About this trial
The primary objective is to evaluate the possibility of using minimally and non-invasive technologies (skin patch and breath analyzer) based on the detection of volatile organic compounds (VOCs) for the early identification of metastases. The secondary objective is to evaluate the usability of these technologies in the follow up of high-risk melanoma patients.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Be over 18 years old
Have a histopathological confirmed melanoma diagnosis (stage II, III or IV AJCC)
Disqualifiers
Not signing the informed consent form
Present other cancers or chronic diseases (such as diabetes, asthma, etc.), which may affect the volatile organic compound profiles
Trial population
Adult population (over 18 years of age) diagnosed with melanoma that are currently being treated at the Hospital Clinic de Barcelona or that are admitted before or at the time of the enrolment in the study.
Trial design
Case-control
Prospective
Treatments tested in this trial
Breath analyzer
DeviceThe study subject will be advised to sit quietly for minimum 10 minutes prior the sampling to avoid temporal changes in levels of volatile organic compunds (VOCs) related to body movement or try to avoid abrupt changes in body posture. Then, he/she will be asked to blow in the breath analyzer in order to obtain the exhaled VOCs profile.
Skin patch
DeviceA skin patch will be placed in the anterior part of the patient's arm for the obtention of the skin VOCs profile (estimated sampling time of around 1 h). These profiles will be recorded with a dedicated software and analyzed using standard statistical methods.
Liquid biopsy
GeneticCirculating free tumor DNA (cfDNA) will be extracted from patient's blood and analyzed to detect mutations in BRAF and other prognostic genes.

Primary outcomes
Early identification of metastases
The primary objective of the study is to evaluate the possibility of using minimally and non-invasive technologies (skin patch and breath analyzer) based on the detection of volatile organic compounds (VOCs) for the early identification of metastases.
Secondary outcomes
Follow-up of high-risk melanoma patients
The secondary objective is to evaluate the possibility to follow-up high risk melanoma patients using minimally invasive technologies based on the detection of changes in the patterns of volatile organic compounds (VOCs).
