[Hormones, autocrine and paracrine regulators of tumor growth in osteosarcoma].
The data on 300 patients, aged 14-56, treated at the Center's Clinic have been evaluated. They include findings on androgen metabolism, basal level of secretion of sex steroid hormones in blood serum and their receptors in tumor, blood concentrations of sex steroids, binding globulin and pituitary hormones, arachidonic acid metabolism, expression of epidermal growth factor and its receptors and ligands, soluble Fas-antigen, vascular endothelial growth factor as well as calmodulin and cAMP levels in sarcoma. New trends of research in pathogenetic methods of treatment of osteosarcomas used in practice of oncology have been identified. Among them are androgen metabolism regulation, correction of the cyclooxygenase pathway of arachidonic acid metabolism, expression of epidermal growth factor and its ligands and neoangiogenesis in tumor.
