The study found that ultrasound B-scan was highly effective in the early detection of regional melanoma metastases compared with physical examination. Earlier detection of such metastases seemed to result in improved overall survival.
FNAC is very reliable for the early detection of melanoma metastases. FNAC is a swift method free of complications and is able to replace diagnostic surgery completely for nonmalignant lesions in a large number of patients. Moreover, FNAC is especially useful in combination with ultrasound in melanoma follow-up and can enable diagnosis of lesions smaller than 1 cm without impairment of sensitivity or specificity.
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.
