[Study of cellular immunity in patients with testicular teratoblastoma by the method of rosette formation].

In 23 patients with teratoblastomas of the testes the authors studied nonspecific reactivity of T-lymphocytes by means of the reaction of spontaneous rosette-formation. A definite correlation was shown between the reaction indices, chorionic gonadotropin, the Abelev reaction and clinical course of the disease. It is concluded that the complex therapy should be conducted under the control of the corresponding immunological indices.
