Abstract
OBJECTIVE:
To assess the prevalence of high-risk human papillomavirus (hrHPV) and human papillomavirus (HPV)–associated abnormalities in the neovaginas of postvaginoplasty transfeminine patients to inform potential HPV-screening guidelines for this patient population.
DATA SOURCES:
MEDLINE, ClinicalTrials.gov, the Cochrane Library, Scopus, and Google Scholar were searched through September 30, 2022.
METHODS OF STUDY SELECTION:
The population included transfeminine individuals who had undergone vaginoplasty with an outcome of subsequent positive HPV diagnosis or HPV-related lesions. Randomized clinical trials, cohort studies, cross-sectional studies, and case reports available in English were included in the analysis. Identified articles were doubly screened, and accepted articles were doubly extracted.
TABULATION, INTEGRATION, AND RESULTS:
Of 59 abstracts identified, 30 were screened for eligibility, of which 15 met the criteria for review. Included studies were assessed for vaginoplasty procedure type, time elapsed between vaginoplasty and HPV testing, HPV type, location and manner of sample collection, method of HPV diagnosis, and classification and location of HPV-associated neovaginal lesions. Studies were assigned a grade of evidence of very low, low, moderate, or high based on study design, precision, directness, and risk of bias. Prevalence of neovaginal hrHPV ranged from 8.3% to 20% in identified studies, and per-study prevalence of HPV-related neovaginal abnormalities ranged from 0% to 8.3% in patients.
CONCLUSION:
The current body of research demonstrates that, after vaginoplasty, transfeminine individuals may develop neovaginal HPV infection with associated cytologic abnormalities or grossly apparent lesions. In some included studies, neovaginal HPV-associated lesions were highly advanced before they were identified. A small number of studies assessed neovaginal HPV prevalence in transfeminine individuals, with hrHPV prevalence ranging from 8.3% to 20%. However, broader conclusions about neovaginal HPV prevalence are limited by a lack of high-grade evidence in the existing literature. More rigorous prevalence research is needed to inform preventative care guidelines for transfeminine individuals at risk of developing HPV-related neovaginal complications.
