Evidence-based policy choices for efficient and equitable cervical cancer screening programs in low-resource settings

Area of Science:

• Public Health
• Oncology
• Global Health

Background:

• Cervical cancer disproportionately affects women in developing countries.
• Human papillomavirus (HPV) types 16 and 18 cause ~70% of cervical cancers.
• HPV vaccination is rolling out, but many women are beyond the target age.

Purpose of the Study:

• To describe challenges in cervical cancer screening programs in low-resource settings.
• To analyze tradeoffs between resource use and program effectiveness.
• To highlight opportunities for efficient and equitable screening programs.

Main Methods:

• Review of challenges in screening effectiveness, coverage, and management of screen-positive women.
• Summary of resource utilization and programmatic tradeoffs.
• Analysis of mathematical modeling informed by demonstration projects in India, Nicaragua, and Uganda.

Main Results:

• Identified key challenges in optimizing screening tests.
• Highlighted difficulties in achieving high screening coverage in target populations.
• Discussed complexities in managing women who screen positive for precancerous lesions.

Conclusions:

• Addressing screening challenges is vital for women not eligible for HPV vaccination.
• Efficient and equitable programming requires careful consideration of resource allocation.
• Mathematical modeling and demonstration projects offer insights for improving cervical cancer prevention in low-resource settings.
