Objective
This study aimed to investigate the characteristics and screening history of vaginal intraepithelial neoplasia (VaIN) or vaginal cancer and compare the sensitivity of cytology and human papillomavirus (HPV) tests on the cervix against vaginal and cervical high-grade squamous intraepithelial lesion or cancer.
Methods
This study included patients who underwent colposcopy-directed biopsy and were diagnosed with VaIN or vaginal cancer from February 2013 to November 2022. Clinical information was obtained from the medical records of the department. Statistical analysis was performed on SPSS 26.0 (IBM Corp, Armonk, NY) using
Results
A total of 1,166 patients were included in this study. The median age of VaIN2+ patients was 50.5 years, whereas VaIN1 reported a median age of 42.1 years old,
Conclusions
Human papillomavirus 16 is the dominant HPV type in vaginal precancer lesions. Cervical cancer screening has similar sensitivity for VaIN2+ as for cervical intraepithelial neoplasia 2+, with hr-HPV testing showing higher sensitivity than cytology.
