PAP Test Versus Colposcopy for Cervical Cancer Screening in HIV-Seropositive Women: A Case-Control Study

PurposeThe prevalence of pre-invasive lesions (PIL) of cervix in human immunodeficiency virus (HIV)-seropositive women ranges from 12.5 to 69%. Although Papanicolaou (PAP) test is the recommended screening method, it has concerns owing to high false-negative cytology in HIV-infected women and is associated with high attrition rates. The current study aims to compare the role of routine colposcopy with PAP test at initial visit for screening of pre-invasive lesions of cervix in HIV-seropositive women.MethodsA cross-sectional study of 120 HIV-seropositive women aged 25-50 years and screened for PIL of cervix by PAP test and colposcopy simultaneously was conducted. Colposcopy-directed biopsy was taken if SWEDE score was >= 5, and the results were compared with PAP report as well as the histopathology findings.ResultsOut of the 120 women screened, abnormal colposcopy was found in 22 women (18.3%) out of which 12 (54.54%) were positive for PIL of cervix on biopsy as well. Abnormal PAP test was found in 6 women (5%), and all had abnormal colposcopy and histopathological findings suggestive of PIL as well. There were 6 women with PIL of cervix who would have been missed if only PAP test was to be used as the screening modality.ConclusionColposcopy was superior in detection of PIL of cervix in HIV-seropositive women. Therefore, the authors conclude that colposcopy should be incorporated as a primary screening tool for pre-invasive lesions of cervix in HIV-seropositive women.
