Роль периоперационной регионарной химиотерапии в лечении больных колоректальным раком с метастатическим поражением печени в группе неблагоприятного прогноза

Abstract

Проведен анализ результатов обширных резекций печени с периоперационной регионарной химиотерапией (ХТ) 120 больным с резектабельными метастазами колоректального рака в печень. Множественные метастазы наблюдались у 54 (45 %) больных, билобарное поражение печени у 72 (60 %), 26 (22 %) больных с внепеченочными метастазами. В качестве предоперационной ХТ одной группе лечение проводилось в режиме FOLFOX, другой в этом же режиме в сочетании с бевацизумабом. Добавление к лечению бевацизумаба сопровождалось ростом объективного эффекта до 66 % по сравнению с группой без бевацизумаба 44 % и частоты лекарственного патоморфоза в опухоли 3-й степени 59 % по сравнению с 5 % без бевацизумаба, но не привело к достоверному повышению показателей отдаленной выживаемости: 5-летняя выживаемость 16 ± 8 %, медиана 35 мес по сравнению с 21 ± 6 % и медианой 29 мес без бевацизумаба. Дооперационная регионарная внутриартериальная ХТ не привела к увеличению интраоперационной кровопотери и частоты послеоперационных осложнений. Проведение периоперационной ХТ позволило перевести 6 (5 %) пациентов в резектабельное состояние.

In this study we have analyzed 120 cases of extensive liver resection with preand postoperative regional chemotherapy in poor prognosis patients: 54 (45 %) of them had multiple liver metastases, 72 (60 %) had bilobar lesions, 26 (22 %) had extrahepatic metastases. Adding bevacizumab to preoperative regional intra-arterial chemotherapy (FOLFOX) has increased objective response rate up to 65 vs 44 % in group without bevacizumab and grade III morphological response rate up to 59 vs 5 % in group without bevacizumab. Difference in overall survival in both groups was not statistically significant: 5-year survival was 16 ± 8 % and 21 ± 6 %, median survival was 35 months and 29 months in groups with or without bevacizumab, respectively. Preoperative regional intra-arterial chemotherapy has not increased the rate of bleeding and postoperative complications.
