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

COVID pandemic consists one of the most challenging medical realities. Apart from affecting respiratory system, current evidence has demonstrated multiorgan manifestations that SARS-Cov-2 infection may actually have. However, one of the medical hypotheses not yet thoroughly tested is the impact on female reproductive system and more specifically cervix. No large observational studies have been performed to test presence of SARS-Cov-2 in cervical samples, while potential correlation and impact on HPV infection has not yet been examined. In this context, our research team has already planned to begin a prospective observational study regarding detection rates of SARS-CoV-2 genetic material in cervical cytology. The collected specimen will be analyzed for the presence of COVID-19 genetic material and in case of positive results, HPV typing will be performed as well in order to detect potential correlations between SARS-CoV-2 infection and HPV-infection. We would therefore like to launch our idea to control for SARS-CoV-2 infection in cervical specimen as well as examine potential correlation with HPV infection. Potential scientific proof of such hypothesis would change much regarding follow-up of HPV-positive patients while also triggering further research regarding aitiopathogenetic pathways of COVID. Communication of such a medical hypothesis could potentially motivate colleagues worldwide to expand their interest also on the research of SARS-CoV-2 cervical infection, in an effort to optimize our level of knowledge towards this new threatening and unknown reality of SARS-CoV-2.
