: This study was assessed and approved by the scientific and privacy committee of PALGA (the nationwide network and registry of histo- and cytopathology in the Netherlands) and the monitory board of the Netherlands Cancer Registry (NCR). As this study was performed retrospectively on anonymised data, and did not involve subjecting patients to anything, consent from the ethics committee was not required according to the Dutch law. We only ever received fully anonymised data. Data of patients who object against the scientific use of their (anonymised) data are not included in the PALGA database. Therefore waiver of informed consent is applicable. All data were retrieved and handled in compliance with the General Data Protection Regulation (GDPR).
