Cervical intraepithelial neoplasia in women infected with the human immunodeficiency virus: outcome after loop electrosurgical excision.

Our clinical experience with loop electrosurgical excision as therapy for cervical intraepithelial neoplasia (CIN) in women infected with human immunodeficiency virus is described. Information for this analysis was obtained from a retrospective chart review of all women with biopsy-confirmed CIN treated by loop electrosurgical excision who attended our colposcopy clinic during January 1991 to September 1992. Outcomes in women known to be HIV-seropositive were compared to those in women of unknown HIV serostatus. Patients included in the analysis were followed for at least 6 months or until the documentation of recurrent/persistent CIN, and all had at least one post-treatment colposcopic examination, including endocervical curettage and cervical biopsy of any acetowhite lesions. Recurrent/persistent CIN following loop excision was documented in 56% (19 of 34) HIV-infected women compared with 13% (10 of 80) women of unknown serostatus (OR 8.9, P < 0.001). HIV-infected women had a significantly higher rate of recurrent/persistent CIN than women of unknown serostatus, regardless of grade of CIN. In HIV-infected women, recurrent/persistent CIN following loop excision developed in 20% (1 of 5) with CD4+ T-lymphocyte counts > 500 cells/microliters compared to 61% (11 of 18) with CD4+ counts < or = 500 cells/microliters (P = 0.13). Loop electrosurgical excision has a high failure rate in HIV-infected women, and this failure rate may increase as the level of immunosuppression increases.
