Abstract

Despite the revolution in the field of melanoma treatment with the introduction of novel therapies(immunotherapy and target therapy), there is still a percentage of melanoma patients that oftenexperiences drug-resistance and therapeutic failure. The early recognition of therapeutic failure, bythe identification of new biomarkers of therapeutic response, is the main challenge of medical oncologyin order to personalize the therapeutic strategies and avoid the toxicity of ineffective treatments. Thecirculating-free DNA BRAFV600E mutation was proposed as a marker of therapeutic response. However,it cannot be revealed in all melanoma patients with this mutation, detected in tumour biopsy specimens.Therefore, there is a need to identify new prognostic biomarkers. Matrix Metalloproteinase-9 (MMP-9)could be one of them since its role in tumour invasiveness have been demonstrated.
