Almost 1/4 of patients with CRC have metastases at the initial presentation. The survival rate of this group of patients remains low. With the onset of the COVID-19 pandemic, cancer patients have faced difficulties in getting diagnosis or treatment, which could potentially lead to an increase in late-stage tumors and mortality. This situation required changes in approaches to the treatment of cancer patients, such as replacing drugs with tablet forms, schemes with long intervals, and much more. It is known that about 50% of patients with metastatic colorectal cancer survive in satisfactory condition until the 3rd line drug therapy or longer. One of the main drugs for this category of patients is regorafenib, which, thanks to the tablet formulation, has become especially important in the COVID-19 pandemic. In numerous clinical studies, the drug showed an increase in patient overall survival and good safety profile. In addition, there is growing evidence of the effect of regorafenib on tumor sensitivity to treatment with platinum drugs, irinotecan, and EGFR inhibitors.</p></abstract><trans-abstract xml:lang="ru"><p>Колоректальный рак (КРР) – одно из ведущих онкологических заболеваний по распространенности и смертности. Почти 1/4 пациентов с КРР при первичном обращении имеют метастазы. Выживаемость этой группы пациентов остается невысокой. С наступлением пандемии COVID-19 онкологические пациенты столкнулись с затруднениями в получении диагностики или лечения, что потенциально может привести к росту выявленных на поздней стадии опухолей и увеличению смертности. Подобная ситуация потребовала изменений в подходах к лечению онкологических пациентов – замена препаратов на таблетированные формы, схемы с большими интервалами и многое другое. Известно, что около 50% пациентов с метастатическим КРР доживают в удовлетворительном состоянии до 3-й и более линии лекарственной терапии. Одним из основных препаратов для этой категории пациентов является регорафениб, который благодаря таблетированной форме стал особенно актуален в пандемию COVID-19. В многочисленных клинических исследованиях препарат показал повышение общей выживаемости пациентов с хорошим профилем безопасности. Кроме того, накапливаются данные о влиянии регорафениба на чувствительность опухоли к терапии препаратами платины, иринотеканом и ингибиторами EGFR.</p></trans-abstract><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>COVID-19</kwd><kwd>chemotherapy</kwd><kwd>targeted therapy</kwd><kwd>regorafenib</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>COVID-19</kwd><kwd>химиотерапия</kwd><kwd>таргетная терапия</kwd><kwd>регорафениб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rawla P, Sunkara T, Barsouk A.
