FAMILIAL AGGREGATION OF MALIGNANT LYMPHOMAS
Familial aggregation of malignant lymphomas is encountered rather commonly -only in 0.7-3.0% of cases. The incidence of non-Hodgkin lymphoma and Hodgkin lymphoma in one family (in parent-child and brother-sister pairs) is highest. In this case, the disease is generally characterized by the aggressive course and more frequent occurrence of the lymphomas in younger infants than in their parents. The paper describes cases of aggregation of familial lymphomas in the patients who have been treated at the N.N. Petrov Research Institute of Oncology, Ministry of Health of the Russian Federation.
