No significant correlation was found with Dukes' stage (P= 0.15), but a highly significant correlation was obtained with DNA index > 1.30 (P<0.0001) as well as 17p loss (P< 0.002). p53 content was also significantly different when it was compared to tumour site (P<0.03), with a considerably reduced incidence in the proximal colon (42.1% positive cases) compared to an average of 74.8% in the distal seg- ments. r- U- 0 30 60 FL2 b 0 30 60 FL2 C 0 30 60 FL2 Figure 4 p53/DNA FCM results for a tumour of the rectum (DNA index 1.15).
