Lymph Nodes of Patients with Regional Metastases from Head and Neck Squamous Cell Carcinoma as a Predictor of Pathologic Outcome: Size Changes at CT before and after Radiation Therapy

Our purpose was to clarify the importance of size changes of regional metastases from head and neck squamous cell carcinoma on CT scans obtained before and after radiation therapy (RT) as a predictor of pathologic outcome.
