In postmenopausal women with high-grade cervical intraepithelial neoplasia (CIN3), hysterectomy is frequently performed after loop electrosurgical excision procedure (LEEP) due to the concern for residual disease or occult carcinoma. However, the decision to proceed with hysterectomy is often made without validated predictive criteria, increasing the risk of overtreatment or underdiagnosis. The aim of this study is to identify independent predictors of residual CIN2+ (CIN2, CIN3, adenocarcinoma in situ, invasive carcinoma) or invasive disease in hysterectomy specimens following LEEP in this high-risk population. Methods: We conducted a multicenter retrospective study including 154 postmenopausal women (aged 50–75) who underwent total hysterectomy within 12 months after LEEP for histologically confirmed CIN3. Data collected included human papillomavirus (HPV) genotyping (pre- and post-LEEP), endocervical curettage (ECC), cone margin status, transformation zone type, and histopathological outcomes of the hysterectomy specimen. Logistic regression and ROC curve analysis were used to assess predictive factors. Results: Residual disease (CIN2+, AIS, or carcinoma) was found in 38 patients (24.7%), including 7 cases (4.5%) of occult carcinoma. Persistent high-risk HPV post-LEEP was the strongest independent predictor (adjusted OR for HPV 16/18: 74.0;p< 0.001), followed by positive ECC (OR: 3.64;p= 0.028). Cone margin status was not independently associated. The multivariate model showed good discriminative performance (AUC = 0.860; sensitivity 67.2%, specificity 72.8%). Conclusions: Our findings suggest that persistent high-risk HPV infection and positive ECC are reliable predictors of residual or occult disease. These markers should be integrated into post-LEEP follow-up protocols to better identify candidates for hysterectomy and minimize unnecessary surgeries.
在患有高级别宫颈上皮内瘤变（CIN3）的绝经后女性中，由于担心存在残留病变或隐匿性癌，环形电切术（LEEP）后常进行子宫切除术。然而，决定是否进行子宫切除术往往缺乏经过验证的预测标准，从而增加了过度治疗或诊断不足的风险。本研究旨在确定这一高危人群中，LEEP术后子宫切除标本中残留CIN2+（CIN2、CIN3、原位腺癌、浸润性癌）或浸润性疾病的独立预测因素。方法：我们进行了一项多中心回顾性研究，纳入了154名绝经后女性（年龄50-75岁），她们在因组织学确诊为CIN3而接受LEEP后的12个月内接受了全子宫切除术。收集的数据包括人乳头瘤病毒（HPV）基因分型（LEEP术前及术后）、宫颈管搔刮术（ECC）结果、锥切缘状态、转化区类型以及子宫切除标本的组织病理学结果。采用逻辑回归和ROC曲线分析评估预测因素。结果：38例患者（24.7%）发现残留病变（CIN2+、原位腺癌或癌），其中包括7例（4.5%）隐匿性癌。LEEP术后持续存在的高危HPV感染是最强的独立预测因素（HPV 16/18的调整后OR值为74.0；p < 0.001），其次是阳性ECC结果（OR：3.64；p = 0.028）。锥切缘状态无独立相关性。多变量模型显示出良好的区分性能（AUC = 0.860；敏感性67.2%，特异性72.8%）。结论：我们的研究结果表明，持续的高危HPV感染和阳性ECC结果是残留或隐匿性疾病的可靠预测指标。这些标志物应纳入LEEP术后随访方案，以更好地识别适合进行子宫切除术的患者，并最大限度地减少不必要的手术。
