AIMS, BACKGROUND AND STUDY DESIGN: Few studies have investigated the karyotypes of colorectal carcinomas with emphasis on the correlation between cytogenetic findings and clinicopathologic features. The aim of our study involving 20 colorectal adenocarcinomas was to determine their genomic alterations at the chromosomal level by correlating the cytogenetic findings with the extent of DNA damage and clinicopathologic parameters and to compare the results with those of healthy controls. RESULTS: Cytogenetic evaluation of patients and controls revealed 10 abnormal karyotypes in patients with adenocarcinomas located in the rectum, sigmoid and rectosigmoid regions. Four had numerical and six had structural abnormalities. CONCLUSIONS: Statistical analysis revealed a significant difference compared with controls (P <0.01). The karyotypes and the extent of DNA damage assessed by the comet assay were also significantly correlated with tumor stage (P <0.01) using the Kruskal-Wallis non-parametric test, while no statistical significance was observed in relation to patient age and smoking.
