879例女性宫颈液基细胞学检查与DNA定量分析法的对比研究

A comparative study of liquid based cytology examination and DNA quantitative analysis in 879 women

目的比较液基细胞学检查和DNA定量分析法在女性宫颈病变中的应用及其临床意义。方法对参与对比的879例妇女用宫颈刷取材,进行液基薄层制片,分别进行巴氏染色和DNA染色。对巴氏染色片做液基细胞学检查,并对DNA染色片进行全自动扫描诊断。结果对液基细胞学检查结果显示病变程度在非典型鳞状上皮细胞(ASCUS)意义不明以上病例和全自动DNA倍体分析系统检测见异倍体细胞部分病例,建议进一步做阴道镜检查及宫颈活检。28例妇女做了病理活检。以细胞诊断结果为标准,计算出细胞DNA定量分析法在ASCUS以上宫颈病变的检出率。结论细胞DNA定量分析法与液基细胞学检查组合应用,能明显提高宫颈癌及癌前病变的阳性检出率,对我国女性宫颈癌的防治具有重要的意义。

Objective To compare the application and clinical significance of the liquid based cytology examination and the DNA quantitative analysis in female cervical lesions.Methods The cervical cell samples were collected from 879 women participating in the comparison by the cervical brush and performed the the liquid-based thin layer section preparation for conducting Papanicolaou staining and DNA staining respectively.The liquid based cytology examination was performed on the Papanicolaou staining section and the fully automatic scanning diagnosis was performed on the DNA staining section.Results The cases of above atypical squa-mous cells of undetermined significance（ASCUS）detected by the liquid based cytology examination and the partial cases of hetero-ploid cell detected by the fully automated DNA ploidy analysis system were recommended to further perform colposcopy and cervi-cal biopsy.28 women were performed the pathological biopsy.With the cytological examination result as the standard,the detection rate of above ASCUS cervical lesions detected by the cellular DNA quantitative analysis was calculated.Conclusion The combined application of the cellular DNA quantitative analysis method and the liquid based cytology examination can obviously increase the positive detection rate of cervical cancer and precancerous lesion,which has important significance for the prevention and treatment of female cervical cancer in our country.
