Anorectal melanoma is a rare malignancy without established standard treatment.<bold>Aim</bold>. To analyse the Russian Colorectal Cancer Society melanoma registry and to assess optimal surgery with regard to the extent of the disease.<bold>Materials and methods</bold>. A retrospective analysis of the Russian Colorectal Cancer Society registry was carried out during 2000–2020. Patients with cutaneous melanoma colonic metastases as well as patients with less than 6 months follow-up were excluded. Basic patient group characteristics, overall and disease-free survival (were analyzed depending on disease stage (by A. Stefanou) and surgery type.<bold>Results</bold>. 16 patients had stage I–IIA, 24 – stage IIB, 29 patients – stage III and 24 patients – stage IV disease. Wide local excision was performed in 15 (93.8 %) patients with stage I–IIA, 15 (62.5 %) patients with stage IIB, 2 (6.9 %) patients with stage III, and 8 (33.3 %) patients with stage IV disease. Abdomino-perineal excision (APE) was performed in 0 patients with stage I–IIA, 7 (29.2 %) patients with stage IIB, 22 (75.9 %) patients with stage III, and 7 (29.2 %) patients with stage IV disease. 2-year overall survival was 74.5 % in stage I–IIA, 49.4 % in stage IIB, 64.3 % in stage III, and 10.4 % in stage IV disease; 2-year disease-free survival was 67 %, 23,4 %, 34,1 % in stage I–IIA, IIB, III disease accordingly. Median overall survival was 17.8 months, 38.3 months and 27.9 months for non-surgical treatment, wide local excision and APR in non-metastatic patients accordingly. Median disease-free survival was 6.0 months, 14.1 months and 12.0 months for non-surgical treatment, wide local excision and APR in non-metastatic patients accordingly.<bold>Conclusions</bold>. APR should be considered in patients with stage IIB and stage III (by A. Stefanou) anorectal melanoma. Wide local excision is the preferred treatment in other patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Аноректальная меланома – редкое злокачественное новообразование, для которого отсутствуют общепринятые стандарты лечения.<bold>Цель исследования</bold> – анализ данных реестра редких заболеваний Российского общества специалистов по колоректальному раку по аноректальной меланоме и оценка оптимальной тактики лечения при различной степени распространенности заболевания.<bold>Материалы и методы</bold>. Проведен ретроспективный анализ реестра аноректальных меланом Российского общества специалистов по колоректальному раку за 2000–2020 гг. Из анализа исключали пациентов с метастазами меланомы кожи в толстую кишку, пациентов, прослеженных &lt;6 мес. Анализировали основные клинические характеристики, характер метастазирования при различных стадиях, общую и безрецидивную выживаемость в зависимости от стадии по A. Stefanou и вида хирургического лечения.<bold>Результаты</bold>. В исследуемой группе было 16 пациентов с I–IIA стадией, 24 пациента с IIB стадией, 29 пациентов с III стадией и 24 пациента с IV стадией. Трансанальное иссечение было выполнено 15 (93,8 %) пациентам с I–IIA стадией, 15 (62,5 %) пациентам с IIB стадией, 2 (6,9 %) пациентам с III стадией и 8 (33,3 %) пациентам с IV стадией. Брюшно-промежностная экстирпация (БПЭ) прямой кишки была выполнена 7 (29,2 %) пациентам с IIB стадией, 22 (75,9 %) пациентам с III стадией, 7 (29,2 %) пациентам с IV стадией и не была выполнена ни одному из пациентов с I–IIA стадией. Двухлетняя общая выживаемость составила 74,5; 49,4; 64,3 и 10,4 % при I–IIA, IIB, III и IV стадии соответственно, 2-летняя БРВ – 67,0; 23,4 и 34,1 % при I–IIA, IIB и III стадии соответственно. Медиана общей выживаемости при неметастатических случаях составила 17,8; 38,3 и 27,9 мес для нехирургического лечения, трансанального иссечения и БПЭ прямой кишки соответственно, медиана безрецидивной выживаемости – 6,0; 14,1 и 12,0 мес.<bold>Выводы</bold>. Выполнение БПЭ прямой кишки следует рассматривать у пациентов с IIB и III стадиями аноректальной меланомы по A. Stefanou. У остальных пациентов при технической возможности следует выполнять трансанальное иссечение.</p></trans-abstract><kwd-group xml:lang="en"><kwd>anorectal melanoma</kwd><kwd>anal melanoma</kwd><kwd>rectal melanoma</kwd><kwd>wide local excision</kwd><kwd>abdominoperineal excision</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>аноректальная меланома</kwd><kwd>меланома анального канала</kwd><kwd>меланома прямой кишки</kwd><kwd>трансанальное иссечение</kwd><kwd>брюшно-промежностная экстирпация прямой кишки</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.
