[Immunophenotype of blood lymphocytes in elderly patients with laryngeal cancer]

In a group of 42 patients with surgically treated laryngeal carcinoma, who were divided into those before their 50 and after 60 years of age, main lymphocyte subsets of peripheral blood lymphocytes were assessed by means of flow cytometry. In the group after 60 years of age significantly increased percentage and raised total number of NK (natural killer) cells were found. In the whole group increased total number of all lymphocyte subsets was found. These data indicate that older patients despite an increased number of total to lymphocytes NK cells show higher percentage and total number as compared with normal population at that age.
