Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals with a histologically confirmed diagnosis of melanoma who can provide informed consent.

Probably not a fit

Patients with significant systemic diseases or those unable to provide informed consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the Cytophone, a patented system designed to identify and count circulating melanoma cells in the bloodstream. By analyzing a significantly larger volume of blood than traditional tests, the Cytophone aims to detect these rare cells non-invasively, without the need for injections or incisions. The study seeks to establish a correlation between circulating tumor cell counts and the risk of melanoma metastasis, recurrence, and treatment efficacy, potentially allowing for earlier intervention in patients. The trial will involve patients with a confirmed diagnosis of melanoma who can provide informed consent and sit for the procedure.

Why it matters

Potential benefit: If successful, this method could enable earlier detection of melanoma metastasis, improving patient outcomes through timely intervention.

How similar studies have gone: While the approach of using circulating tumor cells for early detection is gaining traction, the specific use of the Cytophone device represents a novel application in this context.

Exclusion Criteria:

* Unable to provide informed consent to participate in the study, such as a mental condition rendering the participant unable to understand the nature, scope, and possible consequences of the study;
* Clinically relevant cardiovascular, hepatic, neurological (e.g., evidence of organic brain syndrome), endocrine, or other major systemic disease making implementation of the protocol or interpretation of the study results difficult or that would put the participant at risk by participating in the study;
* Persistent significant or severe infection, either acute or chronic;
