Adjuvant Human Papillomavirus Vaccination After Excisional Procedure for Cervical Intraepithelial Neoplasia, A Cost-effectiveness Analysis

(Abstracted from Obstet Gynecol 2023;141:756–763) A precursor to one of the most common cancers in the world and the United States and worldwide (cervical malignancy) is cervical intraepithelial neoplasia (CIN). Because the causal agent is known to be human papillomavirus (HPV), a primary prevention method of HPV vaccination is universally recommended for individuals 9 to 26 years of age and is not universally recommended but is approved for individuals aged 27 to 45 years.

Human papillomavirus vaccination receipt and provider counseling rates among high-risk patients.

We describe provider documented counseling patterns and perception regarding HPV vaccination among patients with a history of cervical dysplasia. All patients ages 21-45 who underwent colposcopy at a single academic medical center from 2018 to 2020were sent a self-administered survey through the electronic medical record patient portal to assess their attitudes regarding human papillomavirus (HPV) vaccination. Demographic information, HPV vaccination history, and documented obstetrics and gynecology provider counseling at the time of colposcopy were examined. Of 1465patients, 434 (29.6%) reported or had documented receipt of at least one dose of the human papillomavirus vaccine. The remainder reported they were not vaccinated or had no documentation of vaccination. Proportion of vaccinated patients was higher among White compared to Black and Asian patients (P=0.02). On multivariate analysis, private insurance (aOR 2.2, 95% CI 1.4-3.7) was associated with vaccinated status while Asian race (aOR 0.4, 95% CI 0.2-0.7) and hypertension (aOR 0.2, 95% CI 0.08-0.7) were less likely to be associated with vaccination status. Among patients with unvaccinated or unknown vaccination status, 112 (10.8%) received documented counseling regardingcatch-up human papillomavirus vaccination at a gynecologic visit. Patients seen by a sub-specialist obstetrics and gynecologic provider were more likely to have documented provider counseling regarding vaccination compared to those seen by a generalist obstetric/gynecologist provider (26% vs 9.8%, p<0.001). Patients cited lack of physician discussion (53.7%) and the belief that they were too old to receive the HPV vaccine (48.8%) as the main reasons for remaining unvaccinated. HPV vaccination and the rate of obstetric and gynecologic provider counseling regarding HPV vaccination among patients undergoing colposcopy remains low. When surveyed, many patients with a history of colposcopy cited provider recommendation as afactor in their decision to undergo adjuvant HPV vaccination, demonstrating the importance of provider counseling in thisgroup.

ASCCP Committee Opinion: Adjuvant Human Papillomavirus Vaccine for Patients Undergoing Treatment for Cervical Intraepithelial Neoplasia.

Individuals treated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+) are at long-term risk of persistent or recurrent disease despite treatment. This committee opinion aims to summarize and provide evidence-based recommendations for adjuvant human papillomavirus (HPV) vaccination based on available, published literature. A task force from the ASCCP Practice Committee reviewed current Centers for Disease Control and Prevention (CDC) guidelines and previously published literature about the role of adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+ and other HPV-related diseases. Current CDC guidelines recommend routine or catch-up HPV vaccination for individuals aged 9 to 26 years, and shared decision making regarding vaccination for individuals aged 27 to 45 years. Multiple published studies suggest a possible benefit for adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+. The American Society for Colposcopy and Cervical Pathology recommends adherence to current CDC recommendations for vaccination of individuals aged 9 to 26 years and consideration of the possible benefit of adjuvant HPV vaccination during shared decision making for previously unvaccinated individuals aged 27 to 45 years who are undergoing treatment for CIN2+.

Can Adjuvant HPV Vaccination Be Helpful in the Prevention of Persistent/Recurrent Cervical Dysplasia after Surgical Treatment?-A Literature Review.

Simple SummaryPrimary prophylactic, early detection and the treatment of precancerous lesions are the main goals of cervical cancer screening. Despite effective surgical treatment methods, using loop electrosurgical excision procedures and conization, the overall risk of the recurrence of HSIL lesions remains at approximately 6.6%. There is increasing evidence of the potential role of HPV vaccines in the adjuvant setting and their impact on the reduction of disease recurrence. This review aims to analyze the up-to-date research concerning the use and efficacy of secondary human papilloma virus (HPV) vaccination as an adjuvant method to surgical treatment in patients diagnosed with cervical HSILs.Cervical cancer formation is preceded by precursor lesions, including low-grade squamous intraepithelial lesions (LSILs) and high-grade squamous intraepithelial lesions (HSILs), which are usually diagnosed in women of reproductive age. Despite the recent advanced diagnostic and treatment methods, including colposcopy, the loop electrosurgical excision procedure (LEEP), and surgical conization, the recurrence or residual disease affects as many as 6.6% of patients. The lesions are often associated with human papilloma virus (HPV) infection. As HPV persistence is the leading and only modifiable factor affecting the risk of progression of CIN lesions into high-grade cervical dysplasia and cancer, it has been proposed to conduct adjuvant vaccination in patients treated for high-grade cervical dysplasia. To date, no vaccine has been approved for therapeutic use in patients diagnosed with HSILs; however, attempts have been made to determine the use of HPV prophylactic vaccination to reduce recurrent HSILs and prevent cervical cancer. The aim of this review was to analyze the up-to-date literature concerning the possible use of secondary human papilloma virus (HPV) vaccination as an adjuvant method to surgical treatment in patients diagnosed with cervical HSILs. Adjuvant HPV vaccination after surgical treatment may reduce the risk of recurrent cervical dysplasia.

Vaccination against human papillomavirus after adjuvant therapy of cervical intraepithelial neoplasia

Background. The relevance of the problem is supported by the lack of effective secondary prevention measures against human papillomavirus (HPV)-associated cervical intraepithelial neoplasia (CIN) and cervical cancer. The only currently verified treatment for lower genital neoplasia is destructive therapy, with the recurrence rate of viral infection remaining quite high even after such interventions. The preventive role of HPV vaccine at pre-existing cervical lesions is actively debated worldwide, but the evidence remains scattered and contradictory. The present study surveys the scientific publications available that evaluate the efficacy of human papillomavirus vaccination as a secondary prevention measure against related cervical pathology.Objectives. An evidence survey on the efficacy of adjuvant vaccination against human papillomavirus in patients undergoing destructive therapy for cervical intraepithelial neoplasia.Methods. We have conducted a 10 year-depth review of scientific literature on the adjuvant human papillomavirus (HPV) vaccination efficacy for reducing the recurrence risk of precancerous cervical neoplasia. The results are presented in form of the difference of mean or pooled 95% confidence-interval odds ratios (OR; 95% CI). Statistical analyses were conducted with Review Manager v. 5.4 (The Cochrane Collaboration, 2020).Results. Thirteen Russian- and English-language studies were selected for final analysis. A total of 21,702 cervical dysplasia patients were included: 5,941 (27.4%) received a perioperative HPV vaccine, while 15,761 (72.6%) only had surgical treatment. Recurrences of CIN I (mild cervical intraepithelial neoplasia; OR 0.45, 95% CI 0.27–0.73; p = 0.001) and CIN II (moderate cervical intraepithelial neoplasia; OR 0.33, 95% CI 0.20–0.52; p &lt;0.0001) were lower in the vaccinated vs. unvaccinated cohort.Conclusion. Adjuvant HPV vaccination associates with a lower risk of recurrence in cervical intraepithelial neoplasia. Further research is necessary to shed more light on the role of human papillomavirus vaccination as a secondary prevention measure against its associated lesions.

HPV Vaccination after Primary Treatment of HPV-Related Disease across Different Organ Sites: A Multidisciplinary Comprehensive Review and Meta-Analysis.

Objective: To assess evidence on the efficacy of adjuvant human papillomavirus (HPV) vaccination in patients treated for HPV-related disease across different susceptible organ sites. Methods: A systematic review was conducted to identify studies addressing the efficacy of adjuvant HPV vaccination on reducing the risk of recurrence of HPV-related preinvasive diseases. Results were reported as mean differences or pooled odds ratios (OR) with 95% confidence intervals (95% CI). Results: Sixteen studies were identified for the final analysis. Overall, 21,472 patients with cervical dysplasia were included: 4132 (19.2%) received the peri-operative HPV vaccine, while 17,340 (80.8%) underwent surgical treatment alone. The recurrences of CIN 1+ (OR 0.45, 95% CI 0.27 to 0.73; p = 0.001), CIN 2+ (OR 0.33, 95% CI 0.20 to 0.52; p < 0.0001), and CIN 3 (OR 0.28, 95% CI 0.13 to 0.59; p = 0.0009) were lower in the vaccinated than in unvaccinated group. Similarly, adjuvant vaccination reduced the risk of developing anal intraepithelial neoplasia (p = 0.005) and recurrent respiratory papillomatosis (p = 0.004). No differences in anogenital warts and vulvar intraepithelial neoplasia recurrence rate were observed comparing vaccinated and unvaccinated individuals. Conclusions: Adjuvant HPV vaccination is associated with a reduced risk of CIN recurrence, although there are limited data regarding its role in other HPV-related diseases. Further research is warranted to shed more light on the role of HPV vaccination as adjuvant therapy after primary treatment.

Adjuvant HPV Vaccination to Prevent Recurrent Cervical Dysplasia after Surgical Treatment: A Meta-Analysis.

Objective: The aim of this meta-analysis was to discuss evidence supporting the efficacy of adjuvant human papillomavirus (HPV) vaccination in reducing the risk of recurrent cervical intraepithelial neoplasia (CIN) 2 or greater after surgical treatment. Methods: A systematic literature search was performed for studies reporting the impact of HPV vaccination on reducing the risk of recurrence of CIN 2+ after surgical excision. Results were reported as mean differences or pooled odds ratios (OR) with 95% confidence intervals (95% CI). Results: Eleven studies met the inclusion criteria and were selected for analysis. In total, 21,310 patients were included: 4039 (19%) received peri-operational adjuvant HPV vaccination while 17,271 (81%) received surgery alone. The recurrence of CIN 2+ after treatment was significantly lower in the vaccinated compared with the unvaccinated group (OR 0.35; 95% CI 0.21–0.56; p < 0.0001). The recurrence of CIN 1+ after treatment was significantly lower in the vaccinated compared with the unvaccinated group (OR 0.51; 95% CI 0.31–0.83; p = 0.006). A non-significant trend of reduction rate of HPV persistence was observed in the vaccinated compared with the unvaccinated cohorts (OR was 0.84; 95% CI 0.61–1.15; p = 0.28). Conclusions: HPV vaccination, in adjuvant setting, is associated with a reduced risk of recurrent CIN 1+ and CIN 2+ after surgical treatment.

Surgical Treatment of Vulvar HSIL: Adjuvant HPV Vaccine Reduces Recurrent Disease

Data suggest that adjuvant human papillomavirus (HPV)-vaccination in women treated for cervical HPV diseases reduces recurrent disease. This study investigates adjuvant HPV-vaccination and the rate of recurrence in women undergoing surgery for vulvar high-grade squamous intraepithelial lesions (HSIL). From January 2013 to April 2020, we enrolled 149 women in a prospective case-control study. The control group (NV-group) was treated by standard surgery alone, while the study group received adjuvant vaccination soon after surgery (V-group). A follow-up was performed by vulvoscopy and HPV test. Statistical analysis was performed by Fisher’s exact test. HSIL recurrence was observed in 24/76 (32%) patients in NV-group and in 8/42 patients (19%) of the vaccinated group. By analysing the recurrence rate related to the incident and reactivated latent HPV infection, we found a significant difference between (17/76) 22.3% in NV-group and (2/42) 4.8% in V-group (p = 0.01). A reduction of 78.5% in incident/reactivated HPV infections was demonstrated. Data results add to the current knowledge about the mechanism of post-surgical adjuvant HPV vaccination. Our prospective study is the first to document the vaccine clinical effectiveness in preventing “reactivation” of latent HPV infections. Quadrivalent HPV vaccine administered after the surgical treatment for vulvar HSIL appears to be useful in preventing recurrent disease.

Serum Anti-HPV Antibody Titer as a Marker of Vaccine Effectiveness in Males with Genital Infection.

Introduction: Persistent human papillomavirus (HPV) semen infection is increasingly associated with male infertility. Adjuvant HPV vaccination is suggested to reduce the time to clearance and the disease relapse in males with persistent HPV semen infection. However, only a sub-population of patients show a clinical benefit from adjuvant vaccination. Here, we aimed to address the effectiveness rate of HPV adjuvant vaccination in males with genital tract infection and the possible prognostic markers of healing. Methods: Clinical records from 379 patients with persistent seminal HPV detection, all receiving HPV adjuvant vaccination, were considered. Clinical data, including genital HPV-DNA assessment by INNO-LiPA genotyping, semen HPV-DNA analysis by FISH analysis and serum antibody titer, were collected at basal (T0) and after 6 months (T1) since the vaccination cycle ended. Results: Clearance of genital HPV-DNA was recorded in 326 (86%) patients. Serum HPV-antibody titer at T1 was the most important prognostic factor associated with HPV-DNA clearance. A serum antibody titer equal to or greater than the threshold value 1:125, obtained by ROC curve analysis, was prognostic of healing. Conclusions: Anti-HPV antibody represents a suitable marker of adequate immune response to HPV vaccination in patients with genital infection.

Adjuvant Human Papillomavirus Vaccine to Reduce Recurrent Cervical Dysplasia in Unvaccinated Women: A Systematic Review and Meta-analysis.

To perform a systematic review and meta-analysis evaluating the efficacy of adjuvant human papillomavirus (HPV) vaccination in preventing recurrent cervical intraepithelial neoplasia (CIN) 2 or greater after surgical excision. Electronic databases (Cochrane, PubMed, EMBASE, MEDLINE, Scopus, and ClinicalTrials.gov) were searched for studies comparing surgical excision alone to surgical excision with adjuvant HPV vaccination for CIN 2 or greater. Studies published from January 1990 to January 2019 were included. A total of 5,901 studies were reviewed. The primary outcomes evaluated included: recurrence of CIN 2 or greater, CIN 1 or greater, and HPV 16,18 associated CIN within 6-48 months. We used Covidence software to assist with screening, and meta-analysis was performed using Review Manager. Six studies met inclusion criteria and were included in the final analysis. In total 2,984 women were included; 1,360 (45.6%) received adjuvant HPV vaccination after surgical excision, and 1,624 (54.4%) received either placebo or surgical management alone for CIN 2 or greater. Recurrence of CIN 2 or greater occurred within 6-48 months in 115 women (3.9%) overall; however, recurrence was significantly lower for vaccinated women: 26 of 1,360 women (1.9%) vs 89 of 1,624 unvaccinated women (5.9%) (relative risk [RR] 0.36 95% CI 0.23-0.55). The risk of CIN 1 or greater was also significantly lower with adjuvant HPV vaccination, occurring in 86 of 1,360 vaccinated women (6.3%) vs 157 of 1,624 unvaccinated women (9.7%) (RR 0.67 95% CI 0.52-0.85). Thirty-five women developed recurrent CIN 2 or greater lesions specific to HPV 16,18; nine received adjuvant vaccination (0.9%) vs 26 who were unvaccinated (2.0%) (RR 0.41 95% CI 0.20-0.85). Adjuvant HPV vaccination in the setting of surgical excision for CIN 2 or greater is associated with a reduced risk of recurrent cervical dysplasia overall and a reduction in the risk of recurrent lesions caused by the most oncogenic strains (HPV 16,18). Human papillomavirus vaccination should therefore be considered for adjuvant treatment in patients undergoing surgical excision for CIN 2 or greater. PROSPERO, CRD42019123786.

HPV vaccination as preventive approach for recurrent respiratory papillomatosis - a 22-year retrospective clinical analysis

BackgroundRecurrent respiratory papillomatosis (RRP) is a rare, benign disease of the aerodigestive tract, especially the larynx, caused by infection with the human papillomavirus (HPV) types 6 or 11. Current management focuses on surgical debulking with microdebrider of papillomatous lesions with or without concurrent adjuvant therapy, e.g. Cidofovir®. This retrospective study evaluates the results of patients treated at a department of the university clinic between 1990 and 2012 and compares the results of the conventional treatment with a new treatment approach using adjuvant vaccination with Gardasil®.MethodsA retrospective Kaplan Maier analysis of n = 24 patients diagnosed and treated with RPR was performed. The records were reviewed for gender, age at the time of first manifestation of disease and time to recurrence.ResultsOnly n = 2 (15.4%) of the n = 13 vaccinated patients developed a recurrence of the disease after a mean time of 54.9 months (SD: 9.5 months). All patients who were not vaccinated (n = 11; 100%) developed a relapse after a mean time of 12.3 months (SD: 9.72 months).ConclusionWe propose that adjuvant HPV vaccination with Gardasil® might have a preventive effect in RRP by occluding new papilloma formation.
