The results of treatment were compared with the clinical, immunophenotypic and radiological features of somatotrophic tumors.</italic></p> <p><bold><italic>Results. </italic></bold><italic>It was found that densely granulated somatotrophic tumors (DGST) were characterized by a pronounced expression of the 2nd subtype somatostatin receptors (SR) and good sensitivity to SA1, while sparsely granulated somatotrophic tumors (SGST) were larger, with low expression of the 2nd subtype SR and resistance to SA1. During radiological examination, DGST and SGST showed comparative hypo- or hyperintensity of the tumor signal on T2-weighted MRI. Based on the results of SA1 treatment, biochemical remission was achieved in patients with DGST, while disease activity remained in patients with SGST.</italic></p> <p><bold><italic>Conclusion.</italic></bold><italic> The results of the work confirm the existence of fundamental clinical, morphological and radiological differences between DGST and SGST, as well as the need for a differentiated approach to the pharmacotherapy of acromegaly. The magnitude of the decrease in insulin-like growth factor-1 after 3–6 months of treatment of more than 55% of the initial level was an additional predictor of the long-term effectiveness of SA1. The introduction of the indicator of the relative intensity of the tumor signal on T2-weigthed MRI into clinical practice will improve the diagnosis of acromegaly and optimize the treatment strategy.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование. </italic></bold><italic>Акромегалия является гетерогенным заболеванием, объединяющим множество гистологических подтипов соматотрофных опухолей, различающихся по клинико-патологическим проявлениям, конечному размеру, сценарию развития, иммунологическому профилю и чувствительности к лечению.</italic></p> <p><bold><italic>Цель исследования: </italic></bold><italic>проведение комплексной клинико-морфологической и радиологической стратификации соматотрофных опухолей с целью уточнения опухолевого морфотипа и прогнозирования успешности предлагаемого лечения.</italic></p> <p><bold><italic>Методы. </italic></bold><italic>Обследованы 82 больных акромегалией, перенесших нерадикальную аденомэктомию и длительно получавших аналоги соматостатина 1-й генерации (АС1). Результаты лечения были сопоставлены с клиническими, иммунофенотипическими и радиологическими особенностями соматотрофных опухолей.</italic></p> <p><bold><italic>Результаты. </italic></bold><italic>Установлено, что плотногранулированные соматотрофные опухоли (ПСО) отличались выраженной экспрессией 2-го подтипа (п/т) соматостатиновых рецепторов (СР) и хорошей чувствительностью к АС1, тогда как редкогранулированные соматотрофные опухоли (РСО) отличались бòльшими размерами, низкой экспрессией 2-го п/т СР и резистентностью к АС1. При радиологическом исследовании ПСО и РСО проявляли сравнительную гипо- или гиперинтенсивность опухолевого сигнала на Т2-взвешенных изображениях (ВИ) МРТ. По итогам лечения АС1 у больных ПСО достигнута биохимическая ремиссия, тогда как у пациентов с РСО сохранялась активность заболевания.</italic></p> <p><bold><italic>Заключение.</italic></bold><italic> Результаты работы подтверждают наличие принципиальных клинико-морфологических и радиологических различий между ПСО и РСО, а также необходимость дифференцированного подхода к фармакотерапии акромегалии. Величина снижения инсулиноподобного фактора роста-1 через 3–6 месяцев лечения более 55% от исходного уровня является дополнительным предиктором долгосрочной эффективности АС1. Внедрение показателя относительной интенсивности опухолевого сигнала на Т2 ВИ в клиническую практику позволит улучшить диагностику акромегалии и оптимизировать лечебную стратегию.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>acromegaly</kwd><kwd>somatotrophic tumors</kwd><kwd>somatostatin receptor subtypes</kwd><kwd>T2-weighted MRI images</kwd><kwd>drug therapy</kwd><kwd>somatostatin analogues</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>акромегалия</kwd><kwd>соматотрофные опухоли</kwd><kwd>подтипы соматостатиновых рецепторов</kwd><kwd>Т2-взвешенные МР изображения</kwd><kwd>медикаментозная терапия</kwd><kwd>аналоги соматостатина</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Akirov A., Asa S.L., Amer L., et al.
