To study the pattern of complex chromosome damages (CCD) in acute leukemias (AL) and their place in the development of post-transplant recurrences (PTR) of AL. Materials and methods. Cytogenetic and partially molecular biological studies of bone marrow cells were conducted in 10 patients with PTR. Of them, 6 patients were diagnosed as having acute lymphoblastic leukemia (ALL), including T-ALL and Ph-positive ALL in 2 and 4 patients, respectively; and 4 patients had acute non-lymphoblastic leukemia (ANLL), including one case secondarily induced by previous polychemotherapy (PCT) and irradiation. The standard G-band staining technique complemented by multicolor fluorescence in situ hybridization in one of the cases was used. Results. It was shown that CCD had the similar pattern in 4 patients before transplantation and in PTR, progressed in 4 more patients, was absent or unnoticed in the early stage of the disease. The other recurrent chromosomal abnormalities that are worthy of notice are as follows: a) the presence of two Ph chromosomes in the cells of two of the 4 patients with Ph+ ALL; b) the frequent involvement of chromosome pairs 9, 19, 5, and 7 into the numerical and structural rearrangements. Conclusion. The important feature of PTR of AL is cellular CCDs, a portion of which is clearly related to previous PCT and may be of pathogenetic value for the development of recurrences.</p></abstract><trans-abstract xml:lang="ru"><p>Резюме. Цель исследования. Изучить характер сложных повреждений хромосом (СПХ) при острых лейкозах (ОЛ) и их место в формировании посттрансплантационных рецидивов (ПТР) ОЛ. Материалы и методы. Проведены цитогенетические и частично молекулярно-биологические исследования клеток костного мозга 10 больных с ПТР. Из них у 6 был диагноз острого лимфобластного лейкоза (ОЛЛ), в том числе у 2 - Т-ОЛЛ и у 4 - Ph-позитивный ОЛЛ, а у 4 больных - острый нелимфобластный лейкоз, включая один вторично индуцированный предшествующей полихимиотерапией и облучением. Использована стандартная техника окрашивания хромосом на G-сегменты, которая в одном из наблюдений была дополнена многоцветным in situ окрашиванием (M-FISH). Результаты. Показано, что СПХ у 4 больных до трансплантации и в ПТР имели идентичный характер, у 4 других прогрессировали, а в 2 наблюдениях на ранних этапах заболевания отсутствовали или не были замечены. Из других повторяющихся нарушений хромосом заслуживают внимания следующие: а) наличие двух Ph-хромосом в клетках двух из 4 больных с Ph+ ОЛЛ; б) частое вовлечение в численные и структурные перестройки 9, 19, 5 и 7-й пар хромосом (60, 40, 30 и 20% больных соответственно). Заключение. Важной особенностью ПТР ОЛ является наличие в клетках СПХ, часть из которых отчетливо связаны с предшествующей ПХТ и могут иметь патогенетическое значение при формировании рецидивов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acute leukemias</kwd><kwd>allogeneic hematopoietic stem cell transplantation</kwd><kwd>post-transplant recurrences</kwd><kwd>complex chromosome rearrangements</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>острые лейкозы</kwd><kwd>аллогенная трансплантация гемопоэтических стволовых клеток</kwd><kwd>посттрансплантационные рецидивы</kwd><kwd>сложные перестройки хромосом</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hartwig M., Ocheni S., Asenova S. et al.
