Обсуждены данные по результатам сочетания таргетных моноклональных антител с различными режимами химиотерапии. Освещены современные исследования по тактике выбора последовательности таргетной терапии у больных с метастатическим заболеванием. Также рассмотрены вопросы влияния различных факторов на эффективность терапии теми или иными препаратами и их места в выборе терапии при раке толстой кишки.</p></abstract><trans-abstract xml:lang="en"><p>In this review we analyzed results of studies concerning the choice of first and subsequent lines of therapy in patients with metastatic colon cancer. We discussed data of various combinations of monoclonal antibodies with different chemotherapeutic regimens. Also we discussed modern preclinical and clinical trials concerning strategy of choice of targeted therapy sequence in patients with metastatic disease. We considered the impact of various molecular and clinical factors on the effectiveness of drugs and determined their application for therapy choice for colon cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак толстой кишки</kwd><kwd>таргетная терапия</kwd><kwd>химиотерапия</kwd><kwd>рандомизированные исследования</kwd><kwd>последовательность режимов терапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>targeted therapy</kwd><kwd>chemotherapy</kwd><kwd>sequence of chemotherapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tournigand C., Andre T., Achille E. et al.
