| Summary: | Abstract Objective The purpose of this study was to identify the clinical characteristics of patients with high-grade squamous intraepithelial lesions (HSIL) with abnormal endocervical curettage (ECC) and to evaluate the efficacy of abnormal preoperative ECC in predicting recurrence after a loop electrosurgical excision procedure (LEEP). Methods We retrospectively analyzed a total of 210 cases of histological HSIL in female patients diagnosed using cervical biopsy and/or indiscriminating ECC, and these included 137 cases with normal ECC and 63 cases with abnormal ECC. We also collected preoperative information and data on postoperative human papillomavirus (HPV) and histological outcomes within 2 years. Results The additional detection rate of HSIL using indiscriminating ECC was 5%. Patients with abnormal ECC were older (P < 0.001), predominantly menopausal (P = 0.001), had high-grade cytology (P = 0.032), a type 3 transformation zone (P = 0.046), and a higher proportion of HPV type 16/18 infection (P = 0.023). Moreover, age (odds ratio [OR] = 1.078, 95% confidence interval [CI] = 1.0325–1.1333, P = 0.003) and HPV 16/18 infection (OR = 2.082, 95% CI = 1.042–4.2163, P = 0.038) were independent risk factors for abnormal ECC. With an observed residual lesion/recurrence rate of 9.5% over the 24-month follow-up, we noted a 9.3% higher rate in the abnormal ECC group when compared with the normal ECC group. Abnormal preoperative ECC (OR = 4.06, 95% CI = 1.09–15.14, P = 0.037) and positive HPV at the 12-month follow-up (OR = 16.55, 95% CI = 3.54–77.37, P = 0.000) were independent risk factors for residual disease/recurrence. Conclusion Preoperative ECC was one of the risk factors for post-LEEP residual/recurrent HSIL, and detecting abnormal ECC when managing older patients or patients with HPV 16/18 infection during colposcopy is critical.
