Background: Cervical cancer is one of the leading causes of death among women facing gynecological problems. It requires early detection by various screening methods.
Aims and Objectives: The current research aimed to assess the diagnostic utility of pap smear cytology and visual inspection of acetic acid (VIA) as a screening test for various cervical lesions.
Materials and Methods: The current prospective study was conducted on 210 non-pregnant women. Cervical pap smears were taken and reported according to the revised Bethesda system, 2014. VIA examination was also done, and any dense opaque aceto-white lesion observation near the squamo-columnar junction was reported as VIA positive. The findings of pap smear cytology and VIA were correlated with findings of histopathology.
Results: Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of pap smear cytology for the diagnosis of cervical lesions were found to be 90.16%, 85.22%, 89.43%, 86.2%, and 88.09%, respectively; while sensitivity, specificity, PPV, NPV, and diagnostic accuracy of VIA for the diagnosis of cervical lesions were found to be 88.37%, 55.55%, 76%, 75%, and 75.71%, respectively. Our study showed a substantial degree of agreement between pap smear cytology and histopathology for the diagnosis of cervical lesions with Cohen’s kappa value being 0.755.
Conclusion: The current study revealed that pap smear and VIA have high sensitivity with good diagnostic accuracy for the detection of neoplastic cervical lesions, which indicate that they can be used as an efficient screening tool for the detection of cervical lesions in their earlier stages.
