Non Interventional German Leptomeningeal Disease Register

Once the patient or their legal guardian has given their written consent, a patient is included in the leptomeningeal disease register. Due to the rapid course of the disease and potential rapid deterioration, the documentation of the course of the disease of the individual patients is to be carried out retrospectively from the data recorded during the course of the clinical routine for the entire duration of the study or until the death of the participating patients after the written consent of the patients. The registry's data sources are the diagnostic findings made at the center and doctors' letters from routine clinical practice. The participating centers carry out the assessment of the participants' performance status so that the patients do not have to complete any study-related questionnaires.
