ABSTRACT
Objective To determine the value of DNA image cytometry (DNA-ICM) in diagnosis of breast cancer.Methods Totally 187 patients with breast or axillary mass admitted from Aug.2014 to Oct.2017 were included in the study.Fine-needle aspiration cytology (FNAC),DNA-ICM and liquid-based cytology (LBC) were employed.The results showed that 100 cases were breast cancer patients and 73 cases were benign patients.DNA-ICM and LBC were used to compare the sensitivity and specificity of the two methods.Results The sensitivity and specificity were 82.0％ and 100％ for DNA-ICM,and 69.0％ and 97.3％ for LBC.The sensitivity of DNA-ICM was significantly higher than that of LBC (P=0.033).In breast tissue,the sensitivity and specificity of DNA-ICM were 83.3％ and 100％,and they were 64.8％ and 97.5％ for LBC.The difference of sensitivity was statistically significant (P=0.028).In axillary tissue,the sensitivity and specificity of DNA-ICM were 80.4％ and 100％,and they were 73.9％ and 97.0％ for LBC.The difference was not statistically significant (P=0.456).The sensitivity of joint detection was 93.5％,significantly higher than that of LBC alone (P=0.024).The effect of joint detection was better than that of LBC.Conclusion DNA-ICM method is of great value in the diagnosis of breast cancer,which can be combined with LBC in diagnosis of breast cancer.
ABSTRACT
Objective To investigate the value of DNA-image cyt-ometry (DNA-ICM) in the diagnosis of urothelial cell carcinomas (UCC). Methods Totally 162 voided urine specimens (92 cases from urothel-ial car-cinomas patients and 70 cases from benign urinary system diseases patients ) were detected with DNA-ICM and liquid-based cytology (LBC), respectively. Results The sensitivity and specificity of DNA-ICM were 65.2%and 100% respectively in the diagnosis of UCC but those of LBC were 27.2% and 98.6%, respectively. The sensitivity of DNA-ICM was significantly higher than that of LBC in the diagnosis of UCC (P 0.01). Conclusion DNA-ICM, which improves the positive rate of urinary cytology, has great application value in the diagnosis of urothelial cell carcinomas and it is an effective screening method for urothelial cancer in diag-nosis and follow-up.
ABSTRACT
Objective To evaluate the application of DNA image cytometry in screening cervical intraepithe-lial neoplasia and cervical cancer.Methods 80 patients with cervical intraepithelial neoplasia admitted during No-vember 2012 and November 2014 were involved in this study.The samples from all the patients were taken by cervix brushes and prepared for 2 slides:one for liquid-based cytology staining, read by cytologist, and the other for Thi-onin-Feulgen staining, tested by DNA image cytometry.The biopsy was performed with direction of colposcopy if one test was positive to verify the sensitivity and specificity of the two methods of staining.Results 70 cases were positive by DNA image cytometry and 27 ones were positive by liquid-based cytology.There was statistically signifi-cant difference in the sensitivity between the DNA image cytometry and the liquid -based cytology ( 94.8% vs. 38.8%;p<0.05), but no difference in the specificity between them (99.6%vs.99.8%).Conclusion Besides its good specificity, DNA image cytometry is more sensitive in screening cervical intraepithelial neoplasia and cervical cancer.
ABSTRACT
Objective To investigate the value of DNA image cytometry in thediagnose of benign and malignant pleuroperitoneal fluids by comparing with the liquid-based cytological results. Methods There were 417 cases in-volved in this study. Pap stain for cytology analysis and feulgen stain for DNA image cytometry were used to identify benign and malignant pleuroperitoneal fluids respectively,then compared the results of the two methods. Results Clinically or pathologically,213 were classified as malignant and the other 204 as benign. The sensitivity, specifici-ty,accuracy, positive predictive value and negative predictivevalue of DNA image cytometry were 89. 7%,100%, 94. 7%,100%,and 90. 3%,respectively. However,the sensitivity,specificity,accuracy, positive predictive value and negative predictive value of liquid-based cytology were 63. 4%, 81. 9%, 72. 4%, 78. 5%, and 68. 2%, re-spectively. There were significant differences in thesensitivity, specificity,accuracy, positive predictive value and negative predictivevalue. Conclusion DNA image cytometry has great application value in the diagnosis of benign and malignant pleuroperitoneal fluids, and can increase the positive rate, reduce misdiagnosed rate with liquid-based cytology.
