Abstract Although a bladder cancer-specific abnormality in chromosomes or genes has not been reported, chromosomal regions that tend to become abnormal have been recognized. In this study, we investigated abnormalities in chromosomes 8 and 11. There were 27 patients with bladder cancer, 16 males and 11 females, who participated in this study. Abnormalities in chromosomes 8 and 11 were investigated by the fluorescence in situ hybridization (FISH) method. Probes used in this study were chromosome 8α-satellite and chromosome 11α-satellite (Oncor Co.). Of 27 cases, 15 cases were positive for chromosome 8 (55.6%) and ten cases were positive for chromosome 11 (37.0%). Since the FISH method detects chromosomal abnormality by the number of signals generated in cancer cells, this method is objective and simple and thus may be applicable in clinical practice.
