title: [Colon carcinoma pathogenesis. An epidemiological study (author's transl)].
abstract: The mean incidence age for rectal carcinoma in women rose significantly in the township of Karlsruhe between 1971-1975 from 61,5 to 70,9 years, while the incidence age for colon carcinoma in men decreased significantly from 67,5 to 65,0 years. In the world incidence statistics of colon carcinoma in males, Karlsruhe ranks  16th (13,2 cases per 100 000 inhabitants), whereas the city ranks second for rectal carcinoma in males (18,5 cases/100 000). Prevalence patterns of gastric, colonic, and rectal carcinoma differ between individual districts of Karlsruhe. Time-related pathogenetic influence factors are discussed in extenso.
