Pazopanib – multityrosine kinase inhibitor of angiogenesis, targeted to receptors VEGFR-1, -2 and -3, and receptor and PDGFR-A and -B, c-Kit, which can provide long-term stabilization and objective responses in sarcomas.<italic>Objective. </italic>Aim of the study was to evaluate the efficacy and safety of pazopanib in treatment of patients with soft tissue sarcomas.<italic>Materials and Methods. </italic>42 patients with metastatic soft tissue sarcomas in age from 19 till 78 years old after one or more lines of chemotherapy were enrolled in the study. Pazopanib was used in a dose of 800 mg Po daily.<italic>Results. </italic>Efficacy of pazopanib was evaluated in 40 patients: CR – none, PR – in 1 patient (2.5%), SD – in 30 patients (75%), PD – in 9 patients (22.5%). Thus, control of tumor growth (complete remission, partial remission, stabilization) was achieved in 77.5%. The median time to progression was 8.3 months. The median overall survival has not been reached. Toxicity was mild and durable and almost the same as were reported in previous worldwide studies.<italic>Conclusions. </italic>Based on the data obtained in this study pazopanib can be used as the second or more line of therapy. In some clinical cases efficacy of pazopanib was reported in patients with rare chemoresistant subtypes of STS.</p></abstract><trans-abstract xml:lang="ru"><p>Саркомы мягких тканей относятся к опухолям с высокой васкуляризацией, где ангиогенез играет важную роль в их развитии и метастазировании. большинство сарком мягких тканей имеют сложный генетический профиль, с несколькими мутациями или аберрациями, которые затрудняют возможности лечения ингибиторами киназ.Пазопаниб относится к мультитирозинкиназным ингибиторам ангиогенеза, нацеленный на рецепторы VEGFR-1, -2 и -3 и рецептор PDGFR-A и -B и c-Kit, который может обеспечить длительную стабилизацию и объективные ответы при саркомах.<italic>Цель работы. </italic>оценить эффективность пазопаниба в лечении больных саркомами мягких тканей.<italic>Материалы и методы.</italic> в исследование были включены 42 пациента с диссеминированными саркомами мягких тканей в возрасте от 19 до 78 лет, получавших одну или более линий химиотерапии. Пазопаниб применялся в дозе 800 мг, внутрь, 1 раз в сут, ежедневно. оценка эффекта лечения производилась по критериям RECIST 1.1.<italic>Результаты. </italic>Эффективность применения пазопаниба оценена у 40 больных: полная ремиссия – не отмечено, частичная ремиссия – у 1 пациента (2,5%), стабилизация процесса – у 30 пациентов (75%), прогрессирование – у 9 пациентов (22,5%). таким образом, контроль роста опухоли (полная ремиссия, частичная ремиссия, стабилизация) составил 77,5%. медиана времени до прогрессирования составила 8,3 мес. медиана общей выживаемости не достигнута. Профиль токсичности не отличался от мировых опубликованных данных.<italic>Выводы.</italic> на основании данных, полученных в нашем исследовании, можно сделать вывод о высокой эффективности пазопаниба в качестве второй и более линий терапии больных СМТ. в отдельных клинических наблюдениях отмечена эффективность пазопаниба у пациентов с редкими гистологическими подтипами СМТ со слабой чувствительностью к стандартной химиотерапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soft tissue sarcoma</kwd><kwd>targeted therapy</kwd><kwd>pazopanib</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома мягких тканей</kwd><kwd>таргетная терапия</kwd><kwd>пазопаниб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
