title: [Estradiol-17beta, sex steroid-binding globulin and the cellular and humoral immunity indices in young women with breast cancer].
abstract: Blood serum levels of sex steroid-binding globulin (SSBG), free and SSBG- and albumin-binding fractions of estradiol-17 beta as well as some indexes of cellular and humoral immunity were compared in 25 young female patients with stage 1-3 breast cancer and controls. No significant difference in SSBG and free estradiol-17 beta fraction as well as free estrogen index was established between patients and controls. In the patient group, a direct correlation was established between free estradiol-17 beta fraction level and that of mature T-cells expressing CD3 antigen and between SSBG level, on the one hand, and total level of T-cells (CD7 antigen) and that of T-suppressors (CD8 antigen-containing cytotoxic lymphocytes), on the other. An inverse correlation was established in the same group between SSBG level and that of B-cell markers expressing CD3 and 7 antigens and IgM mu-chain. In the follicular and lutein phases of the menstrual cycle, a difference in the degree of correlation between total estradiol-17 beta level and immunologic indexes was established between breast cancer patients and controls.
