title: Acceptable predictive accuracy of histopathology results by colposcopy done by Gynecology residents using Reid index.
abstract: OBJECTIVE
  The aim of this study was to determine the strength of the correlation between colposcopic impression according to Reid colposcopic index (RCI) done by Gynecology residents and biopsy histology in a university hospital.
  
  
  METHODS
  Colposcopy was performed on 260 women. According to RCI, the scores zero, one, or two were given to each of four standardized colposcopy patterns (acid staining, iodide staining, margin of lesion, and vascular pattern) and the total score was calculated. In those with multiple lesions, the patterns with the highest score were considered. Then the biopsy was obtained from the lesion and put in formalin for pathological evaluation.
  
  
  RESULTS
  There was a statistically significant association between colposcopy findings and histopathology findings and the score was increased as parallel as malignancy grade (r = 0.680, P < 0.05). The highest sensitivity and specificity for diagnosis of each CIN also were related to staining with acetic acid. For high-grade CIN lesions, the highest specificity was related to staining with acetic acid, but the sensitivity was equal for four findings.
  
  
  CONCLUSIONS
  Colposcopy using RCI yields a good correlation with histology results. It also showed that colposcopy done by Gynecology residents using RCI is a feasible and acceptable cervical cancer screening method in a university hospital.
