OBJECTIVE: To evaluate the 2 methods of cytologic screening to detect abnormalities of the cervical epithelium. METHODS: This study with 3 groups of women was performed at Selcuk University Meram Medical School between January 2004 and March 2006. In one group (paired sample for specimen collection) women were screened with conventional cytology; in another group (paired sample for specimen collection) they were screened with liquid-based cytology; and in the third group (split sample for specimen collection) they were screened by both methods. RESULTS: The rate of unsatisfactory results was lower in the liquid-based than in the conventional cytology group (6.1% vs. 2.6%; P<0.05). More smears containing atypical squamous cells of undetermined significance were detected by the liquid-based method, but the difference was not statistically significant. Also, no statistically significant differences between liquid-based and conventional cytology were observed in the detection of other epithelial abnormalities (P>0.05). CONCLUSION: The liquid-based and conventional cytology methods were found to be equivalent in the detection of cervical epithelial abnormalities. 相似文献

OBJECTIVE: The purpose of this study is to evaluate a modified MonoPrep2 (MP) of liquid-based cytology (LBC) to search for a less expensive alternative technique usable for screening of cervical cancers. STUDY DESIGN: Cervicovaginal direct-to-vial samples from 1218 consecutive patients were processed with the modified MP technique and the results were compared with those of currently popular ThinPrep Pap test (TP) technique. RESULTS: Both MP and TP methods provide uniformly spread thin layers of cells without cellular overlap or significant obscuring elements. The diameter of the circular area was 20 mm in MP and 22 mm in TP. Obscuring factors were slightly more frequent in MP but not enough to affect interpretation. Thirteen specimens were excluded from the study because of poor specimen quality in MP. In 1205 patients, there was an absolute agreement in results (the Bethesda diagnosis system) between the two methods, and discordances were observed in only 18 (1.5%) in 1187 cases (98.5%). Furthermore, there was no significant difference in diagnostic accuracy in histopathologic correlation between the two methods. The sensitivity of MP was slightly lower than that of TP, and the specificity of MP was higher than that of TP. A human papillomavirus (HPV) test with polymerase chain reaction (PCR) using broad-spectrum probes has yielded good results in both MP and TP samples. CONCLUSIONS: The modification of the MP method gave comparable results to those of TP in terms of smear quality, cytologic diagnostic evaluation, and biopsy correlation with much less cost. The modified MP offers a cost-effective alternative to the currently popular expensive techniques of liquid-based cytology practical for cervical cancer screening. 相似文献

Objective
The objective of this study was to evaluate the impact of introducing HR-HPV testing in cytology regarding cervical cancer screening practice.Methods
A pooled analysis of liquid-based cytology (LBC) and HR-HPV testing using data from 13 population-based cervical cancer screening studies conducted in China was performed. Participants (n = 25,404) received LBC and HR-HPV testing. Women found to be positive on screening were referred for colposcopy and biopsy. The effectiveness of screening strategies that use: LBC with HR-HPV triage for atypical squamous cells of undetermined significance (ASC-US), HR-HPV testing with cytology triage for HPV positive tests, or LBC and HPV cotesting was compared with that of LBC screening alone.Results
LBC with HR-HPV triage for ASC-US had similar sensitivity compared with LBC alone, but significantly increased specificity for both cervical intraepithelial neoplasia grade 2 or worse (CIN2 +) and CIN3 or worse (CIN3 +) endpoints, and had the best balance between sensitivity and specificity among the strategies. LBC and HR-HPV cotesting had the highest sensitivity and negative predictive value (NPV) and could permit a safe extension of screening intervals. Through the use of an immediate colposcopy threshold of ASC-US or worse for HR-HPV positive women and the use of a raised threshold of low-grade squamous intraepithelial lesion (LSIL) or worse for HR-HPV negative women, LBC and HR-HPV cotesting could provide the same effectiveness as LBC testing with HR-HPV triage for ASC-US at baseline tests.Conclusions
The results of the current study support the use of the cervical cancer screening guidelines in China. 相似文献18.

OBJECTIVE: To evaluate the sensitivity and accuracy of 4 screening methods for cervical neoplasia. METHODS: Cervical samples from 450 women were evaluated for human papillomavirus DNA with a second-generation hybridization assay. Visual inspection, colposcopy, and liquid-based cytology were also performed for 273 of these women. The sensitivity, specificity, efficiency, positive predictive value (PPV), negative predictive value (NPV), Youden index, and kappa value of the different screening methods were compared. RESULTS: Liquid-based cytology was superior in specificity (98.63%) and PPV (92.86%) to visual inspection and colposcopy, while human papillomavirus DNA testing was superior in sensitivity (88.89%) and NPV (97.10%) to visual inspection and colposcopy. The best concordance with histologic findings was achieved by using both liquid-based cytology and viral DNA hybridization. CONCLUSION: Visual inspection and colposcopy should not be used when screening for early stage cervical lesions. The DNA hybridization assay is the best choice in primary screening, if available. Screening should begin at the age of 20 years. 相似文献
