Imaging EBV-Positive Nasopharyngeal Cancer: 68Ga-DOTATATE vs. 18F-FDG PET/CT

Nasopharyngeal carcinoma, a type of cancer prevalent in certain regions, has a strong link to the Epstein-Barr virus (EBV). This study wanted to find out which imaging method, 68Ga-DOTATATE PET/CT or 18F-FDG PET/CT, was better for detecting and managing EBV-positive nonkeratinizing nasopharyngeal carcinoma. 68Ga-DOTATATE binds to somatostatin receptors, which are often overexpressed in cancer cells. In contrast, 18F-FDG highlights areas of high glucose metabolism, a common trait in rapidly growing tumors. Both methods have their strengths, but the question remains: which one gives doctors the clearest picture of EBV-positive nonkeratinizing nasopharyngeal carcinoma? Patients with this cancer type were scanned using both techniques. The results showed that 68Ga-DOTATATE PET/CT was more accurate in detecting primary tumors and metastases. However, 18F-FDG PET/CT sometimes spotted lesions that 68Ga-DOTATATE missed. Doctors and researchers need to consider both imaging methods' advantages when treating and studying EBV-positive nonkeratinizing nasopharyngeal carcinoma. Combining the strengths of each could lead to better patient outcomes.
