Human Papillomavirus and Associated Cancers: A Review

Area of Science:

• Infectious Diseases
• Oncology
• Public Health

Background:

• Human papillomavirus (HPV) is the most prevalent sexually transmitted infection globally.
• Persistent HPV infections are a major cause of various cancers, including cervical, anal, and oropharyngeal cancers.
• Cervical cancer remains a leading cause of cancer mortality in women worldwide, with screening limitations in resource-poor settings.

Purpose of the Study:

• To highlight the global impact of HPV infections and the critical role of vaccination.
• To emphasize the disproportionate effect of HPV on individuals with HIV.
• To advocate for increased HPV awareness and vaccination access.

Main Methods:

• Review of existing literature on HPV epidemiology, disease burden, and vaccine efficacy.
• Analysis of factors contributing to low HPV vaccination uptake.
• Examination of HPV infection dynamics in immunocompromised populations.

Main Results:

• HPV infections are widespread, with persistent cases leading to significant cancer incidence.
• HPV disproportionately impacts individuals living with HIV, increasing cancer risk and mortality.
• The HPV vaccine demonstrates near-perfect efficacy in preventing cervical cancer when administered before sexual activity.

Conclusions:

• The HPV vaccine is a powerful tool for reducing HPV-related diseases and mortality.
• Low global vaccination rates, driven by access and knowledge gaps, hinder disease prevention.
• Enhanced public health initiatives focusing on HPV awareness and vaccination accessibility are crucial worldwide.
