Untargeted ultra‑high‑resolution mass spectrometry metabolomic profiling of blood serum in bladder cancer
September 2022
Abstract
This study reports an untargeted analysis of human serum using ultra‑high‑resolution mass spectrometry coupled with ultra‑high‑performance liquid chromatography. A total of 200 samples (100 bladder cancer patients, 100 controls) were evaluated. The study identified metabolites whose abundances varied significantly across different tumor stages and grades. The authors found 37 serum metabolites that distinguish between low- and high-grade disease. These results suggest that serum metabolite profiling may offer a non‑invasive diagnostic and monitoring tool for bladder cancer
