Исследование PRIME продемонстрировало увеличение медианы общей выживаемости (МОВ) при лечении панитумумабом (П) в сочетании с FOLFOX4 по сравне нию с FOLFOX4–26,0 vs 20,2 мес (р = 0,04). В исследовании РЕАК у этой же категории больных сравнительно изучены 2 комбинации в качестве 1-й линии лечения: П + FOLFOX4 и бевацизумаб (Б) + FOLFOX: достигнуто достоверное увеличение медианы выживаемости без прогрессирования (13,1 vs 9,5 мес, p = 0,03) и статистически незначимое увеличение МОВ (41,3 vs 28,9 мес, p = 0,058). Исследование FIRE показало преимущество цетуксимаба + FOLFIRI по сравнению с Б + FOLFIRI по МОВ – 33,1 vs 25,6 мес (р = 0,011). Во всех исследованиях ретроспективно изучены дополнительные мутации гена RAS, позволяющие выявить более узкую подгруппу больных, нуждающихся в терапии моноклональными антителами – ингибиторами EGFR.</p></trans-abstract><kwd-group xml:lang="en"><kwd>metastatic colorectal cancer</kwd><kwd>EGFR inhibitors</kwd><kwd>targeted therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метастатический колоректальный рак</kwd><kwd>ингибиторы EGFR</kwd><kwd>таргетная терапия</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.
