Abstract
Cytogenetic analysis of resected bladder tumors was performed in 30 patients. None of these patients had previous irradiation or chemotherapy. Direct chromosome preparations were made. Of the 30 preparations, 20 had chromosome abnormalities. We have observed a good correlation between the chromosome abnormalities and the stage/grade of the tumors. Patients were followed from 3 to 23 months. During this period, 61 % of the patients with nonin vasi ve or submucosal invasive bladder tumors and chromosome abnormalities have had recurrences. The existence of a good correlation between chromosomal abnormalities and the capacity of the neoplasm to recur was confirmed.
