The results of cytology, hrHPV, colposcopic examination and history of hysterectomy were retrospectively analysed.Results: A total of 26,432 colposcopies were performed during the study period, among which 2131 women (1835 [86.1%] with VaIN 1; 268 [12.6%] with VaIN 2/3; and 28 [1.3%] with vaginal cancer) were retrospectively studied. hrHPV test positivity was significantly higher than that of cytology for VaIN 1 (84.4% vs 67.3%; P < 0.001) and VaIN 2/3 (92.0% vs 79.9%; P < 0.001) but not for vaginal cancer (84.6% vs 78.6%; P = 0.73). Additionally, the concordance rates for colposcopic impression were 79.5%, 54.5%, and 92.8% for VaIN1, VaIN2/3, and vaginal cancer, respectively. All 372 patients had a history of hysterectomy, and 81.0% (282/348) of indications were related to cervical precancer and cancer. Although cytology test positivity was significantly higher in patients with hysterectomy than in patients without hysterectomy (76.2% vs 67.5%; P < 0.001), cytology combined with hrHPV can help to detect more than 95% of VaIN and vaginal cancer cases in both groups (96.2% for patients with hysterectomy and 96.5% for patients without hysterectomy).Conclusion: VaIN and vaginal cancer are not rare diseases. Although cytology was sensitive (67.5%– 76.2%) for detecting vaginal lesions regardless of hysterectomy, cytology combined with hrHPV improves detection accuracy up to 95% in both groups.Keywords: cytology, human papilloma virus, colposcopy, vaginal intraepithelial neoplasia, vaginal cancer |
