Abstract

Context: The accuracy of colposcopy has recently been called into question particularly with regard to determining the site requiring biopsy. The technique of colposcopy is largely operator dependent, and the agreement between colposcopists is less reliable than once presumed. In an attempt to standardize colposcopy a new scoring system, the Swede score has been devised, which includes lesion size as a variable to be scored in addition to the 4 variables found in the modified Reids Colposcopic Index (RCI).

Aim: To assess the diagnostic accuracy of Swede score for pre-invasive cervical lesion.

Setting And Design: A cross-sectional study in a tertiary care centre.

Method: Swede score was calculated for assessment of pre-invasive cervical lesions on patients undergoing colposcopy who were suspected with pre-invasive cervical lesion. Cervical biopsy was taken if modified RCI ≥ 3 or Swede score ≥ 5. Histopathology report of the cervical biopsy was taken as gold standard.

Results: Swede scores of 5 or more had sensitivity, specificity, positive and negative predictive values of 94.9%, 88.4%, 75.5% and 92.9% respectively.

Conclusion: The Swede score by just incorporating one additional variable that is size of the lesion, showed better correlation with histopathology.
