Real-World melanoma care under the microscope
NCT ID NCT03605771
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers are studying how advanced and metastatic melanoma is diagnosed and treated in everyday Spanish clinics. The study follows about 400 adults with stage III, metastatic, or unresectable melanoma from their first diagnosis. No experimental treatment is given; instead, the team collects information from medical records to describe who these patients are and what care they receive.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the study maps real-world melanoma care well, it could help doctors and health systems spot gaps in diagnosis and treatment for advanced disease.
- What could go wrong
- This study only observes what already happens in clinics, so it cannot prove that any treatment works. Its findings may reflect local Spanish practice and may not apply elsewhere.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients of legal age with stage III, metastatic, or unresectable melanoma at first diagnosis after January 8, 2018. First diagnosis is understood as: a. Disease onset as metastatic or unresectable disease; b. First metastatic or unresectable relapse in the pre-established dates (after January 8, 2018) in a patient with previous localised melanoma and completely resected on dates before the pre-inclusion period. * Signing the Informed Consent Form (ICF). * A patient may have received the first or subsequent treatments for metastatic or unresectable disease in a hospital other than the centre where the ICF was signed, as long as the patient meets the inclusion criteria 1. * A patient can only sign one ICF (cannot sign an ICF in two different centres). * If a patient signs the ICF in a centre during the first-line therapy and then goes to another centre with consideration for the following lines: If the centre is associated with the GEM-1801 study, researchers will do their best to update the following lines and the patient status, introducing the new information in the centre where the ICF was initially signed. This information will be provided by the patient before contacting the principal investigator and always with prior consent of the patient, who will have previously provided the consent to contact by telephone for this purpose. If this second (or subsequent) centre is not associated with the GEM- 1801 study, this will be considered loss of follow-up, unless the patient returns to the GEM-1801 start centre, wherein the reporting physicians will do their best to update the information from other centres, always with prior patient consent, who will have previously signed the ICF; c) A patient card with the assigned code will be delivered. Exclusion Criteria: * Any patient not complying with inclusion criteria.
