Abstract

Background: There is a paucity of literature on treatment of melanoma in children with surgical management extrapolated from adult experience. The incidence and clinical outcomes of pediatric extremity melanoma were studied. Methods: SEER registry was analyzed between 1973 and 2010 for patients < 20 years old with extremity melanoma. Multivariate and propensity-score matched analyses were performed to identify independent predictors of survival. Results: Overall, 917 patients were identified with an age-adjusted incidence of 0.2/100,000 persons, annual percent change 0.96. Most had localized disease (77%), histology revealing melanoma-not otherwise specified (52%). Surgical procedures performed included wide local excision (50%), excisional biopsy (32%), lymphadenectomy (LA) (28%), and sentinel lymph node biopsy (SLNB) (15%). Overall, 30-year disease specific mortality was 7% with lower survival for extremity melanoma (90%), males (89%), nodular histology (69%), and upper distant disease (36%) (all P < 0.05). Posttreatment multivariate analysis revealed localized disease (OR 0.02; P = 0.006) as an independent prognosticator of survival; earlier diagnostic years 1988–1999 (OR 306.4; P = 0.001) were a negative prognosticator of survival. Propensity-score matched analysis found no difference in survival between SLNB/LA vs no sampling for regional/distant disease. Conclusions: Pediatric extremity melanoma in SEER demonstrate no survival advantage between children undergoing sampling procedures vs no sampling for regional/distant disease. Type of study: Retrospective, prognostic study. Level of evidence: III.
