Methods: A total of 674 patients with cervical abnormalities who underwent HPV E6/E7 mRNA and TCT in Yan’an people’s Hospital from January 2018 to December 2022 were selected. With the histopathological results as the gold standard, the screening value of different examination methods for cervical cancer was analyzed. Results: Histopathological biopsies showed that the diagnostic concordance of HPV E6/E7 and TCT was 62.42%, and the sensitivity, specificity and accuracy of HPV E6/E7, TCT and colposcopy in detecting HSIL + SCC were all lower compared with the combined test, and the differences were statistically significant (P < 0.05). Conclusion The combination of HPV E6/E7 mPNA and TCT improve the value of screening for cervical cancer and may help in better clinical diagnosis and treatment.展开更多

文摘目的探讨在HPV阳性女性中,液基细胞学、DNA倍体分析及P16/Ki-67双染检测对宫颈癌前病变的分流作用。方法回顾性分析2021年5月至2022年12月在我院妇科行阴道镜及宫颈活检的妇女590例。患者高危人乳头瘤病毒(human papilloma virus,HPV)检测阳性,且行液基细胞学(liquid-based cytology,LBC)、DNA倍体分析、P16/Ki-67双染3种检查,对上述3种方法的灵敏度、特异性、受试者工作特征(receiver operating characteristic,ROC)曲线进行统计分析。结果液基细胞学、DNA倍体分析和P16/Ki-67双染3种筛查方法对宫颈癌前病变的灵敏度分别为84.2%、77.5%、76.4%,特异性分别为40.7%、49.2%、70.1%,曲线下面积(area under the curve,AUC)分别是0.625、0.634、0.733,其中,P16/Ki-67双染检测显著优于液基细胞学检查及DNA倍体分析(P<0.0001)。结论本研究认为,在HPV阳性女性中,P16/Ki-67双染检测的分流效果最佳。
