A comparative study between Reid’s colposcopic index score and Swede score in women suspected of cervical cancer

Abstract

Objectives: This prospective study was conducted to compare the two widely used colposcopic indices: Reid Colposcopic Index (RCI) score and Swede score. Materials and Methods: This study was conducted on 567 women aged more than 21 years who had a positive screening test or were having symptoms of postcoital / postmenopausal bleeding or unhealthy looking cervix. Colposcopic examination was done in all such patients. RCI score and Swede score were calculated from the colposcopic findings. Biopsy was taken and HPE results were recorded. Results: The mean age was 38.6 ± 9.95 years. There was an excellent correlation between the RCI and Swede scores (correlation coefficient: 0.94 and P value <0.0001). However, the sensitivity and NPV of Swede score (P value <0.0001) was more than RCI score (P value <0.0001) for a cut-off of 5+ for both the scores for detection of CIN-II+. Larger size of lesions (score 2) was associated with malignant cases. Conclusion: Swede score and RCI score have good correlation in detecting cervical cancer. However, Swede score is better than RCI score. Swede score of 5+ for CIN-II+, is a good screening tool, with sensitivity and NPV of 100%. The inclusion of lesion size in Swede score makes it better than RCI score.
