Stool markers for colorectal cancer screening: future considerations

Area of Science:

• Gastroenterology
• Oncology
• Biomarker Discovery

Background:

• Stool screening for colorectal neoplasia offers noninvasive and affordable detection compared to other methods.
• Current stool screening methods require enhancement in sensitivity and specificity for improved diagnostic accuracy.
• The need for superior biomarkers in colorectal neoplasia screening is critical for early detection and patient outcomes.

Purpose of the Study:

• To propose a functional classification system for stool markers used in colorectal neoplasia screening.
• To provide a framework for considering and developing novel stool-based biomarkers.
• To enhance the understanding of marker entry into the gastrointestinal lumen for improved screening strategies.

Main Methods:

• A functional classification of stool markers was developed based on their mode of entry into the intestinal lumen.
• Literature review and conceptual analysis were employed to establish the classification framework.
• The proposed classification considers the biological and physiological pathways influencing marker presence in stool.

Main Results:

• A novel functional classification categorizes stool markers by their luminal entry mechanism.
• This classification provides a systematic approach to evaluating existing and potential stool markers.
• The framework highlights opportunities for developing more sensitive and specific screening tools.

Conclusions:

• The proposed functional classification of stool markers offers a novel perspective for improving colorectal neoplasia screening.
• This classification may guide the development of next-generation stool-based diagnostic tests.
• Enhanced stool screening markers are essential for advancing early detection of colorectal neoplasia.
