Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a randomised controlled trial of 1 cm versus 2 cm margin of excision of the primary lesion for adult patients with a primary invasive cutaneous melanomas >=1mm thick to determine differences in the rate of local recurrence and melanoma specific survival.

ARM A: Experimental Arm
Wide Local Excision = 1cm Margin
+ Sentinel Lymph Node Biopsy
+/- Reconstruction
These procedures need to be performed +<14 days from the date of randomisation.
Intervention code [1] 289541 0
Treatment: Surgery
Comparator / control treatment
ARM B:Control Arm
Wide Local Excision = 2cm Margin
+ Sentinel Lymph Node Biopsy
+/- Reconstruction
These procedures need to be performed +<14 days from the date of randomisation.

Eligibility
Key inclusion criteria
1 Patients must have a primary invasive cutaneous melanoma of Breslow thickness greater than 1 millimetre as determined by diagnostic biopsy (narrow excision, incision or punch biopsy) and subsequent histopathological analysis.
2 Must have a primary melanoma that is cutaneous (including head, neck, trunk, extremity, scalp, palm, sole).
3 An uninterrupted 2cm margin must be technically feasible around biopsy scar or primary melanoma.
4 Randomisation and the primary study intervention, including staging sentinel node biopsy, must be completed by 120 days of original diagnosis.
5 Patients must be 18 years or older at time of consent.
6 Patient must be able to give informed consent and comply with the treatment protocol and follow-up plan.
7 Life expectancy of at least 10 years from the time of diagnosis, not considering the melanoma in question, as determined by the PI.
8 Patients must have an ECOG performance score between 0 and 1.
9 A survivor of prior cancer is eligible provided that ALL of the following criteria are met and documented:
* The patient has undergone potentially curative therapy for all prior malignancies,
* There has been no evidence of recurrence of any prior malignancies for at least FIVE years (except for successfully treated cervical or non-melanoma skin cancer with no evidence of recurrence), and
* The patient is deemed by their treating physician to be at low risk of recurrence from previous malignancies.
Minimum age
18 Years
Maximum age
120 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1 Uncertain diagnosis of melanoma i.e. so-called ‘melanocytic lesion of unknown malignant potential’.
2 Patient has already undergone wide local excision at the site of the primary index lesion.
3 Patient unable or ineligible to undergo staging sentinel lymph node biopsy of the primary index lesion.
4 Desmoplastic or neurotropic melanoma.
5 Microsatellitosis as per AJCC 2009 definition
6 Subungual melanoma
7 Patient has already undergone a local flap reconstruction of the defect after excision of the primary and determination of an accurate excision margin is impossible.
8 History of previous or concurrent (i.e., second primary) invasive melanoma.
9 Melanoma located distal to the metacarpophalangeal joint, on the tip of the nose, the eyelids or on the ear, mucous membranes or internal viscera.
10 Physical, clinical, radiographic or pathologic evidence of satellite, in-transit, regional, or distant metastatic melanoma.
11 Patient has undergone surgery on a separate occasion to clear the lymph nodes of the probable draining lymphatic field, including sentinel lymph node biopsy, of the index melanoma.
12 Any additional solid tumour or hematologic malignancy during the past 5 years except T1 skin lesions of squamous cell carcinoma, basal cell carcinoma, or uterine/cervical cancer.
13 Melanoma-related operative procedures not corresponding to criteria described in the protocol.
14 Planned adjuvant radiotherapy to the primary melanoma site after Wide Local Excision is not permitted as part of the protocol and any patients given this treatment would be excluded from the study.
15 History of organ transplantation.
16 Oral or parenteral immunosuppressive agents (not topical or inhaled steroids) at any time during study participation or within 6 months prior to enrolment.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation of treatment will be performed centrally via an online randomisation system. Sites will be notified as to which arm treatment the patient was allocated via email.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This is a randomised controlled clinical trial.
This study will use a Permuted block randomisation method for the allocation of subjects into different groups.
Randomisation according to stratification factors: Risk Group, Age, Sex, Site.
Masking / blinding
