Radiation zaps may buy time for melanoma patients
NCT ID NCT07112170
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is for people with metastatic melanoma whose cancer has started growing in a few spots despite treatment. Researchers want to see if giving high-dose, precise radiation to those spots can delay further spread. About 52 adults will take part, and the main goal is to see how long they can go without the cancer getting worse.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 or older * ECOG 0-2 * Willing and able to provide informed consent * Metastatic melanoma detected on imaging and clinically confirmed. * Treated with first line immunotherapy or BRAF inhibitors. * No upper limit to the number of total metastatic sites, but a maximum of ten progressive metastatic sites, inclusive of primary disease and metastatic lesions, all of which must be extra cranial. * Patients who had any prior radiation therapy near or overlapping with the oligoprogressive sites are allowed to enroll. * All sites of oligoprogression that can be safely treated with SBRT or hypofractionated radiotherapy. Exclusion Criteria: * \>10 extracranial sites of progressive disease. * Pregnancy. * Leptomeningeal disease. * Serious medical comorbidities precluding radiotherapy, such as ataxia-telangiectasia or scleroderma. * Prior radiotherapy near the oligoprogressive lesion precluding SBRT or hypofractionated radiotherapy due to exceeding OAR tolerance. * Any psychological, sociological or geographical issue potentially hampering compliance with the study. * Any other condition which in the judgment of the investigator would make the patient inappropriate for entry into this study.
