Eligibility Criteria:
Inclusion Criteria:
* patients who were newly diagnosed with CNS tumour admitted for in-patient treatments during period of Jan.1st 2016 to Dec. 31st 2017
* patients who were less than 18 year-old at diagnosis
* patients with available mandatory information as age, gender during enrollment
* patients must have pathological diagnosis of tumours, which followed 2016 edition of the World Health Organization (WHO) Classification of Tumours of the Central Nervous System (CNS), except the following conditions:
1. Diffuse Intrinsic Pontine Glioma (DIPG) according to classic symptoms and typical MRI
2. confirmed NF1 patients with classic symtoms and MRI representing Optic Pathway Glioma (OPG) with no surgical treatment indications will be marked as "pilocytic astrocytoma"
3. patients with newly diagnosed recurrence or metastasis of previously confirmed (before Jan.1st 2016) Embryonal Tumours (medulloblastoma, emryonal tumour with multilayered rosettes - C19MC altered, atypical teratoid / rhabdoid tumour / others) and high grade gliomas (glioblastoma, anaplastic astrocytoma) that were unwilling to recieve second surgical treatment / inoperable / without surgical indication, will be marked as original diagnosis
4. patients with newly diagnosed relapse of previously confirmed (before Jan.1st 2016) low grade glioma (defined as pilocytic astrocytoma, diffuse astrocytoma, pilomyxoid astrocytoma, pleomorphic xanthoastrocytoma, subependymal giant cell astrocytoma, oligodendroglioma, oligoastrocytoma, ganglioglioma, desmoplastic infantile astrocytoma and ganglioglioma, dysembryoplastic neuroepithelial tumour, papillary glioneuronal tumour, rosette-forming glioneuronal tumour of the fourth ventricle, angiocentric glioma, dysplastic cerebellar gangliocytoma, extraventricular neurocytoma, cerebellar liponeurocytoma, and central neurocytoma) and ependymal tumours in cross-sectional period, who were unwilling to be operated / inoperable / without surgical indication, will be marked as original diagnosis
* clinical, image and pathology data of patients with unidentified pathological diagnosis from member sites of CNOG-MC001 collaborative group will be sent to study center for reviewing; cases with unidentifiable diagnosis after center review and alignment with CNOG-MC001 sites will be marked as "unknown"
Exclusion Criteria:
* confirmed CNS metatasis patients whose tumour tissues were obtained from other systems other than CNS will be excluded
* patients with newly diagnosed recurrence or metastasis of previously confirmed CNS Tumours, will be excluded when primary tumour diagnosis and progression time points were both in cross-sectional period; these patients will be only enrolled as "newly diagnosed cases with primary tumours" and recorded as "progressed in follow-up" in follow-up data sheet
* patients with newly diagnosed relapse of previously confirmed (before Jan.1st 2016) low grade glioma and ependymal tumours, who were unwilling to be operated / inoperable, and were suspected as malignant transformation, will be excluded due to lack of pathological diagnosis
* patients with insufficient or inconsistant data (e.g: patient diagnosed with primary medulloblastoma with tumour located in cerebral) will be excluded in center review after consulting with data-upload institutions
