In patients with cN0 SCC of the oral cavity, FDG-PET does not contribute to the preoperative workup. FDG-PET does not replace SOHND as a staging procedure.
Image reconstruction adapted to low photon attenuation in the head and neck area may improve image quality and the diagnostic value of FDG-PET, despite a slightly higher false positive rate attributable to the fact that visualisation of FDG accumulation in benign reactive lymph nodes is also enhanced.
Ultrasound-guided fine-needle aspiration cytology currently is 1 of the most reliable staging techniques in cN0 SCCOC. Regular follow-up could perhaps be limited from 5 to 2 years of prescheduled follow-up visits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
