Abstract

The uptake of L-1-[C-11]-tyrosine (TYR) in cervical lymph nodes of eleven patients with squamous-cell carcinoma (SCC) of the oral cavity was studied with PET to detect lymphogenic metastases. Methods: The TYR-PET results were compared with clinical, MRI, CT, histopathologic findings and historical data of patients studied with FDG. Sensitivity, specificity, accuracy and the positive and negative predictive values were calculated. Results: TYR-PET had sensitivity of 83% and a specificity of 95%, In contrast, the sensitivity and specificity for MRI were 33% and 96%, respectively. The sensitivity and specificity for CT were 55% and 91%, respectively, TYR-PET results compared favorably with FDG. Conclusion: With NR-PET, SCC metastases of the oral cavity can be visualized with high sensitivity and specificity, TYR-PET can be an additional tool for further evaluation of neck malignancies.
