This study examined the epidemiology of childhood central nervous system tumors at Queensland Children's Hospital, providing insight into the incidence and presenting features in an Australian population. The study demonstrated a shorter symptom interval compared to previous literature, with the most frequent tumors located in the posterior fossa.
Within Australia, there is little epidemiologic information regarding paediatric central nervous system (CNS) tumours. This study examined the epidemiology of childhood CNS tumours at Queensland Children's Hospital (QCH), the major paediatric referral centre for Queensland and northern New South Wales. We assessed the data from 221 newly diagnosed childhood CNS tumours across a five-year period from 2015 to 2019. Recurrent tumours were excluded. Data was collected on patient age, gender, histopathological diagnosis, tumour grade, anatomical site, and residential geographical location. The incidence within this period ranged from 2.65 to 3.85 cases per 100,000 children. The median symptom interval was 30 days (IQR 14-122) with presenting features similar to previous studies. The symptom interval was shorter for children zero to three years compared to children four years or older. The most frequent tumour was pilocytic astrocytoma, followed by medulloblastoma and Langerhans cell histiocy-tosis. The posterior fossa was the most frequent anatomical location for tumours. Our study demon-strated a shorter symptom interval in comparison to previous literature. The study was able to determine the incidence and presenting features within an Australian population.
