2-cm versus 4-cm surgical excision margins for primary cutaneous melanoma thicker than 2 mm: long-term follow-up of a multicentre, randomised trial. Lancet 2019; 394: 471-477.

Published: 12th November 2019

Authors: Utjes D, Malmstedt J, Teras J, Drzewiecki K, Gullestad HP, Ingvar C et al.

Conclusion

After a median of 19.6 years, follow-up of the 936 patients included showed no difference in overall survival (unadjusted hazard ratio for 2cm margin 0.98, 95per cent confidence interval 0.83 to 1.14, P=0.75), or in deaths attributed to melanoma (0.95, 0.78 to 1.16, P=0.61).
