Abstract
Prolactinomas are the most common secreting adenomas of the pituitary. In 20% of cases resistance to dopamine-agonists treatment is observed. Medical therapy resistance causes progression of pathological symptoms of hyperprolactinemia and negative topographic and anatomical changes of prolactinoma. The causes of ineffectiveness of dopamine agonists therapy are not fully understood as well as approaches to managing patients require clarification. Current concepts of resistance are based on the data obtained as a result of surgery or after a period of long-term ineffective therapy. Thus, it is very important to find methods of assessing the sensitivity of prolactin-secreting adenomas to drug therapy before surgical treatment. Genetic and immunohistochemical studies find special place among these methods, making it possible to predict adenoma's response to drug therapy at early diagnostic stage. Obtained results will allow us to form personalized algorithm for managing patients.
期刊介绍：
Since 1955 the “Problems of Endocrinology” (or “Problemy Endocrinologii”) Journal publishes timely articles, balancing both clinical and experimental research, case reports, reviews and lectures on pressing problems of endocrinology. The Journal is aimed to the most topical issues of endocrinology: to chemical structure, biosynthesis and metabolism of hormones, the mechanism of their action at cellular and molecular level; pathogenesis and to clinic of the endocrine diseases, new methods of their diagnostics and treatment. The Journal: features original national and foreign research articles, reflecting world endocrinology development; issues thematic editions on specific areas; publishes chronicle of major international congress sessions and workshops on endocrinology, as well as state-of-the-art guidelines; is intended for scientists, endocrinologists diabetologists and specialists of allied trade, general practitioners, family physicians and pediatrics.
