Childhood Cancer

Cancer cases are defined using at least one hospital discharge diagnosis coded as ICD-10-GM C00-C97, excluding benign cancer diagnoses. Leukaemia was the most common cancer type in the cohort, followed by central nervous system tumours. There were 3,410 children diagnosed with cancer during cohort follow-up. The study relies on inpatient diagnoses for outcome definition because German childhood cancers are routinely managed in hospitals. Childhood cancer in Germany can cause long-term sequelae even though about 82% of affected children survive at least 15 years after diagnosis. Childhood cancer is the primary outcome for the PRECHIC project using the cohort. Weed the People focuses on families whose children have cancer and use cannabis oils with allopathic treatment. The featured families were selected because they retained Western oncology care and had oncologist support for cannabis use.
