Serum biomarker tests show promise for improving colorectal cancer (CRC) screening adherence. Simple blood tests during routine check-ups could significantly boost patient participation in CRC screening programs.
Area of Science:
- Oncology
- Biomarker Research
- Public Health
Background:
- Colorectal cancer (CRC) remains a leading cause of cancer mortality globally.
- Screening programs have improved CRC mortality rates but face challenges due to poor patient adherence.
- Serum biomarker tests offer a potential solution to enhance CRC screening adherence.
Purpose of the Study:
- To review the literature on serum biomarkers for colorectal cancer and adenoma screening.
- To assess the potential of serum biomarker tests to improve patient adherence to CRC screening.
Main Methods:
- A systematic review of Medline-indexed articles on serum biomarkers for CRC screening published in the last 4 years.
- Searched non-Medline sources for CRC screening guidelines and practice patterns.
- Reviewed a total of 63 publications.
Main Results:
- Identified 51 Medline articles and 12 non-Medline articles relevant to serum biomarkers for CRC screening.
- Serum biomarker tests, requiring simple blood draws, are a promising approach.
- These tests have the potential to improve patient acceptance and adherence to CRC screening.
Conclusions:
- Serum biomarker tests represent a significant advancement in colorectal cancer screening.
- Simple blood-based tests can improve patient adherence and participation in CRC screening programs.
- Routine check-ups incorporating blood tests could enhance the effectiveness of CRC screening initiatives.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
