Abstract: Background Ca cervix is the most common cancer among women in developing countries.In developed countries, screening is done by Pap smear which is resulting in drastic decrease in ca cervix which is not so in developing countries due to various reasons.So visual inspection of cervix can be cost effective screening procedure if its efficacy is proved in low resource countries.OBJECTIVE: To determine which screening method is efficient in detecting premalignant & malignant lesions of ca cervix in resource poor settings.METHODS: Pap smear was done in all 600 women, along with this VIA in 200 women, VILI in 200 women was done.Either pap or VIA or VILI positive cases were selected for colposcopy followed by biopsy if positive findings were there on colposcopy.10% of either screening negative cases were subjected for biopsy to know false negative rate from each group.Main outcome measures: comparison of all three screening methods (pap smear, VIA, VILI) in terms of sensitivity, specificity, PPV, NPV in comparison with gold standard colposcopic guided cervical biopsy.RESULTS: The aided visual inspection has more PPV than pap smear, The sensitivity of all three screening methods were comparable.The specificity & NPV of pap smear were high.CONCLUSION: So the aided visual inspection can be used as screening method in detection of premalignant and malignant lesions of cervix in place of papsmear especially in rural setting.
