Implementation of HPV testing in Latin America

Area of Science:

• Oncology
• Public Health
• Infectious Diseases

Background:

• Cervical cancer remains a significant health burden for women in Latin America, largely due to challenges in implementing effective screening programs.
• Persistent infection with oncogenic human papillomavirus (HPV) is the primary cause of cervical cancer.

Purpose of the Study:

• To evaluate the feasibility and efficacy of implementing HPV testing for population-level cervical cancer screening in resource-constrained Latin American countries.
• To identify barriers and requirements for large-scale HPV screening implementation in the region.

Main Methods:

• Review of pilot programs in Nicaragua, Mexico, and Argentina assessing HPV testing and self-sampling.
• Analysis of experiences from El Salvador, Guatemala, Honduras, and Nicaragua in institutionalizing HPV testing.
• Assessment of regional opportunities, including existing screening programs and procurement mechanisms.

Main Results:

• Pilot programs demonstrated high efficacy in detecting precancerous cervical lesions, with good feasibility and acceptance of self-sampling.
• Several countries are actively moving towards population-level HPV testing implementation.
• Key challenges include updating guidelines, strengthening treatment capacity, and ensuring quality assurance for HPV testing.

Conclusions:

• Despite implementation challenges, significant opportunities exist in Latin America for successful HPV screening adoption.
• Existing government-funded programs and regional collaborations can facilitate the integration of HPV testing.
• Widespread adoption of HPV testing in national programs is anticipated within the next three to five years.
