Clinical application of liquid-based cytology combined with DNA quantitative analysis in cervical lesions screening / 重庆医学

ABSTRACT

Objective To investigate the application value of the liquid‐based cytology test (TCT) and the DNA quantitative analysis in cervical lesions screening .Methods 2 883 cases of TCT ,1 742 cases of DNA quantitative analysis and 333 cases of TCT combined with the DNA quantitative analysis were performed the retrospective analysis for investigating their clinical significance in diagnosing the cervical lesions .Results The positive coincidence rates of TCT ,DNA quantitative analysis and their combined detec‐tion were 43 .86% ,68 .04% and 81 .16% respectively .There was statistically significant difference in the positive coincidence rates for diagnosing CIN Ⅰand above between TCT and the DNA quantitative analysis (P<0 .01);the positive coincidence rates of the combined detection had statistical difference compared with TCT and the DNA quantitative analysis (P<0 .01) .The sensitivity and the specificity of TCT for discovering the cervical lesions were 69 .44% and 92 .42% respectively ;which of the DNA quantitative a‐nalysis were 85 .71% and 87 .89% respectively ;while which of combined detection were 96 .55% and 95 .89% respectively .Conclu‐sion The DNA quantitative analysis and TCT have the higher clinical diagnostic value in the cervical lesion screening .Their com‐bined detection can more effectively increase the detection rate of cervical lesions .
