Summary

Patients with a primary invasive melanoma are recommended to undergo excision of the primary lesion with a wide margin. There is evidence that less radical margins of excision may be just as safe. This is a randomised controlled trial of 1 cm versus 2 cm margin of excision of the primary lesion for adult patients with stage II primary invasive cutaneous melanomas (AJCC 8th edition) to determine differences in disease-free survival. A reduction in margins is expected to improve patient quality of life.

Detailed description

This study will determine whether there is a difference in disease-free survival rates for patients with primary cutaneous melanoma with Breslow thickness \> 2mm or 1-2mm with ulceration (pT2b-pT4b, AJCC 8th edition), treated with either a 1cm excision margin or 2cm margin. The study is designed to be able to prove or disprove that there is no difference in risk of the tumour recurring around the scar or anywhere else in the body between the two groups of patients. If the study shows no risk of tumour recurrence then we will also be able to determine how much of an impact the narrower excision has on patients in terms of improved quality of life and reduced side effects from the surgery and melanoma disease. This trial will also evaluate and determine the economic impact of narrower excision margins on the health services and society in general.

Conditions

• Cutaneous Melanoma, Stage II

Interventions

Type	Name	Description
PROCEDURE	Wide Local Excision = 1cm Margin	A wide local excision involves removing an extra "safety margin" of skin surrounding the original melanoma site, to ensure that any remaining scattered melanoma tumour cells that may have been left behind after the first initial biopsy/surgery are removed.
PROCEDURE	Wide Local Excision = 2cm Margin	A wide local excision involves removing an extra "safety margin" of skin surrounding the original melanoma site, to ensure that any remaining scattered melanoma tumour cells that may have been left behind after the first initial biopsy/surgery are removed.
