title: [Prognosis of colonic and rectal cancer under selection free conditions (author's transl)].
abstract: Incidence of cancer of colon and rectum shows increasing tendency in G.D.R. It is necessary to orientate practical medicine in this direction respecting future needs in scientific and therapeutic view. Published results of treatment deceive in true prognosis, because they are commonly from special hospitals. Effects of selection, lack of uniform definitions and faults in statistics may lead to unfounded optimism. Reports on treatment results which are free from selection bies are rare till now. The National Cancer Registry in the Erfurt Region gave crude absolute five-year-survival rates of 10.3% in colonic cancer and 10.8% in rectal cancer for the years 1960-1966. Radical operations resulted in survival rates of 26.4% and 27.4%. The author draws conclusions concerning education of general practitioners, improvement of diagnostic facilities, and centralized organization of special medical care for cancer patients.
