Significance of human papillomavirus genotyping with high-grade cervical intraepithelial neoplasia treated by a loop electrosurgical excision procedure.

Abstract

This study was conducted to determine whether the human papillomavirus (HPV) genotype by the HPV DNA chip test (HDC) is predictive of residual or recurrent high-grade cervical intraepithelial neoplasia (CIN) 2-3 following a loop electrosurgical excision procedure (LEEP). Between January 2001-February 2007, 672 patients with CIN2-3 were treated by a LEEP and followed up with cytology, the hybrid capture II assay, and the HDC. A total of 37 (5.5%) patients developed a recurrence, and those who developed a recurrence tested positive for the same high-risk (HR) HPV genotype before and after the LEEP. The same HR-HPV genotype by the HDC during the follow-up had a sensitivity and negative predictive value of 100% for detecting residual/recurrent disease. Persistent HPV-16 and HPV-18 were significantly associated with recurrent CIN2-3 (P < .05). Persistent infection with the same HR-HPV genotype, especially HPV-16 and HPV-18, should be considered a risk factor for developing residual/recurrent CIN2-3.
