The DNA distribution pattern was determined 30 colo-rectal carcinomas. The DNA content in individual cells was measured according to a cytophotometric method based on light transmission measurement of Feulgen-stained nuclei. The DNA non diploid carcinomas were significantly more common from the left (descending and sigmoid) colon and rectum (P = 0.0002). No relationship existed between DNA pattern and age, sex, Dukes' stage, tumor grade.
