Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are registered on trial by implementing the registration and eligibility case report forms (CRFs) and forwarding by fax to the Trial Coordinating Centre.
Prior to patient enrolment, the investigator should ensure that all of the following
requirements are met:
· The patient meets all inclusion criteria and none of the exclusion criteria should
apply.
· The patient and investigator have signed and dated all applicable consent forms.
· All baseline assessments and investigations have been performed.
· The eligibility checklist has been completed, signed and dated.

The randomisation will be performed from
the Trial Coordinating Centre with all trial staff blinded to the codes, and with the codes maintained in a locked secure environment. The randomisation process itself will be nonblinded to the trial staff involved.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible patients will be randomised in the ratio of 1:1 between the two arms, initial radiation therapy and initial observation. Allocation to treatment will be balanced by institution and site (head or neck) using the minimisation technique.

Summary
Brief summary
This study is comparing surgery alone with surgery plus post-operative radiation therapy for patients with completely resected primary melanoma showing histological features of neurotropism.

Who is it for?
You may be eligible to join this study if you aged 18 years or above and have been diagnosed with neurotropic primary melanoma in the head/neck area.

Study details
Participants in this study will be randomly allocated (by chance) to one of two groups. Participants in one group will undergo radiation therapy over 4 weeks, commencing within 3 months of surgery. Participants in the other group will undergo surgery followed by observation only.

Participants will be monitored for up to 5 years in order to evaluate treatment effect, survival rates, and quality of life.
