[Clinico-genetical studies of colonic cancer. III. Primary multiple malignant neoplasms].
The results of clinico-genealogic analysis of 46 patients with primary-multiple malignant neoplasms are given (among them 16 patients with primary-multiple malignant neoplasms of colon cancer and 30 patients with one or more neoplasms in combination with different malignant tumors of other organs). The values of segregation rates obtained for primary-multiple malignant neoplasms are lower than theoretically expected for simple monogeneous types of inheritance. The relation analysis of primary-multiple malignant neoplasms and colon cancer revealed that these tumors are likely to appear among relatives of probands under the influence of the same genetic system of determination. Risk of the colon cancer development for relatives of the patients with primary-multiple malignant neoplasms is higher than for relatives of the patients with colon cancer.
