Background: Evaluation of newly diagnosed patients with melanoma for metastasis is requisite to treatment planning. The reported diagnostic yield of whole-body conventional radiological imaging in initial staging of patients with melanoma is low. However, the diagnostic yield of positron emission tomography (PET) for distant metastases is unclear. Hypothesis: There is no utility of PET as part of a routine metastatic survey in patients with T2 to T4 melanoma.
IIC is a viable alternative to frozen sectioning when intraoperative evaluation is desired. IIC is significantly more sensitive for macrometastases. IIC evaluation of SLNs in melanoma makes a single operative procedure possible for a significant proportion of patients with regional nodal metastases.
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.
