: Cancer data were rendered anonymous using codes previous to analysis in accordance to French legislation. The cancer registry database was approved by the French Institutional Review Board for the protection of privacy and personal data of the French National authority (Commission Nationale Informatique et Libertés, CNIL N° 987 001). According to French legislation for population-based cancer registries, since our study did not involve direct patient contact for cancer survival analysis, additional approval from ethical committees for informed consent was not required. The need for written informed consent was waived by the French Institutional Review Board for the protection of privacy and personal data ethics committee due to the retrospective nature of the study. All methods were carried out in accordance with relevant guidelines and regulations.
