Molecular Characterization of Advanced Stage Melanoma by Blood Sampling

Analysis of somatic mutations in tumors is currently indicated for daily practice in all metastatic melanoma. Actually, this research is limited to the mutation of three biomarkers validated by the l'Institut National du CAncer (INCA): BRAF, NRAS and CKIT. Moreover, in some cases it requires invasive biopsies. In this context, molecular characterization of a tumor material flowing (circulating tumor DNA and / or circulating tumor cells) could afford to benefit patients in the best conditions of current targeted therapies and future.
