Shoulder-arm morbidity following axillary dissection is a frustrating polysymptomatic disease that seems to be relatively unaffected by therapeutic measures. The surgical trauma necessary for adequate tumor staging (removal of 10 lymph nodes) seems decisive for the postsurgery syndrome following axillary dissection. For node-positive patients complete axillary clearing may improve tumor control without worsening long-termmorbidity. New techniques, such as the sentinel-node-biopsy, that selects patients with negative axillary status while preserving the integrity of axillary structures, may improve the overall morbidity.
Despite excellent visualization of anatomical landmarks and improved long-term morbidity, endoscopic lymph node dissection cannot be regarded as a suitable technique for routine axillary management in breast cancer because of long operating times.
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.
