Study Title | NMR-based Metabolomics for CRC Diagnosis |
Study Type | Disease Diagnosis |
Study Summary | Despite the fact that colorectal cancer (CRC) is one of the most prevalent and deadly cancers in the world, the development of improved and robust biomarkers to enable screening, surveillance, and therapy monitoring of CRC continues to be evasive. In particular, patients with colon polyps are at higher risk of developing colon cancer; however, noninvasive methods to identify these patients suffer from poor performance. In consideration of the challenges involved in identifying metabolite biomarkers in individuals with high risk for colon cancer, we have investigated NMR-based metabolite profiling in combination with numerous demographic parameters to investigate the ability of serum metabolites to differentiate polyp/CRC patients from healthy subjects. We also investigated the effect of disease risk on different groups of biologically related metabolites. Our study may explain some of the challenges and promise a novel avenue for future metabolite profiling methodologies. |

Collection ID: | CO000299 |
Collection Summary: | Serum samples from patients with CRC, polyps, and matched healthy controls were obtained from the Indiana University School of Medicine. Following the IRB protocol approved by both Indiana and Purdue Universities, patients undergoing colonoscopy for CRC screening were evaluated and blood from the consented patients was obtained after overnight fasting and bowel preparation but prior to colonoscopy. Blood samples were allowed to clot at room temperature for 45 min and then centrifuged at 2000 rpm for 10 min. The sera were collected, and aliquoted into separate vials, then transported to Purdue University over dry ice and stored at -80°C until used for analysis. |
