Details and patient eligibility

About

The hypothesis is that PD-L1[Programmed Death-Ligand 1] labeling in exosomes could be a biomarker of disease progression in melanoma. The rate of circulating exosomes, their size and the exosomal expression of PD-L1 could be correlated with the stage of the disease, the response to treatment and/or the prognosis of patients. In this study, blood samples (EDTA tubes taken as part of routine care at Besançon University Hospital) and associated clinical data are reused.
