Investigating DNA changes in colorectal cancer patients

Novel DNA Adductomics Methodological Developments for Research in Colon Cancer

Observational University of Copenhagen · NCT04865601

This study is trying to find out if certain DNA changes in colon tissue and other samples can help us understand why some people get colorectal cancer.

What this trial studies

This project aims to identify DNA adducts in colon tissue from patients with colorectal cancer (CRC) who are scheduled for colon resections, as well as from control patients undergoing similar procedures. The study will also analyze surrogate samples such as white blood cells, blood plasma, and urine for DNA-repair products. By utilizing advanced high-resolution mass spectrometry, the research seeks to understand the genetic modifications associated with increased CRC risk, particularly focusing on sporadic cases and hereditary conditions like Lynch syndrome and familial adenomatous polyposis. This approach aims to fill the knowledge gap regarding the relationship between DNA adducts and CRC development.

Who should consider this trial

Good fit: Ideal candidates include patients with familial adenomatous polyposis, Lynch syndrome, hereditary non-polyposis colorectal cancer, sporadic colorectal cancer, or ulcerative colitis who are scheduled for colon resection.

Not a fit: Patients under 18 years of age or those who have recently donated blood may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of the genetic factors contributing to colorectal cancer, potentially guiding prevention and treatment strategies.

How similar studies have performed: Previous studies have identified DNA adducts in colorectal cancer using older technologies, but this study employs a novel approach with advanced mass spectrometry, making it a potentially groundbreaking investigation.
