Exploring the Value of Urine Proteomics-based Dynamic Surveillance for Early Recurrence After Radical Surgery for Hepatocellular Carcinoma: a Prospective Cohort Study

Patients with hepatocellular carcinoma amenable to radical resection were included according to the inclusion exclusion criteria, and preoperative urine and postoperative urine from consecutive patients were collected at the marker time (before receiving postoperative adjuvant therapy after radical surgery for hepatocellular carcinoma) and at the longitudinal time (at the time point of 3 months after radical surgery), and the different samples were preprocessed, followed by mass spectrometry-based urinary proteomics to detect the differences in urinary proteins, and the data were recorded to compare the differences.
