Application of Patient Navigation in Colorectal Cancer Screening: A Scoping Review.

Area of Science:

• Oncology
• Public Health
• Health Services Research

Background:

• Colorectal cancer incidence and mortality are increasing globally.
• Patient navigation is a proven strategy to enhance screening adherence.
• This review synthesizes evidence on patient navigation for colorectal cancer screening.

Purpose of the Study:

• To review the application of patient navigation in colorectal cancer screening.
• To provide an evidence-based foundation for future research and clinical practice.

Main Methods:

• Scoping review utilizing Arksey and O'Malley's framework.
• Comprehensive search of major scientific databases (PubMed, Embase, etc.).
• Inclusion of studies from database inception to May 20, 2025.

Main Results:

• 25 studies were included, featuring various navigator types and delivery methods (e.g., telephone, multi-modal).
• Navigation services covered education, barrier resolution, screening guidance, and follow-up.
• Patient navigation generally improved colorectal cancer screening adherence, with some heterogeneity in specific outcomes.

Conclusions:

• Patient navigation for colorectal cancer screening has a mature intervention framework.
• Optimization is needed for non-medical barriers and service content balance.
• Future interventions should be full-cycle, culturally adapted, and cost-effective.
