Use of risk-based cervical screening programs in resource-limited settings

Area of Science:

• Oncology
• Public Health
• Global Health

Background:

• Cervical cancer disproportionately affects resource-limited settings.
• Current screening and management are often unavailable in these areas.
• A risk-based approach is standard in high-resource settings.

Purpose of the Study:

• To describe a conceptual model for optimizing cervical cancer screening and management in resource-limited settings.
• To adapt a risk-based approach for effective implementation in areas with limited resources.

Main Methods:

• Utilizing a risk-based framework for screening and management.
• Employing HPV testing with self-sampling for accessibility.
• Incorporating HPV genotyping for enhanced risk stratification.
• Exploring automated visual evaluation with artificial intelligence for improved risk assessment.

Main Results:

• The model ensures screening methods effectively differentiate low-risk from high-risk individuals.
• Resources are directed towards populations with the highest cancer risk.
• HPV testing and genotyping improve risk stratification for targeted treatment.

Conclusions:

• A risk-based approach can optimize cervical cancer prevention in resource-limited settings.
• Focusing triage and treatment on high-risk patients maximizes resource efficiency.
• Minimizing interventions for low-risk patients conserves valuable resources.
