The value of the REID scoring system in cervical cancerscreening

Abstract

This study aims to determine the value of REID scoring system in cervical cancer screening. A cross-sectional descriptive study was conducted on 84 patients who underwent screening at the Central Obstetrics Hospital from June 2021 to December 2021. Patients who met the inclusion criteria underwent clinical examination, Pap smear, HPV testing, colposcopy, and guided punch biopsy in suspected cases. The average age of the subjects in the study was 39.28 ± 9.08. Among 84 patients underwent biopsy, of which 21 patients (25%) had benign histological results. Among the malignant lesions, pre-cancerous lesions were the most common, with the proportions of CIN I, II, and III being 35.7%, 16.7%, and 10.6% respectively. Squamous cell carcinoma and glandular cell carcinoma accounted for 8.4% and 3.6% respectively. The optimal cutoff threshold of the REID scoring system for cervical cancer diagnosis was 4.5. With this cut-off threshold, the sensitivity, specificity, negative predictive value, positive predictive value, and diagnostic value of colposcopy were 76.2%, 66.7%, 48.3%, 85.7%, and 73.8% respectively. The area under the curve for the REID score at the cut-off points was 0.852 with a 95% confidence interval of 0.736- 0.969. The REID scoring system is a valuable tool in cervical cancer screening. However, to maximize the effectiveness of this tool, it is necessary to focus on the human factor and incorporate this system into a standardized training program.
