[The colorectal carcinoma risk factors].
Colorectal carcinoma constitutes the second, as for the rate, death cause due to a malignant disease both in the western countries and in Poland. Despite deep knowledge concerning morphogenesis and spread of colorectal carcinoma as well as vast achievements in surgery, chemo- and radiotherapy, the percentage of 5-year-survivals still reaches 40%. According to most authors there are 4 risk factor categories: epidemiological, intestinal, dietetic, and mixed. It is well-known that colorectal carcinoma, like neoplasms localized in other organs and systems, is a disease, in which genetic mutations of somatic cells are the molecular base/source of the disease. The inner innervation of the colon seems to play an important role in carcinoma pathogenesis and spread. At present, 80% of colorectal carcinomas are diagnosed in the advanced stage, with infiltration exceeding the intestinal wall or spreading to neighboring organs, which gives full clinical symptoms. The prognosis as to survival and disease progression is usually poor. Therefore, the ways of early diagnosis, monitoring, and the knowledge of etiological factors are so important in medical practice.
