The final pathologic diagnoses were esophageal squamous cell carcinoma in 10 and high-grade dysplasia in 5. ResultsĪ total of 147 subjects were included in the analysis suspicious esophageal lesions were identified by PET/CT scan in 8 (5.44%) and by narrow-band imaging in 35 (23.81%).
Descriptive statistics, receiver operating characteristic curve analysis, logistic regression analysis, independent Student’s t-test, and Kaplan–Meier survival analysis were conducted with MedCalc Statistical Software. Methodsįrom November 2015 to November 2018, all head and neck cancer patients who underwent both PET/CT scan and narrow-band imaging endoscopy at Changhua Christian Hospital were retrospectively enrolled.
We aimed to compare PET/CT scan and narrow-band imaging endoscopy for the detection of esophageal cancer in head and neck cancer patients. Narrow-band imaging endoscopy is an accurate and convenient technique for esophageal examination. Although Positron emission tomography (PET)/computed tomography (CT) scan is commonly conducted in head and neck patients, its ability to detect early esophageal cancer is limited. Second primary cancer of the esophagus is frequent in head and neck patients, especially in high-risk populations, and has a great impact on the prognosis.
