Brief summary
Metabolomics is a complementary approach for identifying perturbed metabolic pathways. The goal of this study is to establish and validate an early diagnostic model for bladder cancer by metabolomics.
Detailed description
Early diagnosis and life-long surveillance are clinically important to improve the long-term survival of bladder cancer patients. Currently, a noninvasive biomarker that is as sensitive and specific as cystoscopy in detecting bladder cancer is lacking. Metabolomics are small organic molecules (below 2000 mass units) that are products of complex pathways. This is a prospective study aims to create an early diagnostic model based on serum and urine metabolomics. Commonly employed metabolomics analytical platforms include nuclear magnetic resonance spectroscopy (NMR), gas chromatography mass spectrometry (GC-MS), and liquid chromatography mass spectrometry （LC-MS）. The diagnostic model will be made to distinguish bladder cancer and benign disease of the urinary system.
