Colon cancer is one of the most common malignancies worldwide. At the same time, about 30% of patients at the time of diagnosis have a disseminated tumor process. Despite the progress in pharmacotherapy of patients with metastatic colorectal cancer over the past 15 years, 5-year survival is still relatively low. Panitumumab, a fully human monoclonal antibody that blocks the epidermal growth factor receptor (EGFR), significantly increases the life expectancy of patients with this pathology. The drug is approved for the treatment of RAS wild-type advanced colorectal cancer in combination with chemotherapy as the first- or second-line of therapy or as monotherapy for chemoresistant cancer. Description of the clinical case. We present a clinical case of the treatment of a 71-year-old patient with disseminated sigmoid colon adenocarcinoma and progression after three lines of therapy. The patient underwent 12 cycles of chemotherapy according to the FOLFOX-6 regimen in combination with panitumumab. The maximum treatment effect was partial regression. Conclusion. Our clinical experience demonstrates that therapy with panitumumab in combination with FOLFOX-6 chemotherapy allows to achieve an objective effect, increase the time to progression and overall survival in previously treated patients with metastatic colon cancer.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Рак толстой кишки - одно из самых распространенных злокачественных новообразований в мире. При этом около 30% пациентов на момент постановки диагноза имеют диссеминированный опухолевый процесс. Несмотря на прогресс в лекарственном лечении больных метастатическим колоректальным раком за последние 15 лет, 5-летняя выживаемость по-прежнему остается относительно невысокой. Панитумумаб - полностью человеческое моноклональное антитело, блокирующее рецептор эпидермального фактора роста (EGFR), достоверно увеличивает продолжительность жизни пациентов с данной патологией. Препарат одобрен для лечения распространенного колоректального рака с «диким» типом гена RAS в комбинации с химиотерапией в качестве первой или второй линий терапии либо в монорежиме при химиорезистентном заболевании. Описание клинического случая. Мы приводим клинический случай лечения пациентки 71 года с диссеминированной аденокарциномой сигмовидной кишки, у которой отмечено дальнейшее прогрессирование заболевания после трех линий лекарственного лечения. Больной проведено 12 циклов химиотерапии по схеме FOLFOX-6 в сочетании с панитумумабом. Максимальный эффект лечения - частичный регресс. Заключение. Наш клинический опыт демонстрирует, что терапия панитумумабом в комбинации с химиотерапией FOLFOX-6 позволяет достигать объективного эффекта, увеличивать время до прогрессирования и общую выживаемость у ранее предлеченных больных метастатическим раком толстой кишки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>metastatic colorectal cancer</kwd><kwd>targeted therapy</kwd><kwd>EGFR inhibitors</kwd><kwd>panitumumab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метастатический колоректальный рак</kwd><kwd>таргетная терапия</kwd><kwd>EGFR-ингибиторы</kwd><kwd>панитумумаб</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lopez-Gomez M., Merino M., Casado E.
