Comparison of Diagnostic Accuracy of Colposcopic Findings Using Modified Reid Colposcopic Index with Histopathology in Cervical Lesions

Abstract

Background: Colposcopy is a screening procedure used to detect pre invasive stages of carcinoma cervix. The accuracy of colposcopy is varied among colposcopists. To control the quality of colposcopy, Reid colposcopic index (RCI) was originated. However, the colposcopic features in RCI were subjective for some features. Objective: The aim of the study was to compare the diagnostic accuracy of colposcopic findings using modified Reid Colposcopic Index with histopathology in cervical lesions. Material and Methods: This was a prospective comparative study. A total number of 50 women who met the selection criteria were included in the study. Colposcopy was performed and results were evaluated using Reid colposcopic index. Colposcopic guided biopsy was taken in cases with abnormal colposcopic findings and finally the results of colposcopy and histopathology were compared. Results: According to Reid colposcopic index, there were 54% benign cases, 18% women were diagnosed as CIN 1, 16 % CIN 2 and 12% as CIN 3 where as on histopathological correlation 58% were benign, where as 12%, 16%, 14% were diagnosed as CIN 1, CIN 2, CIN 3 respectively. The general accuracy rate was 92% and specificity of colposcopic examination was 90.48%. The kappa value was 0.903(p=0.000.05). Conclusion: This study demonstrated high accuracy and correlation between colposcopy and histopathology.
