[The effect of age and sex on localization, tumor stage and prognosis of colorectal carcinoma].

In a retrospective study including 946 cases with colorectal cancer we analysed age, sex, distribution and stage. There was a significant higher prevalence in women and in all tumor stages women were older than men. The frequencies of Dukes C and proximal colon cancer was significantly higher in women. In older patients we found an increasing incidence of proximal cancer. Instead of tumor stage the age, sex and distribution showed no influence on the outcome.
