DIAGNOSTIC VALUE OF COLPOSCOPY IN PATIENTS WITH ABNORMAL PAP SMEAR

Abstract

 

Introduction: In order to reduce invasive cervical cancer, it is necessary to follow presisly the patients with abnormal pap smear. Simply, repeating the cytologic assessment in patints with atypical pap smear will result in missing 26-83 percent of squamous intraepithelial lesions and most alarming 50 percent of invasive cancers. Considering the contraversy of different study reports about the diagnostic value of colposcopy in confirming the abnormal papsmear, this study was conducted to determine the sensitivity and specificity of colposcopy based on the results of biopsy in women referred to hospitals of Isfahan University of Medical Sciences (IUMS).
Methods: In a prospective study, we selected randomly 210 women from 700 patints who reffered to the hospitals of IUMS. These women were examined and biopsied simultaneously. The data was collected by a structured interview according to the demographic characteristics and then was analyzed using EPI software.
Results. From 210 subjects, only 125 were reported to have abnormal cervical cytologic. The sensitivity came out to be 97.29 percent and specificity was 43.20 percent.
Discussion. In Iran, according to the sensitivity and specificity for colposcpic examination, it can be suggested that in final evaluation of abnormal papsmears, colposcopic assesment of the cervix can be considered as the next appropriate step.
