HPV Testing and its Role in Cervical Cancer Screening

Area of Science:

• Oncology
• Virology
• Public Health

Background:

• Persistent carcinogenic human papillomavirus (HPV) infection is essential for cervical precancer and cancer development.
• HPV testing is now integrated into cervical cancer screening, offering higher sensitivity than cytology.
• Most HPV infections are transient, necessitating triage tests to identify individuals requiring colposcopy.

Purpose of the Study:

• To provide a foundation for understanding HPV's role in cervical carcinogenesis.
• To discuss the implementation of HPV testing and triage in cervical cancer screening and management.
• To address cervical cancer disparities, particularly in the United States.

Main Methods:

• Review of HPV biology, natural history, and epidemiology.
• Detailed discussion of HPV-based testing and triage strategies.
• Summarization of triage tests: cervical cytology, HPV genotyping, p16/Ki-67 dual stain, and HPV/methylation markers.

Main Results:

• HPV testing demonstrates superior sensitivity for detecting cervical precancer compared to cytology.
• Triage tests are essential to manage HPV-positive individuals and prevent unnecessary colposcopies.
• Cervical cancer disparities persist, especially within the United States.

Conclusions:

• HPV testing significantly enhances cervical cancer screening efficacy.
• Effective triage strategies are vital for accurate risk stratification and patient management.
• Addressing disparities is crucial for equitable cervical cancer prevention and control.
