Abstract

BACKGROUND/AIM: Margin size during wide excisional surgery for invasive melanoma treatment have been established by national guidelines. This study identified factors associated with wider than recommended excisional margins and its impact on survival. PATIENTS AND METHODS: The National Cancer Database was queried to identify patients with primary invasive melanoma. Statistical analysis was performed using univariate and multivariate analysis. Overall survival was compared using Kaplan-Meier method. RESULTS: A total of 26,440 patients were included in the analysis. Melanomas located on the trunk were more likely to be treated using wider than recommended excisional margins for certain Breslow depth groups (p<0.05), while the opposite was true for those being treated in an academic/research program (p<0.05). The practice of taking wider than recommended margins was not associated with improved survival. CONCLUSION: Tumor location and facility type influence non-compliance with the National Comprehensive Cancer Network guidelines. Lack of survival benefit in patients with wider excisional margins seems to support guideline recommendations.
