Analysis of omission diagnosis and misdiagnosis on the cervical high-grade lesions / 中国医师进修杂志

ABSTRACT

Objective To discuss the clinical value of the "three-step" diagnostic routine in the diagnosis of cervical high-grade lesions. Method The women with the abnormal thinprep cytology test (TCT) underwent colposcopy and biopsy,the pathobiology result was the diagnostic standard. The sensitivity and specificity of the cervical high-grade lesions was calculated. Results The identify rate of the cervical high-grade lesions from the abnormal TCT was 22.3% (340/1524), the sensitivity was 27.1% (92/340), the specificity was 97.5% (1154/1184). The sensitivity of colposcopy was 47.9% (163/340), the specificity of colposcopy was 96.4% (1141/1184). Conclusion TCT with high sensitivity is used for preliminary screening, the colposcopic examination is used to pinpoint and evaluate the lesions,the detection rate and accuracy of cervical high-grade lesions can be improved.
