Eligibility
Key inclusion criteria
- Aged 18 years or older

- Has provided written informed consent for participation in this trial

- Histologically confirmed neurotropic primary melanoma

- Neurotropism is identified pathologically by the presence of melanoma cells
around nerve sheaths (perineural invasion) or within nerves (intraneural
invasion).

- Occasionally, the tumour itself may form neuroid structures (termed 'neural
transformation'; this is also regarded as neurotropism)

- "normal"-looking nerves that appear to be "entrapped" within the tumour should
not be regarded as neurotropism

- Tumour located above the clavicle and below the jaw or occiput (neck primary) or above
the jaw/occiput (head primary)

- Complete macroscopic resection of all known disease

- No previous surgery for melanoma (other than complete macroscopic resection as stated
above)(i.e. Not recurrent disease)

- No evidence of in-transit, nodal or distant metastases as determined by clinical
examination, CT or MRI

- ECOG performance status score of 2 or less

- Life expectancy greater than 6 months

- Patients capable of childbearing are using adequate contraception

- Available for follow up
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Women who are pregnant or lactating

- Intercurrent illness that will interfere with the radiation therapy such as
immunosuppression due to medication or medical condition

- Clinical and/or MRI evidence of a named cranial or cervical nerve involvement by
tumour

- Inability to localise surgical bed on CT scans and/or surgical margins (cm) not known

- Previous radical radiation therapy to the head and neck, excluding superficial
radiation therapy to cutaneous SCC or basal cell carcinoma, which is not within or
overlapping the tumour bed

- High risk for poor compliance with therapy or follow-up as assessed by investigator

- Patients with prior cancers, except: those diagnosed = 5 years ago with no evidence of
disease relapse and clinical expectation of relapse of less than 5%; prior
successfully treated Level 1 cutaneous melanomas = 2 years ago; or non-melanoma skin
cancer; or carcinoma in situ of the cervix

- Albinism

- Participation in other clinical trials with the same primary endpoint

Summary
Brief summary
This is a 2-armed randomised controlled trial comparing surgery alone with surgery plus
post-operative radiation therapy for patients with completely resected primary melanoma
showing histological features of neurotropism. Uncontrolled studies suggest that this form of
primary melanoma has a high risk of local recurrence and that postoperative radiation therapy
may substantially reduce that risk. Patients who are eligible on the basis of the pathology
of the excised melanoma will be offered the opportunity to take part in the trial. Those
randomised to receive radiation therapy will be treated with a simple technique encompassing
the surgical bed plus a margin. Radiation will commence within 3 months of surgery (maximum
of 14 weeks from surgery to start of radiotherapy).
