Emerging technologies in colorectal cancer screening

Area of Science:

• Gastroenterology
• Public Health
• Medical Technology

Background:

• Colorectal cancer (CRC) remains a significant public health concern with high mortality rates, largely due to low screening adherence.
• Current CRC screening methods face challenges including patient discomfort, lack of awareness, and procedural complexity, contributing to low screening rates.

Purpose of the Study:

• To evaluate emerging colorectal cancer screening technologies, specifically CT colonography (CTC) and stool DNA testing.
• To identify key areas for improvement and further research before widespread population-based implementation of these novel screening methods.

Main Methods:

• Review and discussion of the current status and future directions for CT colonography and stool DNA testing for colorectal cancer screening.
• Analysis of technical, logistical, and patient-centered factors influencing the adoption of new screening modalities.

Main Results:

• CT colonography and stool DNA testing are promising less invasive alternatives to current colorectal cancer screening procedures.
• Further advancements are needed in CTC accuracy, virtual preparation, availability, acceptability, and cost-effectiveness.
• Optimal molecular targets for stool DNA testing require further identification.

Conclusions:

• Novel screening technologies offer potential to improve colorectal cancer detection and reduce mortality.
• Addressing technical and practical challenges is crucial for successful population-based implementation of CT colonography and stool DNA testing.
• Future innovations, such as miniaturized endoscopic devices, may revolutionize colorectal cancer screening and management, aiming to make CRC a rare disease.
