Correlation of Molecular Response as Measured by 18-FDG Positron Emission Tomography With Outcome After Chemoradiotherapy in Patients with Esophageal Carcinoma

A correlation was found between the depth of tumor invasion and the baseline SUV. The post-treatment SUV predicted for disease-free survival in the definitive chemoradiotherapy group. Caution should be exercised in using post-treatment PET scans to determine the necessity for surgical resection.
