25 febbraio 2016 aggiornato da: Hoffmann-La Roche

Evaluation of Concordance Between the Methods Used in INCa Platforms and the Cobas® 4800 BRAF V600 Mutation Test for Detection of BRAF V600 Mutations in Melanoma in Real Life Setting

This non-interventional study will compare the Cobas BRAF V600 mutation assay with in-house methods used in molecular laboratories for the assessment of the BRAF mutation status in melanoma tumor samples. No patients will be enrolled in this study. Data will be collected for approximately 6 months.
