Abstract： Objective To explore the detection trend of vaginal intraepithelial neoplasia(VaIN)of lower genital tract from 2013 to 2015. Methods A retrospective analysis was undertaken of colposcopy-directed biopsy of cervical, vaginal and vulvar intraepithelial neoplasia lesions include cervical intraepithelial neoplasia (CIN), VaIN and vulvar intraepithelial neoplasia (VIN) in Obstetrics and Gynecology Hospital of Fudan University from January 2013 to December 2015. Results (1) Overall data of CIN, VaIN and VIN:a total of 16732 cases were diagnosed of lower genital intraepithelial neoplasia in 3 years, accounting for 23.20% (16732/72128) of total colposcopy-directed biopsy cases. Among them, CIN, VaIN and VIN accounted for 19.48%(14053/72128), 2.67%(1923/72128), 1.05%(756/72128) of total colposcopy-directed biopsy cases of the lower genital tract, 83.99%(14053/16732), 11.49%(1923/16732), 4.52%(756/16732) of total lower genital intraepithelial neoplasia, respectively. (2) Annual data of CIN, VaIN and VIN from 2013 to 2015. The annual proportion of CIN in all intraepithelial neoplasia of lower gential tract was basically stable, consisting of 86.02%(3955/4598),83.25%(4795/5760) and 83.20%(5303/6374), respectively. The annual proportion of VaIN was gradually increasing, consisting of 8.09% (372/4598), 12.45%(717/5760) and 13.08%(834/6374), respectively. The annual proportion of VIN was gradually decreasing, consisting of 5.89% (271/4598), 4.31% (248/5760) and 3.72% (237/6374), respectively. Conclusion The increasing detection of VaIN from 2013 to 2015 might correlate with the increasing attention to inspection of the entire vaginal wall.
