Abstract
Background
Cervical cancer screening algorithms are increasingly focused on Human Papillomavirus (HPV)‐based screening while the accuracy of using abnormal cytological findings to detect dysplastic lesions still remains important. This retrospective study correlated the results of conventional cervical cytology, colposcopy guided biopsy, and cold knife conization (CKC) procedures performed in a tertiary center.
Materials and Methods
Data from 9399 patients who underwent screening with conventional cervical cytology between 2010 and 2019 was obtained from the hospital registry. Abnormal cervical cytology and high‐risk HPV DNA genotypes were recorded and their colposcopic and CKC pathology was determined.
Results
Two hundred and ninety two patients underwent colposcopy for abnormal cervical cytology and/or high‐risk HPV positivity. One hundred and twenty three patients were positive for High‐risk HPV. Abnormal cervical cytology was detected in 216 patients. The most common cytological anomaly was atypical squamous cells of undetermined significance (ASCUS) found in 9399 patients (1.39%). It was determined that conventional cytology had a sensitivity of 70.8% and a specificity of 62.2% for the detection of low‐grade lesions, while it had a sensitivity of 72.4% and a specificity of 86.0% for the detection of high‐grade lesions. CKC was applied to 68 patients who were diagnosed with high‐grade squamous intraepithelial lesions (HSIL) as a result of the colposcopy. As a result of CKC, a high‐grade lesion was detected in 73.5% of these patients.
Conclusion
Conventional cervical cytology and colposcopy exhibited higher accuracy as the severity of lesions increased. Detection of HPV may prevent unnecessary surgical procedures, especially with ASCUS.
