Implications of Post-LLETZ “Treatment Failure” for Further Management of HIV-Infected Women

Abstract

Background. Since the preconisation presence of high-risk human papillomavirus (HR-HPV) is the main determinant of the risk of progression of preinvasive lesions; the state of the excision margins could be of less importance. Relatively little is known about the effect of human immunodeficiency virus (HIV) infection on the relation between the states of the excision margins. Methods. We compared 120 HIV-infected and 139 HIV-uninfected women who underwent a hysterectomy after large loop excision of the transformation zone (LLETZ) for abnormal Pap smear. Results. The excision margins had been reported negative in 21.7% of infected and 7.8% of uninfected cases ( = 0.03). Three (11.5%) of 26 negative margins in HIV-infected and 2 (18.2) out of HIV-uninfected cases were falsely negative as evidenced on hysterectomy specimens ( = 0.73). The persistence rate of the initial lesion was similar in both groups ( = 0.20). The persistence rate with highly active antiretroviral treatment (HAART) was similar to untreated patients ( = 0.20). The progression rate from low-grade to high-grade preinvasive lesions was higher in HIV-infected than HIVuninfected women ( = 0.027). Conclusion. HIV-infected women with incomplete excision margins after LLETZ are at higher risk of progression of residual preneoplastic lesions.
