: Due to the observation period of our study (2000–2016) and the poor prognosis of the disease, patient informed consent could not be obtained. Considering these circumstances, the ethics committee of the medical faculty of Ludwig-Maximilians-University approved the use of anonymized patient data without obtaining the patients’ informed consent (project 20-081), and the study was carried out according to the Declaration of Helsinki.
