The Impact of Surgical Margin in Wide Local Excision of Pediatric Melanoma – An Argument for a More Conservative Approach
Topic overview
Study of 59 pediatric melanoma patients demonstrates that narrow surgical margins (<2 cm) in wide local excision achieve excellent outcomes with no local recurrence at 52-month median follow-up. Head and neck melanomas were less likely to meet NCCN margin guidelines but showed comparable safety, supporting more conservative surgical approaches in pediatric patients where tissue preservation is critical.
Key takeaways
- 61% of pediatric melanoma WLE cases used margins <2cm, with no local recurrence observed at median 52-month follow-up.
- Head/neck melanomas were significantly less likely to achieve NCCN-recommended margins compared to trunk/extremity lesions.
- Narrow surgical margins (<2cm) showed no difference in complication rates or need for intervention versus wider margins (≥2cm).
- Conservative margin approach may be appropriate for pediatric melanoma given anatomic constraints and excellent outcomes with <2cm margins.
- NCCN guideline adherence was challenging in pediatric patients, particularly for head/neck primaries, without compromising oncologic safety.
