The Incidence of Vaginal Intraepithelial Neoplasia 2+ in Patients With Previous Hysterectomy Cervival Intraepithelial Neoplasia 3+ Between 2005–2015: A Population-Based Study

Individuals with evidence of CIN3+/AIS at time of hysterectomy are at elevated risk of developing VAIN 2+, with the highest risk occurring within 5 years from surgery. Vault cytology within 1 year of surgery will identify most cases of VAIN2+, but further data monitoring and integration of HPV testing will be required to determine this screening strategy.
