The minimumvalues were found for stage Ta and grade 1 (90.5 and 89.4) and sensitivity of FISH in other stages and gradeswas 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 associationbetween the number of cell abnormalities in chromosome 17 and the tumour stage (p value=0.02). No relationshipwas found between the type of chromosomal abnormality and grade. Thus feasibility and reliability of a FISHbased approach was confirmed for detection of UC in urine samples.}, keywords = {Urothelial carcinoma,Detection,Urine samples,chromosome abnormalities,fish}, url = {https://journal.waocp.org/article_24840.html}, eprint = {https://journal.waocp.org/article_24840_eb3ceca0e89f7059e743b037864a2e24.pdf} }
