Human papillomavirus-associated diseases

Area of Science:

• Oncology
• Virology
• Public Health

Background:

• Human papillomavirus (HPV) infections are associated with a range of benign and malignant conditions affecting oral, genital, and cutaneous areas.
• Sexually transmitted alpha-HPV types, particularly HPV 16 and 18, show the strongest association with cervical cancer, with viral DNA found in nearly all such malignancies.

Purpose of the Study:

• To review the association of human papillomavirus (HPV) with various cancers and benign conditions.
• To highlight the effectiveness of cervical cancer screening and the limitations in early detection for other HPV-associated disorders.
• To emphasize the role of HPV vaccination in disease prevention.

Main Methods:

• Literature review of HPV-associated conditions.
• Analysis of the public health impact of different HPV types.
• Evaluation of current screening and prevention strategies for HPV-related diseases.

Main Results:

• The link between HPV and cervical cancer is well-established, with high viral DNA presence in malignancies.
• The contribution of cancer-causing HPV types to other anogenital, oral, and oropharyngeal cancers, and benign disorders, is less significant.
• Cervical cytologic screening enables early detection and treatment of precancerous lesions, a capability lacking for most other HPV-associated conditions.

Conclusions:

• HPV vaccination is the sole preventive measure against the majority of HPV-related diseases.
• Early detection of precancerous lesions is challenging for conditions beyond cervical cancer.
• Understanding HPV's role in various pathologies is crucial for targeted public health interventions.
