: The study was conducted in accordance with the ethical principles for medical research involving human subjects developed in the Declaration of Helsinki by the World Medical Association (WMA). The study received approval in France from the National Ethics Committee CCTIRS (N°909226, and 16.628) and the National Committee for Protection of Personal Data CNIL (N°09–203, derogation N°913466). Although consent for participation is usually required, we requested derogation from the CNIL in light of the very low survival rates for this pathology. The derogation was accepted, and therefore, the need for participant consent has been waived. Nevertheless, administrative permissions from the CCTIRS and CNIL were required to access the raw data used in this study. The data used in this study was anonymised before its use.
