HPV-based cervical cancer screening- facts, fiction, and misperceptions

Area of Science:

• Oncology
• Public Health
• Infectious Disease

Background:

• Randomized trials show human papillomavirus (HPV)-based cervical cancer screening surpasses cytology-based methods.
• Pooled analysis confirms reduced cervical cancer mortality with HPV screening.
• Global health systems are transitioning to HPV-based screening programs.

Purpose of the Study:

• To discuss controversies influencing HPV-based cervical cancer screening implementation.
• To review evidence on primary HPV testing efficacy and integration challenges.
• To highlight data gaps in optimal triage strategies for HPV-positive women.

Main Methods:

• Review of published data from clinical trials and large observational studies.
• Analysis of evidence supporting HPV-based screening efficacy.
• Discussion of implementation factors and controversies in diverse settings.

Main Results:

• Strong evidence supports HPV-based screening efficacy, with limited benefit from adding cytology.
• Optimal triage strategies for HPV-positive women require further research.
• Implementation varies based on cost, infrastructure, and risk perception.

Conclusions:

• HPV-based screening is highly effective for cervical cancer prevention.
• Further research is needed on triage strategies and integration with vaccination programs.
• Tailored implementation approaches are necessary for diverse healthcare settings.
