ABSTRACT

OBJECTIVE: 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. DATA SOURCES: 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. METHODS: 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. TABULATION, INTEGRATION, AND RESULTS: 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). CONCLUSION: 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.

ABSTRACT

OBJECTIVES: to assess the completeness and timeliness of Human papillomavirus (HPV) vaccination programme in Friuli Venezia Giulia (FVG) Region (Northern Italy), notably by monitoring 2-dose coverage among girls before they turn 15 years old (referred to as "at 15") in each year between 2009 and 2018 and making a preliminary evaluation of coverage among boys at 13 years in 2016-2018. DESIGN: retrospective study. SETTING AND PARTICIPANTS: for each vaccine recipient, demographic information and history of HPV vaccine uptake from the digital FVG Vaccination Registry updated as of 31.12.2018 were extracted. Numerator data comprised all doses allocated to FVG residents. Age-specific denominators were derived from the FVG census in each examined year. Coverage estimates for the year 2018 were also provided by number of doses. MAIN OUTCOME MEASURES: coverage for a full course of HPV vaccine, defined as 2 doses in girls and boys younger than age 15 years but 3 doses in less young women. RESULTS: In FVG 52,217 females had received >=1 dose since 2008 and 12,152 males since 2015. >=2-dose coverage in girls at 15 increased from 42% in 2009 to 76% in 2015 and slightly declined afterwards (69% in 2018). In 2008, 3-dose coverage was 65%, 74%, and 59% in females aged 16-17, 18-19, and 20-26 years, respectively. In the same year, 2-dose coverage in boys at 13 years was 54%, similar to the coverage in girls at 13 years (57%). CONCLUSIONS: this paper shows the achievements of routine and catch-up HPV vaccination in FVG. While coverage in girls at 15 years of age peaked in 2015 and slightly diminished in subsequent years, the coverage in boys at 13 in 2018 had already approached the coverage in same-age girls (57%). On account of the signs of weakening in girls' coverage, campaigns in support to HPV vaccination must be repeated, especially in favour of the most cost-effective group, i.e., girls before 15 years of age. The heavy burden posed by the COVID-19 emergency on other prevention-related activities makes a better targeted use of HPV vaccination even more necessary.

ABSTRACT

The Coronavirus Disease 2019 (COVID-19) pandemic has been growing, including in Japan where it has been estimated that as many as 3.1% of patients positive for new CoV strain SARS-CoV-2 might die of COVID-19-related respiratory failure. Meanwhile, human papillomavirus (HPV) is spreading in Japan. The fatality rate for HPV-associated cancers after infection with HPV is as much as that for COVID-19 in Japan, although the time to disease is much longer for HPV. Among advanced countries, the cervical cancer screening rate in Japanese females is very low. The Japanese Ministry of Health, Labor and Welfare (MHLW) suspended its official recommendation for HPV vaccination in June 2013 due to alleged adverse post-vaccination events in several young girls, such as chronic pain and motor impairment, which were repeatedly reported in the media. Subsequently, the rate for vaccinating girls plummeted from approximately 70% to the current rate of 1% or less. Women should accept HPV vaccination for the eventual prevention of cervical cancer with the same passion they are for COVID-19 testing.
