Так, если 5-летняя общая выживаемость при лейомиосаркомах в целом составляет 64 %, то при диссеминированном процессе она снижается до 10-16 %. Основным методом лечения, определяющим прогноз, является радикальная операция. Для лечения нерезектабельных лейомиосарком используются химиотерапия и таргетная терапия. Кроме того, одной из альтернативных опций лекарственного лечения лейомиосарком матки является гормонотерапия. Ее применение возможно при положительном статусе рецепторов эстрогена и прогестерона в опухоли, а само наличие экспрессии рецепторов к стероидным гормонам является благоприятным прогностическим признаком. В данной статье представлен собственный анализ частоты экспрессии рецепторов эстрогена и прогестерона в лейомиосаркомах различной локализации, а также результатов гормонотерапии.</p></abstract><trans-abstract xml:lang="en"><p>Leiomyosarcoma (LMS) is a group of malignant mesenchymal tumors with variable behavior and prognosis. in general, 5-year overall survival rates for 64 %o, but in case of disseminated disease it decreases to 10-16 %. The main treatment modality that determines the prognosis is radical surgery. For the treatment of unresectable leiomyosarcoma, chemotherapy and targeted therapy are used. One of the alternative options for drug treatment with uterine leiomyosarcoma is hormone therapy. its use is possible with a positive status of estrogen and progesterone receptors in the tumor. The presence of steroid hormone receptor expression is a favorable prognostic factor. This article presents our own analysis of the frequency of expression of estrogen and progesterone receptors and the frequency of hormone therapy in leiomyosarcoma of different anatomic localization.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лейомиосаркома</kwd><kwd>рецепторы эстрогена</kwd><kwd>рецепторы прогестерона</kwd><kwd>гормонотерапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>leiomyosarcoma</kwd><kwd>estrogen receptors</kwd><kwd>progesterone receptors</kwd><kwd>hormone therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Billingsley K.
