MSG/BAPS

Randomised trial of width of excision of thick cutaneous malignant melanoma.

Disease site: Melanoma

Treatment modality: Surgery

Status: Closed

Trial details

The UK Melanoma Study Group and the British Association of Plastic Surgeons (MSG/BAPS) multi-centre randomised trial of surgical width of excision margin in patients with thick cutaneous malignant melanoma recruited 900 patients between 1993 and 2001 to determine the optimal margin of excision.

Eligible patients with a single primary histological diagnosis of malignant melanoma 2mm Breslow thickness were randomised to a 1cm or 3cm surgical excision margin. In addition to the UK, patients were recruited from Poland and South Africa and the trial was run in collaboration with the Scottish Cancer Therapy Network.

After a median follow-up of 60 months, MSG-BAPS concluded that a 1cm margin for excision of melanoma is associated with a significantly greater risk of loco-regional recurrence, but that there was little difference in overall survival between the two groups. Pending analysis after longer term follow up, the authors of the publication recommended that patients be given the choice after informed discussions of the surgical options, but that it may be prudent to use a 3cm margin excision in patients with deeper tumours.
