SNB can be successfully applied to early T1/2 tumors of the oral cavity/oropharynx in a standardized fashion by centers worldwide. For the majority of these tumors the SNB technique can be used alone as a staging tool.
Both clinical staging and routine pathologic staging underestimate the presence of nodal metastases. Staging with either SNB alone or SNB-assisted END shows promise in the management of the N0 neck by identifying patients with micrometastases (pN1mi).
Sentinel node biopsy can be used to upstage the N0 neck in patients with early subclinical nodal disease. However, before it becomes the standard of care in head and neck squamous cell carcinoma, longer follow-up observational trials are needed.
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.
