PSC patients present with more advanced stage and with worse survival outcomes than other NSCLC patients. While surgical resection conveys a survival advantage in PSC, this group represents a population at a high risk for relapse and should be evaluated for novel adjuvant therapies.
A substantial number of well-staged carcinoid patients had LN metastases. Large tumor size is a valuable predictor of carcinoid nodal disease. LN involvement was an independent predictor of worse survival. Nodal dissection in tumors > 2 cm and in atypical subtype can yield important prognostic information.
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.
