[Osteogenic sarcoma in children: clinico-immunological correlations].

Initial immunologic status in children suffering osteogenic sarcoma was retrospectively evaluated versus such parameters as site and extent of tumor, and clinical course. A complex of disorders in the immunologic system was established in osteogenic sarcoma patients. Such characteristics as levels of active, theophylline--sensitive and levamisole--reactivated T-cells were found clinically valuable and prognostically significant. These parameters may betray response of high- and low-affinity E-receptors of lymphocytes to serum factors of tumor growth.
