Elective neck dissection versus positron emission tomography-computed tomography-guided management of the neck in clinically node-negative early oral cavity cancer: A cost-utility analysis.

END is a cost-effective strategy compared with PET-CT in patients who have node-negative oral cancer. Although lower PET standardized uptake value thresholds would result in fewer false negatives and improved NPV, it is still uncertain that PET-CT would be cost effective, as this would likely result in more false positive tests.
