To evaluate the recurrence rates of cervical intraepithelial neoplasia (CIN) in a cohort of HIV-infected and noninfected women who underwent the loop electrosurgical excision procedure (LEEP).
A prospective cohort study of 94 HIV-positive and 107 HIV-negative women, both with CIN, treated with LEEP. The diagnosis of recurrence was established after biopsy. The Kaplan-Meier method was used for survival analysis and multivariate analyses were carried out using the Cox proportional hazards regression model.
There was a predominance of low-grade lesions in HIV-positive compared with HIV-negative women (P<0.01). Recurrence was more frequent with compromised margins and glandular involvement (P<0.01). A multivariate analysis showed that HIV-infection, glandular involvement, and positive margins were independently associated with recurrence of lesions.
Recurrence rate of CIN in HIV-positive women was higher than in HIV-negative women. The factors associated with recurrence were HIV infection, glandular involvement, and positive margins.
评估接受环形电切术（LEEP）的感染人类免疫缺陷病毒（HIV）和未感染HIV的女性队列中宫颈上皮内瘤变（CIN）的复发率。
对94例HIV阳性和107例HIV阴性且均患有CIN的女性进行前瞻性队列研究，她们均接受了LEEP治疗。活检后确定复发诊断。采用Kaplan-Meier法进行生存分析，并使用Cox比例风险回归模型进行多变量分析。
与HIV阴性女性相比，HIV阳性女性中低级别病变占主导（P<0.01）。切缘受累和腺体受累时复发更频繁（P<0.01）。多变量分析显示，HIV感染、腺体受累和切缘阳性与病变复发独立相关。
HIV阳性女性中CIN的复发率高于HIV阴性女性。与复发相关的因素为HIV感染、腺体受累和切缘阳性。
