Abstract Objective This study aimed to examine the associations of cone margin and human papillomavirus (HPV) status after conization with cytological abnormalities and disease recurrence in patients with cervical intraepithelial neoplasia grade 3 (CIN3). Methods This is a retrospective study of 366 women with CIN3 who underwent conization at Kagoshima University Hospital between 2004 and 2017. Conization was performed using an ultrasonic scalpel. The polymerase chain reaction for detecting HPV genotypes was performed using fresh cervical cell samples. We examined the associations of margin status and HPV status after conization with cytological abnormalities and recurrence. Results Among 224 women with CIN3, 193 (86.2%) underwent HPV genotype testing before conization. The HPV-positive rate was 84.9%. The most common HPV genotypes before conization were HPV 16, 31, 58, 52, 18, 35, and 33. In 191 patients, the uterus was preserved after conization. Sixteen patients had pathologically positive margins, 165 had negative margins, and 10 had unclear margins. There was no significant difference in abnormal cytology and recurrence rate after conization between the three groups. Five patients with positive margins and abnormal cytology during follow-ups were HPV16- or HPV58-positive in the preoperative HPV testing. Of the 191 women, 91 (47.6%) underwent pre- and postoperative HPV genotype testing, among whom 14 (15.4%) were HPV-positive after conization. No significant difference in abnormal cytology based on HPV status after conization was found. The recurrence rate tended to be higher in HPV-positive patients than in HPV-negative patients after conization (21.4% vs. 1.3%, p
