Application of DNA-image cytometry in the diagnose of urothelial cell carcinomas / 实用医学杂志

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.
