Cytogenetic study of 30 bladder carcinomas confirmed the heterogeneity and the complexity of the karyotypic picture in this type of tumor. Presence of numerical and/or structural chromosome aberrations was observed in all tumors. Clonal abnormalities were found in 19 cases. Chromosomes most frequently involved in changes were chromosome #1, #3 and #11(36.6%, 26.6%, and 20% of the cases respectively). Trisomy 7 and monosomy 9 were the sole abnormalities in one case each.

Abstract
Cytogenetic study of 30 bladder carcinomas confirmed the heterogeneity and the complexity of the karyotypic picture in this type of tumor. Presence of numerical and/or structural chromosome aberrations was observed in all tumors. Clonal abnormalities were found in 19 cases. Chromosomes most frequently involved in changes were chromosome #1, #3 and #11(36.6%, 26.6%, and 20% of the cases respectively). Trisomy 7 and monosomy 9 were the sole abnormalities in one case each.
