Brief Summary:
The main objective of this project is to perform a longitudinal monitoring of BRAF and NRAS cell-free DNA in a large cohort of metastatic melanomas patients before treatment and during the follow-up. Results will be compared with clinical data as imaging (based on RECIST criteria) and the activity of lactate dehydrogenase in serum (LDH).

Condition or disease Intervention/treatment Phase
Malignant Melanoma Stage IV Malignant Melanoma Stage III Biological: quantification of BRAF and NRAS mutation Not Applicable

Detailed Description:

During a consultation of follow-up for an advanced malignant melanoma (stage IIIb or IIIC or IV), an investigator presents the study to the patient and give him the note of information and the informed consent.

The patient can benefit from a reflexion period of of 7 days.

In case of agreement, a first blood draw will take place before initiation of any treatment. Between D15 and D30 a second blood draw will be taken. Then a blood draw will be necessary every two months until recurrence or progression of the disease for a maximum of 22 months.

Arm Intervention/treatment
Experimental: Patient with malignant melanoma
Patient with advanced or metastatic malignant melanoma (stage IIIB inoperable or IIIC or stage IV) will have a first blood test before any treatment, then at day 15 or 30 after initiation of therapy, and every two months until recurrence or progression for a maximum of 22 months.
Biological: quantification of BRAF and NRAS mutation
Quantification of cell-free BRAF and NRAS mutations with digital PCR




Primary Outcome Measures :
  1. Quantify plasmatic BRAF and NRAS mutation determine by PCR digitale in µg/ml before treatment [ Time Frame: Day 0 ]
  2. Study the longitudinal monitoring of cell-free the kinetics of the plasma mutation of BRAF and NRAS mutation in µg/ml and comparing them with imaging (based on RECIST criteria) and with the activity of the lactate dehydrogenase in serum ( LDH) in U/l . [ Time Frame: Month 24 ]

Secondary Outcome Measures :
  1. Compare the results obtained by PCR digitale from the cell-free with the results on FFPE tissue samples [ Time Frame: Month 24 ]
  2. Identify genomic alterations and mutations of resistances in a restricted subgroup of patient by New Generation Sequencing analysis [ Time Frame: Month 24 ]
