“…According to the study of Nessa et al, the Swede score colposcopic scoring system identified significantly more CIN II and higher lesions than smear results and provided more accurate screening and selection for immediate treatment of the cervical lesions in low-resource settings 19. In addition, Nessa et al suggested that the Swede score cut-off point should be 4 for biopsy in low-resource settings as an alternative cervical screening method 19. Similarly, also in our study, low-grade lesions and high-grade lesions were detected by the Swede score colposcopic scoring system with high accuracy.…”

ObjectiveTriage with HPV genotyping has some caveats and debates for HPV positive cases other than 16 and 18. The Swede score colposcopic scoring system has not previously been evaluated in this group of patients.ObjectiveTo use the Swede score colposcopic scoring system to compare scores and final histopathological results in women who have undergone colposcopy owing to infection with high risk-HPVs other than HPV16 and 18 and to establish new cut-off values to predict pre-malignant lesions in this group of patients.MethodsThis study was conducted in 613 women undergoing colposcopic evaluation because of abnormal cervical cytology together with high-risk HPV infection. All patients referred were evaluated by an expert colposcopist, given a Swede score (using the Swede score colposcopic scoring system) by using five variables (acetowhiteness, margins plus surface, vessel pattern, lesion size, and iodine staining), and had at least one biopsy procedure (either colposcopically directed or by a loop electrical excision procedure). Sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio values, and receiver operating characteristic curves for each clinico-pathological variable to detect low-grade and high-grade squamous intra-epithelial lesions, and any squamous cell abnormality (low-grade + high-grade squamous intra-epithelial lesions) were evaluated individually.ResultsFinal histopathological results of the patients were normal in 53.2% of cases, low-grade lesions in 32.5% of cases, and high-grade lesions in 14.4% of cases. Swede score was ≥8 (median 7.97) for high-grade lesions and ≥5 (median 5.06) for low-grade lesions. The area under the curve values (95% CI) of Swede scores for low-grade and high-grade squamous intra-epithelial lesions, and low-grade + high grade lesions were 0.92, 0.98, and 0.96, respectively. A Swede score cut-off value ≥6 had a sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratios of 92%, 98%, 93%, 98%, and 50 (22.6 to 110.8), respectively, for high-grade lesions at the final pathology (P<0.001). One high-risk HPV type (except 16 and 18) was no better than another for calculating the median Swede score during colposcopy (P=0.43).ConclusionsThe Swede score colposcopic scoring system appears to be a useful tool for evaluating atypical cervical cytology in women with high-risk HPV infection other than HPV types 16 and 18.

Aim: Colposcopic indexes including Reid index and Swede score were developed to make the colposcopy more objective. The aim of our study was to evaluate the significance of colposcopic indexes in the evaluation of ASC-H cervical lesions. Methods: We carried out a cross-sectional study in the Clinic of Obstetrics and Gynecology between January 2013 and December 2018. The study included 535 women, from which 66 women had a cytological result ASC-H. Scoring of all colposcopic findings was assessed according to Reid modified index and Swede score and a composite score was determined. Frequency distributions were compared using χ 2 /Fisher exact test. Spearman rank correlation coefficient was computed between RCI and Swede score. Results: Sensitivity, specificity, positive and negative predictive value and positive likelihood ratio of modified Reid colposcopic index at a cutoff of ≥4 for the detection of HSIL+ lesions were: 86.11% (95% CI: 70.5-95.3), 83.33% (95% CI: 65.3-94.4), 86.11% (95% CI: 69.7-94.8), 83.33% (95% CI: 64.5-93.7) and 5.17 (95% CI: 2.3-11.6). Swede score with the cutoff value ≥5 showed comparable results to modified Reid index with the increased sensitivity: 94.44% (95% CI: 81.3-99.3). Conclusion: ASC-H category represents the trickiest cytological diagnosis as it is underlined with the high risk of severe cervical dysplasia. Evaluating the cervical lesion by the use of colposcopic indices helps the gynecologist to objectively evaluate all the pathologies of uterine cervix. Swede score with the cutoff value 8 also enables a 'see and treat' option in management of atypical squamous cells, cannot exclude high-grade lesions.

“…Nessa et al (14) evaluated cervical lesions in women with abnormal VIA findings using Swede score by Gynocular and colposcope. The cut-off value of 5 and greater for Swede score by the colposcope had a sensitivity of 83.3% (95% CI, 65.3%-94.7%) and specificity of 24.2% (95% CI, 17.9%-31.5%) Nessa et al (15) evaluated the accuracy in detecting cervical lesions by nurses versus doctors using a stationary colposcope and gynocular.…”

BACKGROUND Cervical cancer is a global health problem. It ranks as the 4 th leading cause of female cancer in the World, (1) the 2 nd leading cause of female cancer in India and the 2 nd most common female cancer in the women aged 15 to 44 years in World (1) and India. About 527,624 new cases are diagnosed and 265,672 cervical cancer deaths occur annually in the World. Incidence and prevalence of cervical cancer remains high in developing countries due to lack of resources, lack of effective screening programmes and poorly organised health system aimed for detecting precancerous condition before they progress to invasive cancer.Colposcopy remains the reference standard for assessing the validity of all the screening procedures for cervical cancer. Colposcopy scoring systems provide an objective diagnosis to grade the severity of premalignant lesions and select patients who require treatment. A new scoring system, Swede score, has added lesion size as a parameter.Objective-This study aimed to evaluate the diagnostic efficacy of colposcopy using Swede score and to determine the degree of correlation between colposcopy impression and histopathology. women aged 20 to 65 who met the selection criteria were included in the study. All women underwent colposcopy; the findings were scored by Swede score, biopsy taken from the abnormal areas. Patients in whom colposcopy was normal, biopsy was taken from the cervix within the transformation zone. RESULTSAccording to the Swede scoring system, 133 (60.45%) were benign cases, 64 (29.1%) women were diagnosed as LGL, 23 (10.45%) were diagnosed as HGL. As far as histologic results were concerned, 144 (65.45%) were benign showing chronic cervicitis, whereas 52 (23.64%), 24 (10.9%) were diagnosed as CIN 1 (LGL), HGL (CIN 2, CIN 3) respectively. CONCLUSIONThe 'k' value for the strength of correlation between colposcopy impression for CIN using Swede score and histopathology was k=0.73, for CIN 2+ it was k=0.92. Colposcopy by Swede score had a satisfactory sensitivity of 89.47% and specificity of 86.81% in the detection of CIN. Whereas in the detection of high-grade CIN (CIN 2+), Swede score colposcopy had a sensitivity of 91.67% and specificity of 99.49%.
