Analysis of Cervical Thinprep Liquid Based Cytology Test in Central and Western Inner Mongolia

Objective:Through investigating cervical cancer and cervical intraepithelial neoplasia incidence and epidemiologic feature,assess the investigation of the incidence of cervical cancer statistics for the record retrieva of central and western Inner Mongolia.Methods:From erode area 66981 cases of cervical lesions were detected and diagnosed with TCT and TBS.The samples of atypical squamous cells(ASC) and more severe than ASC lesions were classified into positive cases,then multi-cervix tissues were biopsied by colposcope.Compared with pathological examination results of cervical biopsies,analysis the incidence trends of cervical lesions of age group,and summary the incidence law of cervical lesions of the han women and mongolian.Results:The satisfactory rate of TCT samples was 99.9%(66911/66981)and the positive rate of abnormal epithelial cells diagnosed by TCT was 8.17%(5466/66911).Among the 5466 cases,there were 47 cases(0.07%) of CA,301cases(0.45%) of HSIL,871 cases(1.30%)of LSIL,635 cases(0.95%) of ASC-H and 3612 cases(5.4%) of ASCUS and AGUS.The pathological positive rates of CA,HSIL,LSIL,ASC-H and ASCUS+AGUS were 100%,97.83%,93.07%,72.79% and 37.39%,respectively.The coincident rate of two examination methods was 100% for CA,90.58% for HSIL,59.34% for LSIL,40.18% for ASC-H and ASCUS+AGUS for 37.69%.Compare with the Mongolian women and han showed that mongolian women had high incidence of cervical lesions.Different age groups of women have different Incidence of cervical lesions.Conclusion:①TCT and TBS can accurately detect cervical cancer and precancerous lesions.②TCT applies to large scale screening of cervical lesions,three steps diagnosis can obviously elevate the detection rate of cervical lesions.③Premalignant lesion rates and age of cervical cancer were positively correlated.④The morbidity rate of the cervical lesions and precancerous lesions among Mongolia woman are higher than that of han woman.⑤Screening is the main method to prevent and control cervical cancer.
