Cervical Cancer Screening in Resource-Constrained Countries: Current Status and Future Directions

Area of Science:

• Oncology
• Public Health
• Epidemiology

Background:

• Cervical cancer remains a significant global health burden, particularly in developing countries.
• Ineffective screening programs are hampered by limitations in current modalities and lack of accessible, cost-effective tools.
• Cytology adoption is often infeasible due to inadequate infrastructure and trained personnel in resource-limited settings.

Approach:

• This review examines current cervical cancer screening strategies, focusing on their applicability in low-resource environments.
• It evaluates the strengths and limitations of cytology, visual inspection, and Human Papillomavirus (HPV) testing.
• The role of novel HPV detection methods (DNA, RNA, protein-based) for triaging screen-positive individuals is discussed.

Key Points:

• Recent advancements include low-cost HPV test kits and India's development of a large-scale screening framework.
• HPV vaccination offers primary prevention but faces challenges in availability and acceptability in developing nations.
• The impact of HPV vaccination on screening test characteristics requires further evaluation.

Conclusions:

• India's operational framework guidelines for population-based cervical cancer screening offer a potential model for resource-constrained regions.
• Implementing effective screening and vaccination strategies is crucial for cervical cancer control in developing countries.
• Continued research is needed to optimize screening and address vaccination challenges in diverse settings.
