuvant or endoscopic treatment, poor or missing CT imaging, incomplete pathology, or distant metastases are unlikely to benefit from this model.

Why it matters

Potential benefit: If successful, the model could help clinicians identify lymph node metastasis non-invasively and guide more personalized surgical or treatment planning.

How similar studies have performed: Previous radiomics and AI studies for predicting lymph node metastasis in esophageal cancer have shown promising but variable accuracy, so this work builds on emerging but not yet definitive evidence.
