RESUMEN
Objective To explore the clinical application value of flow -cytometry combined with colpo-scope ultra high frequency electric knife for diagnosis of uterine cervix carcinoma ( UCC) and cervical intraepitheli-al neoplasia(CIN).Methods A total of 705 cases was included in this study who were screened from April 2014 to April 2016 and accepted colposcopy biopsy .DNA flow cytometry was performed to determine DNA index ( DI) and proliferative index ( PI) .Results Colposcopy diagnosis results showed that the detection rate of CINⅠ,CINⅡ,CINⅢ/CIS and UCC were 62.2%,78.0%,62.2% and 78.0% respectively.The sensitivity and specificity were 87.7%(213/243)and 90.2%(417/462)for DNA ploidy test using flow-cytometry.DI and PI of CINⅠ, CINⅡ,CINⅢ/CIS and UCC increased gradually with significant differences (P<0.05).Conclusion Flow-cytometry combined with colposcopy biopsy may be a useful tool for cervical cancer screening in developing coun -tries and has a competitive sensitivity and specificity ,which is worthy of popularization and application .
RESUMEN
Objective To explore the difference of the results between pup smear and liquid-based cytology (TCT) in cervical lesions.MethodsA total of 150 patients undergoing routine cytology were enrolled in the department of obstetrics and gynecology in Hangzhou Wuyunshan sanatorium from May 2015 to December 2016.The patients were treated with liquid-based cytology (TCT) and Papanicolaou Smear examination;and liquid-based cytology method as the study group, and Pap smear the control group.The difference of the diagnostic results between the two groups were compared.ResultsThe positive rate of ASCUS detection, LSIL detection rate and HSIL detection rate were significantly higher in the study group than those in the control group (P<0.05).The difference between the two groups was statistically significant (P<0.05).Compared with the results of colposcopic biopsy, the diagnosis of LSIL coincidence rate in the study group was significantly higher than that in the control group, the difference between the groups was statistically significant (P<0.05).ConclusionCompared with pap smear examination, liquid-based cytology has a more obvious advantage in cervical lesions, which can significantly improve the positive rate of cervical lesions, reduce the false negative results, with a higher diagnostic compliance rate, and therefore worthy of clinical application.
RESUMEN
Objective To compare the diagnostic clinical significance between loop electrosurgical excision procedure (LEEP) and colposcopical biopsy for cervical intracpithelial neoplasia(CIN). Methods 130 cases of pa-tients diagnosed as CIN under colposcopical biopsy were treated by LEEP in court of gynecology clinic. The conven-tional pathologic diagnosis was recorded in all conization specimens. Results The coincidence rate between colpo-scopical biopsy and LEEP biopsy in CIN Ⅰ, CIN Ⅱ, CIN Ⅲ (not comprised carcinoma in situ) was 55.26%,66.10% ,78.79% respectively;The total coincidence rate was 66.15%. The accuracy of colposcopic biopsy for diag-nosing CINⅢ was higher than that for CIN Ⅰ and CIN Ⅱ,but there was no statistical difference. Conclusion Colpo-scopical biopsy for cervical lesions can be achieved for the frist time the results of pathology, have limitations. LEEP biopsy can compensate partially the deficiency of colposcopic biopsy. In a dear diagnosis of CIN, LEEP biopsy and colposcopical biopsy may complement each other, and achieve thcrpeutic effects.
