MITF and neoplasm: As the length of the follow-up time in the TCGA data, as used by Phelps et al. [27], is limited, and we have the possibility of analysing a patient cohort with mRNA expression and chromosome data with over ten years of follow-up, we set out to determine whether MITF expression was associated with survival in our cohort and whether it was related to prognostic factors, with the tumour’s chromosome status in particular.
