This retrospective study was, to our knowledge, the largest ever reported in the literature. This series confirmed the risk factor of this lesion as well as the lesion's influence on the survival rate. Surgery is the most important part of the treatment. Local recurrences were responsible for the poor prognosis of this lesion.
The strategy to avoid a neck dissection is safe in patients with a complete response in the neck, regardless of initial nodal stage. In patients with residual neck disease, postRCT neck dissection can be performed with limited morbidity. Progress is warranted to optimize the pathological response in the nodes and to better assess ambiguous nodal responses with multi-modal imaging.
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.
