Major Research Findings
Human papillomavirus (HPV)-related diseases are a significant health problem worldwide, particularly in developing countries. 5 notes that surgical excision has been the standard treatment for these diseases. However, the authors question why surgery is the standard treatment for other clinically evident, virally mediated diseases. They review prevention, chemoprevention, and vaccine trials for the prevention and treatment of HPV-related diseases of the genital tract. The review highlights significant advancements in the last decade, suggesting promising non-surgical options for patients with cervical dysplasia and other HPV-associated diseases.
15 investigates the effectiveness of topical cidofovir and imiquimod in treating vulvar intraepithelial neoplasia (VIN). The study found that these treatments are effective in approximately 55% of patients, reducing the need for surgery. Furthermore, HPV E2 gene methylation has been identified as a predictor of response to treatment, though methylation measurements are only obtainable in about 50% of patients.
14 presents a randomized clinical trial (ORATOR2) comparing radiotherapy (RT) and transoral surgery (TOS) for HPV-related oropharyngeal squamous cell carcinoma (OPSCC). The trial found that TOS had an unacceptably high risk of grade 5 toxic effects, leading to the discontinuation of accrual. While both treatment arms achieved good swallowing outcomes at 1 year, long-term follow-up is necessary to assess overall survival (OS) and progression-free survival (PFS) outcomes.
10 explores the use of the bivalent HPV vaccine for recalcitrant common warts, comparing intramuscular and intralesional injection methods. The study found that intralesional injection led to complete clearance of warts in 81.8% of patients, compared to 63.3% in the intramuscular group, although the difference was not statistically significant. Both methods were well-tolerated, with no reported recurrences.
4 examines the efficacy and safety of low-dose oral isotretinoin for recalcitrant condylomata acuminata (RCA) of the cervix. A randomized, placebo-controlled trial found that isotretinoin was significantly more effective than placebo in treating RCA, with a low recurrence rate and manageable side effects.
11 presents a meta-analysis investigating the prophylactic effect of HPV vaccination following conization for high-grade cervical intraepithelial neoplasia (CIN 3). The analysis showed that HPV vaccination significantly reduced the risk of developing recurrent CIN 2+ after surgical excision, regardless of HPV type. The number needed to vaccinate (NNV) to prevent one case of recurrent CIN 2+ was estimated to be 45.5.
2 examines the predictive factors for successful treatment of genital HPV lesions with systemic interferon alpha-2b. The study found that detectable diagnostic phase levels of serum antibodies to HPV16 open reading frame (ORF) E2 derived peptide were associated with a 10-fold difference in the risk of recurrence of HPV infection following adjuvant interferon alpha-2b therapy, suggesting that evaluating E2 antibody responses may help identify patients who would respond to systemic interferon treatment.
7 reviews the potential of HPV vaccination as an adjuvant treatment for individuals with HPV-related clinical disease. The review suggests that vaccination could be a valuable addition to traditional therapies.
1 compares carbon dioxide laser treatment with and without adjuvant interferon alpha-2b for genital HPV infection. While complete response was similar in both groups, the study found that interferon alpha-2b treatment was more effective in reducing recurrence among patients infected with HPV 16/18.
9 reviews the use of HPV vaccines for treating HPV-related dysplastic and neoplastic conditions. The review found that the commercially available quadrivalent HPV vaccine is a potential therapeutic option for cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas. Non-commercially available HPV vaccines have shown promise in treating anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia. The review highlights the need for further research on the efficacy of HPV vaccines as adjunctive therapy for HPV-associated cutaneous and/or mucosal disease.
6 reports on a Phase I clinical trial evaluating the safety and immunogenicity of GTL001, a therapeutic vaccine for women infected with HPV16 or 18 with normal cervical cytology. The trial demonstrated the tolerability and immunogenicity of GTL001, offering hope for preventing high-grade lesions in HPV-infected women.
12 analyzes the impact of HPV-16/18 AS04-adjuvanted vaccine on preventing subsequent infection and disease after excision treatment. While HPV prophylactic vaccines are acknowledged to be effective in HPV-naive individuals, the study suggests that HPV vaccination may also benefit individuals who have undergone surgery for cervical disease.
3 reviews the efficacy of treatments for subclinical cervical HPV infection without intraepithelial neoplasia. The review found that none of the clinical trials evaluated demonstrated significant differences between the experimental and control groups, suggesting that effective treatments for subclinical HPV infection without intraepithelial neoplasia are currently lacking.
16 explores the efficacy of HPV vaccination on HPV infection and the recurrence of HPV-related diseases after local surgical treatment through a systematic review and meta-analysis. The analysis suggested that HPV vaccination might reduce the risk of CIN recurrence, especially for HPV16 or 18-related cases, in women treated with local excision. However, the quality of evidence was inconclusive, and large-scale randomized controlled trials are needed to confirm the effectiveness and cost-effectiveness of HPV vaccination in women undergoing treatment for HPV-related diseases.
13 reviews the potential of HPV vaccination as a therapeutic approach for ano-genital warts, drawing on previous case reports. The study suggests that HPV vaccination could be a promising therapeutic option for managing these lesions. However, randomized prospective trials are needed to evaluate the efficacy, safety profile, and effects of HPV vaccination for treating ano-genital warts, and formal approval and an off-label indication for this use are needed.
Treatment Summary
Research has explored various treatments for HPV-related diseases, including topical cidofovir and imiquimod for VIN, radiotherapy and transoral surgery for OPSCC, bivalent HPV vaccine injection (intramuscular and intralesional) for recalcitrant common warts, oral isotretinoin for RCA of the cervix, systemic interferon alpha-2b therapy with laser ablation, and prophylactic HPV vaccination after conization.
