BACKGROUND: Sentinel lymph node biopsy (SLNB) has emerged as a widely used staging procedure for cutaneous melanoma. However, debate remains around the accuracy and prognostic implications of SLNB for cutaneous melanoma arising in the head and neck, as previous reports have demonstrated inferior results to those in nonhead and neck regions. Through the largest single-institution series of head and neck melanoma patients, the authors set out to demonstrate that SLNB accuracy and prognostic value in the head and neck region are comparable to other sites. METHODS: A prospectively collected database was queried for cutaneous head and neck melanoma patients who underwent SLNB at the University of Michigan between 1997 and 2007. Primary endpoints included SLNB result, time to recurrence, site of recurrence, and date and cause of death. Multivariate models were constructed for analyses. RESULTS: Three hundred fifty-three patients were identified. A sentinel lymph node was identified in 352 of 353 patients (99.7%). Sixty-nine of the 353 (19.6%) patients had a positive SLNB. Seventeen of 68 patients (25%) undergoing completion lymphadenectomy after a positive SLNB result had at least 1 additional positive nonsentinel lymph node. Patients with local control and a negative SLNB failed regionally in 4.2% of cases. Multivariate analysis revealed positive SLNB status to be the most prognostic clinicopathologic predictor of poor outcome; hazard ratio was 4.23 for SLNB status and recurrence-free survival (P < .0001) and 3.33 for overall survival (P < .0001). CONCLUSIONS: SLNB is accurate and its results are of prognostic importance for head and neck melanoma patients. Cancer 2012;118:1040-
Objective
Presentation of a case of pediatric laryngeal neurofibroma (LNF) and review of the world literature.
Data Sources/Review methods
Comprehensive review of the world literature using Pubmed and Google Scholar.
Results
Pediatric LNF was identified in 62 cases reported in the world literature. The most common presenting symptom is stridor and the most common location of the tumor in the larynx is the aryepiglottic fold. Recent reports demonstrate increased utilization of endoscopic resection with reduced need for tracheostomy.
Conclusion
Pediatric LNF is a rare disorder. Review of the world literature since 1940 suggests a recent trend away from aggressive open resection and towards more conservative endoscopic resection with excellent functional results.
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.
