This study aimed to profile paralleled metabolites of CRC tissues and adjacent non-cancerous tissues alongside pre- and post-operative stools from the same patients, to investigate how fecal metabolomic phenotypes correlate with the tumor tissue especially in a molecular pathology context. Our patient-matched cohort revealed a few overlapping discriminatory metabolites between the CRC and stool metabolomes, indicating the networks for metabolic pathway aberrations across both matrices. The altered metabolites potentially involved in the disruption of normal bacterial ecology, malabsorption of nutrients, increased glycolysis, TCA cycle and glutaminolysis, implying a Warburg effect for cell energy production required for rapid proliferation
