Case histories of 621 persons with primary multiple malignancies were analyzed. In 329 of them at least one of the tumors was located in the digestive organs, and in 104 (16,7%) patients tumors of this localization were primary. 100 patients were diagnosed with 2 tumors, 4 patients had 3 tumors. Among the patients there were 69 male and 35 female patients. The average age of patients at the time of detection of the first tumor was 53.6 and 62.9 years at detection of the second tumor.</p></abstract><trans-abstract xml:lang="ru"><p>Нами изучены особенности течения и результаты лечения метахронных первично-множественных злокачественных новообразований с локализацией первой опухоли в органах пищеварения; вторая и (или) третья опухоли находились как в них, так и в органах других систем. Проанализированы истории болезни 621 лица с первично-множественными злокачественными новообразованиями. У 329 из них хотя бы одна из опухолей располагалась в органах пищеварения, причем у 104 (16,7%) больных опухоли указанной локализации были первичными. У 100 больных диагностированы по 2 опухоли, у 4 — по 3. Среди больных было 69 мужчин и 35 женщин. Средний возраст больных в момент выявления первой опухоли составил 53,6, при выявлении второй — 62,9 года.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list/></back></article>
