Effect of Surgical Therapy on the Courses of Human Papillomavirus Infection in Cervical Intraepithelial Neoplasia / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: To investigate whether human papillomavirus (HPV) associated with cervical intraepithelial neoplasia was successfully eliminated after surgical therapy such as large loop excision of transformation zone (LLETZ) or type I extended hysterectomy. METHODS: Seventy four cervical intraepithelial neoplasia (CIN) patients with HPV infection who were admitted for LLETZ or type I extended hysterectomy were recruited into this prospective study. HPV infection was confirmed by HPV DNA genotyping using HPV DNA Chip (Biomedlab, Seoul, Korea) before and after surgical therapy. RESULTS: According to the assay used (HPV DNA Chip(R)) at the postoperative visit, 82.5% of treated patients were completely free from HPV infection. And there was no statistical difference between LLETZ and type I extended hysterectomy (p=0.452). However, there was persistent infection in 17.5% of treated patients after final surgical therapy. CONCLUSION: Although the HPV infection associated with CIN was effectively eliminated after LLETZ and type I extended hysterectomy, there was persistent infection in 17.5% of treated patients. Therefore, the careful followed-up examination of HPV infection should be taken in these patients.
