Brief Summary:
Circulating tumor DNA detection and quantification in patients with metastatic choroidal melanoma.

Condition or disease Intervention/treatment Phase
Choroidal Melanoma, Diffuse Biological: Blood sampling Not Applicable

Detailed Description:

Technique development: In first step, the different available techniques will be evaluated for specificity and sensibility using serial dilutions of cell lines with or without GNAQ mutation.

Validation: The tumor DNA detection rate will be estimated from metastatic uveal patient's blood. The investigators will study 40 patients to obtain at least 15 patients bearing a GNAQ mutation in the primitive tumor or in metastasis. With those 15 patients, the investigators will determinate the most sensitive technique and the best cost/efficiency ratio.

Study Type : Interventional  (Clinical Trial)

Arm Intervention/treatment
Blood sampling Biological: Blood sampling
30ml of patient peripherical blood will be collected

Primary Outcome Measures :
  1. Assessment and development of circulating tumor DNA detection techniques [ Time Frame: 2 years ]
    Quantification of circulating tumor DNA in blood samples. Results expressed in number of samples where circulating DNA is present.

Secondary Outcome Measures :
  1. Detection technique comparison (PAP (pyrophosphorolysis activated polymerisation), BEAMing, NGS(next sequencing generation)) in terms of feasibility, robustness, sensitivity and cost. [ Time Frame: 2 years ]
    The methods of detection which will be used such as the BEAMing, the PAP (Pyrophosphorolysis-activated polymerization) and NGS (next sequencing generation)is techniques of a big specificity capable of detecting a mutant copy among 1.104 wild copies for the BEAMing, 2.109 for the PAP and 1.105 for the NGS. The sensibility of these techniques is limited by the quantity of genomic DNA which we can extract from the sample of blood.
