Background/Objective: Women treated with large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia grade 2-3 (CIN2-3) remain at risk of CIN2-3 and cervical cancer for many years. We assessed the roles of high-risk human papillomavirus (HR-HPV) post-LLETZ, surgical margins, and LLETZ characteristics on the long-term risk of CIN2-3. Methods: A retrospective observational study was performed using data for 432 women with a histological diagnosis of CIN2-3 treated by LLETZ between 1996 and 2020 and followed-up until October 2021 at Hospital Bellvitge in Barcelona, Spain. Age, surgical margins, 6-month HR-HPV status, excision type, and cone volume/dimensions were analyzed in association with the risk of persistent/recurrent CIN2-3. The cumulative probability of persistent/recurrent CIN2-3 was calculated using the Kaplan–Meier and Cox models. Results: Persistent/recurrent CIN2-3 was detected in 7.4%, with over 90% found within 5 years post-LLETZ. Predictors of persistent/recurrent CIN2-3 were HR-HPV (HR = 7.36, 95% CI = 3.55–15.26), involved margins (HR = 3.94, 95% CI = 1.68–9.25), uncertain margins (HR = 4.42, 95% CI = 1.55–12.55), and age ≥ 35 years (HR = 2.92, 95% CI = 1.19–7.13). Type 3 excision (p= 0.035) and cone length (p= 0.010) correlated with clear margins. The negative predictive value (NPV) of both negative HR-HPV and clear margins post-LLETZ was 98.7%. Conclusions: The combination of negative HR-HPV and clear margins post-LLETZ provides stronger reassurance against the risk of persistent/recurrent CIN2-3 than do LLETZ characteristics. However, larger excisions in older women likely reduce the risk of involved margins. Close surveillance, including repeat HR-HPV testing in the first 5 years post-LLETZ, is crucial.
背景/目的:接受宫颈转化区大环切除术(LLETZ)治疗的宫颈上皮内瘤变2-3级(CIN2-3)患者,在术后多年内仍面临CIN2-3及宫颈癌的风险。本研究评估了LLETZ术后高危型人乳头瘤病毒(HR-HPV)状态、手术切缘及LLETZ特征对CIN2-3长期复发风险的影响。方法:本研究为回顾性观察性研究,纳入1996年至2020年间在西班牙巴塞罗那贝尔维特医院经组织学诊断为CIN2-3并接受LLETZ治疗的432例女性患者,随访至2021年10月。分析年龄、手术切缘状态、术后6个月HR-HPV状态、切除类型及锥切体积/尺寸与CIN2-3持续/复发风险的关系。采用Kaplan-Meier法和Cox模型计算CIN2-3持续/复发的累积概率。结果:CIN2-3持续/复发率为7.4%,其中超过90%发生在LLETZ术后5年内。CIN2-3持续/复发的预测因素包括:HR-HPV阳性(HR=7.36,95% CI=3.55–15.26)、切缘阳性(HR=3.94,95% CI=1.68–9.25)、切缘不确定(HR=4.42,95% CI=1.55–12.55)以及年龄≥35岁(HR=2.92,95% CI=1.19–7.13)。3型切除(p=0.035)和锥切长度(p=0.010)与切缘阴性相关。LLETZ术后HR-HPV阴性且切缘阴性的阴性预测值(NPV)为98.7%。结论:与LLETZ手术特征相比,术后HR-HPV阴性联合切缘阴性对降低CIN2-3持续/复发风险具有更强的保障作用。然而,对高龄女性实施更大范围的切除可能降低切缘阳性的风险。密切随访(包括在LLETZ术后5年内重复HR-HPV检测)至关重要。
