1cm Wide Local Excision margin + Sentinel Lymph Node Biopsy +/- Reconstruction

2 cm Wide Local Excision margin + Sentinel Lymph Node Biopsy +/- Reconstruction

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.

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.

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.

Time from randomisation to clinically, histologically or radiologically confirmed recurrence of melanoma

Time from randomisation to any clinically, histologically or radiologically confirmed local recurrence of melanoma including satellite lesions and in transit metastases to regional draining lymph nodes

Time from randomisation to death from any cause

Measured by FACT-M (Functional Assessment of Cancer Therapy - Melanoma) questionnaire - It consists of two subsections: The FACT-G subsection is a 27-item compilation of general questions divided into four primary QOL domains: Physical Well-Being, Social/Family Well-Being, Emotional Well-Being, and Functional Well-Being. It is considered appropriate for use with patients with any form of cancer. The Melanoma Surgery Subscale evaluates melanoma-specific symptoms such as surgical morbidity and side effects.

Measured by EuroQoL EQ-5D-5L questionnaire - This tool contains 5 domains including mobility, self-care, usual activities, pain/discomfort and anxiety/depression.

The following surgical adverse events will be recorded from the time of surgery to 90 days following surgery (inclusive):

* wound dehiscence
* seroma/haematoma
* haemorrhage
* infection
* skin graft failure
* necrosis of flap used for reconstruction
* deep venous thrombosis
* urinary tract infection
* pneumonia
* cardiac complications
* lymphoedema

An Adverse Event (AE) is any untoward medical occurrence in a participant administered a treatment which does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavourable or unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the treatment timing, whether or not considered related to the treatment. An AE is any adverse change (developing or worsening) from the participant's pre-treatment condition, including intercurrent illness.

Data collected for economic analysis will be from hospital notes, MBS and PBS data (Australia) and patient reported outcome measures (including an employment questionnaire) at baseline, 3, 6, 12 and 24 months and at melanoma recurrence.
