Sentinel lymph node biopsy for melanoma and other melanocytic tumors in adolescents.

Abstract：

BACKGROUND/PURPOSE:Melanoma is rare, accounting for only 1% of all pediatric malignancies. The management of pediatric melanoma is controversial but largely parallels that of an adult occurrence. Sentinel lymph node biopsy (SLNBX) has become a standard of care for adults with melanoma, but the role of this procedure in the staging of pediatric patients remains to be established. The goal of this study was to determine outcomes and complications of children and adolescent patients undergoing SLNBX at the authors' institution. METHODS:A retrospective review of patients younger than 21 years (N = 20) undergoing SLNBX for melanoma or other melanocytic skin lesions at the University of Colorado Health Science Center between 1996 and 2003 was conducted. RESULTS:Sentinel lymph node biopsy was successful in all 20 patients, and 8 patients (40%) were found to have metastases within the sentinel node. As in adults, the sentinel node status correlates with primary tumor depth. No complications occurred in patients undergoing SLNBX, but 4 clinically significant complications (57%) occurred in the 7 patients undergoing a completion lymph node dissection. At 33 months median follow-up, all patients were disease free. CONCLUSIONS:Sentinel lymph node biopsy can be successfully and safely performed in pediatric patients for melanoma and atypical nevi. However, the prognostic information and therapeutic implications of SLNBX results for children and adolescents remain unclear. Completion lymph node dissection for microscopic disease is a morbid procedure with uncertain benefit to pediatric or adult patients with a positive SLNBX result. Long-term follow-up data are needed before SLNBX can become a standard of care in pediatric melanoma or as a diagnostic tool to distinguish the atypical Spitz nevus from melanoma.
