[Hereditary colonic cancer. Analysis of 3 families at risk].
Hereditary colorectal cancer is a clearly identified entity today; it is transmitted as a dominant autosomal heritage, and represents about 25% of large bowel malignancies. The poor prognosis of this tumor, one of the most frequent in Western Countries, despite the improvements in therapeutic field, is due to a delated diagnosis that affects an advanced stage of disease in which the results of treatment are significantly worse, whereas cumulative 5-year survival rate is 35% vs 95% in early stage tumors. Existence of an inherited cancer, even in the absence, at present, of specific biomarkers, allows to identify a high risk population in which early diagnosis of colorectal cancer is possible, on the basis of anamnestic and clinical features. Only in this way, with the extension of the results to general population, prognosis of colorectal cancer will be improved.
