Efficacy of visual inspection of the cervix using acetic acid in cervical cancer screening: a comparison with cervical cytology.
Screening programmes for the early detection of premalignant lesions of the cervix are expensive and technically difficult, especially in resource-challenged settings. There is a need for cheaper and equally effective alternative screening methods. This study compared the efficacy of visual inspection of the cervix using acetic acid (VIA) with the Pap smear method. A total of 186 subjects had a Pap smear followed by visual inspection of the cervix using 3 - 5% acetic acid with biopsies taken from suspicious acetowhite positive lesions. Cases of abnormal cytology were recalled for biopsies. A total of 150 subjects were negative for both tests; 30 (16.2%) were positive for VIA, while six were positive for both VIA and Pap smear. VIA detected one lesion missed by Pap smear on biopsy. The sensitivity of VIA was 100%, while that of Pap smear was 85.7%. The negative predictive value of VIA was 100%, while the positive predictive value was 20%. The sensitivity of VIA equals the reported rates for Pap smear. VIA is proposed as a credible alternative to Pap smear in resource-challenged settings.
