[Clinical relevance of glucocorticoid receptors in the treatment of lymphoid neoplasias].
A generalized view on the mechanism of steroid hormone action is presented with special emphasis on glucocorticoids and their lymphocytolytic effects. The present knowledge on the structure and function of glucocorticoid receptors is reviewed. Following hormone binding, the receptor complex is activated to a form which is able to interact with chromatin or DNA. Several types of receptor mutants have been obtained in an animal cell culture system which allows selection of cell variants. The biochemical analysis of these mutants helped to establish a domain model of receptor structure. The quantitative effect of receptor numbers and hormone activity on lymphocytolysis is described in a cell culture model system and the results are discussed in view of the rational treatment of lymphoid neoplasia with glucocorticoids. The clinical experience with glucocorticoids alone and in combination therapy with cytostatic drugs is summarized. Our special emphasis is on acute lymphoblastic leukemia and malignant lymphoma as patients with these diseases can now be treated with remarkable success rates.
