Abstract

The invention relates to a metabolic marker of medulloblastoma in urine and application of the metabolic marker. Specifically, the invention relates to application of a reagent for detecting the levelof metabolite in urine of a subject in preparation of a kit and / or a chip for diagnosis and / or prognosis of myeloblastoma, wherein the metabolite is selected from one or more of the following substances: urothiopterin, 20-oxo-leukotriene E4, cortolone and tetrahydrocortisone.

Description

technical field [0001] The invention relates to the field of biotechnology, and more specifically relates to a metabolic marker of medulloblastoma in urine and its use in early diagnosis and postoperative condition monitoring. Background technique [0002] Medulloblastoma (MB) is the most common malignant central nervous system tumor in children (see Brandes, A.A. and M.K.Paris, Review of the prognostic factors inmedulloblastoma of children and adults. Crit Rev Oncol Hematol, 2004.50(2): p.121-8; Saran, F., Recent advances in pediatric neuro-oncology. Curr OpinNeurol, 2002.15(6): p.671-7), accounting for 8% to 10% of children's brain tumors (see Archer, T.C., E.L. Mahoney, and S.L. Pomeroy, Medulloblastoma: Molecular Classification-Based Personal Therapeutics. Neurotherapeutics, 2017.14(2):p.265-273). Early detection and early treatment can effectively improve the five-year survival rate of patients (see Ramaswamy, V. et al., Recurrence patterns across medulloblastoma subgr...
