Risk factors for cervical intraepithelial lesions after loop electrosurgical excision procedure in HIV-infected and non-infected women - Revista Brasileira de Ginecologia e Obstetrícia

PURPOSE: to evaluate risk factors associated with cervical intraepithelial lesion recurrence after LEEP conization. METHODS: nested case-control study in a cohort of 201 patients with cervical intraepithelial lesion, that were submitted to LEEP conization. Average follow-up of these patients was 2 years. Ninety-four HIV-infected women and 107 non-infected were enrolled. Cervical conization was achieved by the Loop Electrosurgical Excision Procedure (LEEP). Evaluated surgical biopsy histopathological characteristics were lesion grade, lesion borders and glandular involvement. After surgery all patients were submitted to a colposcopy and cytological evaluation every six months. Recurrent lesions were defined it confirmed by biopsy after surgery. Cases were patients with and controls patients without recurrence. chi2 test and multivariable analysis by logistic regression were used for group comparisons. Kaplan Meier’s method was performed for the survival analyses (log-rank test). RESULTS: 40 patients had lesion recurrence. Initially, significant variables were: partner number, HIV-infection, lesion borders and glandular involvement. The most frequent recurrence occurred when there were simultaneous association between positive margins and glandular involvement as indicator for recurrence risk. After logistic regression analysis the main factors associated with lesion recurrence were: glandular involvement (OR-9.1; 95% CI:13.0- 27.5); HIV-infection (OR-4.6; 95% IC:1.1-6.3); compromised margins (OR-2.6; 95% IC:1.9-11.2). CONCLUSIONS: risk factors associated with cervical intraepitelial lesion recurrence were HIV-infection, glandular involvement and compromised margins.
