Abstract
Background
For melanoma patients, surgery is a standard treatment for locoregional skin metastasis (LSM).
Objectives
To assess the frequency, and risk factors for positive margins after excision of LSM and their impact on patient overall survival (OS) and progression-free survival (PFS).
Materials & methods
A monocentric, retrospective observational study was performed including 87 patients with LSM who had undergone surgical excision.
Results
Positive margins were found in 45% of patients after excision. After additional excision, 28% of patients still had positive margins. Interestingly, there was no difference in PFS or OS for clear margins after the first or additional excision or for margins that remained positive without additional excision. LSM size was the only identified predictive factor for positive margins.
Conclusion
This is the first reported study investigating the frequency of, and risk factors for positive margins of cutaneous LSM, which raises the question of whether additional excision should be performed following positive margin excision.
