These results illustrate the feasibility of a wait-and-scan strategy for head and neck PGL. The management strategy could not prevent tumor-induced complications in 16% of nongrowing tumors.
An individual risk is constituted for surgery and radiotherapy, stratified per Fisch class. For class A and B tumours, surgery is a suitable treatment option. For class C and D tumours, radiotherapy results in lower complication rates and similar or better local control rates when compared to the surgical group.
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.
