Evaluation of Downstaging, Visual Inspection with Acetic Acid and Lugol’s Iodine in Screening of Cervical Cancer

چکیده
Objectives: To detect and compare the sensitivity and specificity of downstaging and visual inspection with acetic acid (VIA) and with Lugol’s iodine (VILI). Methods: Screening with downstaging, VIA and VILI were done on 680 women who fulfilled the inclusion criteria at a primary health center attached to the university hospital, over a period of one year. Those who had abnormal results in downstaging, VIA and VILI were biopsied and sensitivity, specificity, negative predictive value and positive predictive value were calculated. Results: The sensitivities of downstaging, VIA and VILI were 54.55, 63.64 and 90.91% and specificities were 93.42, 95.07 and 97.46% respectively. The positive predictive value of downstaging, VIA and VILI were 12.01, 17.5 and 35.7% and negative predictive values were 99.2, 99.37 and 98.85% respectively. Conclusion: VIA and VILI are suitable primary screening procedures as compared to downstaging because of high sensitivity and specificity. The negative predictive value of downstaging, VIA and VILI is better than the positive predictive value. Downstaging can be used in rural areas where acetic acid and Lugol’s iodine are not available.

A Randomized Trial Comparing the Diagnostic Accuracy of Visual Inspection with Acetic Acid to Visual Inspection with Lugol’s Iodine for Cervical Cancer Screening in HIV-Infected Women
Visual inspection with Acetic Acid (VIA) and Visual Inspection with Lugol’s Iodine (VILI) are increasingly recommended in various cervical cancer screening protocols in low-resource settings. Although VIA is more widely used, VILI has been advocated as an easier and more specific screening test. VILI has not been well-validated as a stand-alone screening test, compared to VIA or validated for u...
