Core Concepts
NCCN's 2024 guidelines for cutaneous melanoma reflect incremental advances and expert consensus, emphasizing the importance of frequent updates and evolving evidence.
Abstract
The National Comprehensive Cancer Network (NCCN) has released new guidelines for cutaneous melanoma, diverging from the American Academy of Dermatology (AAD) recommendations. Dr. Susan Swetter, a key figure in developing both sets of guidelines, highlights the importance of evolving science in shaping best practices. The 2024 NCCN guidelines emphasize incremental advances, such as changes in biopsy procedures and surgical margins, to improve diagnostic accuracy and outcomes. These guidelines, based on expert consensus, aim to provide updated and evidence-based recommendations for managing cutaneous melanoma.
Key Highlights:
NCCN guidelines reflect incremental advances and evolving evidence.
Differences between NCCN and AAD recommendations stem from evolving science.
Emphasis on frequent updates and expert consensus in guideline development.
Changes in biopsy procedures and surgical margins to improve outcomes.
Importance of evidence-based recommendations for managing cutaneous melanoma.
Stats
The last iteration of NCCN guidelines was published only 1 year ago.
A 2A recommendation is based on nondefinitive evidence but represents near uniform expert consensus.
Margins of 2 cm appear to be sufficient for advanced T3 and T4 tumors.
Guidelines call for surgical margins of at least 1 cm and no more than 2 cm for large invasive melanomas.

"Guidelines not only identify what further steps can be taken to improve diagnostic accuracy or outcomes but what practices can be abandoned to improve the benefit-to-risk ratio." - Dr. Susan Swetter
"A double negative result is not 100% effective, but it is high." - Dr. Caroline C. Kim
