A feature of the epidemiology of RCC is its predominant prevalence both in the morbidity structure of the elderly (60 years and older) (3.7 %) and in the young age group of 30–59 years (4.5 %).</p> <p>In the present rare clinical observation of a patient with a late recurrence of RCC 10 years after nephrectomy, salvage surgical treatment (metastasectomy), rapid progression on first-line sunitinib targeted therapy and subsequent long-term durable tumor response to targeted therapy with multikinase inhibitor cabozantinib.</p> <p>In this observation of a patient with multifocal visceral metastases in the 2<sup>nd</sup> line, stabilization of disease was achieved during 4 years cabozantinib monotherapy, treatment continues to the present. Despite the extremely long continuous intake of cabozantinib at full dose and patient’s morbidity, no dose reduction or temporary breaks in therapy were required. Patient tolerates treatment satisfactorily with controlled adverse events – II grade drug-induced steatohepatitis with moderate cytolysis syndrome, I grade toxic dermatitis, I grade nause. Patient’s quality of life is preserved.</p></abstract><trans-abstract xml:lang="ru"><p>Почено-клеточный рак (ПКР) остается одной из ведущих онкологических патологий. Особенностью эпидемиологии ПКР является его превалирующая распространенность как в структуре заболеваемости лиц пожилого возраста (60 лет и старше) (3,7 %), так и в молодой возрастной группе 30–59 лет (4,5 %).</p> <p>Представляем клиническое наблюдение редкого случая пациента с поздним рецидивом ПКР через 10 лет после нефрэктомии, проведением сальважного хирургического лечения (метастазэктомии), быстрым прогрессированием на фоне таргетной терапии сунитинибом и последующим длительным устойчивым опухолевым ответом на терапию мультикиназным ингибитором кабозантинибом.</p> <p>У пациента с мультифокальными висцеральными метастазами во 2-й линии зарегистрирована стабилизация опухолевого процесса на протяжении 4 лет приема кабозантиниба, лечение продолжается по настоящее время. Несмотря на сверхдолгий непрерывный прием кабозантиниба в полной дозе и соматическую отягощенность пациента, редукции дозы или перерывов в терапии не потребовалось. Пациент переносит лечение удовлетворительно с нежелательными явлениями, медикаментозно купируемыми, – лекарственно-индуцированным стеатогепатитом II степени с умеренно выраженным синдромом цитолиза, токсическим дерматитом I степени, тошнотой I степени. Качество жизни пациента сохранено.</p></trans-abstract><kwd-group xml:lang="en"><kwd>clear cell renal cell carcinoma</kwd><kwd>late recurrence after nephrectomy</kwd><kwd>metastasectomy</kwd><kwd>visceral metastases of renal cell carcinoma</kwd><kwd>sunitinib</kwd><kwd>cabozantinib</kwd><kwd>durable response</kwd><kwd>long-term stabilization</kwd><kwd>adverse events</kwd><kwd>progression-free survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>светлоклеточный почечно-клеточный рак</kwd><kwd>поздний рецидив после нефрэктомии</kwd><kwd>метастазэктомия</kwd><kwd>висцеральный метастаз почечно-клеточного рака</kwd><kwd>сунитиниб</kwd><kwd>кабозантиниб</kwd><kwd>устойчивый ответ</kwd><kwd>длительная стабилизация</kwd><kwd>нежелательное явление</kwd><kwd>выживаемость без прогрессирования</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Злокачественные новообразования в России в 2024 году (заболеваемость и смертность).
