Detaljert beskrivelse
Screening specific molecular metabolic markers for medulloblastoma after radiotherapy can improve the prediction of clinical diagnosis and prognosis of patients.The purpose of this study is to validate the role of metabolite analysis in the diagnosis of pediatric medulloblastoma based on the analysis of body fluid samples by a new mass spectrometry system.Based on the metabolic markers found by screening, the pathogenic mechanism of metabolic pathway blockade was explained, and the scientific basis for later treatment was put forward.
