[Clinical course and prognosis in T-cell lymphoblastic tumors in children typed with Soviet-produced monoclonal antibodies].

Correlation analysis of the clinical course and prognosis was made in 56 children with T-cell lymphoblastic tumors (acute lymphoblastic leukemia and lymphosarcoma) typed with the use of monoclonal antibodies obtained in this country. The frequency of T-cell marker detection among all immunological subvariants in acute lymphoid leukemia and lymphosarcoma proved to be similar (36.6 and 37%, respectively). In acute lymphoid leukemia type T1 of tumor cells prevailed (58%), while in lymphosarcoma type T3 (63%). T2 and T3-cell lymphoblastic tumors were characterized by the most severe clinical course.
