Although the use of targeted drugs with a more favorable toxicity profile than cytotoxic drugs is more attractive, the use of cytotoxic therapy generally demonstrates better results. Currently, different morphological types of soft tissue sarcomas require different therapies. Necessity of carrying out of 2<sup>nd</sup> and more lines of therapy at SMT does not raise doubts, however now clear algorithms of treatment are not yet developed.<italic>Objective. </italic>To evaluate the efficacy of trabectedin, pazopanib and a combination of gemcitabine and docetaxel as a second line of treatment for patients with soft tissue sarcomas <italic>Materials and methods. </italic>106 patients with different STS were divided into three treatment groups: 1st group of patients (n=43) received trabectedin 1,5 mg/m2 as a 24-hour continuous intravenous infusion every 3 weeks; The 2nd group of patients (n=37) received pazopanib 800 mg orally once a day; third group of patients (n=26) received combination of gemcitabine and docetaxel (GemTax): gemcitabine 900 mg/m2 IV in a 1,5 hour infusion on days 1 and 8, docetaxel 100 mg/m2 IV the 8th day every 3 weeks with G-CSF support. Tumor assessment was done according to RECIST 1.1 criteria.<italic>Results. </italic>The efficacy of the combination of gemcitabine and docetaxel was evaluated in 26 patients: CR – 1 patient (3,8%), PR – 6 patients (23,1%), SD – 13 patients (50%), PD – 6 patients (23,1%). Thus, tumor control rate (complete remission, partial remission, stabilization) was 76,9%. The median time to progression was 6,7 months. The median overall survival was 15,4 months.The effectiveness of pazopanib was evaluated in 37 patients: CR – 0%, PR – 4 patients (10,8%), SD – 27 patients (73%), PD – 6 patients (16,2%). Thus, tumor control rate was 83,8%. The median time to progression was 7 months. Median overall survival was 14,5 months.Efficacy of trabectedin was evaluated in 43 patients: CR – 0%, PR – 4 patients (9,3%), SD – 21 patients (48,8%), PD – 18 patients (41,9%). Thus, tumor control rate was 58,1%. The median time to progression was 2,3 months. Median overall survival was 10,3 months. The toxicity profile did not differ from the world published data.<italic>Conclusions. </italic>When comparing chemotherapy regimens, we obtained the following data – for leiomyosarcomas and angiosarcomas, the use of high-dosage chemotherapy GemTax as the second line showed the highest indices of median PFS 10 and 8,2 months, respectively. The median OS was 14,7 and 15,3 months, respectively. For synovial sarcomas, the use of pazopanib showed the longest median PFS equal to 14 months. Median OS was 15,5 months, so pazopanib the most preferable regimen of second line therapy. In case of liposarcomas, the use of trabectedin in the second line shows the best results: the median PFS was 2,1 months, and the median OS was 8,3 months. With insensitive and weakly sensitive subtypes of soft tissue sarcomas to standard chemotherapy regimens, pazopanib shows high rates of median PFS and OS. Therefore, the use of pazopanib is possible both in the second line of therapy, and also in the front line of treatment for chemoresistant subtypes of advanced STS.</p></abstract><trans-abstract xml:lang="ru"><p>Системное лечение пациентов с диссеминированными саркомами мягких тканей (СМТ) может включать цитотоксическую химиотерапию и/или таргетную терапию. Несмотря на более благоприятный профиль токсичности таргетных препаратов по сравнению с цитостатической терапией, применение химиотерапии, как правило, демонстрирует более  высокие результаты. В настоящее время разные морфологические типы СМТ требуют разной терапии. Необходимость проведения 2-й и более линий терапии при СМТ не вызывает сомнений, однако в настоящее время не разработано четких алгоритмов лечения.<italic>Цель работы. </italic>Оценить и сравнить эффективность трабектедина, пазопаниба и комбинации гемцитабина с доцетакселом во 2-й линии лечения больных СМТ.<italic>Материалы и методы. </italic>В исследование включены 106 пациентов с различными подтипами СМТ, выделены три группы лечения: 1-я группа пациентов (n=43) получала терапию трабектедином в дозе 1,5 мг/м2 в виде 24-часовой непрерывной внутривенной инфузии каждые 3 нед; 2-я группа пациентов (n=37) получала пазопаниб в дозе 800 мг внутрь 1 раз в сутки непрерывно; 3-я группа пациентов (n=26) получала комбинацию гемцитабина и доцетаксела (GemTax): гемцитабин в дозе 900 мг/м2 в/в 1,5-часовая инфузия в 1-й и 8-й дни, доцетаксел в дозе 100 мг/м2 в/в в 8-й день каждые 3 нед с поддержкой КСФ. Оценка эффекта лечения производилась по критериям RECIST 1.1. Оценка токсичности лечения проводилась по критериям NCCN CTC AE версии 4.03.<italic>Результаты. </italic>Эффективность комбинации гемцитабина и доцетаксела оценена у 26 больных: полная ремиссия – 1 (3,8%) пациент, частичная ремиссия – 6 (23,1%) пациентов, стабилизация процесса – 13 (50%) пациентов, прогрессирование – 6 (23,1%) пациентов. Таким образом, контроль роста опухоли (полная ремиссия, частичная ремиссия, стабилизация) составил 76,9%. Медиана времени без прогрессирования составила 6,7 мес. Медиана общей выживаемости пациентов – 15,4 мес. Эффективность пазопаниба оценена у 37 больных: полная ремиссия – не отмечено (0%), частичная ремиссия – 4 (10,8%) пациента, стабилизация процесса – 27 (73%) пациентов, прогрессирование – 6 (16,2%) пациентов. Таким образом, контроль роста опухоли составил 83,8%. Медиана времени без прогрессирования составила 7 мес. Медиана общей выживаемости пациентов – 14,5 мес. Эффективность трабектедина оценена у 43 больных: полная ремиссия – не отмечено (0%), частичная ремиссия – 4 (9,3%) пациента, стабилизация процесса – 21 (48,8%) пациент, прогрессирование – 18 (41,9%) пациентов. Таким образом, контроль роста опухоли составил 58,1%. Медиана времени без прогрессирования составила 2,3 мес. Медиана общей выживаемости пациентов – 10,3 мес. Профиль токсичности не отличался от мировых опубликованных данных.<italic>Выводы. </italic>При сравнении режимов химиотерапии мы получили следующие данные: при лейомиосаркомах, ангиосаркомах применение высокодозной химиотерапии GemTax в качестве 2-й линии показывает наибольшие показатели МВБП: 10 и 8,2 мес соответственно, МОВ пациентов составила 14,7 и 15,3 мес соответственно. При синовиальных саркомах применение пазопаниба показало наиболее длительную МВБП, равную 14 мес. МОВ составила 15,5 мес, поэтому в качестве 2-й линии наиболее предпочтительно применение данного режима. При липосаркомах применение трабектедина во 2-ю линию показывает наилучшие результаты: МВБП составила 2,1 мес, МОВ – 8,3 мес. При нечувствительных и слабочувствительных подтипах СМТ пазопаниб показывает высокие показатели МВБП и МОВ, поэтому применение пазопаниба возможно как во 2-ю линию терапии, а также в 1-ю линию лечения для химиорезистентных подтипов диссеминированных СМТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soft tissue sarcoma</kwd><kwd>chemotherapy</kwd><kwd>targeted therapy</kwd><kwd>pazopanib</kwd><kwd>gemcitabine</kwd><kwd>docetaxel</kwd><kwd>trabectedin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома мягких тканей</kwd><kwd>химиотерапия</kwd><kwd>таргетная терапия</kwd><kwd>пазопаниб</kwd><kwd>гемцитабин</kwd><kwd>доцетаксел</kwd><kwd>трабектедин</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.
