Morbidity and Mortality of Melanoma on the Trunk and Extremities Treated With Mohs Surgery Versus Wide Excision: A Systematic Review

Dermatol Surg. 2022 Jan 1;48(1):1-6. doi: 10.1097/DSS.0000000000003250.

Abstract

Background: Recommendations for the approved use of Mohs surgery for cutaneous melanoma on the trunk and extremities remain uncertain.

Objective: To compare survival and recurrence between patients treated with Mohs surgery versus wide excision for melanoma on the trunk and extremities.

Methods: The databases Medline, Embase, Web of Science, CENTRAL, and EMCare were searched from inception on January 11, 2021. Contemporary comparisons were included exclusively. Meta-analysis was conducted using generic inverse variance and a fixed effects model.

Results: Four studies were eligible for inclusion. The study population (n = 279,556) was 52.1% men and 97.2% White. There were no observed differences in 5-year overall survival (hazard ratio 0.98, 95% confidence interval 0.90-1.07, I2 = 0%), disease-free survival (HR 0.89, 95% CI 0.12-6.47, I2 = 0), or local recurrence among patients treated with Mohs surgery relative to wide excision. Quality of the evidence was very low.

Conclusion: This systematic review found survival and local recurrence were comparable among patients treated with Mohs surgery or wide excision for melanoma on the trunk and extremities. Future prospective contemporary studies with more diverse representation that report surgical complications and costs may facilitate more definitive recommendations.
