N. Blokhin Russian Cancer Research Center in the treatment of relapses of gestational trophoblastic neoplasias (GTN).</p> <p><bold>Materials and methods. </bold>We performed a retrospective analysis of medical case histories at the N. N. Blokhin Russian Cancer Research Center from 1996 until 2019. 545 patients with GTN were treated. Relapses occurred in 25 (4.6%) patients: 8 (2.1%) patients with low risk of resistance (6 (75%) – early relapses and 2 (25%) – late relapses) and 17 (10%) patients with high risk of resistance (11 (65%) – early relapses and 6 (35%) – late relapses). Treatment of relapses was done by standard chemotherapy regimens (Dactinomycin 500mcg in days 1–5, EMA-CO, EMA-EP). Different surgical interventions and radiosurgery were used in some cases additionally.</p> <p><bold>Results.</bold> Out of 6 patients with early relapses of low-risk GTN, 5 were cured with chemotherapy and one patient by lung resection only. Two patients with late relapses of low-risk GTN were cured with chemotherapy (EMA-CO) and hysterectomy/resection of uterus to achieve complete remission. As a result, all patients with relapses of low-risk GTN were cured, mainly (88%) by chemotherapy. Among 11 patients with early relapses of high-risk GTN, complete remission was achieved in 6 (55%) cases: in 2 patients as a result of EMA-EP chemotherapy, other patients needed combined approaches (chemotherapy + surgery). Three patients with recurrent course continue treatment, two patients died of progression. Of the 6 patients with late relapses of high-risk GTN, 4 (66%) patients were managed mainly through combined treatment (surgery + chemotherapy) and were cured. One patient continues treatment for more than 4 years, and one patient died of progression. In total, out of 17 patients with high-risk relapses, complete remission was achieved in 10 (59%) as a result of combined treatment in the majority of cases (80%).</p> <p><bold>Conclusion.</bold> The optimal method of treatment for patients with relapses of low-risk GTN is chemotherapy; and for high-risk GTN – combined approaches (chemotherapy + surgery)</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования:</bold> представить собственный опыт лечения больных с рецидивами злокачественных трофобластических опухолей (ЗТО).</p> <p><bold>Материалы и методы.</bold> Выполнен ретроспективный анализ историй болезни больных, подвергшихся лечению в клинике с 1996 по 2019 г. Общее число больных с ЗТО составило 545. Рецидивы ЗТО возникли у 25 (4,6%) пациенток: у 8 (2,1%) больных с низким риском резистентности (6 (75%) из них – ранние рецидивы и 2 (25%) – поздние) и у 17 (10%) больных – с высоким риском (11 (65%) – ранние и 6 (35%) – поздние). Лечение рецидивов проводилось стандартными режимами химиотерапии (дактиномицин 500 мкг в дни 1-5, ЕМА-СО, ЕМА-ЕР). Дополнительно выполнялись хирургические вмешательства, радиохирургия.</p> <p><bold>Результаты.</bold> Из 6 больных с ранними рецидивами ЗТО низкого риска 5 излечены с помощью химиотерапии и одна пациентка в результате резекции лёгкого. Две пациентки с поздними рецидивами излечены с помощью химиотерапии (ЕМА-СО) и гистерэктомии/ гистерорезекции. Излечены 100% больных с рецидивами ЗТО низкого риска преимущественно (88%) с помощью химиотерапии. Среди 11 больных с ранними рецидивами ЗТО высокого риска полная ремиссия достигнута в 6 (55%) наблюдениях: у 2 больных в результате химиотерапии ЕМА-ЕР, у остальных – с помощью комбинированного лечения. Три пациентки с рецидивирующим течением продолжают лечение, две пациентки умерли от прогрессирования. Из 6 больных с поздними рецидивами ЗТО высокого риска излечены 4 (66%) больных преимущественно с помощью комбинированного лечения (операция + химиотерапия). Одна пациентка продолжает лечение более 4 лет, одна пациентка умерла от прогрессирования. Всего из 17 больных с рецидивами ЗТО высокого риска полная ремиссия достигнута у 10 (59%) в большинстве наблюдений (80%) – в результате комбинированного лечения.</p> <p><bold>Заключение. </bold>Оптимальным методом лечения больных с рецидивами ЗТО низкого риска является химиотерапия, а для больных с высоким риском – комбинированный метод (химиотерапия + хирургия).</p></trans-abstract><kwd-group xml:lang="en"><kwd>gestational trophoblastic neoplasia</kwd><kwd>relapses</kwd><kwd>chemotherapy</kwd><kwd>combined treatment</kwd><kwd>choriocarcinoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>злокачественные трофобластические опухоли</kwd><kwd>рецидивы</kwd><kwd>химиотерапия</kwd><kwd>комбинированное лечение</kwd><kwd>хориокарцинома</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">Wang J., Short D., Sebire N.
