Molecular cytogenetic analysis of urothelial carcinomas using urine samples.

Abstract
Urinary cells obtained from voided urine specimens of 46 patients with urothelial carcinomas (UCs) and 10 normal individuals were analyzed with 3 different centromeric fluorescence in situ hybridization (FISH) probes. The overall sensitivity of cytology was 48.9% compared to 95.7%with the FISH technique. The minimum values were found for stage Ta and grade 1 (90.5 and 89.4) and sensitivity of FISH in other stages and grades was 100%. Chromosome 3 demonstrated the most frequent chromosomal abnormality in all samples (43%), followed by chromosome 17 (32%) and chromosome 7 (25%). There was a statistically significant association between the number of cell abnormalities in chromosome 17 and the tumour stage (p value=0.02). No relationship was found between the type of chromosomal abnormality and grade. Thus feasibility and reliability of a FISH based approach was confirmed for detection of UC in urine samples.
