From the Guidelines
The most effective treatment for HPV is prevention through vaccination, specifically with the 9-valent HPV vaccine (Gardasil 9), which protects against the most common cancer-causing HPV types and is recommended for preteens aged 11-12, though it can be given through age 45. There is no specific treatment for the human papillomavirus (HPV) infection itself, as most HPV infections clear on their own within 1-2 years through the body's immune system 1. However, treatments are available for the health problems that HPV can cause. For genital warts caused by HPV, options include topical medications like imiquimod (Aldara, Zyclara), podofilox (Condylox), or trichloroacetic acid (TCA) 2. These are typically applied directly to warts for several weeks. Alternatively, healthcare providers can remove warts through cryotherapy (freezing), electrocautery (burning), laser treatment, or surgical excision.
For precancerous cervical lesions or other HPV-related cancers, treatments may include loop electrosurgical excision procedure (LEEP), cryotherapy, laser therapy, or surgery depending on the severity 3. Regular screening with Pap tests and/or HPV testing is essential for early detection of cervical abnormalities before they develop into cancer 4. The 9-valent HPV vaccine (Gardasil 9) has been shown to be highly effective in preventing HPV-related cancers and is recommended for routine vaccination of preteens aged 11-12, with catch-up vaccination available through age 45 5.
Some key points to consider:
- The HPV vaccine is most effective when administered before sexual contact 1
- The 9-valent HPV vaccine (Gardasil 9) protects against the most common cancer-causing HPV types and is recommended for preteens aged 11-12, though it can be given through age 45 5
- Regular screening with Pap tests and/or HPV testing is essential for early detection of cervical abnormalities before they develop into cancer 4
- Treatments are available for the health problems that HPV can cause, including genital warts and precancerous cervical lesions or other HPV-related cancers 2, 3
From the FDA Drug Label
Imiquimod has no direct antiviral activity in cell culture A study in 22 subjects with genital/perianal warts comparing imiquimod cream and vehicle shows that imiquimod cream induces mRNA encoding cytokines including interferon-ɑ at the treatment site. In addition HPVL1 mRNA and HPV DNA are significantly decreased following treatment.
The treatment for HPV (Human Papillomavirus) using Imiquimod Cream involves applying the cream to the affected area, which can help reduce the viral load by inducing the production of cytokines, including interferon-ɑ. Key points to consider:
- Application frequency: Apply Imiquimod Cream 3 times per week to external genital/perianal warts.
- Treatment duration: Continue treatment until total clearance of the genital/perianal warts or for a maximum of 16 weeks.
- Mechanism of action: Although the exact mechanism is unknown, Imiquimod Cream has been shown to decrease HPVL1 mRNA and HPV DNA in treated areas 6, 7.
From the Research
Treatment for HPV
- The primary method of prevention for HPV is vaccination, with the nonavalent HPV vaccine being effective in preventing high-grade precancerous cervical lesions in noninfected patients 8.
- Screening for HPV infection is effective in identifying precancerous lesions and allows for interventions that can prevent the development of cancer 8.
- Loop electrosurgical excision procedure (LEEP) is a common treatment for cervical intraepithelial neoplasia grade 2 or 3 (CIN2+) 9, 10, 11.
- HPV testing following LEEP can identify women at risk for posttreatment cervical intraepithelial neoplasia grade 2 or 3 disease 9.
- A negative high-risk HPV test can be considered a reliable test of cure, with a negative predictive value for HSIL of 100% (95% CI 99.8-100%) 11.
- HPV load can be used to predict residual disease after cone biopsy, with high HPV load being a more accurate predictor for CIN2-3 residual disease 12.
Follow-up Care
- Follow-up care after LEEP or cone biopsy typically involves HPV testing and cytology to detect residual or recurrent disease 9, 10, 11, 12.
- Combination testing using HPV and cytology can be useful in post-LEEP management strategies, with high sensitivity and specificity for detecting posttreatment CIN2+ 9.
- Negative co-testing 6 months after LEEP can be considered a reliable test of cure, with consistent results at 3-year follow-up 11.
